    To investigate the features of corneal epithelial thickness topography with Fourier-domain optical coherence tomography (OCT) in dry eye patients. In this cross-sectional study, 100 symptomatic dry eye patients and 35 normal subjects were enrolled. All participants answered the ocular surface disease index questionnaire and were subjected to OCT, corneal fluorescein staining, tear breakup time, Schirmer 1 test without anesthetic (S1t), and meibomian morphology. Several epithelium statistics for each eye, including central, superior, inferior, minimum, maximum, minimum - maximum, and map standard deviation, were averaged. Correlations of epithelial thickness with the symptoms of dry eye were calculated. The mean (±SD) central, superior, and inferior corneal epithelial thickness was 53.57 (±3.31) μm, 52.00 (±3.39) μm, and 53.03 (±3.67) μm in normal eyes and 52.71 (±2.83) μm, 50.58 (±3.44) μm, and 52.53 (±3.36) μm in dry eyes, respectively. The superior corneal epithelium was thinner in dry eye patients compared with normal subjects (p = 0.037), whereas central and inferior epithelium were not statistically different. In the dry eye group, patients with higher severity grades had thinner superior (p = 0.017) and minimum (p dry eye corneal epithelium was thinner than normal eyes in the superior region. In more severe dry eye disease patients, the superior and minimum epithelium was much thinner, with a greater range of map standard deviation.

    2016-01-01

    To provide a summary of the mechanisms that may cause dry eye after cataract surgery and discuss available and upcoming treatment modalities. Development or worsening of dry eye symptoms after cataract surgery is multifactorial with corneal nerve transection, inflammation, goblet cell loss, and meibomian gland dysfunction commonly cited as underlying disorders. With increasing awareness of the prevalence of dry eye disease, current surgical techniques are being analyzed for their contribution to the issue. Although many classic interventions, such as artificial tears and anti-inflammatory drops, remain first-line treatment options, they may not adequately address abnormalities of the tear film. The trend has been to create new drugs and technologies that target meibomian gland deficiencies and restore goblet cell numbers. Therapy for postoperative dry eye symptoms should be determined based on symptom severity and which underlying cause is most prominent at a given time. Patients with high-level risk factors for dry eye should be evaluated preoperatively to determine whether they have preexisting dry eye disease or if they are susceptible to developing disease after surgery.

    To assess the effect of dry eye disease on work productivity and performance of non-work-related activities, and patients' satisfaction with over-the-counter (OTC) dry eye treatments. In this prospective, noninterventional, cross-sectional study, conducted at 10 U.S. optometry/ophthalmology practices, 158 symptomatic dry eye patients naïve to prescription medication underwent standard dry eye diagnostic tests and completed Work Productivity and Activity Impairment (WPAI) and Ocular Surface Disease Index (OSDI) questionnaires. Use of OTC dry eye medication, and satisfaction with OTC medication and symptom relief were also assessed. On average, dry eye resulted in loss of 0.36% of work time (∼5 minutes over 7 days) and ∼30% impairment of workplace performance (presenteeism), work productivity, and non-job-related activities. Presenteeism and productivity impairment scores showed significant correlation with OSDI total (r = 0.55) and symptom domain (r = 0.50) scores, but not with dry eye clinical signs. Activity impairment score showed stronger correlation with OSDI total (r = 0.61) and symptom domain (r = 0.53) scores than with clinical signs (r ≤ 0.20). Almost 75% of patients used OTC dry eye medication. Levels of patient satisfaction with OTC medication (64.2%) and symptom relief from OTC (37.3%) were unaffected by administration frequency (≥3 vs. ≤2 times daily). Dry eye causes negligible absenteeism, but markedly reduces workplace and non-job-related performances. Impairment of work performance is more closely linked to dry eye symptoms than to clinical signs. Patients' perceptions of OTC dry eye medication tend to be more positive than their perceptions of symptom relief.

    Full Text Available Purpose: We have targeted primarily to show the variations of tear osmolarity during the daytime period in subjects with dry eyes and non-dry eyes and, secondarily, to evaluate the relationship of these variations with Schirmer’s test and break-up time (BUT. Material and Method: Twenty newly diagnosed dry eye patients and 20 healthy voluntary subjects with similar age and gender were included in this prospective study. In addition to the full ophthalmic examination, Schirmer’s test and BUT test were applied to all participants. Tear osmolarity measurements were done after pre-examination but in different day. The measurements were registered with TearLab Osmolarity System (TearLab Corporation, San Diego, CA, USA every 3 hours within 8:00 AM and 5:00 PM. The results were evaluated statistically. Results: No statistically significant difference was found between the mean age and gender of dry eye syndrome (DES and control groups (p>0.05. The mean measurements of Schirmer’s test and BUT in the DES group were statistically significantly lower than those in the control group (p=0.0001. The mean measurements of tear osmolarity at 8:00 AM, 11:00 AM, 2:00 PM, and 5:00 PM in the DES group were statistically significantly higher than those in the control group (p=0.001, p=0.0001. No statistically significant difference in tear osmolarity at 8:00 AM, 11: 00 AM, 2:00 PM, and 5:00 PM was found between the groups, and within DES and control groups (p>0.05. Discussion: We did not determine significant change in daytime variations of the tear osmolarity in dry eye patients and healthy subjects. As a secondary result, we can conclude that there is no difference among tear osmolarity, Shirmer’s and BUT tests in the diagnosis of DES. (Turk J Ophthalmol 2013; 43: 437-41

    The aim of this study was to investigate oral symptoms and clinical parameters in dry eye patients. Subjective reports of the sensation of a dry mouth, salivary flow rates, and clinical parameters of oral disease related to three different types of dry eye patients were examined. There were 224 individuals, including dry eye patients and control subjects. The dry eye patients were classified into three types: patients with Sjögren's syndrome (SS-DE), patients without SS-DE (non-SS-DE), and patients with Stevens-Johnson syndrome (SJS-DE). Salivary flow rates were measured using two kinds of sialometry. Subjective and objective oral symptoms and signs were also examined. Over half of the dry eye patients complained of a dry mouth. The flow rates of their stimulated whole saliva and parotid saliva were significantly lower than those of the control groups (P Candida frequently occurred in dry eye patients.

    Conclusions: In our study the Dry Eye Syndrome showed to have a high correlation with Diabetes Mellitus Tip II ( about 52.9%. Prevalence of Dry Eye was significantly higher at patients with longer duration of diabetes. Dry Eye seems to be an important contributing factor related to corneal abnormalities. Age and sex not seem to play any important role in this condition. Good glycemic control is important for prevention and control of Dry Eye Syndrome.

    Full Text Available Karl G Stonecipher,1 Jenny Chia,2 Ahunna Onyenwenyi,2 Linda Villanueva,2 David A Hollander2 1TLC Laser Eye Centers, Greensboro, NC, 2Allergan, Inc., Irvine, CA, USA Background: Dry eye is a multifactorial, symptomatic disease associated with ocular surface inflammation and tear film hyperosmolarity. This study was designed to assess patterns of topical cyclosporine ophthalmic emulsion 0.05% (Restasis® use in dry eye patients and determine if there were any differences in use based on whether dry eye is physician-coded as a primary or nonprimary diagnosis. Methods: Records for adult patients with a diagnosis of dry eye at an outpatient visit from January 1, 2008 to December 31, 2009 were selected from Truven Health MarketScan® Research Databases. The primary endpoint was percentage of patients with at least one primary versus no primary dry eye diagnosis who filled a topical cyclosporine prescription. Data analyzed included utilization of topical corticosteroids, oral tetracyclines, and punctal plugs. Results: The analysis included 576,416 patients, accounting for 875,692 dry eye outpatient visits: 74.7% were female, 64.2% were ages 40-69 years, and 84.4% had at least one primary dry eye diagnosis. During 2008–2009, 15.9% of dry eye patients with a primary diagnosis versus 6.5% with no primary diagnosis filled at least one cyclosporine prescription. For patients who filled at least one prescription, the mean months’ supply of cyclosporine filled over 12 months was 4.44. Overall, 33.9% of dry eye patients filled a prescription for topical cyclosporine, topical corticosteroid, or oral tetracycline over 2 years. Conclusion: Patients with a primary dry eye diagnosis were more likely to fill a topical cyclosporine prescription. Although inflammation is key to the pathophysiology of dry eye, most patients seeing a physician for dry eye may not receive anti-inflammatory therapies.

    To compare concentrations of tear cytokines in 3 groups composed of Sjögren syndrome (SS) dry eye, non-Sjögren syndrome (non-SS) dry eye, and normal subjects. Correlations between ocular surface parameters and tear cytokines were also investigated. Prospective cross-sectional study. SS dry eye patients (n = 24; 40 eyes) were diagnosed with primary SS according to the criteria set by the American-European Consensus Group. Non-SS dry eye patients (n = 25; 40 eyes) and normal subjects (n = 21; 35 eyes) were also enrolled. Tear concentrations of interleukin (IL)-17, IL-6, IL-10, IL-4, IL-2, interferon γ (IFN-γ), and tumor necrosis factor α (TNF-α) were measured by a multiplex immunobead assay. Ocular Surface Disease Index (OSDI), tear film breakup time (TBUT), Schirmer I test, and fluorescein staining scores were obtained from dry eye patients. All cytokine levels except for IL-2 were highest in the SS group, followed by non-SS dry eye group and control subjects. Concentrations of IL-17, TNF-α, and IL-6 were significantly different among the 3 groups (IL-17: SS > control P control P = .042, SS > non-SS P control P = .006, non-SS > control P = .034, SS > non-SS P = .029; IL-6: SS > control P = .002, non-SS > control P = .032, SS > non-SS P = .002). IL-17 was significantly correlated with TBUT (R = -0.22, P = .012) and Schirmer I test (R = -0.36, P = .027) scores in the SS group. IL-6 was significantly correlated only with TBUT (R = -0.38, P = .02) in the non-SS group. Differences in tear cytokine levels and correlation patterns between SS dry eye and non-SS dry eye patients suggest the involvement of different inflammatory processes as causes of dry eye syndrome.

    Primary Sjögren's syndrome (pSS) is an autoimmune disease, characterized by lymphocytic infiltration of exocrine glands and other organs, resulting in dry eye, dry mouth and extraglandular systemic findings. To explore the association of severe or very severe dry eye with extraocular involvement in patients diagnosed with primary Sjögren's syndrome. SJOGRENSER registry is a multicenter cross-sectional study of pSS patients. For the construction of our main variable, severe/very severe dry eye, we used those variables that represented a degree 3-4 of severity according to the 2007 Dry Eye Workshop classification. First, bivariate logistic regression models were used to identify the effect of each independent variable on severe/very severe dry eye. Secondly, multivariate analysis using regression model was used to establish the independent effect of patient characteristics. Four hundred and thirty-seven patients were included in SJOGRENSER registry; 94% of the patients complained of dry eye and 16% developed corneal ulcer. Schirmer's test was pathological in 92% of the patients; 378 patients presented severe/very severe dry eye. Inflammatory articular involvement was significantly more frequent in patients with severe/very severe dry eye than in those without severe/very severe dry eye (82.5 vs 69.5%, p = 0,028). Inflammatory joint involvement was associated with severe/very severe dry eye in the multivariate analysis, OR 2.079 (95% CI 1.096-3.941). Severe or very severe dry eye is associated with the presence of inflammatory joint involvement in patients with pSS. These results suggest that a directed anamnesis including systemic comorbidities, such as the presence of inflammatory joint involvement or dry mouth in patients with dry eye, would be useful to suspect a pSS.

    Psychiatric conditions and not just the treatments themselves might be involved in the pathophysiology of dry eye disease (DED). The aim of our study was to evaluate the association between depression and DED using objective and subjective tests in patients with newly diagnosed depressive disorder who were not using any medication which may help us to determine the sole effect of depression on dry eye. Thirty-six patients from the psychiatry clinic with a new diagnosis of depressive disorder and 32 controls were included in the study. All met the Diagnostic and Statistical Manual IV criteria for depression. Beck Depression Inventory (BDI) was used to measure depression severity and the State-Trait Anxiety Inventory (Stai1, Stai2) for concomitant anxiety symptoms. The Ocular Surface Disease Index (OSDI) and Visual Functioning Questionnaires (VFQ25) were completed and used to confirm diagnosis of DED in conjunction with the tear break up time (TBUT), ocular surface vital dye staining, and Schirmer's test. The comparison of depressive and control groups revealed significantly lower Schirmer (20.3 ± 9.9 vs. 25.7 ± 9.3 mm) and TBUT (7.8 ± 5.7 vs. 12.5 ± 7.8 s) scores with a consistently higher Oxford score (1.8 ± 3.2 vs. 0.2 ± 0.4) in the depressive group. Although the parameters were affected in the depressive group, this did not influence OSDI (86.1 ± 13.6 vs. 86.6 ± 13.3) and VFQ25 (30.8 ± 21.6 vs. 38.5 ± 29.1) scores. In both groups, the three psychological test scores (Stai1-2 and BDI) were correlated to each other but none of these tests were correlated to OSDI, VRQL, Schirmer, TBUT, and Oxford staining scores. Our study shows a definite association between depression and DED. We feel that it is important that psychiatrists take this into account especially while prescribing antidepressants which may aggravate dry eye signs.

We recruited 31 participants with SS dry eye, 30 participants with non-SS dry eye, and 35 healthy controls without dry eye symptoms. Noninvasive tear breakup time (NITBUT) and meibomian gland dropout score (meiboscore) were measured using the Oculus Keratograph 5 M. Meibomian gland expressibility and secretion quality were evaluated via slit lamp biomicroscopy. The correlation between measurements was analyzed. NITBUT was lower, and the meiboscore, meibomian gland expressibility, and secretion quality scores were significantly higher in the SS and non-SS groups than in the control group (p dry eye controls. SS patients had more severe meibomian gland dysfunction with poorer mean meiboscore and meibomian gland expressibility than non-SS patients.

    Full Text Available AIM: To compare the changes of wavefront aberrations in patients with diabetic retinopathy(DRand with different degrees of dry eye and to explore the reasons of visual quality decline in them. METHODS: We randomly selected 40 eyes in our hospital for treatment with DR and varying degrees of dry eye, and 40 eyes of normal control group. Topcon KR-1W visual quality analyzer was used to record the mean square the total high order corneal aberration, spherical aberration, comatic aberration and trefoil aberration of cornea with pupil diameters of 4mm and 6mm. Analysis of variance were used to compare the wavefront aberrations and the aberration values in the control group and in patients with diabetic retinopathy and with different degrees of dry eye. RESULTS: For 4mm and 6mm pupil diameters, nondiabetic retinopathy(NDRwith dry eye group, the nonproliferative diabetic retinopathy(NPDRwith dry eye group and proliferative diabetic retinopathy(PDRdry eye group had significantly increased tHOA, coma and trefoil compared with the contrast group(PPCONCLUSION: Dry eye of diabetic retinopathy with different degrees is closely related to the increase of wavefront aberration. Increased wavefront aberration may be one of the reasons to reduced visual quality in patients with diabetic retinopathy and with dry eye, and provide the basis for the decline of visual function of diabetic patients with dry eye.

    To evaluate preoperative and postoperative dry eye and the effect of cyclosporine A treatment in patients screened for corneal refractive surgery and treated with photorefractive keratectomy (PRK) or LASIK. A consecutive case series of 1,056 patients screened for corneal refractive surgery from 2007 to 2012 was retrospectively analyzed. The level of preoperative and postoperative dry eye and the responsiveness to topical cyclosporine A treatment were assessed. One eye of each patient was randomly selected. A total of 642 eyes progressed to surgery: 524 (81.6%) and 118 (18.4%) underwent LASIK and PRK, respectively. Of 81 (7.7%) diagnosed as having dry eye, 55 were deemed potential candidates and optimized for refractive surgery. Thirty-seven patients with moderate dry eye were treated with topical cyclosporine A prior to surgery (mean duration: 3.2 ± 2.1 months; range: 1 to 12 months). After cyclosporine A treatment, 28 (75.7%) eyes underwent LASIK, 4 (10.8%) eyes underwent PRK, and 5 (13.5%) eyes were not operated on due to failed treatment of dry eye. Postoperative refractive surgery-induced neurotrophic epitheliopathy (LINE in LASIK) was noted in 132 (27.3%) and 12 (11.1%) eyes that underwent LASIK and PRK, respectively. Topical cyclosporine A was prescribed in 79 LASIK-induced and 3 PRK-induced dry eyes. After 12 months or more of cyclosporine A treatment, 5 (6.1%) eyes continued to have dry eye symptoms or signs.

    To assess the clinical characteristics and changes in ocular surface cytology of dry eye in patients with systemic autoimmune disease. The case-control study was conducted in the Second Hospital of Tianjin Medical University, Tianjin, China, from February 2016 to January 2017, and comprised systemic autoimmune disease patients and healthy controls. Schirmer's I test, tear breakup time test, and fluorescein staining were performed on all subjects. Both groups were evaluated for dry eye with the current diagnostic criteria. Conjunctival impression cytology and the morphology of epithelial cells were observed in both groups of subjects. Flow cytometry was used to identify the amount of apoptosis. SPSS 15 was used to analyse the data. Each of the two groups had 60(50%) subjects each. The morbidity of dry eye in the control group was 17(28.3%), while it was 31(51.7%) in the patients (pdry eye, the severity level of cells obtained by conjunctival impression sampling was significantly higher in patients than in controls (pdry eye than in patients without dry eye in each group, and among patients with dry eye, the percentage of conjunctival epithelial cells undergoing apoptosis was higher in the patients than in controls (pdry eye in systemic autoimmune disease than in subjects with dry eye in healthy controls.

    Full Text Available Abstract Background This study was performed to assess the prevalence of dry eye syndrome and diabetic retinopathy (DR in type 2 diabetic patients and their contributing factors. Methods 199 type 2 diabetic patients referred to Yazd Diabetes Research Center were consecutively selected. All Subjects were assessed by questionnaire about other diseases and drugs. Dry eye syndrome was assessed with Tear break up time tests and Schirmer. All the subjects underwent indirect ophthalmoscopy and retinal color photography. DR was graded according to early Treatment Diabetic Retinopathy (ETDRS criteria. Results Of 199 subjects, 108 patients (54.3% suffer from dry eye syndrome. Although dry eye syndrome was more common in older and female patients, this association was not significant. But there was significantly association between dry eye syndrome and duration of diabetes (P = 0.01. Dry eye syndrome was more frequent in diabetic patients with DR (P = 0.02. DR was found in 140 patients (70.35%, which included 34 patients (17.1% with mild non proliferative DR (NPDR, 34 patients (17.1% with moderate NPDR, 22 patients (11.1% with severe NPDR and 25 patients (25.1% with proliferative DR (PDR. There were significant relation between age, sex and duration of diabetes and DR. Conclusion In this study the prevalence of dry eye syndrome was 54.3%. Diabetes and dry eyes appear to have a common association. Further studies need to be undertaken to establish an etiologic relationship. However, examination for dry eye should be an integral part of the assessment of diabetic eye disease.

    Laser-assisted in situ keratomileusis (LASIK) is a frequently performed corneal refractive surgery with excellent refractive outcomes. The most common complication of LASIK is dry eyes, with virtually all patients developing some degree of dryness in the immediate postoperative period. Identifying preoperative dry eyes, and conscientious attention and treatment in the perioperative time period, can lead to enhanced patient satisfaction and more accurate visual outcomes. Improved understanding of the development of dry eyes after LASIK will advance our understanding of the complex pathophysiology of dry eye disease. PMID:22174730

    To analyze the distribution of tear film osmolarity in patients with dry eye and its association with other ocular surface parameters. Tear osmolarity and other quantitative dry eye parameters were obtained from patients with 1) clinically significant dry eye (significant symptoms and ocular surface staining, n = 131), 2) symptoms-only dry eye (significant symptoms but no significant ocular surface staining, n = 52), and 3) controls (no significant symptoms or staining, n = 42). Tear osmolarity varied significantly across groups (P = 0.01), with patients with clinically significant dry eye having the highest tear osmolarity (312.0 ± 16.9 mOsm/L), control patients having the lowest tear osmolarity (305.6 ± 9.7 mOsm/L), and patients with symptoms-only dry eye falling in between (307.4 ± 5.6 mOsm/L). Patients with clinically significant dry eye also tended to have a greater intereye difference in osmolarity (12.0 ± 13.4) than did the individuals with symptoms-only dry eye (9.1 ± 12.4) and controls (9.0 ± 7.4) (P = 0.06). In multivariable regression models, higher tear osmolarity was associated with higher Ocular Surface Disease Index, discomfort subscore (P = 0.02), and higher corneal and conjunctival staining scores (P eye tear osmolarity was not correlated with the corresponding tear film breakup time or Schirmer test (P > 0.05 for both). Individuals with symptomatic dry eye that is not yet clinically significant seem to have higher and more variable osmolarity measurements than controls, potentially indicating that changes in osmolarity precede clinical findings.

    Thyroid orbitopathy (TO) is an autoimmune disease that is complicated by ocular surface disorders, leading to discomfort. Dry eye is very prevalent in patients with TO. Recent studies on the pathogenesis of dry eye have focused on the inflammatory process, and some supporting evidence has been discovered. Because TO is a disorder of autoimmune origin, we assumed that the association between TO and dry eye is related to inflammation. Inflammation of the ocular surface in TO-related dry eye has not been well studied. In this study, we assessed cellular inflammation of the ocular surface and the cytokine profiles in patients with TO-related dry eye. Conjunctival impression cytology (CIC) was assessed with an immunofluorescent assay. TO-related dry eye was diagnosed by using the Schirmer test, tear break-up time, thyroid function, and clinical signs. CIC was combined with immunological staining of interleukin-1a (IL-1a), IL-1b, and IL- 6. The immunological impression cytology (IC) grade was compared to the clinical activity score of TO. All TO patients with dry eye were positive for IL-1a, IL-1b, and IL-6. However, the normal controls were also positive for IL-1a. A trend was observed between the clinical inflammatory score and immunological IC grade. This study was the first to delineate the immunological IC of TO-related dry eye. Our study aimed to investigate the pathogenesis of dry eye in TO. Our findings suggest that the conjunctival cytokines IL-1a, IL-1b, and IL-6 may play a role. The results of this study will be useful for future studies of additional inflammatory cytokines, and the levels of these cytokines could be used as an outcome to assess the efficacy of treatment, such as anti-cytokine or immunosuppression therapy, in patients with TO-related dry eye or other ocular surface inflammatory disorders.

    To assess the impact of autologous serum (AS) eye drops on the ocular surface of patients with bilateral severe dry eye and to draw a comparison between the clinical and laboratory examinations and the degree of subjective symptoms before and after serum treatment. A three-month prospective study was conducted on 17 patients with severe dry eye. AS eye drops were applied a maximum of 12 times a day together with regular therapy. Dry eye status was evaluated by clinical examination (visual acuity, Schirmer test, tear film breakup time, vital staining, tear film debris and meniscus), conjunctival impression cytology (epithelial and goblet cell density, snake-like chromatin, HLA-DR-positive and apoptotic cells) and subjectively by the patients. The application of AS eye drops led to a significant improvement in the Schirmer test (p treatment. A significant decrease (p eyes. We found that three-month AS treatment led especially to the improvement of ocular surface dryness and damage of the epithelium. The improvement of dry eye after AS treatment correlated well with the clinical, laboratory and subjective findings. From the patients' subjective point of view, the positive effect of AS decreased with time, but still persisted up to three months after the end of therapy.

    Dry eye is a common problem in Ophthalmology and may occur for many reasons including Sjogren's syndrome (SS). Recent studies have identified autoantibodies, anti-salivary gland protein 1 (SP1), anti-carbonic anhydrase 6 (CA6) and anti-parotid secretory protein (PSP), which occur early in the course of SS. The current studies were designed to evaluate how many patients with idiopathic dry eye and no evidence of systemic diseases from a dry eye practice have these autoantibodies. Patients from a dry eye clinic and normal controls were assessed by Schirmer's test for tear flow. Sera were assessed for autoantibodies using ELISA assays. Statistics was performed with Prism 7 software and student's unpaired t test. In this study 60% of the dry eye patients expressed one of these autoantibodies. Only 30% expressed one of the autoantibodies associated with long-standing SS, which are included in the diagnostic criteria for SS, anti-Ro and anti-La. Patients with disease for less than 2 years and mild dry eyes did not express anti-Ro or anti-La, while 25% expressed anti-SP1. Similar observations, with smaller numbers, were made when patients had not only dry eye but also dry mouth. Antibodies to SP1, CA6 and PSP occur in some patients with idiopathic dry eyes. Further studies will be needed to determine how many of these patients go on to develop systemic manifestations of SS. Testing for these autoantibodies may allow early recognition of patients with SS. This will lead to improved management of the patients and the development of new strategies to maintain normal lacrimal and salivary gland function in patients with SS.

    To evaluate ocular forward light scattering and corneal backward light scattering in patients with dry eye. Thirty-five eyes in 35 patients with dry eye and 20 eyes of 20 healthy control subjects were enrolled. The 35 dry eyes were classified into two groups according to whether superficial punctate keratopathy in the central 6-mm corneal zone (cSPK) was present or not. Ocular forward light scattering was quantified with a straylight meter. Corneal backward light scattering from the anterior, middle, and posterior corneal parts was assessed with a corneal densitometry program using the Scheimpflug imaging system. Both dry eye groups had significantly higher intraocular forward light scattering than the control group (both Pdry eye group with cSPK had significantly higher values in anterior and total corneal backward light scattering than the other two groups. Moderate positive correlations were observed between the cSPK score and corneal backward light scattering from the anterior cornea (R=0.60, Pdry eyes than in normal eyes. Increased corneal backward light scattering in dry eye at least partially results from cSPK overlying the optical zone. Copyright 2014 The Association for Research in Vision and Ophthalmology, Inc.

    Objective The purpose of this study was to examine the severity and quality of ocular pain complaints in patients with dry eye symptoms. Methods Subjects with clinically-relevant dry eye symptoms (dryness, discomfort, tearing) of unknown origin seen in the Miami Veterans Affairs eye clinic were administered questionnaires for dry eye symptoms and ocular pain and underwent a standardized ocular examination. Qualities and severity ratings of ocular pain in subjects with idiopathic dry eye were compared to similar measures from published data in other chronic pain populations. Results The study sample consisted of 154 subjects, of which 91% were male and ranged in age from 27 to 89 (mean age = 61). Fifty-three percent of participants reported an average ocular pain of at least moderate intensity (numerical rating scale (NRS) ≥ 4), with specific characteristics (i.e., “burning” spontaneous pain) reported at frequencies comparable to prevalent chronic neuropathic pain syndromes as reported in the literature. Significant correlations were found between ocular pain metrics and dry eye symptom severity scores (r=0.57 to 0.66). Dry eye signs, however, did not generally correlate with ocular pain severity. Conclusions A significant proportion of subjects with idiopathic dry eye symptoms reported moderate or greater ocular pain intensity, with the majority endorsing descriptors commonly used by patients with non-ocular neuropathic pain conditions. Identifying sub-groups of dry eye patients based on the presence and characteristics of ocular pain complaints may improve dry eye sub classification and better individualize treatment strategies.

    To investigate the short- and long-term effects of diquafosol ophthalmic solution on the optical quality of the eyes in patients with aqueous-deficient dry eye. Sixteen eyes in 16 patients with mild or moderate aqueous-deficient dry eye were treated with 3% diquafosol ophthalmic solution. Ocular higher-order aberrations (HOAs) were measured with a wavefront sensor before and at 15 min after diquafosol instillation at the baseline visit and at 4 weeks after treatment initiation. Dry eye symptoms, tear break-up time (BUT), corneal/conjunctival fluorescein staining and Schirmer's test were also evaluated before and after treatment with diquafosol. Treatment with diquafosol ophthalmic solution significantly improved dry eye symptoms, corneal staining and BUT. Compared with mean total HOAs at baseline (0.180 ± 0.06 μm), those at 4 weeks after treatment significantly decreased (0.148 ± 0.039 μm; p = 0.035), whereas those 15 min after diquafosol instillation at the baseline visit did not change significantly (0.170 ± 0.049 μm; p = 0.279). Although no significant change in HOAs was observed as a short-term effect of a single-drop instillation of diquafosol, long-term use of diquafosol to treat aqueous-deficient dry eye reduced HOAs as well as improved corneal epithelial damage and tear film stability. © 2014 Acta Ophthalmologica Scandinavica Foundation.

    To evaluate the presence of dry eye and primary Sjögren syndrome (SS) in patients with migraine. In total, 46 eyes of 46 patients with migraine (group 1) and 50 eyes of 50 healthy subjects (group 2) were included in this study. Detailed ophthalmologic, neurologic and rheumatologic examination were performed on all participants. Ocular surface disease index questionnaire, tear function tests, visual analog scale for pain, serologic analysis were also performed. Dry eye symptoms and findings were significantly higher and more severe in group 1 when compared with group 2. Primary SS was not found in any of the participants. The migraine lifetime duration was negatively correlated with the tear function tests while it was positively correlated with the ocular surface disease index scores. Dry eye symptoms and findings are higher in migraine patients when compared with the healthy subjects without the presence of Sjögren syndrome.

  10. Inflammation in dry eye.

    Stern, Michael E; Pflugfelder, Stephen C

    2004-04-01

    Dry eye is a condition of altered tear composition that results from a diseased or dysfunctional lacrimal functional unit. Evidence suggests that inflammation causes structural alterations and/or functional paralysis of the tear-secreting glands. Changes in tear composition resulting from lacrimal dysfunction, increased evaporation and/or poor clearance have pro-inflammatory effects on the ocular surface. This inflammation is responsible in part for the irritation symptoms, ocular surface epithelial disease, and altered corneal epithelial barrier function in dry eye. Anti-inflammatory therapies for dry eye target one or more of the inflammatory mediators/pathways that have been identified in dry eye.

    to determine the frequency and severity of dry eye syndrome (DES) in primary open-angle glaucoma (POAG) patients that are newly diagnosed or already receiving beta blocker instillation therapy. A total of 127 patients (190 eyes) with POAG were divided into two groups. Group 1 included 55 newly diagnosed patients (88 eyes), group 2-72 POAG patients (102 eyes) instilling timolol 0.5% twice daily into the affected eye. The control group included 20 patients (40 eyes) aged 60-88 years (73.6 ± 9.2 years on average) with early age-related cataract. DES was found in 69 POAG patients (79%) who was just starting their topical hypotensive therapy and 85 of those (84%) under treatment (p = 0.39). One should take into account when prescribing ocular hypotensive therapy that newly diagnosed POAG patients usually already suffer from a dry eye. The use of topical beta blockers that contain preservatives exacerbates dry eye signs and symptoms in these patients.

    Accurate diagnosis and early recognition of dry eye symptoms are important in the management of dry eye disease (DED). This study aimed to evaluate concordance between patient and clinician assessment of DED severity and treatment response. This cross-sectional study was conducted in 2 ophthalmology clinics in Taiwan. Clinicians assessed severity based on the Dry Eye Workshop severity grading (levels 1-4; where 4 = most severe), whereas patients completed the Ocular Surface Disease Index questionnaire. To evaluate the treatment response, patients completed the Subject Global Assessment scale, and clinicians independently assessed patients using the Clinical Global Impression scale. A total of 466 patients were included. Clinicians graded 88.3% of patients as level 1/2, 9.0% as level 3, and 2.7% as level 4 Dry Eye Workshop severity, whereas 44.9% of patients reported normal/mild symptoms, 17.1% with moderate severity, and 38.0% with severe DED. Patients were primarily treated with artificial tears. The clinician assessed 10.3% of patients as unchanged on disease severity after treatment and 88.0% as improved, whereas 49.2% of patients reported dry eye symptoms being almost the same after treatment and 34.6% reported improved symptoms. There was low agreement between clinician and patient assessments in terms of disease severity (rho = 0.17, P treatment response (rho = 0.22, P treatment response between patient and clinician assessment. Clinicians may underestimate DED severity and persistence of dry eye symptoms after treatment with artificial tears.Clinical Trial Registration-URL: http://www.clinicaltrials.gov.

    Purpose To determine whether proinflammatory cytokine genes were potential susceptibility candidate genes for Korean patients with non-Sjogren dry eye, we investigated the association of the interleukin 1 beta (IL1B), interleukin 6 (IL6), and interleukin 6 receptor (IL6R) variations with this disease in Korean patients. Methods Genomic DNA was extracted from blood samples of unrelated non-Sjogren dry eye patients and healthy control individuals who visited the Eye Center and Health Promotion Center of St. Mary’s Hospital in Seoul, Korea. For screening genetic variations in proinflammatory cytokine genes, the 511 (rs16944) and 31 (rs1143627) positions in the promoter region of IL1B, rs1143634 in exon 5 of IL1B, rs1800795 of the IL6 promoter, and Asp358Ala (rs8192284) of IL6R were genotyped using the polymerase chain reaction, restriction fragment length polymorphisms, and direct sequencing. Results Among the polymorphisms, rs1143634 (F105F) in exon 5 of IL1B was significantly different between the patient and control groups. The frequency of the C/T genotype in dry eye patients was decreased relative to that of the control subjects (10.4% versus 3.9%, p=0.043, OR=3.337). For the IL6R gene, the genotypic and allelic distribution of rs8192284 was different between the dry eye patients and the controls: CC genotype (p=0.017, OR=2.12) and C allele (OR=1.26). Conclusions This is the first report of genetic variation screening of proinflammatory cytokine genes in Korean non-Sjogren dry eye patients. It is suggested that rs1143634 of IL1B and rs8192284 of IL6R act as susceptibility variations in Korean non-Sjogren dry eye patients. PMID:22128229

    To investigate the value of 3 novel autoantibodies [salivary protein 1 (SP1), carbonic anhydrase 6 (CA6), and parotid secretory protein (PSP)] in differentiating Sjögren's syndrome (SS)-related dry eye from non-SS dry eye. Forty-six dry eye patients with SS (SS dry eye), 14 dry eye patients without SS (non-SS dry eye), and 25 controls were included. The 2012 American College of Rheumatology classification criteria were used for the diagnosis of SS. After a detailed review of systems, the Ocular Surface Disease Index questionnaire, Schirmer test without anesthesia, tear film breakup time, and ocular surface staining were performed to assess dry eye. All participants underwent serological testing using a commercially available finger prick kit. Thirty-seven patients with SS (80.4%) had a positive traditional autoantibody and 28 (60.9%) had a positive novel autoantibody. Traditional autoantibodies were absent in all non-SS dry eye patients and controls. Novel autoantibodies were present in 7/14 (50%) non-SS dry eye patients and 4/25 (16%) controls. Among 3 novel autoantibodies, anti-CA6 was significantly more prevalent in the SS and non-SS dry eye groups than in controls (52.2% vs. 42.9% vs. 8.0%, P = 0.001). Dry eye patients with positive anti-CA6 alone were significantly younger than patients with only traditional autoantibodies. Anti-CA6 was associated with worse dry eye signs and symptoms. Anti-CA6 was the most prevalent novel autoantibody in patients with dry eye, and was associated with younger age and more severe disease. Longitudinal studies are needed to determine whether anti-CA6 is a marker for early SS or perhaps another form of an autoimmune dry eye disease.

    To evaluate the clinical outcomes of thermal pulsation treatment in patients with meibomian gland dysfunction (MGD) and dry eye secondary to Sjogren disease. Twenty-four eyes from 13 patients with previously diagnosed Sjogren disease who presented to our institution with dry eye symptoms and had thermal pulsation treatment were prospectively followed up. Patients underwent comprehensive slit-lamp examination, including MGD grading, gland oil flow, corneal and conjunctival staining scores, and tear break-up time (TBUT). Tear osmolarity was tested before and after treatment. The average patient age was 62.4 years (range, 31-78 yrs); 12 were women and 1 a man. The average meibomian gland oil flow score showed an increase from pretreatment 0.71 to 1.75 at 1 year posttreatment (range 9-15 months) (P = 0.001). The average corneal staining score decreased from a pretreatment grade of 1.04 to a posttreatment grade of 0.36 (P dry eye disease in patients with Sjogren disease and should not be overlooked when considering treatment options. Thermal pulsation is a therapeutic option for patients with Sjogren disease who have MGD and dry eye symptoms. After a single treatment, patients exhibited increased oil flow and tear break-up time with an associated decrease in corneal and conjunctival staining.

    Rheumatoid arthritis has manifestations in various organs including ophthalmic involvement. The present study evaluates prevalence of dry eye and secondary Sjogren's syndrome using salivary scintigraphy which has not been used in previous reports. To evaluate the prevalence of secondary Sjogren's syndrome in patients with rheumatoid arthritis, including clinical characteristics and dry eye, compared with non-Sjogren's syndrome. Descriptive cross sectional study Sixty-one patients with rheumatoid arthritis were recruited at Siriraj Hospital during March 2009-September 2010 and filled in the questionnaires about dry eye for Ocular Surface Disease Index (OSDI) with a history taking of associated diseases, medications, duration of symptoms of dry eyes and dry mouth. The Schirmer I test without anesthesia, tear break-up time, rose bengal staining score, severity of keratitis and salivary scintigraphy were measured and analyzed. Prevalence of secondary Sjogren's syndrome and dry eye were 22.2% (95% CI 15.4 to 30.9) and 46.7% (95% CI 38.0 to 55.6), respectively. Dry eye interpreted from OSDI, Schirmer 1 test, tear break-up time and rose bengal staining was 16.4%, 46.7%, 82% and 3.3% respectively. Fifty-two percent of patients had a history of dry eye and dry mouth with mean duration 27.4 and 29.8 months, respectively. Superficial punctate keratitis and abnormal salivary scintigraphy were found in 58.2% and 77.8%. Duration of rheumatoid arthritis, erythrocyte sedimentation rate were not correlated with secondary Sjogren's syndrome. Dry eye from OSDI with secondary Sjogren's syndrome (33.3%) compared with non-Sjogren's syndrome (9.5%) was significant difference (p = 0.008). Adjusted odds ratio for secondary Sjogren's syndrome in OSDIL score > 25 was 13.8 (95% CI 2.6 to 73.8, p = 0.002) compared to OSDI score dry eye syndrome and secondary Sjogren's syndrome in rheumatoid arthritis was crucial for evaluation of their severity and proper management.

    To investigate the expression, release, and proteolytic degradation of galectin-3 in patients with dry eye disease. Observational case series with a comparison group. Tear washes and conjunctival impression cytology specimens were collected through standard procedures from 16 patients with dry eye and 11 age-matched healthy subjects. Galectin-3 content in tears was analyzed by quantitative Western blot, using recombinant galectin-3 protein to generate a calibration curve. The relative expression of galectin-3 and matrix metalloproteinase 9 (MMP9) was evaluated by quantitative polymerase chain reaction. The cleavage of galectin-3 was studied in vitro using activated recombinant MMP9 and protease inhibitors. The concentration of galectin-3 protein in tears, but not galectin-3 expression in conjunctival epithelium, was significantly higher in tears of patients with dry eye (0.38 ng/μg total protein, range 0.04-1.36) compared to healthy subjects (0.12 ng/μg total protein, range 0.00-0.41) (P tear samples from healthy subjects, whereas 50% of the dry eye samples were characterized by the additional presence of a partially degraded form (∼25.4 kDa). In our experiments, elevated expression of MMP9 in dry eye subjects correlated with the ability of active MMP9 to cleave galectin-3 from recombinant origin. Interestingly, cleavage of endogenous galectin-3 in tear samples was impaired using a broad-spectrum proteinase inhibitor cocktail, but not the pan-specific MMP inhibitor GM6001, suggesting the presence of proteases other than MMPs in promoting galectin-3 degradation in dry eye. Our results indicate that release of cellular galectin-3 into tears is associated with epithelial dysfunction in dry eye, and that galectin-3 proteolytic cleavage may contribute to impaired ocular surface barrier function.

    Full Text Available Purpose. To evaluate the tear function tests in patients with Hashimoto’s thyroiditis and to compare the results with healthy subjects. Methods. A hundred and ten patients with Hashimoto’s thyroiditis and 100 healthy subjects were included in this study. The presence of thyroid-associated ophthalmopathy and tear function tests were evaluated clinically. The results were first compared between the patients and the control groups and then compared between patients with NOSPECS and patients without NOSPECS. Logistic regression analyses of the risk factors for dry eye including sex, gender, free plasma thyroxine, proptosis, upper eyelid margin-reflex distance, and duration of the disease were also evaluated. Results. The mean ocular surface disease index score was significantly higher and mean Schirmer and mean tear break-up time scores were significantly lower in patients compared to control subjects. Mean Schirmer and tear break-up time scores were found to be significantly lower in patients with NOSPECS when compared to the patients without NOSPECS. Both proptosis and free plasma thyroxine levels were significantly associated with dry eye. Conclusions. Patients with Hashimoto’s thyroiditis tend to develop dry eye more common than healthy subjects. Proptosis and lower free plasma thyroxine levels were found to be risk factors for the presence of dry eye.

    Full Text Available Purpose. To investigate corneal biomechanical properties in patients with dry eye and in healthy subjects using Corneal Visualization Scheimpflug Technology (CorVis ST. Methods. Biomechanical parameters were measured using CorVis ST in 28 eyes of 28 patients with dry eye (dry eye group and 26 normal subjects (control group. The Schirmer I test value, tear film break-up time (TBUT, and corneal staining score (CSS were recorded for each eye. Biomechanical properties were compared between the two groups and bivariate correlation analysis was used to assess the relationship between biomechanical parameters and dry eye signs. Results. Only one of the ten biomechanical parameters was significantly different between the two groups. Patients in the dry eye group had significantly lower highest concavity time (HC-time (P=0.02 than the control group. Correlation analysis showed a significant negative correlation between HC-time and CSS with marginal P value (ρ=-0.39, P=0.04 in the dry eye group. Conclusions. The corneal biomechanical parameter of HC-time is reduced in dry eyes compared to normal eyes. There was also a very weak but significant negative correlation between HC-time and CSS in the dry eye group, indicating that ocular surface damage can give rise to a more compliant cornea in dry eyes.

    To examine the effect of general contact lens and material characteristics, care solutions, treatment, and patient-related factors on contact lens-related dry eye. The data were derived from the Contact Lens and Dry Eye Study, designed as a cross-sectional and nested case-control study including 360 subjects. In separate statistical models, logistic regression was used to examine general contact lens characteristics, specific hydrogel lens materials, care solutions, and patient-related factors associated with dry eye status (controlled for age, gender, and current treatments). Several factors were significantly associated with dry eye, including treatment factors such as a recent contact lens refitting (odds ratios [OR] = 5.75, 95% confidence intervals [CI] = 2.14 to 15.46) and use of artificial tears/rewetting drops (OR = 1.09, 95% CI = 1.02 to 1.16), in addition, currently worn materials including Food and Drug Administration (FDA) group II (OR = 2.98, 95% CI = 1.14 to 6.19) and IV (OR = 1.87, 95% CI = 1.08 to 3.24). Significant patient-related factors included decreased overall satisfaction (OR = 3.57, 95% CI = 2.08 to 5.88,), dry eye in the absence of contact lens wear (OR = 6.54, 95% CI = 2.57 to 16.62), reduced daily lens wear duration (OR = 1.16, 95% CI = 1.06 to 1.26), and reduced ability to wear lenses as long as desired (OR = 2.44, 95% CI = 1.30 to 4.54). Care solutions were not associated with contact lens-related dry eye. The strong association of common treatment factors with dry eye status in contact lens wearers suggests that these treatments are not entirely effective. The use of high water content materials was strongly related to dry eye in lens wearers, whereas care solutions were not. Contact lens-related dry eye was also associated with several patient-related factors such as greater ocular discomfort (without lenses), dissatisfaction, and inability to wear lenses for desired durations.

  10. Making the diagnosis of Sjögren’s syndrome in patients with dry eye

    Science.gov (United States)

    Beckman, Kenneth A; Luchs, Jodi; Milner, Mark S

    2016-01-01

    Sjögren’s syndrome (SS) is a chronic and progressive systemic autoimmune disease that often presents initially with symptoms of dry eye and dry mouth. Symptoms are often nonspecific and develop gradually, making diagnosis difficult. Patients with dry eye complaints warrant a step-wise evaluation for possible SS. Initial evaluation requires establishment of a dry eye diagnosis using a combination of patient questionnaires and objective ocular tests, including inflammatory biomarker testing. Additional work-up using the Schirmer test and tear film break-up time can differentiate between aqueous-deficient dry eye (ADDE) and evaporative dry eye. The presence of ADDE should trigger further work-up to differentiate between SS-ADDE and non-SS-ADDE. There are numerous non-ocular manifestations of SS, and monitoring for SS-related comorbid findings can aid in diagnosis, ideally in collaboration with a rheumatologist. The clinical work-up of SS can involve a variety of tests, including tear function tests, serological tests for autoantibody biomarkers, minor salivary gland and lacrimal gland biopsies. Examination of classic SS biomarkers (SS-A/Ro, SS-B/La, antinuclear antibody, and rheumatoid factor) is a convenient and non-invasive way of evaluating patients for the presence of SS, even years prior to confirmed diagnosis, although not all SS patients will test positive, particularly those with early disease. Recently, newer biomarkers have been identified, including autoantibodies to salivary gland protein-1, parotid secretory protein, and carbonic anhydrase VI, and may allow for earlier diagnosis of SS. A diagnostic test kit is commercially available (Sjö®), incorporating these new biomarkers along with the classic autoantibodies. This advanced test has been shown to identify SS patients who previously tested negative against traditional biomarkers only. All patients with clinically significant ADDE should be considered for serological assessment for SS, given the

    To evaluate conjunctival impression cytology and HLADR expression changes after wearing scleral contact lenses (ScCLs) for moderate to severe dry eye disease (DED). Prospective interventional case series. Forty-one eyes from 25 patients with moderate to severe DED were evaluated for Esclera ScCL treatment. Best-corrected visual acuity (BCVA) and slit-lamp findings were assessed. Impression cytology specimens were obtained from DED patients at the baseline and after wearing ScCLs for 12 months. The impression cytology specimens were analyzed using morphological results score, and HLA-DR positive cells were detected and quantified. The values were compared to assess the IC changes after wearing ScCLs. Forty-one eyes from 25 patients were fitted with ScCLs to manage DED. The underlying diseases were Stevens-Johnson syndrome (22 eyes), Sjogren's syndrome (11 eyes), graft-versus-host disease (2 eyes), dry eye after keratomileusis (2 eyes) and undifferentiated ocular surface disease (4 eyes). The HE-PAS impression cytology score did not differ significantly before and after wearing ScCLs for 12 months in DED patients (p>0.05). The percentage of eyes expressing the HLA-DR antigen in the temporal conjunctiva after wearing ScCL for 12 months significantly increased in patients with Sjogren's syndrome (11.11% to 66.66%; p=0.0498). In groups with Stevens Johnson syndrome and other ocular surface disorders, we did not observe statistically significant differences (p>0.05). The ScCLs did not change the parameters used to evaluate inflammatory processes, which were measured using conjunctival impression cytology and HLA-DR expression, except in Sjogren syndrome, in which there was an unexpected increase in HLA expression.

    2015-01-01

    The aim of this study is to evaluate the efficacy and safety of oral pilocarpine in treating severe dry eye unresponsive to conventional conservative treatment in patients with Sjögren syndrome. A prospective study. Oral doses of pilocarpine were administered for at least 3 months to patients with Sjögren syndrome complicated by established dry eye of great severity unresponsive to conventional conservative treatment. Subjective eye symptoms (dry eye sensation and eye pain), fluorescein staining scores, rose Bengal staining scores, and tear film breakup time measurements improved significantly after 1 month and 3 months of oral treatment with pilocarpine, whereas no significant improvement was noted in Schirmer I testing. Oral administration of pilocarpine was useful in treating severe dry eye unresponsive to conventional conservative treatment in patients with Sjögren syndrome from the standpoint of efficacy and safety. Thus, we conclude that oral pilocarpine is effective as a new option in treating severe dry eye.

The multiple Logistic regression was used to analyze the risk factors for dry eye in patients with T2DM. RESULTS: There was no significant differences between the patients with different diabetic duration, on BUT, SⅠt, winking frequency, vision, FL and the scores of dry eye symptoms(P>0.05. HbA1c was significantly correlated with FL(P0.05. There were significant differences in FL among patients with HbA1c in 8.1% to 11.8%(P0.01. FBG was significantly correlated with FL and winking frequency(P0.05. The 2h PBG was significantly correlated with tear secretion and vision(P0.05. Plasma C-peptide was significantly correlated with BUT(PP0.05. FBG and plasma C-peptide in T2DM patients were risk factors for occurrence of dry eye(P0.05. CONCLUSION: Poor function of insulin secretion and poor control of blood glucose in T2DM patients are risk factors for dry eye. Both of them can decline tear film stability. High blood glucose levels easily lead to decrease of tear secretion, vision and corneal epithelial defect.

    Review of the etiology, clinical manifestations, and treatment of dry eye disease (DED). Articles indexed in PubMed (National Library of Medicine), Iowa Drug Information Service (IDIS), and the Cochrane Reviews and Trials in the last 10 years using the key words "dry eye disease," "dry eye syndrome," "dry eye and treatment." Primary sources were used to locate additional resources. Sixty-eight publications were reviewed, and criteria supporting the primary objective were used to identify useful resources. The literature included practice guidelines, book chapters, review articles, original research articles, and product prescribing information for the etiology, clinical manifestations, diagnosis, and treatment of DED. DED is one of the most common ophthalmic disorders. Signs and symptoms of DED vary by patient, but may include ocular irritation, redness, itching, photosensitivity, visual blurring, mucous discharge, and decreased tear meniscus or break-up time. Symptoms improve with treatment, but the condition is not completely curable. Treatment includes reducing environmental causes, discontinuing medications that cause or worsen dry eye, and managing contributing ocular or systemic conditions. Most patients use nonprescription tear substitutes, and if these are not sufficient, other treatment is prescribed. These treatments include the ophthalmic anti-inflammatory agent cyclosporine, punctal occlusion, eye side shields, systemic cholinergic agents, and autologous serum tears. This article reviews the etiology, symptoms, and current therapy for DED.

We investigated 21 patients (42 eyes; 18 women, 3 men; mean age, 63.19±13.33 years) with dry eye syndrome. Additionally, for the sake of comparison, 12 normal subjects of the same age group (24 eyes; 10 women, 2 men; mean age, 68.25±2.63 years) were included. Lacrimal scintigraphy, Schirmer-1 test, break-up time (BUT), and rose bengal ocular surface vital staining were performed in these cases. According to the results of lacrimal scintigraphy, the mean value of T1/2 was 4.16±1.22 minutes and the mean value of radioisotope (RI) was 14.15%±2.30% in normal subjects. However, in patients with dry eye syndrome, these values were 20.59±1.97 minutes and 55.64%±6.90%, respectively. Consistent with the results of ophthalmologic tests, the mean Schirmer-1 value was 12.46±2.10 mm, the mean value of BUT was 14.36±3.40 seconds, and the mean staining value of the rose bengal was 1.98±0.80 in normal subjects, whereas these values were 1.36±0.49 mm, 5.46±1.33 seconds, 6.62±0.86, respectively, in patients with dry eye syndrome. When we compared the results of lacrimal scintigraphy and the results of ophthalmologic tests, an inverse correlation was noted between both the T1/2 and RI values and both the Schirmer-1 and BUT values in all subjects (p<0.001). However, there was a greater positive correlation between the rose bengal ocular surface staining value and both the T1/2 and RI values in all cases (p<0.001). In the current study, it was concluded that although the lacrimal drainage system was normal, tear clearance was significantly delayed in dry eye patients. With this study, we have shown that quantitative lacrimal scintigraphy, which is an objective, practical, and noninvasive method, appears to be useful for the assessment of the tear clearance in patients with dry eye syndrome.

    Autologous serum eye drops are considered safe and efficient for the treatment of various ocular surface disorders, including dry eye diseases (DED) caused by the primary and secondary Sjogren syndrome (SS). However, the serum components in patients of SS may be different from those of normal patients and can thus lead to unpredictable therapeutic effects. This study divided the SS patients into active and inactive types based on the erythrocyte sedimentation rate and the presence or absence of active rheumatoid arthritis. We compared the serum components of these two groups with standard and multiplex enzyme linked immunosorbent assay arrays and predicted the therapeutic effects of topical autologous serum for the treatment of DED with ocular surface disease index (OSDI) and Oxford Schema scale (OSS). Hyaluronic acid and transforming growth factor b1 levels were significantly higher in the active SS group compared to the inactive SS group ( P Sjogren dry eye patients into active and inactive groups may appear as a reasonable method to predict the quality of autologous serum eye drops, but there seems to be no significant predictability to the therapeutic effects.

    Full Text Available Purpose: To evaluate the changes in meniscus parameters with optical coherence tomography (OCT after treatment and consider the correlation between the OCT parameters and dry-eye tests. Material and Method: Thirty-two dry-eye patients and 30 healthy individuals were included. Visual acuities, biomicroscopic evaluation, Schirmer-I test, tear-break-up time (T-BUT, and lower-tear meniscus parameters measured with OCT were evaluated. Ocular surface disease index (OSDI was performed. The measurements were repeated on the 10th day and 1st month of the treatment. Lower tear meniscus height (LTMH, depth (LTMD, area (LTMA and α-angle were measured. The tear meniscus parameters of the dry-eye group were compared with the control group before treatment, and the correlation between the dry-eye tests and OCT measurements were evaluated. The change in the results of the dry-eye tests and OCT measurements with treatment were assessed. Results: There was statistically no significant difference between the age and gender of the patients in groups. Before treatment the mean Schirmer-I test, TBUT and OSDI scores were different. The LTMH and LTMA were higher in the control group. In the dry-eye group before treatment, there was a negative correlation between the OSDI score and OCT parameters, however, no meaningful correlation was observed between any other test and OCT parameters. Although there were no change in LTMD and α-angle with treatment, the 1st month values of LTMH and LTMA were significantly higher from the pre-treatment and 10th day values. Discussion: When diagnosing dry-eye, TBUT and OSDI scores were found to be more effective compared to Schirmer-I test for the diagnosis of dry eye. Although not adequate by itself, tear meniscus parameters measured with OCT, LTMH and LTMA, may be helpful for evaluating the efficacy of treatment, and the correlation of these two parameters with the OSDI score may increase the objectivity while questioning the

    The purpose of the study was to investigate if xerostomia (dry mouth) is associated with symptoms and signs of dry eye disease (DED). At the Norwegian Dry Eye Clinic, patients with symptomatic DED with different etiologies were consecutively included in the study. The patients underwent a comprehensive ophthalmological work-up and completed self-questionnaires on symptoms of ocular dryness (Ocular Surface Disease Index [OSDI] and McMonnies Dry Eye Questionnaire) and the Sjögren's syndrome (SS) questionnaire (SSQ). Three hundred and eighteen patients (52% women and 48% men) with DED were included. Patient demographics were: 0 to 19 years (1%), 20 to 39 (25%), 40 to 59 (34%), 60 to 79 (35%) and 80 to 99 (5%). Xerostomia, defined as "daily symptoms of dry mouth the last three months" (as presented in SSQ) was reported by 23% of the patients. Female sex was more common among patients with xerostomia (81%) than among non-xerostomia patients (44%; Pxerostomia (60 ± 15 years) were older than those without xerostomia (51 ± 17; Pxerostomia patients (65%) than among non-xerostomia patients (35%; Pxerostomia had a higher OSDI score (19.0 ± 10.0) than those without xerostomia (12.9 ± 8.0; Pxerostomia patients had more pathological meibum expressibility (0.9 ± 0.7) than those without xerostomia (0.7 ± 0.8; P = 0.046). Comparisons of OSDI and ocular signs were performed after controlling for the effects of sex, age and the number of systemic prescription drugs used. In conclusion, xerostomia patients demonstrated a higher DED symptom load and had poorer meibum expressibility than non-xerostomia patients.

    To determine the levels of Th17-associated cytokines, particularly interleukin (IL)-17 and IL-22 in tears of patients with dry eye syndrome. Tear samples were collected from 20 healthy volunteers, 20 dry eye (DE) patients with non-Sjögren's syndrome (NSSDE) and 20 DE patients with Sjögren's syndrome (SSDE). Symptom questionnaire was self-administered and multiple dry eye disease (DED)-related clinical tests were performed. The levels of IL-17 and IL-22 in tears were measured by enzyme-linked immunosorbent assay. The levels of IL-17 and IL-22 were significantly increased in tears of DE patients compared with those of controls and also higher in SSDE patients compared with those of NSSDE patients (Ptear film break-up time and Schirmer I test in both NSSDE and SSDE patients (Ptears were significantly increased in DE patients, which were associated with the disease severity. Therefore, Th17 cell-associated cytokines, particularly IL-17 and IL-22, may have important roles in the immunopathogenesis of the DED.

    The aim of the study reported here was to assess the efficacy of an artificial tear emulsion for the treatment of dry eye associated with meibomian gland dysfunction (MGD). At five clinics, patients completed a 1-week treatment with their habitual topical therapy and then a 4-week treatment with open-label study medication: Systane® Balance Lubricant Eye Drops (Alcon, Alcon Inc, Fort Worth, TX, USA). Subjective assessments included a preference survey, the Impact of Dry Eye in Everyday Life questionnaire, and the Work Productivity and Activity Impairment questionnaire. Objective assessments by unmasked investigators included visual acuity, meibomian gland expression and dropout, tear film breakup time, corneal staining, and dosing frequency. At baseline, the 49 patients had mean meibomian gland expression grades and gland dropout that indicated mild to moderate MGD. Patients administered their habitual therapy 2.5 ± 1.3 times per day. After 4 weeks of study medication, the Impact of Dry Eye in Everyday Life questionnaire results indicated statistically and clinically significant improvements. Fewer than half of the participants were employed, limiting the usefulness of the Work Productivity and Activity Impairment questionnaire. Visual acuity remained statistically similar, while corneal staining and tear film breakup time improved significantly (P < 0.05) but modestly. The outcomes were achieved with 1.9 ± 1.1 doses per day of study medication, a significantly lower frequency than the habitual frequency (P < 0.001). The most common medication-related adverse event was blurred vision (3/49 patients, 6.1%). At study conclusion, 27/44 (61.4%) survey respondents preferred the study medication to their habitual therapy. The artificial tear emulsion was effective for treating the signs and symptoms of dry eye in MGD patients.

    To evaluate the effects of oral anticholinergic (OAC) drugs on tear secretion in women with overactive bladder over a 3-month follow-up period. In this prospective study, 108 women with a diagnosis of overactive bladder were evaluated. All patients were examined ophthalmologically at baseline (day 0), and after 1 month (day 30) and 3 months (day 90) of OAC treatment. Tear film break-up time (BUT) and Schirmer 1 test results were recorded. The subjective complaints of the patients including dry mouth, and burning, dryness and foreign body sensation in the eyes, were also recorded. The chi-squared test or the paired sample t test as appropriate, was used for statistical analysis. The mean age of the patients was 51.8 ± 9.2 years (30 - 69 years). The most frequent subjective complaints were dry mouth and dry eyes and both complaints were significant on both day 30 and day 90. Both tear film BUT and Schirmer 1 test results were significantly lower on day 30 and day 90. Dry eye measurement values worsened with prolongation of OAC treatment (p = 0.037 and p = 0.012 for BUT, and p = 0.046 and p = 0.035 for Schirmer 1 test, on day 30 and day 90, respectively). OAC treatment in women with overactive bladder significantly and progressively affects tear secretion.

    Aging and oxidative stress seem to play a key role in the onset and progression of ocular surface diseases. Dry Eye Syndrome (DES) is a multifactorial disease of the tears and ocular surface in which symptoms may interfere with the ability to work and carry out daily functions. This clinical trial was a pilot study to evaluate the effects of supplementation with mixture (Saccharomyces boulardii MUCL 53837 and Enterococcus faecium LMG S-28935) on the tear film. Following the run-in period subjects were randomized in two groups: group A (n.30 subjects) and group B (n.30 subjects). Group A (control) treated only with substitute tear and group B treated with substitute tear + mixture (probiotic). The data obtained in the two study groups A and B were, respectively the following: Schirmer I: 9.2±0.2 vs. 12.8±0.4 (pSaccharomyces boulardii MUCL 53837 and Enterococcus faecium LMG S-28935) activity integration with the action of tear substitutes, along with standardization of clinical parameters of the tear film and microbiological activity in restoring of the microbiota ocular surface subject with DES.

    In recent decades infrared thermography (IRT) has facilitated accurate quantitative measurements of the ocular surface temperature (OST), applying a non-invasive procedure. The objective of this work was to develop a procedure based on IRT, which allows characterizing of the cooling of the ocular surface of patients suffering from dry eye syndrome, and distinguishing among patients suffering from aqueous deficient dry eye (ADDE) and evaporative dry eyes (EDE). All patients examined (34 females and 4 males, 23-84 years) were divided into two groups according to their Schirmer I result (⩽ 7 mm for ADDE and  >  7 mm for EDE), and the OST was recorded for 7 s at 30 Hz. For each acquisition, the temperatures of the central cornea (CC) as well as those of both temporal and nasal canthi were investigated. Findings showed that the maximum temperature variation (up to 0.75  ±  0.29 °C) was at the CC for both groups. Furthermore, patients suffering from EDE tended to have a higher initial OST than those with ADDE, explained by the greater quantity of the tear film, evenly distributed over the entire ocular surface, keeping the OST higher initially. Results also showed that EDE patients had an average cooling rate higher than those suffering from ADDE, confirming the excessive evaporation of the tear film. Ocular thermography paves the way to become an effective tool for differentiating between the two different etiologies of dry eye syndrome.

    To examine the morphological changes in the meibomian glands of eyes of patients with dry eye disease using the non-contact infrared meibography system and to assess their relationship with meibomian dropout, signs, and tear-film function. Subjects included 264 randomly selected patients (528 eyes) suffering from dry eye disease (95 males, 169 females; age range, 7-85 years; mean male age, 39.83 ± 19.17 years; mean female age, 46.16 ± 17.38 years). Tear-film break-up time (BUT) was measured and tear-film production was evaluated by the Schirmer test I (SIT). Subjective symptoms were also scored. The upper and lower eyelids were turned over, and the meibomian glands were observed using the non-contact meibography system. Partial or complete loss of the meibomian glands (meibomian dropout) was scored for each eyelid from grade 0 (no loss) through grade 3 (lost area was >2/3 of the total meibomian gland area). The average SIT result was 6.71 ± 6.13 mm (range 0-30 mm) and that for BUT was 3.13 ± 2.39 s (range 0-10 s). The average fluorescein staining score was 4.25 ± 4.05 (range 0-12). In addition, the mean meibomian gland photographic score was 4.35 ± 1.39. The correlation between the meibomian gland photographic scores and various ocular surface examinations were evaluated using Kendall's correlation. SIT and BUT were significantly negatively correlated with the meibomian gland photographic score, whereas corneal fluorescein staining was positively correlated. The results suggest a large proportion of meibomian dropout cases among patients with dry eye disease, indicating that treatment targeted at the meibomian gland will become an important direction for treating dry eye disease. Meibography is recommended as a routine test for dry eye disease.

    Full Text Available BACKGROUND According to the National Eye Institute, dry eye is a condition in which the eye does not produce tears properly. It can also involve tears not having the right consistency or evaporating too quickly. Tears are necessary to help maintain moisture on the surface of the eye and for clear vision. Diabetes is often associated with several significant ocular conditions such as retinopathy, refractive changes, cataracts, glaucoma and macular oedema. However, one of the most common ocular complications associated with diabetes is dry eye. The aim of the study is to study the prevalence of dry eyes in diabetes mellitus and to evaluate ocular and other risk factors relevant to diabetic dry eyes. MATERIALS AND METHODS A hospital-based cross-sectional clinical study of 100 diabetic patients who presented to the Department of Ophthalmology, Santosh Medical College and Hospital, Ghaziabad, between January 2016 to June 2017 was conducted. Detailed diabetic history was recorded. Assessment of anterior segment via slit-lamp biomicroscopy was done. The examinations for dry eyes included Schirmer's test, tear breakup time, fluorescein and rose Bengal staining. RESULTS Sixty two (62% diabetic patients had dry eye. The prevalence in type I was 3% and prevalence in type II was 59%. Dry eye prevalence was maximum in those above 40 years of age. Symptoms like reduced corneal sensation (44% and meibomitis (20% were major attributable risk factors. Ocular surface damage was predominantly superficial punctate keratitis. Retinopathy was not statistically associated with the prevalence of dry eyes. CONCLUSION Diabetes and dry eye appears to be a common association. Reduction in the modifiable risk factors of dry eye is essential to reduce its prevalence. No significant statistical correlation was found between retinopathy and dry eyes. However, examination for dry eyes should be an integral part of the assessment of diabetic eye disease.

    To develop and validate a comprehensive patient-reported outcomes instrument focusing on the impact of dry eye on everyday life (IDEEL). Development and validation of the IDEEL occurred in four phases: 1) focus groups with 45 dry eye patients to develop a draft instrument, 2) item generation, 3) pilot study to assess content validity in 16 patients and 4) psychometric validation in 210 subjects: 130 with non-Sjögren's keratoconjunctivitis sicca, 32 with Sjögren's syndrome and 48 controls, and subsequent item reduction. Focus groups identified symptoms and the associated bother, the impact of dry eye on daily life and the patients' satisfaction with their treatment as the central concepts in patients' experience of dry eye. Qualitative analysis indicated that saturation was achieved for these concepts and yielded an initial 112-item draft instrument. Patients understood the questionnaire and found the items to be relevant indicating content validity. Patient input, item descriptive statistics and factor analysis identified 55 items that could be deleted. The final 57-item IDEEL assesses dry eye impact constituting 3 modules: dry eye symptom-bother, dry eye impact on daily life comprising impact on daily activities, emotional impact, impact on work, and dry eye treatment satisfaction comprising satisfaction with treatment effectiveness and treatment-related bother/inconvenience. The psychometric analysis results indicated that the IDEEL met the criteria for item discriminant validity, internal consistency reliability, test-retest reliability and floor/ceiling effects. As expected, the correlations between IDEEL and the Dry Eye Questionnaire (a habitual symptom questionnaire) were higher than between IDEEL and Short-Form-36 and EuroQoL-5D, indicating concurrent validity. The IDEEL is a reliable, valid and comprehensive questionnaire relevant to issues that are specific to dry eye patients, and meets current FDA patient-reported outcomes guidelines. The use of this

    To compare the antioxidant and inflammatory cytokine activities in tears of patients with dry eye syndrome treated with preservative-free versus preserved eye drops. A total of 100 patients with moderate to severe dry eye syndrome were randomly divided into two groups. Fifty patients (group 1) were treated four times with preservative-free 0.1% sodium hyaluronate and 0.1% fluorometholone eye drops in the first month and with preservative-free 0.1% sodium hyaluronate and 0.05% cyclosporine eye drops in the second and third months. Another 50 patients (group 2) were treated with preserved eye drops on the same schedule. Ocular Surface Disease Index, corneal fluorescein staining, Schirmer I test, tear film breakup time, impression cytology, and antioxidant and inflammatory cytokine activities in tears were evaluated. Treatment with preservative-free eye drops led to significant improvements in symptoms, tear film breakup time, Schirmer I score, and impression cytologic findings compared to treatment with preserved eye drops (P dry eye syndrome. There was a statistically significant decrease in the IL-1β, IL-6, IL-12, and TNF-α concentrations and a statistically significant increase in the catalase, peroxiredoxin 2, superoxide dismutase 2 (SOD 2), and thioredoxin mean fluorescence intensity (MFI) of tears in the preservative-free group at 1, 2, and 3 months compared to initial values, respectively (P eye drops is effective against the dry eye syndrome. Preservative-free eye drops seem to be more effective than preserved eye drops in decreasing ocular inflammation and in increasing antioxidant contents in tears of patients with dry eye syndrome.

    To investigate effects of punctal occlusion on global tear protein levels in patients with dry eye. In this prospective, longitudinal, single-center study, nonabsorbable punctal plugs were inserted bilaterally into the lower punctum of 30 patients with moderate dry eye. Dry eye symptoms, fluorescein corneal staining, Schirmer I test, tear film break-up time, and safety were assessed in the more severely affected eye. Tear proteins at weeks 1 and 3 were quantified by iTRAQ relative to baseline preocclusion levels. Of 29 patients who completed the study, 23 (mean age 49.8 years) had sufficient tear samples for analysis. After 3 weeks, punctal occlusion significantly upregulated tear proteins, including glutathione synthase (mean of 1.6-fold, P = 0.01) and interleukin-1 receptor antagonist (1.7-fold, P = 0.032) and downregulated cholinergic receptor (neuronal) alpha-7 (0.79-fold, P = 0.039) and lymphocyte cytosolic protein-1 (0.66-fold, P = 0.012). Clustering analysis of global tear proteins revealed two clear profile changes; the first group of patients (cluster 1, n = 10) had a reduction in the inflammatory proteins (e.g., S100A8) and rise in lacrimal proteins supporting the ocular surface (e.g., lysozyme), whereas the second group (cluster 2, n = 13) had an increase in inflammatory proteins and a decrease in lacrimal proteins. Logistic regression analysis revealed that cluster 1 patients had significantly (P = 0.006) lower Schirmer scores at baseline (mean [standard deviation]: 4.3 [4.3] mm) than cluster 2 (6.8 [2.6] mm). Punctal plugs produced a beneficial pattern of tear protein change in patients with relatively low Schirmer scores within 3 weeks of punctal occlusion. Copyright © 2017 The Authors.

    We designed a randomized, double blinded, 3-months controlled prospective clinical study to investigate effects of oral uridine on the ocular surface in dry eye patients. Twenty-seven patients who diagnosed as dry eye with lower than 5 mm of wetting in the Schirmer strip, with corneal epithelial erosion and who completely followed-up till 3 months were enrolled. Corneal-conjunctival fluorescein staining, non-anesthetic Schirmer test, impression cytology, and Ocular Surface Disease Index (OSDI) were evaluated in the experimental and placebo groups at the baseline, 1 and 3 months after start of medication in a double blinded manner. Fluorescein stain score of the cornea was markedly decreased in oral uridine group compared to the placebo group at 3 months after medication (P=0.032, Mann-Whitney U test). The Schirmer wetting score for the oral uridine group was significantly increased (P=0.001, Wilcoxon signed rank test) at 3 months and its difference between two groups was statistically significant (P=0.030, Mann-Whitney U test). OSDI scores were significantly decreased at 1 and 3 months in treatment group. Oral uridine is effective in treatment of dry eyes.

    To evaluate how patient satisfaction after cataract surgery is associated with postoperative visual acuity, visual functioning, dry eye signs and symptoms, health anxiety, and depressive symptoms. Fifty-four patients (mean age: 68.02 years) were assessed 2 months after uneventful phacoemulsification; 27 were unsatisfied with their postoperative results and 27 were satisfied. They completed the following questionnaires: Visual Function Index-14 (VF-14), Ocular Surface Disease Index (OSDI), Shortened Health Anxiety Inventory (SHAI), and Shortened Beck Depression Inventory. Testing included logarithm of the Minimum Angle of Resolution (logMAR) uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), dry eye tests (tear meniscus height and depth measured by spectral optical coherence tomography, tear film break-up time (TBUT), ocular surface staining, Schirmer 1 test, and meibomian gland dysfunction grading). Postoperative UCVA, BCVA, and the dry eye parameters - except TBUT - showed no statistically significant difference between the two groups (p > 0.130). However, the VF-14 scores, the OSDI scores, and the SHAI scores were significantly worse in the unsatisfied patient group (p 0.05). However, the VF-14 scores correlated with the OSDI scores (r = -0.436, p dry eye symptoms (odds ratio = 1.46, 95% CI = 1.02-2.09, p = 0.038) and visual functioning (odds ratio = 0.78, 95% CI = 0.60-1.0, p = 0.048). Our results suggest that patient-reported visual functioning, dry eye symptoms, and health anxiety are more closely associated with patients' postoperative satisfaction than with the objective clinical measures of visual acuity or the signs of dry eye.

    The objective of this study was to determine the clinical benefits of pulsed light therapy for the treatment of Dry Eye Syndrome (DES) due to the decrease in aqueous tear production (aqueous deficient DES) and/or excessive tear evaporation (evaporative DES) due to Meibomian Gland Dysfunction (MGD). A study was conducted on 72 eyes corresponding to 36 patients with DES. Out of these 72 eyes, 60 underwent refractive surgery (48 with femtosecond laser, 6 were operated with a mechanical microkeratome, and 6 with refractive photo-keratectomy[RPK], 6 treated with phacoemulsification, and 6 with no previous surgical treatment. Pulsed laser light (Intense Pulsed Light Regulated [IRPL ® ]) was use to stimulate the secretion of the Meibomian glands during 4 sessions, one every 15 days. Patients with aqueous deficient DES did not show any improvement. Eyes with no previous surgery and those treated with phacoemulsification and PRK had a favourable outcome. On the other hand, less conclusive results were observed in the eyes treated with excimer laser. This treatment could be very helpful to treat evaporative DES produced by MGD. On the other hand, it is not helpful for those cases related to an isolated damage in the aqueous phase, or the mucin phase. Copyright © 2017 Sociedad Española de Oftalmología.

    This study was performed to evaluate the prevalence and clinical characteristics of dry eye disease (DED) in community-based type 2 diabetic patients and to identify the associated factors related with DED. A total of 1360 type 2 diabetic patients in the Beixinjing community were randomly selected. All participants were given a questionnaire that assessed basic information and subjective symptoms.DED was diagnosed using the revised Japanese DED diagnostic criteria. All subjects underwent a routine ophthalmic examination, corneal sensitivity test, tear film break-up time(BUT) test, Schirmer I test, fluorescein and lissamine green staining(FL) and fundus photography. Diabetic retinopathy (DR) was graded according to the International severity scale of diabetic retinopathy and diabetic macular edema. Of the 1360 subjects, 238 (17.5%) were diagnosed with DED. There was a significant association between the presence of DED and higher blood glucose (P dry eye examination should be added to the routine screening of diabetes.

    Full Text Available To evaluate the mRNA and protein expressions of NLRP3 inflammasome and its downstream inflammatory factors in human dry eye.We recruited 54 patients with Sjögren's syndrome dry eye (SSDE, 50 patients with non-Sjögren's syndrome dry eye (NSSDE, and 46 healthy controls. Tear film breakup time (TBUT, Schirmer I test, and fluorescein staining (FL were performed on all subjects. Tear samples were obtained to analyze the inflammatory cytokine levels of IL-1β and IL-18 via enzyme-linked immunosorbent (ELISA. Conjunctival impression cytology (CIC specimens were collected to detect the mRNA expression of NLRP3, caspase-1, IL-1β, and IL-18 using quantitative RT-PCR, and the protein expression of NLRP3 and caspase-1 by Western blotting.NLRP3 mRNA expression showed higher levels in both dry eye groups compared with controls, with a comparably significant elevation in the SSDE group (relative 2.47-fold upregulation, p<0.05. NLRP3 protein expression was also increased in SSDE group (relative1.94-fold upregulation compared with the controls. mRNA expression of caspase-1 was significantly upregulated in both SSDE (relative 1.44-fold upregulation, p<0.05 and NSSDE (relative 1.32-fold upregulation, p<0.05. Procaspase-1 protein level was increased in SSDE (relative 1.84-fold upregulation and NSSDE (relative 1.12-fold upregulation versus controls; and caspase-1 protein expression was also increased in SSDE (relative 1.49-fold upregulation and NSSDE (relative 1.17-fold upregulation compared with the controls. The patients with SSDE and NSSDE had higher IL-1β and IL-18 mRNA values and protein expressions than the controls did. The relative mRNA expression of IL-1β upregulated 3.59-fold (p<0.001 in SSDE and 2.13-fold (p<0.01 in NSSDE compared with the controls. IL-1β protein level also showed significant upregulation in SSDE (p=0.01; vs. controls groups.

    To quantify and compare the amounts of surfactant proteins SP-A, SP-B, SP-C and SP-D in the tear fluid collected from patients with dry eye syndrome and from individuals with a healthy ocular surface. Schirmer strips were used to collect tear fluid from both eyes of 241 volunteers (99 men, 142 women; age range: 18-87 years). Dry eye syndrome was diagnosed by ophthalmologists in 125 patients, whereas the healthy control group comprised 116 individuals. The total protein concentration was determined via Bradford assay. The relative concentration of surfactant proteins SP-A through -D was measured by enzyme-linked immuno-sorbent assay (ELISA). The mean relative concentrations of SP-A, SP-C and SP-D were significantly higher in the dry eye group as compared to the healthy controls (pdry eye group, but the difference to the control group was not statistically significant. The upregulation of SP-A and SP-D in the dry eye group is probably related to these proteins' known antimicrobial and immunomodulatory effects at the ocular surface. It may represent a pathophysiological response to the inflammatory condition of the ocular surface in dry eye. The upregulation of SP-B and SP-C may represent an effort of the lacrimal system to reduce surface tension and thus to counteract the increased tendency of the tear film to tear in dry eye.

    Full Text Available To investigate the characteristics of ocular surface sensations and corneal sensitivity during the interblink interval before and after tear supplementation in dry eye patients.Twenty subjects (41.88±14.37 years with dry eye symptoms were included in the dry eye group. Fourteen subjects (39.13±11.27 years without any clinical signs and/or symptoms of dry eye were included in the control group. Tear film dynamics was assessed by non-invasive tear film breakup time (NI-BUT in parallel with continuous recordings of ocular sensations during forced blinking. Corneal sensitivity to selective stimulation of corneal mechano-, cold and chemical receptors was assessed using a gas esthesiometer. All the measurements were made before and 5 min after saline and hydroxypropyl-guar (HP-guar drops.In dry eye patients the intensity of irritation increased rapidly after the last blink during forced blinking, while in controls there was no alteration in the intensity during the first 10 sec followed by an exponential increase. Irritation scores were significantly higher in dry eye patients throughout the entire interblink interval compared to controls (p0.05.Ocular surface irritation responses due to tear film drying are considerably increased in dry eye patients compared to normal subjects. Although tear supplementation improves the protective tear film layer, and thus reduce unpleasant sensory responses, the rapid rise in discomfort is still maintained and might be responsible for the remaining complaints of dry eye patients despite the treatment.

    To evaluate the efficacy and safety profile of carbomer-based lipid-containing artificial tear formulations (CBLAT) in patients with dry eye syndrome. A multicenter parallel-group study was conducted in 412 patients with dry eye syndrome. Of these patients, 221 switched from using artificial tears to CBLAT (switching group) and 191 added CBLAT to their current treatment (add-on group). Ocular symptom scores, ocular staining grades, tear film breakup time (tBUT), Schirmer I test value, and Korean dry eye level (as defined by the Korean Corneal Disease Study Group guidelines) were evaluated at baseline and after 4 weeks of treatment. After 4 weeks of treatment, ocular surface staining grade, tBUT, Schirmer I value, ocular irritation symptom scores, and the positive rate of visual symptom improved significantly in both groups. Mean reductions in ocular surface staining grades (-0.8 ± 0.9) and ocular irritation symptom scores (-0.8 ± 0.8) in the add-on group were significantly higher than those (-0.5 ± 0.8 and -0.6 ± 0.8) in the switching group (P dry eye level was 30.1% in the switching group and 51.6% in the add-on group. More patients in the add-on group had decreased dry eye levels than those in the switching group (P dry eye syndrome.

    Full Text Available BACKGROUND Globally, an estimate of 422 million adults are living with diabetes mellitus according to the latest 2016 data from the WHO. In India, as per 2015 data, there were 69.2 million cases of diabetes present. Of these, it remains undiagnosed in more than 30 million people. Dry Eye Workshop (DEWS in 2007 improvised the definition for DEWS as follows- “Dry eye is a multifactorial disease of the tears and ocular surface that results in symptoms of discomfort, visual disturbance and tear film instability with potential damage to the ocular surface. It is accompanied by occurrence of increased osmolality of tear film and inflammation of the ocular surface.” MATERIALS AND METHODS In our study, 100 cases of maturity onset of type 2 diabetic patients both male and female between age group 30 and 90 years were studied. All 100 cases of type 2 diabetes patients already on oral antidiabetic drugs, insulin or combined treatment reported to eye OPD directly as well as referred from diabetology and medical OPD and ward were subjected to routine ophthalmological examination including Schirmer's test I, TBUT, corneal sensitivity test, blood sugar fasting and postprandial, blood pressure record, HbA1C in selected cases. Clinical data of all patients, which included sex, age, duration of diabetes, family history of diabetes, BMI as well as a history of other associated hypertension and renal failure were recorded in all patients. HIV association, recent ocular surgery, corneal oedema, viral keratitis, Hansen, post LASIK surgery, meibomian gland dysfunction were excluded from our study.

    To evaluate dry eye in patients with fibromyalgia (FM). Fifty-three FM patients and 53 age and sex well-matched controls were included in this study. Visual analog scale (VAS), number of tender points, FM impact questionnaire (FIQ), Beck depression scale (BDS), Ocular Surface Disease Index (OSDI), the tear break-up time (TBUT), Schirmer test, and tear osmolarity (TO) were assessed. The OSDI, TBUT, Schirmer test, and TO scores of the FM and control groups were significantly different (P FIQ, and TBUT and TO were higher in FM with high BDS. In FM patients, Schirmer test was correlated with the VAS (r = -0.429, P = 0.001), BDS (r = -0.277, P = 0.044), and FIQ (r = -0.382, P = 0.005), and the TBUT was correlated with the VAS (r = -0.537, P FIQ (r = -0.456, P = 0.001). In addition, TO was significantly correlated with the VAS (r = 0.681, P FIQ (r = 0.842, P FIQ. We have revealed an association between FM disease activity and dry eye severity. The consideration of this relation will be useful in the treatment of FM with deteriorated clinical status.

Twenty patients with moderate to severe dry eye were enrolled in a 28-day prospective, randomized, controlled study. Subjects self-administered the HPG containing ocular lubricant four times daily (QID) over the study duration. After 28 days, the effect of the HPG containing ocular lubricant was evaluated by means of the Global Staining Score (a measure of the corneal and conjunctival staining), inter-blink tear film stability, Ocular Protection Index (OPI), and subjective symptoms. The HPG containing ocular lubricant produced statistically significant improvements compared with baseline in dry eye symptoms (P eye symptoms with the HPG containing ocular lubricant -- evident as early as the first follow-up visit (Day 7) and continued throughout the 28 days of the study with a concurrent, increase in OPI to a level greater than unity -- indicate that this preparation is a fast-acting, long-lasting, and effective treatment for dry eye. In concurrence with the results from previously published clinical studies, the HPG containing ocular lubricant has shown efficacy in alleviating the signs and symptoms of dry eye as well as affording improved ocular surface protection.

    Full Text Available Jesús Tellez-Vazquez On behalf of the Dry Eye In Glaucoma Study Group (DEIGSG Glaucoma Section, Ophthalmology Department, Hospital de la Santa Creu i Sant Pau, Barcelona, Spain Purpose: The purpose of this study is to assess the effectiveness and tolerability of a dietary supplement with a combination of omega-3 fatty acids and antioxidants on dry eye symptoms caused by chronic instillation of antihypertensive eye drops in patients with glaucoma. Patients and methods: A total of 1,255 patients with glaucoma and dry eye symptoms related to antiglaucoma topical medication participated in an open-label, uncontrolled, prospective, and multicenter study and were instructed to take three capsules a day of the nutraceutical formulation (Brudypio® 1.5 g for 12 weeks. Dry eye symptoms (graded as 0–3 [none to severe, respectively], conjunctival hyperemia, tear breakup time, Schirmer I test, Oxford grading scheme, and intraocular pressure were assessed. Results: After 12 weeks of administration of the dietary supplement, all dry eye symptoms improved significantly (P<0.001 (mean 1.3 vs 0.6 for scratching, 1.4 vs 0.7 for stinging sensation, 1.6 vs 0.7 for grittiness, 1.0 vs 0.4 for tired eyes, 1.1 vs 0.5 for grating sensation, and 0.8 vs 0.3 for blurry vision. The Schirmer test scores and the tear breakup time also increased significantly. There was an increase in the percentage of patients grading 0–I in the Oxford scale and a decrease in those grading IV–V. Compliance was recorded in 62.5% of patients. In compliant patients, the mean differences at 12 weeks vs baseline of dry eye symptoms were statistically significant as compared to noncompliant patients. Conclusion: Dietary supplementation with Brudypio® may be a clinically valuable additional option for the treatment of dry eye syndrome in patients with glaucoma using antiglaucoma eye drops. These results require confirmation with an appropriately designed randomized controlled study

    Objectives To compare expression of interleukin (IL)-1β and tumour necrosis factor (TNF)-α in the conjunctiva of diabetic and non-diabetic patients with symptomatic moderate dry eye. Setting and participants Nineteen diabetic patients with dry eye, 15 non-diabetic patients with dry eye and 14 diabetic patients without dry eye were recruited. The relative expression of IL-1β and TNF-α in conjunctival impression cytology (CIC) specimens was evaluated using immunofluorescent staining and in conjunctival biopsy specimens using immunohistochemical staining. Results The diabetic dry eye group showed significantly higher grades of metaplasia than the non-diabetic dry eye and diabetic without dry eye groups (both pdry eye group was significantly increased compared with the non-diabetic dry eye and diabetic without dry eye groups (p=0.002, pdry eye, while levels of IL-1β and TNF-α in apical conjunctival epithelium were similar in the CIC specimens. These findings suggest that the inflammatory response is not limited to the surface of conjunctival epithelial cells, and is more serious in the basal layer of the epithelium, which may play an important role in the pathogenesis of dry eye in diabetic patients.

    To investigate the effects of diquafosol on intraocular pressure (IOP) and dry eye symptoms in glaucoma patients with dry eye syndrome (DES). This study evaluated a total of 138 glaucoma patients with DES who were treated with diquafosol ophthalmic solution (DIQUAS(®)). Before treatment and 1, 4, 12, 36, and 52 weeks after treatment, IOP, ocular surface disease index (OSDI), tear film break-up time (BUT), Schirmer I test scores, fluorescein staining, conjunctival impression cytology, and adverse drug reactions were evaluated. Throughout the treatment period, the mean IOP for all the patients remained stable after treatment with diquafosol (15.4 ± 2.8 mmHg at baseline and 16.0 ± 2.8 mmHg at 52 weeks). The mean OSDI score improved significantly at 4, 12, and 52 weeks after diquafosol treatment. The BUT and Schirmer I test scores were significantly increased after diquafosol treatment. The Oxford scheme score was significantly decreased at 1, 4, 12, 36, and 52 weeks after diquafosol treatment. A significant improvement in goblet cell density was observed after 4 weeks of treatment with diquafosol. Adverse drug reactions were reported in 22 (15.9 %) patients. There were no serious adverse drug reactions. Diquafosol was effective in improving objective and subjective symptoms and maintained a stable IOP in glaucoma patients with DES. Therefore, the addition of diquafosol treatment in glaucoma patients with DES or ocular surface side effects using anti-glaucoma medication may be beneficial.

    To determine the possibility of the development of dry eye disease (DED) as a result of persistent infection with Chlamydia trachomatis and Ureaplasma urealyticum in the conjunctiva of patients. This study was conducted on 58 patients of age range 20-50y, diagnosed with DED confirmed by Schirmer I test and tear breakup time. The non-dry eye control group included 27 subjects of the same age. Ocular specimens were collected as conjunctival scrapings and swabs divided into three groups: the first used for bacterial culture, the second and third taken to detect Chlamydia trachomatis and Ureaplasma urealyticum by direct fluorescent antibody (DFA) assay and polymerase chain reaction (PCR) method. Chlamydia trachomatis was detected in 65.5% and 76% of DED patients by DFA and PCR methods respectively. Ureaplasma urealyticum was found in 44.8% of DED infected patients using the PCR method. Both organisms were identified in only 37.9% of DED patients found to be infected. Control subjects had a 22% detection rate of Chlamydia trachomatis by DFA assay versus a 7% detection rate by PCR; while Ureaplasma urealyticum was detected in 3.7% of the controls by PCR method. The conjunctival culture revealed that gram positive microorganisms represented 75% of isolates with coagulase negative Staphylococci the most common (50%) followed by Staphylococcus aureus (20%), whereas gram negative microorganisms occurred in 25% of cases, isolating Moraxella spp. as the most frequent organism. Our results tend to point out that Chlamydia trachomatis and Ureaplasma urealyticum were detected in a moderate percentage of patients with DED, and could be a fair possibility for its development. PCR is more reliable in detecting Chlamydia trachomatis than DFA technique. The presence of isolated conjunctival bacterial microflora can be of some potential value.

    Dry eye syndrome can be difficult to manage in severe or refractory cases. In patients in whom traditional treatments have limited efficacy, alternative treatments may be considered for dry eye syndrome, including scleral lenses. The present review summarizes the evidence regarding scleral lens use in dry eye syndrome. Scleral lenses have become a viable option for severe dry eye syndrome, and have been shown to be efficacious and well tolerated, with most reports citing improved visual acuity and relief of symptoms. Currently, there are 18 manufacturers of scleral lenses, although published reports on scleral lenses primarily focus on the BostonSight PROSE and the Jupiter Lens. Scleral lenses are efficacious and well tolerated for use in severe dry eye syndrome. Further research is needed to compare different sizes and types of lenses, and to standardize outcome measures.

    Until recently, the cause of dry eye syndrome was uncertain and the treatment was palliative. Since discovering that dry eyes are caused by inflammation, there has been an abundance of research focusing on anti-inflammatory therapies, other contributing causes, and better diagnostic testing. This review summarizes some of the interesting published research on ocular surface disease over the past year. The definition of dry eye now highlights the omnipresent symptom of blurry vision. The re-evaluation of ocular surface staining, tear meniscus height, and visual change will allow for a better diagnosis and understanding of dry eyes. Punctal plugs, and oral and topical anti-inflammatory use will strengthen our arsenal against ocular surface disease. Major progress has occurred in the past few years in gaining a better understanding of the etiology of dry eye syndrome, which will inevitably lead to more effective therapeutic options.

    Full Text Available BACKGROUND Dry eye disease is one of the most common ocular surface disorder with large number of studies carried out in various countries estimate the prevalence of dry eye disease to be between 5-34%. The prevalence of dry eye increases with age. As per Breaver Dam study regarding dry eye the prevalence of DED 13.3%. Dry eye was apparently higher in women than men. Studies have shown that cataract surgery worsen dry eye symptoms in patients with preexisting dry eye symptoms as well as without preexisting DES, mostly dry eye symptoms last for two months of post cataract surgery period. MATERIALS AND METHODS The prospective observational study was conducted in Department of Ophthalmology, Government Vellore Medical College and Hospital, Vellore. The total number of cataract surgery performed cases were 140 in number. The study period was four months, conducted in tertiary eye center. The Cataract patients were preoperatively at normal tear secretions. Post cataract surgery period from first POD, one week POD, four weeks, six weeks, two months and three months POD examined by slit lamp, Schirmer's test I, TBUT and corneal sensitivity test were performed. RESULTS Our study revealed that increased prevalence in female sex with increased age group range from 51-70 years showed post cataract surgery period dryness of eye. The ratio of Post cataract surgery DED in male and female is 13:29. This shows increased female sex prevalence of postoperative DED. In our study, the prevalence of post cataract surgery dry eye disease was 30%. CONCLUSION 73% cataract surgeries is now clear corneal cataract surgery and this procedure cuts a large part of corneal nerves. The nerve essential for tear production gets disturbed leading to dryness and hence decreased visual function. The corneal nerves are important in self-regulation of tears since they provide the sensation in the feedback loop that signals tear production. When the functions of the nerves get blocked

    Background Theoretically, autologous serum eye drops (AS) offer a potential advantage over traditional therapies on the assumption that AS not only serve as a lacrimal substitute to provide lubrication but contain other biochemical components that allow them to mimic natural tears more closely. Application of AS has gained popularity as second-line therapy for patients with dry eye. Published studies on this subject indicate that autologous serum could be an effective treatment for dry eye. Objectives We conducted this review to evaluate the efficacy and safety of AS given alone or in combination with artificial tears as compared with artificial tears alone, saline, placebo, or no treatment for adults with dry eye. Search methods We searched CENTRAL (which contains the Cochrane Eyes and Vision Trials Register) (2016, Issue 5), Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid MEDLINE Daily, Ovid OLDMEDLINE (January 1946 to July 2016), Embase (January 1980 to July 2016), Latin American and Caribbean Literature on Health Sciences (LILACS) (January 1982 to July 2016), the ISRCTN registry (www.isrctn.com/editAdvancedSearch), ClinicalTrials.gov (www.clinicaltrials.gov) and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en). We also searched the Science Citation Index Expanded database (December 2016) and reference lists of included studies. We did not use any date or language restrictions in the electronic searches for trials. We last searched the electronic databases on 5 July 2016. Selection criteria We included randomized controlled trials (RCTs) that compared AS versus artificial tears for treatment of adults with dry eye. Data collection and analysis Two review authors independently screened all titles and abstracts and assessed full-text reports of potentially eligible trials. Two review authors extracted data and assessed risk of bias and characteristics of included

    To investigate the effects of artificial tear treatment on central corneal epithelial thickness, and central, mid-peripheral and peripheral corneal thicknesses in patients with dry eye disease (DED). Patients with DED underwent ocular examinations, including Schirmer-2 test, slit lamp examination for tear break-up time (BUT), corneal topography (CT) for measuring mean central, mid-peripheral and peripheral corneal thickness values and anterior segment optic coherence tomography (AS-OCT) for obtaining central corneal epithelial thickness. After artificial tear treatment (carboxymethylcellulose and sodium hyaluronate formulations) for one month, patients were examined again at a second visit and the results were compared. Sixty-one eyes of 33 female dry eye patients (mean age: 38.3±5.7 years) were enrolled. The mean follow-up time was 36.4±3.3 days. The mean tear BUT and Schirmer-1 tests revealed significant improvement after treatment (P=0.000, P=0.000, respectively). Central corneal epithelium and mean mid-peripheral corneal thicknesses measured significantly higher after treatment (P=0.001, P=0.02). Changes in central and peripheral corneal thicknesses were not statistically significant. Artificial tear treatment in dry eye patients seems to increase central corneal epithelial and mid-peripheral corneal thicknesses. Measurement of corneal epithelial thickness can be a useful tool for evaluation of treatment response in dry eye patients. Further long-term prospective studies are needed to investigate this item.

    Full Text Available Cynthia Matossian,1,2 Joan Micucci1 1Matossian Eye Associates, Doylestown, PA, USA; 2Department of Ophthalmology, Temple University School of Medicine, Philadelphia, PA, USA Purpose: The purpose was to characterize the biomarkers associated with Sjögren’s syndrome (SS identified in the serological samples of patients with recalcitrant dry eye disease; additionally, the modalities utilized in the treatment of dry eye disease were evaluated for subsets of patients with and without SS. Patients and methods: Data for this retrospective, single-center, pilot study were based on a chart review of 48 sequential patients with recalcitrant dry eye who were evaluated for SS via serological analysis. Data presented include the presence of the autoantibodies identified through the serological biomarker analysis and identification of the concurrent dry eye treatment modalities. Results: Eleven out of 48 patients (23% tested positive for biomarkers associated with SS. Autoantibodies for salivary protein-1, parotid secretory protein 1, and carbonic anhydrase VI, markers associated with the early development of SS, were detected in 91% (ten out of eleven of the patients who tested positive for SS, whereas 27% (three out of eleven of patients tested positive for the traditional SS markers, SS-A and/or SS-B. Common treatment modalities utilized in SS patients included omega-3 supplements (82%, topical cyclosporine (74%, and artificial tear solutions (64%, as compared to omega-3 supplements (80%, hot-mask therapy (77%, and artificial tear solutions (77%, in SS-negative patients. Conclusion: Evaluation for salivary protein-1, parotid secretory protein 1, and carbonic anhydrase VI biomarkers allows for identification of a subset of patients with biomarkers associated with SS that may not be identified through the traditional assessments (SS-A/SS-B.

    There has been rapid progress in our understanding of dry eye pathogenesis, as well as the development of improved diagnostic clinical tests. Various types of dry eye treatment drugs have been developed. This review summarizes the basic and clinical research carried out in the development of diquafosol for ophthalmic use. Diquafosol is a dinucleotide, purinoreceptor P2Y(2) receptor agonist. Basic pharmacological studies have shown that it acts on P2Y(2) receptors at the ocular surface, to promote tear and mucin secretion via elevated intracellular Ca(2+) concentrations. Diquafosol also improves tear and mucin secretion in experimental dry eye models. Based on the results of laboratory experiments, the authors conducted a series of clinical studies in patients with dry eye disease. Diquafosol was effective in the treatment of dry eye disease at an optimal dose of 3% six times a day. In comparison to commercially available 0.1% sodium hyaluronate ophthalmic solution, 3% diquafosol ophthalmic solution showed non-inferiority in improving corneal fluorescein staining scores and superiority in improving keratoconjunctival Rose Bengal staining scores. Diquafosol ophthalmic solution has a novel mechanism of action that is characterized by its stimulatory effects on tear and mucin secretion. This drug has the potential to be effective in patients with tear film instability and short break-up time type of dry eye, which are essential factors in dry eye pathogenesis.

    An acidic mammalian chitinase (AMCase) seems to be implicated in allergic asthma and allergic ocular pathologies. The aim of this work was to investigate the role of AMCase during Sjögren's Syndrome (SS) and Meibomian Gland Dysfunction (MGD) dry eye diseases. Six patients with MGD dry eye (20-58 years, median 40) and six patients with dry eye associated to SS (32-60 years, median 47) were enrolled in this study. AMCase activity was measured in tears and AMCase mRNA expression was evaluated by real-time polymerase chain reaction from RNA extracted from epithelial cells of the conjunctiva. Six healthy adult subjects of the same age (34-44 years, median 39) were also studied as the control group. AMCase activity was significantly increased in patients affected by MGD dry eye (18.54 +/- 1.5 nmol/ml/h) and SS dry eye (8.94 +/- 1.0 nmol/ml/h) respectively, compared to healthy controls (1.6 +/- 0.2 nmol/ml/h). AMCase activity was higher in the tears of subjects with MGD dry eye (P < 0.001). AMCase mRNA was detected in conjunctival epithelial cells and the expression was significantly higher in MGD dry eye than SS dry eye. A significant correlation between AMCase activity in the tears and mRNA in conjunctival epithelial cells was found. AMCase may be an important marker in the pathogenesis of dry eye, suggesting the potential role of AMCase as a therapeutic target in these frequent pathologies.

  10. IMAGE-GUIDED EVALUATION AND MONITORING OF TREATMENT RESPONSE IN PATIENTS WITH DRY EYE DISEASE

    Dry eye disease (DED) is one of the most common ocular disorders worldwide. The pathophysiological mechanisms involved in the development of DED are not well understood and thus treating DED has been a significant challenge for ophthalmologists. Most of the currently available diagnostic tests demonstrate low correlation to patient symptoms and have low reproducibility. Recently, sophisticated in vivo imaging modalities have become available for patient care, namely, in vivo confocal microscopy (IVCM) and optical coherence tomography (OCT). These emerging modalities are powerful and non-invasive, allowing real-time visualization of cellular and anatomical structures of the cornea and ocular surface. Here we discuss how, by providing both qualitative and quantitative assessment, these techniques can be used to demonstrate early subclinical disease, grade layer-by-layer severity, and allow monitoring of disease severity by cellular alterations. Imaging-guided stratification of patients may also be possible in conjunction with clinical examination methods. Visualization of subclinical changes and stratification of patients in vivo, allows objective image-guided evaluation of tailored treatment response based on cellular morphological alterations specific to each patient. This image-guided approach to DED may ultimately improve patient outcomes and allow studying the efficacy of novel therapies in clinical trials. PMID:24696045

    There are as many as one-third of the systemic lupus erythematosus (SLE) patients who suffer from dry eye syndrome. To this date, dry eye syndrome in SLE patients is believed to be caused by secondary Sjogren syndrome (sSS). However, there is increasing evidence for possible independency of dry eye syndrome and sSS in patients suffering from autoimmune diseases. The purpose of this retrospective observational case series was to identify SLE patients without sSS who had dry eye syndrome, examine the correlation of different autoantibodies and dry eye severity, and determine the cause of dry eye in these patients.We included 49 consecutive SLE patients with dry eye who visited our dry eye clinic. In order to rule out sSS, these patients were all negative for anti-Sjogren's-syndrome-related antigen A and B (anti-SSA/SSB) and had no oral symptoms. Each patient's lupus activity was determined by serological tests including antidouble-stranded DNA antibody (anti-dsDNA), complement levels (C3, C4), erythrocyte sedimentation rate (ESR), and antinuclear antibody (ANA). Severity of dry eye syndrome was determined by corneal sensation (KSen), superficial punctuate keratopathy (SPK), Schirmer-I test (Schirmer), and tear film break-up time (TBUT). The autoantibodies and the dry eye parameters in each group were tested using the χ test or the Mann-Whitney U test for normally distributed or skewed data, respectively.The anti-dsDNA showed significant correlations with KSen (P dry eye parameters were observed between C4, ESR, and ANA.The major finding of this study was that the severity of dry eye syndrome in SLE patients without sSS was strongly correlated with anti-dsDNA and C3 but not with C4, ESR, and ANA.

    To evaluate the corneal confocal microscopy and dry eye findings in patients with contact lens discomfort. The study included 3 groups of participants: Contact lens wearers using silicone hydrogel soft contact lenses who are symptomatic (CLD, n=15) or asymptomatic (ACL, n=11) and non-wearers as controls (n=14). Duration of contact lens wear, Ocular Surface Disease Index (OSDI) questionnaire responses, fluorescein tear break-uptime (FBUT), and corneal confocal microscopy findings were recorded. Mean age was 25.7±8.2 years and male/female ratio was 7/33. Demographic findings were similar regarding the groups. CLD patients had a longer lens use history than ACL (median 5 vs 2 years, pCLD group than ACL or controls (pCLD group, compared to controls and ACL (pCLD group compared to controls but similar to ACL (pCLD group than the ACL (p=0.014). Patients with CLD had been wearing contact lenses for longer than those without symptoms. OSDI and FBUT scores were worse in CLD patients. In contact lens discomfort patients, there were increased dendritiform cells, indicating intensified inflammatory status of the cornea. Copyright © 2017 British Contact Lens Association.

    The objective of this study was to investigate the effect of dietary supplementation with omega-3 fatty acids on ocular surface and tear film in patients with type 2 diabetes suffering from dry eye. Thirty-six patients suffering from type 2 diabetes and moderate to severe dry eye syndrome were included in the study. Patients were assigned to receive omega-3 long-chain polyunsaturated fatty acids for 3 months. Tear film break-up time test, Schirmer-I test, and conjunctival impression cytology analysis were performed on all patients at baseline and after 1 and 3 months. The subjective symptoms of dry eye were evaluated with the Ocular Surface Disease Index (OSDI) questionnaire at the same time points. Patients' average age was 65.57 ± 4.27 years and the mean duration of diabetes was 14.85 ± 5.4 years. There was a statistically significant increase in Schirmer-I test results and tear break-up time score after 3 months of supplementary intake of omega-3 fatty acids compared to baseline (p dry eye syndrome in patients with type 2 diabetes.

    To determine the effects of clinical variables, including age, sex, history of refractive or cataract surgery, contact lens use, and ocular surface and meibomian gland parameters on the lipid layer thickness (LLT) in normal subjects and patients with dry eye syndrome (DES). A total of 64 normal subjects and 326 patients with DES were enrolled, and they underwent measurements of LLT with a LipiView interferometer and tear meniscus height using optical coherence tomography, tear film break-up time (TBUT) determination, ocular surface staining, Schirmer's test, examination of the lid margins and meibomian glands, and assessment using the Ocular Surface Disease Index (OSDI). In normal subjects, the median (range) LLT was 67 (33-100) nm, and age was the only factor that was significantly associated with LLT (β = 0.678, P = 0.028). In patients with DES, the median (range) LLT was 84 (20-100) nm, and 79.0% of the participants fulfilled the diagnostic criteria for meibomian gland dysfunction (MGD). In a multivariate analysis, increased age and female sex were significantly related to increased LLT (β = 0.282, P = 0.005 and β = 11.493, P < 0.001), and hypersecretory MGD and lid margin inflammation were independently associated with increased LLT (β = 11.299, P = 0.001 and β = 12.747, P = 0.001). Lipid layer thickness measurements using a new interferometer are significantly affected by demographic factors such as age, sex, ocular surgical history, and MGD type. Therefore, all of these factors must be considered in the diagnosis of ocular surface diseases.

  15. Aging: A Predisposition to Dry Eyes

    Directory of Open Access Journals (Sweden)

    Anushree Sharma

    2014-01-01

    Full Text Available Dry eye syndrome is a disease of the ocular surface and tear film that is prevalent in older adults. Even though the degree of visual acuity loss in dry eye patients is commonly mild-to-moderate, in the aging population, this minimal change in visual status can lead to a significant decrease in visual function and quality of life. A healthy ocular surface is maintained by appropriate tear production and tear drainage, and deficiencies in this delicate balance can lead to dryness. In the aging eye, risk factors such as polypharmacy, androgen deficiency, decreased blink rates, and oxidative stress can predispose the patient to developing dry eye that is frequently more severe, has higher economic costs, and leads to worse consequences to the well-being of the patient. Understanding why elderly patients are at higher risk for developing dry eyes can provide insights into the diagnosis and management of the growing number of older adults struggling with dry eye and minimize the burden of disease on our aging population.

    To noninvasively investigate regional differences in tear film stability and meibomian glands in patients with aqueous-deficient dry eye. Forty-nine dry eyes and 31 normal eyes were analyzed. A corneal topographer with a tear film scanning function was used for noninvasive tear film break-up time (NI-TFBUT) measurements and meibomian gland observations. The NI-TFBUT values and location of the first tear film break-up point were recorded in four quadrants. Meibomian gland loss was graded for each eyelid using meiboscores. Lid margin abnormality was scored from zero to four according to the number of existing abnormalities. The NI-TFBUT values and meiboscores were compared between two groups, and regional differences in NI-TFBUT values and meiboscores were analyzed. Also, the correlation between the NI-TFBUT and ocular surface examination results were investigated. The NI-TFBUT values and meiboscores were significantly lower and higher, respectively, for the dry eye group than for the normal group. In the dry eye group, the occurrence rate for first tear film break-up was the highest in the inferior nasal quadrant, and the mean meiboscore was significantly higher for the upper eyelids than for the lower eyelids. The NI-TFBUT and lid margin abnormality scores showed a weak negative correlation, and the NI-TFBUT values and meiboscores showed no correlation. Compared to normal eyes, aqueous-deficient dry eyes show significant regional differences in tear film stability and meibomian glands. Considering these regional differences, the overall observation of the ocular surface, including both upper and lower eyelids, will aid clinicians in understanding this condition better.

    2012-03-01

    Allergic conjunctivitis (AC) and dry eye syndrome (DES) are 2 of the most common anterior inflammatory disorders of the ocular surface and one does not preclude the coexistence of the other. To examine the potential overlap between AC and DES as comorbidities. Using the validated questionnaire known as Subjective Evaluation of Symptom of Dryness, we studied self-reported itchiness, dryness, and redness. In an outpatient optometric setting, 689 patients treated from January 1, 2007, to January 1, 2011, were surveyed for their ocular history and categorized according to their reported level of discomfort of itchiness, dryness, and redness. Patients ranged in age from 5 to 90 years (median age, 25 years; 39.5% male; 60.5% female). In the studied 689 patients, clinically significant itchiness was found in 194 (28.2%), dry eyes in 247 (35.8%), and redness in 194 (28.2%). Symptom overlap was demonstrated in many of the patients. Of the 194 patients with itchiness, 112 (57.7%) had clinically significant dryness. In the 247 patients with dry eyes, 112 (45.3%) had clinically significant itch. Redness was apparent in 120 of the 194 patients with itch (61.9%) and 122 of the 247 patients with dryness (49.4%). Statistical analysis demonstrated that self-reported itchiness, dryness, and redness were not independent of each other (Peyes" also experiencing dry eyes were 2.11 times and the odds of these patients also experiencing redness were 7.34 times that of patients with nonitchy eyes. Most patients with "itchy eyes" consistent with AC also have dry eyes and redness. These results suggest that some symptomatic patients concomitantly have features of AC and DES.

    Aromatase inhibitors are frequently used as an adjuvant therapy in the treatment of breast cancer. We observed that several patients taking aromatase inhibitors presented with severe dry eye symptoms, and we investigated whether there is a relationship between aromatase inhibitors and dry eyes in these patients. Retrospective chart review. Forty-one women. A computerized search of health records was performed to identify patients using anastrazole, letrozole and exemestane seen by the Cornea Service from August 2008 to March 2011. The results were compared with age-matched controls. Ocular surface changes among aromatase inhibitors users. Of the 41 women, 39 were Caucasians. Thirty-nine patients had breast cancer (95%), one patient had ovarian cancer (2.5%) and one had an unknown primary cancer. Mean age was 68 ± 11.3 years (range 47-95). Most common presenting symptoms were blurred vision in 28 (68%) patients, irritation/foreign body sensation in 12 (29%) patients, redness in 9 (22%) patients, tearing in 6 (22%) patients and photosensitivity in 2 (5%) patients. Mean Schirmer's test measurement was 11 ± 5.8 mm (range 0.5-20 mm). Blepharitis was noted in 68 of 82 eyes (73%), decreased or poor tear function in 24 eyes (29%), conjunctival injection in 18 eyes (22%) and superficial punctate keratitis in 12 eyes (29%). Among an age-matched population (45-95 years), dry eye syndrome was found in only 9.5% of patients. Because the prevalence of ocular surface disease signs and symptoms appears to be higher in study group than control patients, aromatase inhibitors might be a contributing factor to the dry eye symptoms. © 2012 The Authors.

    In vivo corneal confocal microscopy allows the examination of each layer of the cornea in detail and the identification of pathological changes at the cellular level. The purpose of this study was to identify the possible effects of a three-month treatment with autologous serum eye-drops in different corneal layers of patients with severe dry eye disease using corneal confocal microscopy. Twenty-six patients with dry eye disease were included in the study. Corneal fluorescein staining was performed. The corneas of the right eyes were examined using in vivo corneal confocal microscopy before and after a three-month treatment with autologous serum drops. The densities of superficial and basal epithelial cells, Langerhans cells, the keratocytes and activated keratocytes, the density of endothelial cells and the status of the sub-basal nerve plexus fibres were evaluated. A significant decrease in corneal fluorescein staining was found after the three-month autologous serum treatment (p = 0.0006). The basal epithelial cell density decreased significantly (p = 0.001), while the density of superficial epithelial cells did not change significantly (p = 0.473) nor did the number of Langerhans cells or activated keratocytes (p = 0.223; p = 0.307, respectively). There were no differences in the other corneal cell layers or in the status of the nerve fibres. The results demonstrate the ability of corneal confocal microscopy to evaluate an improvement in the basal epithelial cell layer of the cornea after autologous serum treatment in patients with dry eye disease. More studies with longer follow-up periods are needed to elucidate the suitability of corneal confocal microscopy to follow the effect of autologous serum treatment on nerve fibres or other corneal layers in dry eye disease patients. © 2016 Optometry Australia.

    Patients with dry eye syndrome are known to suffer from anxiety and depression. Analysis of psychological disorders in therapy-resistant dry eye syndrome. A retrospective analysis of the training for interactive psychiatric screening (TRIPS) questionnaire from 110 patients with therapy-resistant dry eye syndrome was carried out. The results of the questionnaire allow the diagnosis of psychological disorders and vegetative disorders. Patients were divided into groups with anxiety, depression, mixed diagnoses, vegetative disorders and no diagnosis. A sicca score was used for assessment of dryness comprising the Schirmer test, measurement of tear meniscus, break up time, lipid layer thickness, the use of fluorescein and rose bengal staining tests and the subjective visual analogue scale. The diagnosis of dry eye syndrome was compared with the psychological disorders of anxiety and depression. Of the patients 52.7 % had psychological disorders with anxiety in 21.8 %, depression in 15.3 %, mixed diagnoses in 14.5 %, dystonia in 25.4 % and in 22.7 % no psychological disorders were diagnosed. General anxiety was frequent and panic disorders were often associated with other kinds of anxiety. Severe depression, such as bipolar disorder was rare. Dry eye scores were highest in the mixed group (0.59), and lowest in the group with mild anxiety (0.38). No single sicca phase disorder could be correlated with any of the psychological diagnoses. Patients with therapy-resistant dry eye syndrome often suffer from anxiety and depression. The psychological stress acts on the nervous system to suppress lacrimal gland function. Further investigation of the correlation between the lacrimal tear film phase and psychological disorders is recommended. Knowledge of personality disorders may allow psychological support that would improve the treatment options for dry eye syndrome.

    Diquafosol ophthalmic solution improves objective findings in the ocular surface and subjective symptoms in patients with dry eye. The Dry Eye-Related Quality-of-Life Score (DEQS) questionnaire was developed to assess dry eye symptoms and their effects on quality of life. However, because little research using the DEQS has been reported, we evaluated the effects of diquafosol ophthalmic solution on ocular surface findings and quality of life using the DEQS in patients with dry eye. Sixty-three patients with dry eye were assigned to the control group (artificial tears) or diquafosol group. Both groups instilled 1 drop of the solution in both eyes 6 times daily and were evaluated after 2 weeks; the diquafosol group also was instructed to be examined at 1 and 3 months. We evaluated the subjective symptoms using the DEQS, fluorescein staining score, tear film breakup time (BUT), Schirmer testing, and lower tear meniscus height with anterior-segment optical coherence tomography. In the diquafosol group, the fluorescein staining score, BUT, tear meniscus height, and DEQS scores improved significantly compared with before treatment in contrast to the control group. Furthermore, in the diquafosol group, the staining score and BUT improved significantly compared with the control group. Analysis of each DEQS item indicated that diquafosol ophthalmic solution relieved foreign body sensation and problems when reading and using visual display terminals compared with the control group. Diquafosol ophthalmic solution was effective in patients with dry eye, especially those with foreign body sensation and problems when reading and using visual display terminals.

    This article presents the results of an international, multicenter, randomized, double-masked, placebo-controlled clinical study of Visomitin (Mitotech LLC, Moscow, Russian Federation) eye drops in patients with dry eye syndrome (DES). Visomitin is the first registered (in Russia) drug with a mitochondria-targeted antioxidant (SkQ1) as the active ingredient. In this multicenter (10 sites) study of 240 subjects with DES, study drug (Visomitin or placebo) was self-administered three times daily (TID) for 6 weeks, followed by a 6-week follow-up period. Seven in-office study visits occurred every 2 weeks during both the treatment and follow-up periods. Efficacy measures included Schirmer's test, tear break-up time, fluorescein staining, meniscus height, and visual acuity. Safety measures included adverse events, slit lamp biomicroscopy, tonometry, blood pressure, and heart rate. Tolerability was also evaluated. This clinical study showed the effectiveness of Visomitin eye drops in the treatment of signs and symptoms of DES compared with placebo. The study showed that a 6-week course of TID topical instillation of Visomitin significantly improved the functional state of the cornea; Visomitin increased tear film stability and reduced corneal damage. Significant reduction of dry eye symptoms (such as dryness, burning, grittiness, and blurred vision) was also observed. Based on the results of this study, Visomitin is effective and safe for use in eye patients with DES for protection from corneal damage. Mitotech LLC.

    "Dry eye syndrome" is a common disorder of the tear film that results from inadequate tear production, excessive tear evaporation or abnormality in mucin or lipid components of the tear film. A number of 53 patients suffering from dry eye syndrome were followed up for a period of 18 months. The study group was heterogeneous, including a lot of conditions accompanied by dry eye syndrome: Syogren's syndrome, lupus erythematous, ocular rosacea, patients with systemic treatments with antidepressants, betablockers, diuretics, oral contraceptives, glaucomatous patients with topical beta-blockers, postmenopausal women, aging people, computer users and long-term contact lens wearers. The therapeutical options were dictated by the severity of the syndrome: substitution therapy, treatment of the underlying eyelid diseases, modifying of the environmental conditions and treatment of the complications in the most severe cases. The new pathological approach is innovative and it may provide a real therapeutical measure for this condition: topical A Cyclosporine and androgen drops.

    Dry eye is a common ocular surface disease of multifactorial etiology characterized by elevated tear osmolality and inflammation leading to a disrupted ocular surface. The latter is a risk factor for ocular surface infection, yet overt infection is not commonly seen clinically in the typical dry eye patient. This suggests that important innate mechanisms operate to protect the dry eye from invading pathogens. This article reviews the current literature on epidemiology of ocular surface infection in dry eye patients and laboratory-based studies on innate immune mechanisms operating at the ocular surface and their alterations in human dry eye and animal models. The review highlights current understanding of innate immunity in dry eye and identifies gaps in our knowledge to help direct future studies to further unravel the complexities of dry eye disease and its sequelae.

    Diabetes mellitus has been shown to be associated with and complicated by dry eye syndrome. We sought to examine and compare the tear film proteome of type 2 diabetic patients with or without dry eye syndrome and normal subjects using two-dimensional nano-liquid chromatography coupled with tandem mass spectrometry (MS)-based proteomics. Tears were collected from eight type 2 diabetes patients with dry eye syndrome, eight type 2 diabetes patients without dry eye syndrome, and eight normal subjects. Tear breakup time (BUT) was determined, and tear proteins were prepared and analyzed using two-dimensional strong cation-exchange/reversed-phase nano-scale liquid chromatography MS. All MS/MS spectra were identified by using SEQUEST against the human International Protein Index (IPI) database and the relative abundance of individual proteins was assessed by spectral counting. Tear BUT was significantly lower in patients with diabetes and dry eye syndrome than in patients with diabetes only and normal subjects. Analysis of spectral counts of tear proteins showed that, compared to healthy controls, patients with diabetes and dry eye syndrome had increased expression of apoptosis-related proteins, like annexin A1, and immunity- and inflammation-related proteins, including neutrophil elastase 2 and clusterin, and glycometabolism-related proteins, like apolipoprotein A-II. Dry eye syndrome in diabetic patients is associated with aberrant expression of tear proteins, and the findings could lead to identification of novel pathways for therapeutic targeting and new diagnostic markers.

    To compare the efficacy and safety of 3% diquafosol ophthalmic solution with those of 0.1% sodium hyaluronate ophthalmic solution in dry eye patients, using mean changes in fluorescein and rose bengal staining scores as endpoints. TRIAL DESIGN AND METHODS: In this multicenter, randomised, double-masked, parallel study of 286 dry eye patients with fluorescein and rose bengal staining scores of ≥3 were randomised to the treatment groups in a 1 : 1 ratio. Efficacy and safety were evaluated after drop-wise instillation of the study drug, six times daily for 4 weeks. After 4 weeks, the intergroup difference in the mean change from baseline in fluorescein staining score was -0.03; this verified the non-inferiority of diquafosol. The mean change from baseline in rose bengal staining score was significantly lower in the diquafosol group (p=0.010), thus verifying its superiority. The incidence of adverse events was 26.4% and 18.9% in the diquafosol and sodium hyaluronate groups, respectively, with no significant difference. Diquafosol (3%) and sodium hyaluronate (0.1%) exhibit similar efficacy in improving fluorescein staining scores of dry eye patients, whereas, diquafosol exhibits superior efficacy in improving rose bengal staining scores. Diquafosol has high clinical efficacy and is well tolerated with a good safety profile.

    To examine the effect of a single dose of artificial tear administration on automated visual field (VF) testing in patients with glaucoma and dry eye syndrome. A total of 35 patients with primary open-angle glaucoma experienced in VF testing with symptoms of dry eye were enrolled in this study. At the first visit, standard VF testing was performed. At the second and third visits with an interval of one week, while the left eyes served as control, one drop of artificial tear was administered to each patient's right eye, and then VF testing was performed again. The reliability parameters, VF indices, number of depressed points at probability levels of pattern deviation plots, and test times were compared between visits. No significant difference was observed in any VF testing parameters of control eyes (P>0.05). In artificial tear administered eyes, significant improvement was observed in test duration, mean deviation, and the number of depressed points at probability levels (P˂0.5%, P˂1%, P˂2) of pattern deviation plots (P˂0.05). The post-hoc test revealed that artificial tear administration elicited an improvement in test duration, mean deviation, and the number of depressed points at probability levels (P˂0.5%, P˂1%, P˂2%) of pattern deviation plots from first visit to second and third visits (P˂0.01, for all comparisons). The intraclass correlation coefficient for the three VF test indices was found to be between 0.735 and 0.85 (P<0.001, for all). A single dose of artificial tear administration immediately before VF testing seems to improve test results and decrease test time.

    Dry eye syndrome is a disease of the ocular surface and tear film that is prevalent in older adults. Even though the degree of visual acuity loss in dry eye patients is commonly mild-to-moderate, in the aging population, this minimal change in visual status can lead to a significant decrease in visual function and quality of life. A healthy ocular surface is maintained by appropriate tear production and tear drainage, and deficiencies in this delicate balance can lead to dryness. In the aging...

    To determine the effect of topical 0.05% cyclosporine A (CsA) on corneal endothelium in patients with dry eye disease. Observational, prospective, case series study. Fifty-five eyes of 29 consecutive patients (9 males and 20 females; median age: 66.8 years, interquartile range: 61-73.2 years) with moderate-severe dry eye disease were evaluated. All patients were treated with topical 0.05% CsA ophthalmic emulsion twice a day in addition to lubricant eyedrops 5 times a day. The follow-up period was 12 months. Before treatment and at 3 and 12 months post-treatment central corneal specular microscopy was performed. The endothelial cell density (ECD), coefficient of variation of cell size (CoV), and percentage of hexagonal cells (Hex %) were analyzed. The median ECDs pre-treatment and at 3 and 12 months post-treatment were 2 352.5/mm(2) (interquartile range, 2 178-2 548.5), 2364/mm(2) (interquartile range, 2 174.25-2 657.5), and 2366 cells/mm(2) (interquartile range, 2 174.75-2 539.75), respectively (P=0.927, one way ANOVA). The median CoVs pre-treatment and at 3 and 12 months post-treatment were 34.5 (interquartile range, 30-37), 35 (interquartile range, 30-38), and 34 (interquartile range, 30.75-38.25), respectively (P=0.7193, one way ANOVA). The median Hex % values pre-treatment and at 3 and 12 months post-treatment were 53 (interquartile range, 47-58), 54 (interquartile range, 45.75-59), and 50.5 (interquartile range, 45.75-58), respectively (P=0.824, one way ANOVA). Treatment of patients with dry eye disease for 12 months with topical 0.05% CsA does not seem to cause substantial changes on corneal endothelium.

    Sjogren's syndrome is the leading cause for aqueous tear-deficiency dry eye. Little is known regarding the relationship between Sjogren's syndrome dry eye (SSDE) and patients' medical expenditure, clinical severity and psychological status changes. Thirty-four SSDE patients and thirty non-Sjogren's syndrome dry eye (non-SSDE) subjects were enrolled. They were required to complete three self-report questionnaires: Ocular Surface Disease Index, Zung Self Rating Anxiety Scales, and a questionnaire designed by the researchers to study the patients' treatment, medical expenditure and income. The correlations between expenditures and these parameters were analyzed. The annual total expenditure on the treatment of SSDE was Chinese Yuan 7637.2 (approximately US$1173.8) on average, and the expense paid by SSDE patients themselves was Chinese Yuan 2627.8 (approximately US$403.9), which were 5.5 and 4.5 times higher than non-SSDE patients (both P < 0.001). The annual total expense on Chinese medicine and western medicine were 35.6 times and 78.4% higher in SSDE group than in non-SSDE group (both P < 0.001). Moreover, indirect costs associated with the treatment were 70.0% higher in SSDE group. In SSDE group, the score of Zung Self Rating Anxiety Scales had significantly positive correlation with total medical expenditure and the expense on Chinese medicine (ρ = 0.399 and ρ = 0.400,both P = 0.019). Nevertheless, total medical expenditure paid by the patients in non-SSDE group positively correlated with the score of Ocular Surface Disease Index (ρ = 0.386, P = 0.035). Medication expenditures and associated costs is an unignorable economic burden to the patients with SSDE. The medical expense had a significantly correlation with clinical severity of SSDE and the patients' psychological status.

    The aim of this study was to investigate the effect of topically applied ocular anesthetic proparacaine on conjunctival and nasal bacterial mucosal flora in patients with dry eye disease. A Schirmer test was done with (group 1) and without (group 2) topical anesthetic proparacaine to 40 patients in each group. Conjunctival and nasal cultures were obtained before and 10 min after performing the Schirmer test. The bacterial culture results and the isolated bacteria were recorded in two groups. Patients' mean age was 62 years (70 female, 10 male). Before the application of topical anesthetic, 50 (62.5%) and 62 (77.5%) had positive conjunctival and nasal culture, respectively, with the most commonly isolated organism being coagulase-negative Staphylococcus in each group. In group 1 the conjunctival bacterial culture positivity rate decreased from 26 (65%) to six (15%) eyes ( p 0.05). For the nasal cultures, the bacterial culture positivity rate decreased from 80% to 20% and from 75% to 65% in groups 1 ( p 0.05), respectively. Topical ocular anesthetic proparacaine has antibacterial activity in both conjunctival and nasal flora in patients with dry eye disease.

    Laser-assisted in-situ keratomileusis (LASIK) is one of the most commonly performed refractive procedures with excellent visual outcomes. Dry eye syndrome is one of the most frequently seen complications after LASIK, with most patients developing at least some mild dry eye symptoms postoperatively. To achieve improved visual outcomes and greater patient satisfaction, it is essential to identify patients prone to dry eyes preoperatively, and initiate treatment early in the course. Enhanced understanding of the pathophysiology of post-LASIK dry eye will help advance our approach to its management.

    To investigate the dose-dependent efficacy and safety of diquafosol ophthalmic solution for the treatment of dry eye syndrome. Randomized, double-masked, multicenter, parallel-group, placebo-controlled trial. A total of 286 Japanese patients with dry eye who were prescribed topical diquafosol (1%, n = 96; 3%, n = 96) or placebo ophthalmic solution (n = 94). After a washout period of 2 weeks, qualified subjects were randomized to receive a single drop of 1% or 3% diquafosol or placebo ophthalmic solutions 6 times per day for 6 weeks. The primary outcome measure was fluorescein corneal staining score assessment. The secondary outcome measures were Rose Bengal corneal and conjunctival staining scores, tear break-up time (BUT), and subjective symptom assessment. Safety measures were clinical blood and urine examination and recording of adverse events. Fluorescein corneal staining scores significantly improved with both 1% and 3% topical diquafosol compared with placebo at 4 weeks, respectively (P = 0.037, P = 0.002). There was a dose-dependent effect among the groups. Rose Bengal corneal and conjunctival staining scores also improved significantly with both 1% and 3% diquafosol compared with placebo (P = 0.007 and P = 0.004, respectively). Subjective dry eye symptom scores significantly improved with both diquafosol ophthalmic solutions (P ≤ 0.033), although there were no significant differences in BUT compared with placebo. No significant differences between the treatment groups were observed in relation to the occurrence of adverse events. Both 1% and 3% diquafosol ophthalmic solutions are considered effective and safe for the treatment of dry eye syndrome. Copyright © 2012 American Academy of Ophthalmology. Published by Elsevier Inc.

    To evaluate the efficacy of oral antioxidant supplementation in the treatment of patients with dry eye syndrome (DES). A prospective, randomized, double-blinded study compared the effects of an antioxidant supplement (containing anthocyanosides, astaxanthin, vitamins A, C, and E, and several herbal extracts, including Cassiae semen and Ophiopogonis japonicus) with placebo on patients with DES. We assessed dry eye symptoms, visual acuity, Schirmer's test, tear film breakup time, cornea and conjunctiva fluorescein staining, serum anti-SSA/anti-SSB antibodies, and the level of reactive oxygen species (ROS) in tears. The supplementation period was 8 weeks and patients were followed up every 4 weeks for 16 weeks. A linear mixed model was used to compare the groups, while within-group differences were tested by repeated-measures analysis of variance. Forty-three patients, 20 and 23 in treatment and placebo groups, respectively, completed the study. Liver and renal functions were normal. Diastolic blood pressure decreased in the treatment group. There were no significant differences in systolic blood pressure, dry eye symptoms, serum anti-SSA and anti-SSB, visual acuity, intraocular pressure, or fluorescein corneal staining between the groups. Tear film breakup time scores and Schirmer's test without topical anesthesia significantly improved in the treatment group. Tear ROS level differed between the groups and decreased after treatment. Overall subjective impression revealed a significant improvement with treatment compared with placebo. Oral antioxidant supplementations may increase tear production and improve tear film stability by reducing tear ROS. The vegetable-based antioxidant supplement used in this study is safe and can be utilized as an adjuvant therapy to conventional artificial tear therapy for patients with DES.

    To evaluate interleukin-6 (IL-6) levels in the conjunctival epithelium of patients with moderate to severe dry eye disease before and after treatment with cyclosporin A ophthalmic emulsion (CsA) or its vehicle. Conjunctival cytology specimens were obtained from a subset of patients enrolled in a 6-month randomized, double-masked clinical trial of the efficacy and safety of topical CsA at baseline and after 3 and 6 months of B.I.D. treatment with 0.05% cyclosporine emulsion (n = 13), 0.1% cyclosporine emulsion (n = 8), or vehicle (n = 10). RNA was extracted and a competitive reverse transcriptase polymerase chain reaction (RT-PCR) was used to evaluate the levels of mRNA encoding the inflammatory cytokine IL-6 and a housekeeping gene, G3PDH. Levels of IL-6 and G3PDH were measured and compared. There was no change from baseline in the level of G3PDH after 3 or 6 months in any group. IL-6 normalized for G3PDH (IL-6/G3PDH ratio) was not different from baseline at 3 months but showed a significant decrease from baseline in the group treated with 0.05% CsA (p = 0.048) at 6 months. No significant between-group differences were noted and no correlation was observed between the change in IL-6/G3PDH and corneal fluorescein staining. This preliminary, small-cohort study showed a decrease in IL-6 in the conjunctival epithelium of moderate to severe dry eye patients treated with 0.05% CsA for 6 months. The observed decrease suggests that dry eye disease involves immune-mediated inflammatory processes that may be decreased by treatment with topical ophthalmic cyclosporine.

    Dry eye can damage the ocular surface and result in mild corneal epithelial defect to blinding corneal pannus formation and squamous metaplasia. Significant progress in the treatment of dry eye has been made in the last two decades; progressing from lubricating and hydrating the ocular surface with artificial tear to stimulating tear secretion; anti-inflammation and immune regulation. With the increase in knowledge regarding the pathophysiology of dry eye, we propose in this review the concept of ocular surface microenvironment. Various components of the microenvironment contribute to the homeostasis of ocular surface. Compromise in one or more components can result in homeostasis disruption of ocular surface leading to dry eye disease. Complete evaluation of the microenvironment component changes in dry eye patients will not only lead to appropriate diagnosis, but also guide in timely and effective clinical management. Successful treatment of dry eye should be aimed to restore the homeostasis of the ocular surface microenvironment.

    To evaluate the response of the lacrimal function unit in Sjögren syndrome (SS)-associated dry eye patients exposed to 2 simulated daily life environmental conditions. Prospective crossover pilot study. Fourteen female SS dry eye patients were exposed for 2 hours to a controlled normal condition (23 C, 45% relative humidity, and air flow 0.10 m/s) and a controlled adverse condition that simulates desiccating stress (23 C, 5% relative humidity, and air flow 0.10 m/s). The following dry eye tests were performed before and after the exposure: tear osmolarity, phenol red thread test, conjunctival hyperemia, fluorescein tear break-up time, corneal fluorescein staining, conjunctival lissamine green staining, and Schirmer test. Levels of 16 molecules were analyzed in tears by multiplex immunobead analysis. Clinical evaluation showed lacrimal functional unit impairment after the desiccating stress: significantly increased tear osmolarity (315.7 ± 3.0 vs 327.7 ± 5.1 mOsm/L, P = .03), conjunctival hyperemia (1.3 ± 0.1 vs 1.6 ± 0.1, P = .05), and corneal staining in temporal (3.5 ± 0.5 vs 4.7 ± 0.4, P = .01) and nasal (3.6 ± 0.5 vs 4.5 ± 0.5, P = .04) areas. Tear concentrations increased for interleukin-1 receptor antagonist (16 557.1 ± 4047.8 vs 31 895.3 ± 5916.5 pg/mL, P = .01), interleukin-6 (63.8 ± 20.2 vs 111.5 ± 29.6 pg/mL, P = .02), interleukin-8 (2196.1 ± 737.9 vs 3753.2 ± 1106.0 pg/mL, P = .03), and matrix metalloproteinase-9 (101 515.6 ± 37 088.4 vs 145 867.1 ± 41 651.5 pg/mL, P = .03). After the simulated normal condition, only a significant increase in nasal corneal staining (2.9 ± 0.5 vs 3.6 ± 0.5, P = .03) was observed. Even a short exposure to a desiccating environment can produce a significant deterioration of the lacrimal function unit in female SS dry eye patients. The often unnoticed exposure to these conditions during daily life may increase inflammatory activity rapidly, triggering an ocular surface deterioration. Copyright © 2016

    Dry eye is a multifactorial condition that results in a dysfunctional lacrimal functional unit. Evidence suggests that inflammation is involved in the pathogenesis of the disease. Changes in tear composition including increased cytokines, chemokines, metalloproteinases and the number of T cells in the conjunctiva are found in dry eye patients and in animal models. This inflammation is responsible in part for the irritation symptoms, ocular surface epithelial disease, and altered corneal epithelial barrier function in dry eye. There are several anti-inflammatory therapies for dry eye that target one or more of the inflammatory mediators/pathways that have been identified and are discussed in detail.

    To improve understanding of dry eye disease and highlight a subgroup of patients who have a component of central sensitization and neuropathic pain contributing to their condition. Prospective, cross-sectional, IRB-approved study comparing isolated dry eye disease (n=48) to fibromyalgia (positive control; n=23) and healthy (negative control; n=26) individuals with ocular surface examination, corneal confocal microscopy, quantitative sensory testing, and self-reported ocular symptoms and systemic associations. A subset of patients also underwent skin biopsy and/or brain neuroimaging. Dry eye patients were split into concordant (ie, those with dry eyes on examination) and discordant (ie, those with dry eye symptoms but normal examination) subgroups for further analysis. We hypothesized that on the systemic measures included, concordant patients would resemble healthy controls, whereas discordant patients would show evidence of centralized mechanisms similar to fibromyalgia. Schirmer test and Ocular Surface Disease Index (OSDI) scores indicated significant decreases in tear production (Schirmer: healthy, 18.5±8.2 mm; dry, 11.2±5.4 mm; fibromyalgia, 14.4±7.5; P dry eye symptoms (OSDI: healthy, 1.9±3.0; dry, 20.3±17.7; fibromyalgia, 20.3±17.1; P dry eye and fibromyalgia patients, compared to controls. The discordant subgroup had decreased corneal nerve density and decreased visual quality-of-life scores, similar to patients with fibromyalgia. Concordant patients were more similar to healthy controls on these measures. Individuals with discordant dry eye may have a central pathophysiologic mechanism leading to their eye pain symptoms, which could be an important factor to consider in treatment of chronic idiopathic dry eye.

    The goal of this literature review is to discuss recent discoveries in the pathophysiology of dry eye and the subsequent evolution of diagnostic and management techniques. The mechanisms of various anti-inflammatory treatments are reviewed, and the efficacy of common pharmacologic agents is assessed. Anti-inflammatory therapy is evaluated in terms of its primary indications, target population, and utility within a clinical setting. The Medline PubMed database and the World Wide Web were searched for current information regarding dry eye prevalence, pathogenesis, diagnosis, and management. After an analysis of the literature, major concepts were integrated to generate an updated portrayal of the status of dry eye syndrome. Inflammation appears to play a key role in perpetuating and sustaining dry eye. Discoveries of inflammatory markers found within the corneal and conjunctival epithelium of dry eye patients have triggered recent advancements in therapy. Pharmacologic anti-inflammatory therapy for dry eye includes 2 major categories: corticosteroids and immunomodulatory agents. Fatty acid and androgen supplementation and oral antibiotics have also shown promise in dry eye therapy because of their anti-inflammatory effects. Anti-inflammatory pharmacologic agents have shown great success in patients with moderate to severe dry eye when compared with alternative treatment modalities. A deeper understanding of the link between inflammation and dry eye validates the utilization of anti-inflammatory therapy in everyday optometric practice.

    This study sought to provide an evidence-based profile of the diagnosis, treatment and knowledge or opinions on dry eye among optometrists and ophthalmologists in Ghana. This was a cross-sectional survey RESULTS: The responses of 162 participants are included in the analysis. The most commonly used test to diagnosed dry eye disease was tear break-up time followed by patient history. The most common symptom doctors heard from dry eye patients were burning sensation followed by foreign body sensation. The most often prescribed first- line treatment for dry eye was aqueous-based artificial tears followed by lipid-based artificial tears. Most practitioners considered meibomian gland dysfunction as the most common cause of dry eye followed by pterygium. The most often used test to guide or gauge therapeutic effect is patient history followed closely by tear break-up time. Most practitioners reported that 10%-20% of all their patients they see in a day are diagnosed of dry eye. This study showed tear break up time was the main test majority of practitioners in Ghana used to diagnose dry eye but patient history was the main test used to gauge therapeutic effect over time. Burning sensation was the commonest symptom practitioners heard from dry eye patients whilst artificial tears was their main and first-line treatment for dry eye.

    We present two cases of severe dry eye in patients with chronic graft-versus-host disease (CGVHD) after hematopoietic stem cell transplantation (SCT) who were successfully treated by the systemic administration of FK506 and corticosteroids. A 29-year-old man with chronic myelogenous leukemia underwent SCT. Oral and lung CGVHD developed on approximately day 130, and dry eye associated with CGVHD was diagnosed on day 168. The patient began receiving cyclosporin A (150 mg/d) for the treatment of oral and lung CGVHD. Treatment with prednisolone (1 mg/kg/d) began on approximately day 300. Oral and lung GVHD improved slightly, but worsened again although systemic administration of cyclosporin A and prednisolone were continued. Cyclosporin A was discontinued, and systemic administration of FK506 was started on day 376. Forty-four days later, marked improvement in the ocular surface and other organs was observed. However, the dry eye worsened while tapering FK506, with no flare of other affected organs. A 43-year-old woman with myelodysplastic syndrome underwent SCT. She received FK506 for prophylaxis of CGVHD. She had mild dry eye before SCT. Oral and intestinal CGVHD developed, and the dry eye worsened significantly on approximately day 150 while tapering FK506. Treatment with prednisolone (1 mg/kg/d) began, and the dose of FK506 was increased. By day 240, the symptoms of dry eye and the findings of the ocular surface markedly improved, and CGVHD in other organs was completely resolved. However, the improvement in the dry eye was lost when FK506 was tapered for the second time. Systemic administration of FK506 with corticosteroids is an effective treatment of severe dry eye in patients with CGVHD, but long-term administration may be required to achieve a lasting response. These cases also suggest that further investigation into the use of topical FK506 and prednisolone as a maintenance therapy should be pursued.

The eyes were randomly assigned to one of the two regimens in each patient: topical administration of sodium hyaluronate and diquafosol tetrasodium in one eye, and that of sodium hyaluronate in the other. Before treatment, and 2 and 4 weeks after treatment, we determined tear volume, tear film break-up time (BUT), fluorescein and rose bengal vital staining scores, subjective symptoms, and adverse events. We found a significant improvement in BUT (P=0.049, Dunnett test), fluorescein and rose bengal staining scores (P=0.02), and in subjective symptoms (P=0.004 for dry eye sensation, P=0.02 for pain, and P=0.02 for foreign body sensation) 4 weeks after treatment in the diquafosol eyes. On the other hand, we found no significant change in these parameters after treatment in the control eyes. In dry eyes, where sodium hyaluronate monotherapy was insufficient, diquafosol tetrasodium was effective in improving objective and subjective symptoms, suggesting its viability as an option for the additive treatment of such eyes.

    Keratoconjunctivitis sicca, or dry eye, is a common ocular disease prompting millions of individuals to seek ophthalmological care. Regardless of the underlying etiology, dry eye has been shown to be associated with abnormalities in the pre-corneal tear film and subsequent inflammatory changes in the entire ocular surface including the adnexa, conjunctiva and cornea. Since the recognition of the role of inflammation in dry eye, a number of novel treatments have been investigated designed to inhibit various inflammatory pathways. Current medications that are used, including cyclosporine A, corticosteroids, tacrolimus, tetracycline derivatives and autologous serum, have been effective for management of dry eye and lead to measurable clinical improvement.

    Dry-eye disease, an increasingly prevalent ocular-surface disorder, significantly alters tear physiology. Understanding the basic physics of tear dynamics in healthy and dry eyes benefits both diagnosis and treatment of dry eye. We present a physiological-based model to describe tear dynamics during blinking. Tears are compartmentalized over the ocular surface; the blink cycle is divided into three repeating phases. Conservation laws quantify the tear volume and tear osmolarity of each compartment during each blink phase. Lacrimal-supply and tear-evaporation rates are varied to reveal the dependence of tear dynamics on dry-eye conditions, specifically tear osmolarity, tear volume, tear-turnover rate (TTR), and osmotic water flow. Predicted periodic-steady tear-meniscus osmolarity is 309 and 321 mOsM in normal and dry eyes, respectively. Tear osmolarity, volume, and TTR all match available clinical measurements. Osmotic water flow through the cornea and conjunctiva contribute 10 and 50% to the total tear supply in healthy and dry-eye conditions, respectively. TTR in aqueous-deficient dry eye (ADDE) is only half that in evaporative dry eye (EDE). The compartmental periodic-steady tear-dynamics model accurately predicts tear behavior in normal and dry eyes. Inclusion of osmotic water flow is crucial to match measured tear osmolarity. Tear-dynamics predictions corroborate the use of TTR as a clinical discriminator between ADDE and EDE. The proposed model is readily extended to predict the dynamics of aqueous solutes such as drugs or fluorescent tags.

    To compare the efficacy and safety of 3% diquafosol ophthalmic solution with those of 0.1% sodium hyaluronate ophthalmic solution in patients with dry eye in China and Singapore. A total of 497 patients with dry eye (Schirmer's test, 5 mm; fluorescein and RB score, 3 points) from China and Singapore were randomised to receive either diquafosol ophthalmic solution (diquafosol) or sodium hyaluronate ophthalmic solution (HA) at 1:1 ratio. The fluorescein staining scores and rose bengal (RB) subjective symptom scores and tear film breakup time were evaluated before treatment and 2 and 4 weeks after start of treatment. In the diquafosol group, changes in fluorescein and RB scores compared with baseline at week 4 or at the time of discontinuation were -2.1±1.5 and -2.5±2.0, respectively. Compared with the HA group, changes in fluorescein score were non-inferior and changes in RB score were superior (p=0.019). In addition, diquafosol and HA improved tear film breakup time by 1.046±1.797 and 0.832±1.775 s, respectively (no significant intergroup difference). Adverse event onset rates were 16.3% (40 of 246 subjects) and 10.0% (25 of 251 subjects) in the diquafosol group and HA group, respectively, with borderline significant intergroup differences (p=0.046), while adverse drug reaction incidence rates were 12.2% (30 of 246 subjects) and 6.0% (15 of 251 subjects), respectively (p=0.019). Only mild adverse drug reactions (>2%) in the form of eye discharge, itching or irritation were observed. Diquafosol improved fluorescein staining score in a manner similar to HA, and significantly improved RB score compared with HA. NCT01101984. Published by the BMJ Publishing Group Limited.

    Purpose To improve understanding of dry eye disease and highlight a subgroup of patients who have a component of central sensitization and neuropathic pain contributing to their condition. Methods Prospective, cross-sectional, IRB-approved study comparing isolated dry eye disease (n=48) to fibromyalgia (positive control; n=23) and healthy (negative control; n=26) individuals with ocular surface examination, corneal confocal microscopy, quantitative sensory testing, and self-reported ocular symptoms and systemic associations. A subset of patients also underwent skin biopsy and/or brain neuroimaging. Dry eye patients were split into concordant (ie, those with dry eyes on examination) and discordant (ie, those with dry eye symptoms but normal examination) subgroups for further analysis. We hypothesized that on the systemic measures included, concordant patients would resemble healthy controls, whereas discordant patients would show evidence of centralized mechanisms similar to fibromyalgia. Results Schirmer test and Ocular Surface Disease Index (OSDI) scores indicated significant decreases in tear production (Schirmer: healthy, 18.5±8.2 mm; dry, 11.2±5.4 mm; fibromyalgia, 14.4±7.5; Pdry eye symptoms (OSDI: healthy, 1.9±3.0; dry, 20.3±17.7; fibromyalgia, 20.3±17.1; Pdry eye and fibromyalgia patients, compared to controls. The discordant subgroup had decreased corneal nerve density and decreased visual quality-of-life scores, similar to patients with fibromyalgia. Concordant patients were more similar to healthy controls on these measures. Conclusions Individuals with discordant dry eye may have a central pathophysiologic mechanism leading to their eye pain symptoms, which could be an important factor to consider in treatment of chronic idiopathic dry eye.

    To evaluate minor salivary glands and labial mucous membrane graft in patients with severe symblepharon and dry eye secondary to Stevens-Johnson syndrome (SJS). A prospective, non-comparative, interventional case series of 19 patients with severe symblepharon and dry eye secondary to SJS who underwent labial mucous membrane and minor salivary glands transplantation. A complete ophthalmic examination including the Schirmer I test was performed prior to and following surgery. All patients had a preoperative Schirmer I test value of zero. Nineteen patients with severe symblepharon and dry eye secondary to SJS were included in the study. There was a statistically significant improvement in the best spectacle-corrected visual acuity in eight patients (t test; p=0.0070). Values obtained in the Schirmer I test improved significantly in 14 eyes (73.7%) 6 months following surgery (χ(2) test; p=0.0094). A statistically significant increase in tear production (Schirmer I test) was found in eyes that received more than 10 glands per graft compared with eyes that received fewer glands (χ(2) test; p=0.0096). Corneal transparency improved significantly in 11 (72.2%) eyes and corneal neovascularisation improved significantly in five eyes (29.4%) (McNemar test; p=0.001 and p=0.0005). The symptoms questionnaire revealed improvement in foreign body sensation in 53.6% of the patients, in photophobia in 50.2% and in pain in 54.8% (Kruskal-Wallis test; p=0.0167). Labial mucous membrane and minor salivary glands transplantation were found to constitute a good option for the treatment of severe symblepharon and dry eye secondary to SJS. This may be considered as a step prior to limbal stem cell and corneal transplantation in these patients.

  12. Management of dry eye disease.

    The management of dry eye disease (DED) encompasses both pharmacologic and nonpharmacologic approaches, including avoidance of exacerbating factors, eyelid hygiene, tear supplementation, tear retention, tear stimulation, and anti-inflammatory agents. Artificial tears are the mainstay of DED therapy but, although they improve symptoms and objective findings, there is no evidence that they can resolve the underlying inflammation in DED. Topical corticosteroids are effective anti-inflammatory agents, but are not recommended for long-term use because of their adverse-effect profiles. Topical cyclosporine--currently the only pharmacologic treatment approved by the US Food and Drug Administration specifically for DED--is safe for long-term use and is disease-modifying rather than merely palliative. Treatment selection is guided primarily by DED severity. Recently published guidelines propose a severity classification based on clinical signs and symptoms, with treatment recommendations according to severity level.

    Diagnostic tests for dry eye disease (DED), including ocular surface disease index (OSDI), tear breakup time (TBUT), corneal fluorescein staining, and lissamine staining, have great deal of variability. We investigated whether fluorophotometry correlated with previously established DED diagnostic tests and whether it could serve as a novel objective metric to evaluate DED. Dry eye patients who have had established signs or symptoms for at least 6 months were included in this observational study. Normal subjects with no symptoms of dry eyes served as controls. Each eye had a baseline fluorescein scan prior to any fluorescein dye. Fluorescein dye was then placed into both eyes, rinsed with saline solution, and scanned at 5, 10, 15, and 30 min. Patients were administered the following diagnostic tests to correlate with fluorophotometry: OSDI, TBUT, fluorescein, and lissamine. Standard protocols were used. P eyes from 25 patients (DED = 22 eyes, 11 patients; Normal = 28 eyes, 14 patients) were included. Baseline scans of the dry eye and control groups did not show any statistical difference (p = 0.84). Fluorescein concentration of DED and normal patients showed statistical significance at all time intervals (p eyes up to 30 min after fluorescein dye instillation. There may be an aspect of DED that is missed in the current regimen of DED tests and only captured with fluorophotometry. Adding fluorophotometry may be useful in screening, diagnosing, and monitoring patients with DED.

We present the findings from four recently published studies conducted in Russia assessing Hylabak® (marketed as Hyabak® in Europe, a preservative-free hyaluronic acid preparation, for the treatment of dry eye syndrome. All studies had an open, noncomparative design, but one compared the findings with those from 25 patients treated with Tear Naturale® in previous studies. A total of 134 children and adults were enrolled, and the etiologies of dry eye syndrome included contact lens use, intensive office work, adenovirus eye infection, postmenopausal status, persistent meibomian blepharitis, Sjögren's syndrome, phacoemulsification with intraocular lens implantation, and refractive surgery. The patients were treated with Hylabak for 2 weeks to 2 months. All studies showed that Hylabak resulted in marked improvement as assessed by subjective sensations/complaints, Schirmer's test, Norn’s test, impression cytology and biomicroscopy, staining, and tear osmolarity. Greater benefits were also reported compared with Tear Naturale, including a faster onset of action. Hylabak was well tolerated. In conclusion, Hylabak provided rapid and safe relief from the signs and symptoms of dry eye syndrome, as well as improvement in objective measures, in a wide range of patients.Keywords: dry eye, eye drops, artificial tears, hyaluronic acid, Hylabak®, preservative-free

    Dry eye is defined by a tear film instability resulting in variable but systematic fluctuations in quality of vision. Variability in optical quality can be demonstrated using a double pass aberrometer such as the Optical Quality Analyzing System, Visiometrics (OQAS). The goal of this work is to compare fluctuations in objective quality of vision measured by OQAS between treatment with normal saline eye drops and treatment with carmellose 0.5% and hyaluronic acid 0.1% (Optive Fusion [OF], Allergan) in patients with moderate dry eye syndrome. Optical quality was measured by evaluating the variations in the Optical Scattering Index (OSI) over 20seconds using the OQAS. Inclusion criteria were dry eye syndrome with an ocular surface disease index (OSDI) score >23 treated only with artificial tears. The patients were their own controls: OF in one eye and normal saline in the fellow eye. The choice of the subject eye and control eye was determined in a randomized fashion. OSI variations were measured in each eye before instillation, 5minutes and 2hours after instillation. The primary endpoint was OSI fluctuation over 20seconds of measurement. Secondary endpoints were the number of blinks and patient preference (preferred eye). Preliminary results were obtained on 19 patients. Average OSDI score was 36.8. Visual acuity was 10/10 with no significant difference between the two eyes. Prior to instillation, there was no significant difference between "normal saline" and "OF" eyes in terms of OSI, OSI variability or number of blinks. In the normal saline eye, there were no significant variations in mean OSI, OSI variability, OSI slope, or number of blinks. However, in the "OF" eye, there was a significant variation between initial and 2-hour OSI variability (0.363 versus 0.204, Peye, 24% did not have a preference, and 11% preferred the normal saline eye.

    To evaluate the expression of matrix metalloproteinase 9 (MMP9) and transglutaminase 2 (TG2) in different forms of dry eye. Case control study. Seventy-five female subjects divided into 3 groups: group 1, 15 healthy controls; group 2, 30 subjects with Sjögren syndrome (SS); and group 3, 30 subjects with Meibomian gland dysfunction (MGD). A clinical assessment was carried out and impression cytologic specimens were processed for immunoperoxidase staining for MMP9 and TG2 and real-time polymerase chain reaction analyses were carried out for MMP9, TG2, interleukin-6, interferon-γ, B-cell lymphoma 2, and caspase 3. To study MMP9 and TG2 expression after anti-inflammatory treatment, patients were divided into 2 subgroups, one treated with saline and the other treated with saline plus topical corticosteroid eye drops (0.5% loteprednol etabonate) 4 times daily for 15 days. For statistical analysis, Student t test, Mann-Whitney U test, and Spearman's correlation coefficient were used as appropriate. Conjunctival expression of MMP9 and TG2. MMP9 and TG2 expression were higher in both patient groups than in controls (P < 0.0001). Group 2 patients showed higher expression than group 3 (P < 0.0001). The Spearman's correlation coefficient showed in group 2 a positive correlation between MMP9 and TG2 expression (ρ = 0.437; P = 0.01), but no correlation in group 3 (ρ = 0.143; P = 0.45). Corticosteroid treatment significantly reduced MMP9 and TG2 expression in both groups, ameliorating symptoms and signs. A much higher percentage reduction was observed in SS. The pathogenic mechanisms of the 2 forms of dry eye give an account for the different MMP9 and TG2 expressions in the 2 groups of patients. The higher expression in SS is determined by the direct autoimmune insult to the ocular surface epithelia, whereas in MGD patients, with an epithelial damage due to an unbalanced tear secretion, the molecules expression is significantly lower, although higher than in controls.

    Full Text Available BACKGROUND Diabetes causes blindness in 20-74 year old persons. Blindness in diabetic patients may due to cataract or retinopathy. Dry eye is one of the ocular surface problem increasingly observed in diabetic patients. This study was performed to assess the prevalence of dry eye syndrome in type 2 diabetic patients and their contributing factors. MATERIALS AND METHODS A cross-sectional study was done between April 2016 to September 2016. 70 patients of type 2 diabetes diagnosed at Dr. Shankarrao Chavan Government Hospital, Nanded, were included in this study. Patients were assessed by questionnaire about other diseases and drugs. Dry eye syndrome was assessed with Tear Breakup Time (TBUT, Schirmer's test, lissamine green staining apart from routine ophthalmic examination. RESULTS Out of 60 patients, 32 (53% suffer from dry eye syndrome. CONCLUSION Diabetes and dry eyes appear to have a common association. Further studies need to be undertaken to establish an aetiologic relationship. As routine dilated fundus examination is an integral part of evaluation of diabetic patients in ophthalmic clinics, examination for dry eye should also be an integral part of the assessment of diabetic eye disease.

    Full Text Available AIM:To investigate the effect of sodium hyaluronate eye drops combined with vitamin A palmitate ophthalmic gel on levels of tear film stability and inflammatory cytokines in patients with dry eye. METHODS: A total of 100 patients with dry eye treated in our hospital from January 2015 to February 2017 were randomly divided into control group and observation group, 50 cases in each group. Patients in the control group were treated with sodium hyaluronate eye drops. Patients in the observation group were given vitamin A palmitate ophthalmic gel on the basis of the control group, and then the clinical efficacy, tear film stability and the level of inflammatory cytokines were detected in the two groups. RESULTS: After treatment, the levels of BUT and SⅠt in both groups increased significantly compared with that before treatment, and FL was significantly lower than that before treatment. The levels of BUT and SⅠt in the observation group after treatment were 11.24±0.22s and 11.4±0.17mm/5min respectively, which was high than that of control groups(PPPPCONCLUSION: Sodium hyaluronate eye drops combined with vitamin A palmitate ophthalmic gel can relieve the symptoms of patients with dry eye effectively, increase the stability of tear film, and reduce the levels of inflammatory factors in tears, which is reliable in clinical application.

    To evaluate the suitablity of commercially available moisture retention eyewear for treating evaporative dry eye. Eleven patients with evaporative dry eyes were prescibed moisture retention eyewear for 3 months in addition to regular lubricant eye drops. Frequency and severity of dry eye symptoms, corneal fluorescein staining and tear break up time (TBUT) were evaluated at baseline and 3-month post-treatment. Main outcome measure was global symptom score (based on severity and frequency of dry eye symptoms on a visual analog scale) and secondary outcomes were changes in sectoral corneal fluorescein staining and tear break up time (TBUT) from pre-treatment level. There was a significant improvement in dry eye symptoms after using moisture retention eyewear for 3 months (p eyes improved significantly (p dry eye symptoms in windy, air-conditioned environments or when doing vision-related daily tasks. This study shows that moisture retention eyewear might be a valuable adjunct in management of evaporative dry eye and this new design of commercially available eyewear could have a good acceptability rate.

    To evaluate corneal innervation and inflammatory cell infiltration using in vivo confocal microscopy (IVCM) and to correlate these findings with subjective symptoms of dry eye, as measured by the Ocular Surface Disease Index (OSDI) in patients with non-Sjögren's (NSDE) and Sjögren's syndrome dry eyes (SSDE). Central corneal images were prospectively captured from 10 age-matched healthy control eyes, 24 eyes with clinically diagnosed NSDE and 44 eyes with clinically diagnosed SSDE, using IVCM (HRT III RCM). Density, tortuosity and reflectivity of corneal nerves, presence of inflammatory dendritic cells (DCs) and OSDI scores were evaluated. Images obtained by IVCM from 78 eyes were analyzed. The density of nerve fibers was 1562 ± 996 μm/frame in the SSDE group, 2150 ± 1015 μm/frame in the NSDE group and 2725 ± 687 μm/frame in the control group (P eyes affected with NSDE and SSDE are characterized by alterations in corneal innervation and infiltration of inflammatory DCs. Corneal nerve density and reflectivity are correlated with severity of subjective dry eye symptoms, as measured by OSDI score.

    We investigated the benefits of a cognitive behavior therapy-based exercise program to reduce the dry eye symptoms of office workers. We recruited 11 office workers with dry eye symptoms, aged 31-64 years, who voluntarily participated in group health guidance at a manufacturing company. Participants learned about the role of physical activity and exercise in enhancing wellness and performed an exercise program at home 3 days per week for 10 weeks. We estimated the indexes of body composition, dry eye symptoms, and psychological distress using the Dry Eye-Related Quality of Life Score and the World Health Organization's Subjective Well-Being Inventory questionnaires pre- and postintervention. The 10-week exercise program and the questionnaires were completed by 48.1% (39 of 81) of the participants. Body composition did not change pre- and postintervention. However, the average of the Dry Eye-Related Quality of Life Score scores in participants with subjective dry eye significantly improved after the intervention. Moreover, the World Health Organization's Subjective Well-Being Inventory positive well-being score tended to increase after the intervention. In this study, we showed that a 10-week exercise program improved subjective dry eye symptoms of healthy office workers. Our study suggests that a cognitive behavior therapy-based exercise program can play an important role in the treatment of patients with dry eye disease.

    To investigate the expression of lipid peroxidation markers in the tear film and ocular surface and their correlation with disease severity in patients with dry eye disease. The concentrations of hexanoyl-lysine (HEL), 4-hydroxy-2-nonenal (HNE), and malondialdehyde (MDA) were measured with enzyme-linked immunosorbent assays in tears obtained from 44 patients with non-Sjogren syndrome dry eye and 33 control subjects. The correlations between the marker levels and the tear film and ocular surface parameters, including tear film break-up time (BUT), Schirmer tear value, tear clearance rate, keratoepitheliopathy scores, corneal sensitivity, conjunctival goblet cell density, and symptom score, were analyzed. The expression of the lipid peroxidation markers HEL, 4-HNE, and MDA in the conjunctiva was evaluated using immunohistochemistry. The concentrations of HEL, 4-HNE, and MDA were 279.84 ± 69.98 nmol/L, 0.02 ± 0.01 μg/mL, and 3.80 ± 1.05 pmol/mg in control subjects and 283.21 ± 89.67 nmol/L (p = 0.97), 0.20 ± 0.03 μg/mL (p dry eye patients. 4-HNE and MDA levels significantly correlated with BUT, Schirmer tear value, tear clearance rate, keratoepitheliopathy scores, conjunctival goblet cell density, and symptom score (p dry eye patients. The expression of late lipid peroxidation markers, 4-HNE and MDA, increases in the tear film and ocular surface of patients with dry eye. The levels correlate with various tear film and ocular surface parameters and may reflect the severity of dry eye disease.

    Full Text Available Aim : The aim of this study was to find out the prevalence of dry eye and evaluate personal and environmental risk factors attributable to dry eye in a hospital-based population. Materials and Methods : In this cross-sectional study, 1890 patients above 15 years of age were screened randomly for dry eye. McMonnies Dry Eye Questionnaire, Schirmer′s test, tear film breakup time (TBUT, presence of conjunctival injection, punctate epithelial erosions (PEE, and meibomian gland dysfunction (MGD were used to diagnose dry eye. Patient demographics including age, sex, smoking, and occupation and working environment were also recorded. Correlation of dry eye signs with symptoms and TFBUT and Schirmer′s tests was also assessed. Results : The prevalence of dry eye was 10.58%. The prevalence was higher in outdoor workers (17.77%. The male: female ratio was 2.33:1. The number of males was highest in the 56-60 (13% and 60-65 (14% years age groups while that of females was highest in the 46-50 (16.67% years age group. A total of 10% of the patients were smokers, while 8% were tobacco chewers. A 2.15-fold increase was found in the odds for dry eye in those exposed to excessive wind, 1.91-fold to sunlight exposure, and 2.04 for air pollution. Abnormally low TBUT and Schirmer′s tests were significantly associated with dry eye signs (P=0.009 and 0.014, respectively. Conclusion : Dry eye is a leading cause of ocular discomfort in OPD patients. Excessive exposure to wind, sunlight, high temperature, and air pollution was significantly related to dry eyes. There was a significant correlation between patient′s history, symptoms, dry eye signs and objective tests for tear film. The rural people and those with outdoor occupation are more exposed to extraneous influences of environmental factors in tropical climate. These factors affect the tear film and ocular surface causing the dry eye syndrome.

    To evaluate the effect of tear supplementation with preservative free 0.15% zinc-hyaluronate on ocular surface sensations and corneal sensitivity in dry eye patients. Ocular surface sensations were assessed using the ocular surface disease index (OSDI) questionnaire and by recording ocular sensations during forced blinking in parallel with noninvasive tear film breakup time measurement in 20 eyes of 20 dry eye patients. Corneal sensitivity thresholds to selective stimulation of corneal mechano-, thermal- and chemical receptors were measured using the Belmonte gas esthesiometer. All baseline measurements were repeated after 1 month of treatment with 0.15% zinc-hyaluronate. After 1 month, a significant decrease in mean OSDI score (from 35.66 ± 12.36 to 15.03 ± 11.22; P  0.05). Prolonged use of 0.15% zinc-hyaluronate results in an improvement of tear film stability and a decrease of dry eye complaints. The decrease in corneal mechano-and polymodal receptor excitability suggests that zinc-hyaluronate helps to recover normal corneal sensitivity, and thus might have a beneficial additional effect on reducing ocular surface complaints in dry eye patients.

    Contact lens induced dry eye affects approximately 50% of contact lens wearers. The aim was to assess the effects of Manuka (Leptospermum sp.) honey eye drops (Optimel, Melcare, Australia) on dry eye in contact lens wearers. The safety of the honey eye drops in contact lens wear and contact lens wearers' compliance were also evaluated. Prospective, randomised, cross over study, examiner masked, pilot treatment trial. Twenty-four participants aged 20 to 55 years with contact lens related dry eye were recruited and randomised to two treatment groups; 20 completed the study. One group used Optimel eye drops twice a day for two weeks followed by conventional lubricant (Systane Ultra, Alcon) therapy for two weeks; the other group completed the treatments in the reverse order. Before and after each treatment dry eye symptomology, ocular surface inflammation, and tear quantity and quality were assessed. Participants completed a daily log detailing their usage of treatments and any issues. Dry eye symptoms improved significantly after Optimel treatment. Patients with more severe symptoms at baseline showed a greater improvement in symptoms. No significant differences were observed in the objective signs of dry eye; presumably because of the short treatment duration. Seventy-five% of contact lens wearers reported good adherence to Optimel treatment and 95% reported no issues using this product. Optimel Eye Drops reduce the symptoms of dry eye in contact lens wearers and are safe to use. A longer treatment period to assess the effect on clinical signs of dry eye is required.

    With the understanding of the immune inflammatory response in the pathogenesis of dry eyes, and the limitations of widely used artificial tears and numerous pharmaceuticals and methods to promote tear secretion, clinicians pay more attention to the therapies that can promote tear secretion actively. Acupuncture treatment for dry eye may meet this requirement. To observe the clinical efficacy of acupuncture treatment on dry eye and the effects on duration, and to examine the mechanisms of acupuncture in treating patients with dye eyes. The study was performed at Department of Ophthalmology, Shuguang Hospital, Shanghai University of Traditional Chinese Medicine from August 2010 to May 2011. Patients with the primary diagnosis of dry eye were enrolled. Sixty-five patients were randomly divided into treatment group and control group, and were given 3 weeks of acupuncture treatment or artificial tear therapy respectively. The enzyme-linked immunosorbent assay was used to detect the lactoferrin content of the tears before and after treatment. In order to evaluate the efficacy of the treatment methods, the Schirmer I test and break-up time were also measured. Compared with before treatment, the lactoferrin content in the tears of patients in the treatment group increased, break-up time was prolonged and the result of the Schirmer I test showed improvement after 3 weeks of treatment. The indexes mentioned above did not change in the control group after treatment. There were no significant differences in tear lactoferrin and Schirmer I test between one week after treatment and after 3-week treatment in the treatment group, but break-up time was significantly shortened. The result of Schirmer I test in the treatment group was significantly higher than that in the control group one week after treatment. Acupuncture can increase tear lactoferrin level, extend tear film break-up time and promote tear secretion in patients with dry eye in a time-limited trial. With the end of

    To evaluate changes in the tear meniscus area and tear meniscus height over time in patients with dry eye syndrome, using anterior segment spectral-domain optical coherence tomography after the instillation of 3% diquafosol ophthalmic solution. Sixty eyes from 30 patients with mild to moderate dry eye syndrome were included. Tear meniscus images acquired by anterior segment spectral-domain optical coherence tomography were analyzed using National Institutes of Health's image-analysis software (ImageJ 1.44p). Tear meniscus area and tear meniscus height were measured at baseline, 5 minutes, 10 minutes, and 30 minutes after instillation of a drop of diquafosol in one eye and normal saline in the other eye. Changes in ocular surface disease index score, tear film break-up time, corneal staining score by Oxford schema, and meibomian expressibility were also evaluated at baseline, and after 1 week and 1 month of a diquafosol daily regimen. Sixty eyes from 30 subjects (mean age, 29.3 years; 8 men and 22 women) were included. In eyes receiving diquafosol, tear volume was increased at 5 and 10 minutes compared with baseline. It was also higher than saline instilled eyes at 5, 10, and 30 minutes. Changes in tear volume with respect to baseline were not statistically different after the use of diquafosol for 1 month. Ocular surface disease index score, tear film break-up time, and Oxford cornea stain score were significantly improved after 1 week and 1 month of daily diquafosol instillation, but meibomian expressibility did not change. Topical diquafosol ophthalmic solution effectively increased tear volume for up to 30 minutes, compared to normal saline in patients with dry eye syndrome. © 2017 The Korean Ophthalmological Society

    To evaluate the effects of diquafosol sodium ophthalmic solution 3% (DQS) and artificial tears (AT) on higher-order aberrations (HOAs) in patients with dry eye after cataract surgery. This was a post hoc analysis of a previously conducted randomized clinical study. Fifty-nine eyes from 42 patients (17 males and 25 females, aged 72.6±8.0 years) with verified or suspected dry eye at 4 weeks after cataract surgery were evaluated. The dry eye patients were randomly assigned to receive DQS or AT for 4 weeks. Tear breakup time (BUT), corneal and conjunctival fluorescein staining scores, and HOAs were analyzed before and after instillation. HOAs were measured consecutively for 10 seconds with a wavefront analyzer. Average HOAs, HOA fluctuations (fluctuation index [FI]) and changes in HOAs (stability index [SI]) were compared within and between the two groups. After 4 weeks of instillation, BUT significantly increased ( P =0.001) compared with preinstillation values in the DQS group, but not in the AT group. This increase in BUT in the DQS group was significantly greater than in the AT group ( P =0.014). Corneal and conjunctival fluorescein staining scores after instillation significantly improved compared with preinstillation values in the DQS group ( P =0.018). In HOAs, the cornea aberration changed from an upward curve (a sawtooth pattern) to an almost constant value (a stable pattern) in the DQS group, but not in the AT group. In FI and SI, there were no significant changes in either group; however, FI and SI were significantly lower in the DQS group than in the AT group (both, P =0.004). The dry eye patients after cataract surgery had a visual dysfunction in HOAs. DQS is effective to treat dry eye disease after cataract surgery with improvement of visual function.

    Dry eye is a common problem that affects many people worldwide, reducing quality of life and impacting daily activities. A qualitative approach often used in medicine and other disciplines is used to evaluate how people with dry eye cope with this impact. Six focus group sessions were conducted at the Singapore National Eye Centre (SNEC), premises of an eye research institute. These focus groups consist of a spectrum of dry eye sufferers (30 women, 8 men, aged 61 ± 11.8 years). Standard methods of coding followed by determination of themes were adhered to. Where classification was difficult, consensus was made between 3 assessors. Audio-recorded transcripts were coded in 10 themes by 3 assessors independently. Four of the themes involved traditional measures such as lid warming, cleansing, lubrication and oral dietary supplements. The other themes discovered were Traditional Chinese Medicine, modification of eye-care habits (e.g. wearing sunglasses), environmental humidity, lifestyle (e.g. sleeping habits), psychological attitude, and lastly sharing and communication. Holistic coping strategies were found to be prominent in dry eye sufferers from these focus groups, and people tend to find personalised ways of coping with the impact of dry eye on daily living.

Randomized controlled trial. setting: Soonchunhyang University Hospital, Seoul, South Korea. In all, 130 eyes of 86 dry eye patients who had undergone cataract surgery between January 2014 and January 2015 were enrolled and randomly divided into a diquafosol group and a sodium hyaluronate group. The diquafosol group used diquafosol 6 times a day and the hyaluronate group used sodium hyaluronate 6 times a day after cataract surgery. Evaluations of efficacy were conducted based on an Ocular Surface Disease Index questionnaire, tear breakup time (TBUT), Schirmer I test, corneal fluorescein and conjunctival lissamine green staining scores, serial measurement of ocular higher-order aberrations (HOAs), corneal HOAs, and uncorrected distance visual acuity test. Safety evaluations were based on anterior chamber inflammation and discontinuation of the eye drops. Objective signs and subjective symptoms were aggravated at 1 week postoperatively and began to recover significantly 4 weeks after surgery. The diquafosol group showed significantly superior TBUT (P < .001), corneal fluorescein (P = .045), and conjunctival staining (P = .001) compared to the sodium hyaluronate group throughout the study period. TBUT (P < .001) and the change in HOAs (P = .018) recovered significantly more quickly in the diquafosol group. The safety evaluations showed no intergroup differences. Eye drops of 3% diquafosol may be an effective and safe treatment for the management of cataract surgery-induced dry eye aggravation in patients with preexisting dry eye.

    Dry eye disease (DED) is a multifactorial disease of the ocular surface and is one of the most common reasons for patients to visit an eye care provider. Cyclosporine A (CsA) is an immune modulating drug that was approved in the US for topical use in the treatment of DED in 2003, which led to a paradigm change in our understanding and treatment of DED, turning attention to control of inflammation for treatment. This review summarizes the literature to date regarding the impact of CsA on the treatment of DED. A special focus is given to the patient and physician perspectives of CsA, including dry eye symptom improvement, medication side effects, and overall patient satisfaction. Studies evaluating CsA in DED have considerable heterogeneity making generalized conclusions about the effect of CsA difficult. However, most studies have demonstrated improvement in at least some symptoms of dry eye in CsA-treated patients. Side effects, most commonly ocular burning on administration of CsA, are common. The literature is sparse regarding long-term follow-up of patients treated with CsA, optimal duration of treatment, and identifying which patients may receive the most benefit from CsA.

Materials and methods: We recruited 11 office workers with dry eye symptoms, aged 31–64 years, who voluntarily participated in group health guidance at a manufacturing company. Participants learned about the role of physical activity and exercise in enhancing wellness and performed an exercise program at home 3 days per week for 10 weeks. We estimated the indexes of body composition, dry eye symptoms, and psychological distress using the Dry Eye-Related Quality of Life Score and the World Health Organization’s Subjective Well-Being Inventory questionnaires pre- and postintervention. Results: The 10-week exercise program and the questionnaires were completed by 48.1% (39 of 81 of the participants. Body composition did not change pre- and postintervention. However, the average of the Dry Eye-Related Quality of Life Score scores in participants with subjective dry eye significantly improved after the intervention. Moreover, the World Health Organization’s Subjective Well-Being Inventory positive well-being score tended to increase after the intervention. Conclusion: In this study, we showed that a 10-week exercise program improved subjective dry eye symptoms of healthy office workers. Our study suggests that a cognitive behavior therapy-based exercise program can play an important role in the treatment of patients with dry eye disease.

    Full Text Available Yasushi Inoue, Shintarou Ochi Inoue Eye Clinic, Tamano, Okayama, Japan Purpose: To evaluate the effects of diquafosol sodium ophthalmic solution 3% (DQS and artificial tears (AT on higher-order aberrations (HOAs in patients with dry eye after cataract surgery. Design: This was a post hoc analysis of a previously conducted randomized clinical study. Methods: Fifty-nine eyes from 42 patients (17 males and 25 females, aged 72.6±8.0 years with verified or suspected dry eye at 4 weeks after cataract surgery were evaluated. The dry eye patients were randomly assigned to receive DQS or AT for 4 weeks. Tear breakup time (BUT, corneal and conjunctival fluorescein staining scores, and HOAs were analyzed before and after instillation. HOAs were measured consecutively for 10 seconds with a wavefront analyzer. Average HOAs, HOA fluctuations (fluctuation index [FI] and changes in HOAs (stability index [SI] were compared within and between the two groups. Results: After 4 weeks of instillation, BUT significantly increased (P=0.001 compared with preinstillation values in the DQS group, but not in the AT group. This increase in BUT in the DQS group was significantly greater than in the AT group (P=0.014. Corneal and conjunctival fluorescein staining scores after instillation significantly improved compared with preinstillation values in the DQS group (P=0.018. In HOAs, the cornea aberration changed from an upward curve (a sawtooth pattern to an almost constant value (a stable pattern in the DQS group, but not in the AT group. In FI and SI, there were no significant changes in either group; however, FI and SI were significantly lower in the DQS group than in the AT group (both, P=0.004. Conclusion: The dry eye patients after cataract surgery had a visual dysfunction in HOAs. DQS is effective to treat dry eye disease after cataract surgery with improvement of visual function.

    There are limited data in the literature on the probability of dry-eye complications according to radiotherapy dose. This study investigates the risk of radiation-induced severe dry-eye syndrome in patients in whom an entire orbit was exposed to fractionated external beam irradiation. Between October 1964 and May 1989, 33 patients with extracranial head and neck tumors received irradiation of an entire orbit. Most patients were treated with 60 Co. The dose to the lacrimal apparatus was calculated at a depth of 1 cm from the anterior skin surface, the approximate depth of the major lacrimal gland. The end point of the study was severe dry-eye syndrome sufficient to produce visual loss secondary to corneal opacification, ulceration, or vascularization. Twenty patients developed severe dry-eye syndrome. All 17 patients who received dose ≥57Gy developed severe dry-eye syndrome. Three (19%) of 16 patients who received doses ≥45 Gy developed severe dry-eye syndrome; injuries in the latter group were much more slower to develop (4 to 11 years) than in the higher dose group, in whom corneal vascularization and opacification were usually pronounced within 9-10 months. There were no data for the range of doses between 45.01 and 56.99 Gy. The data did not suggest an increased risk of severe dry-eye syndrome with increasing age. Data from the current series and the literature are combined to construct a sigmoid dose response curve. The incidence of injury increases from 0% reported after doses ≥30 Gy to 100% after doses ≥57 Gy. 13 refs., 3 figs., 5 tabs

    Dry eye is a multi-factorial disorder that manifests with painful ocular symptoms and visual disturbances, which can only be partly attributed to tear dysfunction. This disorder may also involve neuroplasticity in response to neuronal injury. This review will emphasize the key characteristics of dry eye pain and its pathologic mechanisms, making the argument that a subset of dry eye represents a neuropathic pain disorder of the eye, more appropriately called "burning eye syndrome." A literature review was conducted using a PubMed search focusing on dry eye, corneal nociception, and neuropathic pain. Articles were reviewed and those discussing clinical course, pathophysiology, and neuronal regulation of chronic ocular pain as related to dry eye were summarized. We found that there is a discordance between ocular pain and dryness on the ocular surface. Although tear dysfunction may be one of the initial insults, its persistence may be associated with repeated ocular sensory nerve injury leading to an acute-to-chronic pain transition associated with neuropathologic changes (peripheral and central sensitization), neuronal dysfunction, and spontaneous ocular pain. Dry eye is becoming a major health concern due to its increasing incidence, significant morbidity, and economic burden. Recent evidence suggests that a subset of dry eye may be better represented as a chronic neuropathic pain disorder due to its features of dysesthesia, spontaneous pain, allodynia, and hyperalgesia. Future therapies targeted at the underlying neuroplasticity may yield improved efficacy for patients with this subset of dry eye, which we term "burning eye syndrome." © 2015 American Academy of Pain Medicine.

    Full Text Available Glaucoma is a common cause of irreversible blindness with increasing prevalence. Some of glaucoma patients will also experience dry eye. Dry eye is the most frequent side effect related to benzalkonium chloride (BAC-containing eye drop  used for glaucoma patients. In addition, glaucoma and dry eyes have shared risk factors that are old age and female. Dry eye among glaucoma patients need to be treated promptly as it produces discomfort, reduces patients’ compliance and   decreases success rate of glaucoma therapy. Dry eye symptoms can be treated by applying preservative-free eye drop, giving combination of preservative containing and preservative-free eye drop to reduce BAC exposure, prescribing artificial tear and conducting surgery to minimize or eliminate the need of topical medication.

    To investigate the long-term results of 3% diquafosol ophthalmic solution as an alternative therapy to existing ophthalmic solutions, including topical immunosuppression, for the treatment of dry eye in patients with Sjögren's syndrome. This study involved 14 female dry-eye patients (mean age: 62.4 years) with Sjögren's syndrome who insufficiently responded to their current therapy. In all patients, 3% diquafosol ophthalmic solution was administered six times daily for 12 months in substitution for artificial tears and sodium hyaluronate ophthalmic solution. Their use of corticosteroid eye drops remained unchanged from that prior to the treatment with diquafosol sodium. The subjective symptoms assessed, and ocular signs including tear meniscus radius and the tear film breakup time, and ocular-surface epithelial damage score were examined at 1, 2, 3, 4, 5, 6, 9, and 12 months after initiating treatment. Among the subjective symptoms, significant improvement was obtained in dryness at 2 months post treatment, in eye fatigue at 1, 2, 3, 4, and 12 months post treatment, and in pain at 1, 2, 6, and 12 months post treatment. Difficulty in opening the eye, foreign body sensation, and redness were also significantly ameliorated at various time-points. The tear meniscus radius and the tear film breakup time were significantly improved throughout the observation period, and the corneal epithelial staining scores were significantly decreased at 3 months post treatment. In dry-eye patients with Sjögren's syndrome, treatment with 3% diquafosol ophthalmic solution improved both symptoms and signs, and that effectiveness was maintained for 12 months.

    Dry eye is one of the most common complications occurring after laser-assisted in situ keratomileusis (LASIK), with virtually all patients experiencing some degree of postoperative dry eye symptoms. Enhanced understanding of the pathophysiology and mechanism of dry eye development in addition to preoperative screening of patients who are prone to dry eye is essential for better patient satisfaction and for improving short-term visual outcome postoperatively. This article reviews the latest studies published on LASIK-associated dry eye, including epidemiology, pathophysiology, risk factors, preoperative assessment, and management. PMID:29619255

    To assess the perceptions of eye care providers regarding the clinical management of dry eye. Invitations to complete a 17-question online survey were mailed to 400 members of the North Carolina Ophthalmology and Optometry Associations including community optometrists, comprehensive ophthalmologists, and cornea specialists. The survey was completed by 100 eye care providers (25% response rate). Providers reported burning (46.5%) as the most frequent symptom described by patients, followed by foreign body sensation (30.3%) and tearing (17.2%). Most respondents (80.8%) listed artificial tears as the recommended first-line treatment, even though providers reported high failure rates for both artificial tears and cyclosporine A (Restasis). Rheumatoid arthritis, Sjögren syndrome, affective disorders such as anxiety and depression, history of photorefractive surgery, smoking, and thyroid disease were acknowledged as common comorbid conditions. The survey provided an informative snapshot into the preferences of eye care providers concerning the diagnosis and management of dry eye disease. Overall, burning was the most common symptom reported by patients. Providers relied more on patient history in guiding their clinical decisions than objective signs. The survey underscores the incongruence when comparing subjective symptoms with objective signs, thereby highlighting the urgent need for the development of reliable metrics to better quantify dry eye symptoms and also the development of a more sensitive and specific test that can be used as the gold standard to diagnose dry eye.

    2-hydroxy estradiol (2-OHE2) is a catechol derivative of 17β -Estradiol (E2) and it is synthesized from E2 catalyzed by cytochrome P4501A1. Previous studies reported that 2-OHE2 is a physiologic antioxidant in lipoproteins, liver microsomes, and the brain. Catechol derivatives show an anti-inflammatory effect through the inhibition of prostaglandin endoperoxide synthase (PGS) activity. Corneal erosion caused by dry eye is related to an increase in oxidative stress and inflammation in ocular surface cells. We investigated the therapeutic effects of 2-OHE2 on corneal damage caused by dry eye. Steroidal radical scavenging activity was confirmed through the electron spin resonance (ESR) method. PGS activity was measured using the COX Fluorescent Activity Assay Kit. To evaluate the effect of 2-OHE2 on the treatment for dry eye, 2-OHE2 was applied as an eye drop experiment using dry eye model rats. 2-OHE2 scavenged tyrosyl radical and possibly suppressed oxidative stress in corneal epithelial cells. In addition, 2-OHE2 inhibited PGS activity, and 2-OHE2 is probably a competitive inhibitor of PGS. Corneal PGS activity was upregulated in the dry eye group. Therefore, 2-OHE2 eye drops improved corneal erosion in dry eye model rats. 2-OHE2 is a candidate for the treatment of dry eye through the suppression of inflammation and oxidative stress in the cornea.

    Dry eye syndrome is characterized by eye irritation due to changes of the tear film. Symptoms include itching, foreign body sensations, mucous discharge and transitory vision blurring. Less occurring symptoms include photophobia and eye tiredness. Aim of the work was to determine the quality of the tear film and ocular dryness potential risk in persons who spend more than 8 hours using computers and possible correlations between severity of symptoms (dry eyes symptoms anamnesis) and clinical signs assessed by: Schirmer test I, TBUT (Tears break-up time), TFT (Tear ferning test). The results show that subjects using computer have significantly shorter TBUT (less than 5 s for 56 % of subjects and less than 10 s for 37 % of subjects), TFT type II/III in 50 % of subjects and type III 31% of subjects was found when compared to computer non users (TFT type I and II was present in 85,71% of subjects). Visual display terminal use, more than 8 hours daily, has been identified as a significant risk factor for dry eye. It's been advised to all persons who spend substantial time using computers to use artificial tears drops in order to minimize the symptoms of dry eyes syndrome and prevents serious complications.

    Full Text Available Purpose. To evaluate the effectiveness and optical quality of 3.0% topical diquafosol versus 0.05% cyclosporine A in dry eye patients following cataract surgery. Methods. In total, 40 eyes of 40 patients newly diagnosed with dry eye syndrome 1 week after cataract surgery were randomized to receive either 3.0% diquafosol ophthalmic solution six times daily or 0.05% cyclosporine A twice daily for 3 months. Outcome measures were tear film break-up time (TBUT, results on Schirmer 1 test, ocular surface staining score, the ocular surface disease index (OSDI score, and higher-order aberrations (HOAs. Measurements were taken at baseline and at 1, 2, and 3 months. Results. In the diquafosol group, TBUT showed higher outcomes than the cyclosporine A group at 1 and 3 months. Both groups showed increased scores on Schirmer 1 test. The ocular surface staining score decreased in all periods in both groups. Vertical coma and total HOAs decreased more in the cyclosporine A group than in the diquafosol group at 3 months. Conclusion. Both 3.0% diquafosol and 0.05% cyclosporine A were effective in treating dry eye after cataract surgery. Diquafosol was more effective in increasing the tear secretion, but cyclosporine A was more effective in improving optical aberrations.

    To estimate the cost and patterns of expenditure of dry eye treatment. We retrieved data on the type and cost of dry eye treatment in Singapore National Eye Centre from pharmacy and clinic inventory databases over a 2 year period (2008-2009) retrospectively. According to the type of treatment, data were sorted into 7 groups; meibomien gland disease (MGD) treatment, preservative free lubricant eye drops, preserved lubricant eye drops, lubricant ointments and gels, cyclosporine eye drops, oral supplements and non-pharmacological treatments/procedures. Each recorded entry was considered as one patient episode (PE). Comparisons in each group between two years were carried out using Pearson Chi-Square test. Significance level was set at alpha  =  0.05. Cost data from 54,052 patients were available for analysis. Total number of recorded PEs was 132,758. Total annual expenditure on dry eye treatment for year 2008 and 2009 were US$1,509,372.20 and US$1,520,797.80 respectively. Total expenditure per PE in year 2008 and 2009 were US$22.11 and US$23.59 respectively. From 2008 to 2009, there was a 0.8% increase in total annual expenditure and 6.69% increase in expenditure per PE. Pharmacological treatment attributes to 99.2% of the total expenditure with lubricants accounting for 79.3% of the total pharmacological treatment expenditure. Total number of units purchased in preservative free lubricants, cyclosporine eye drops and MGD therapy have increased significantly (pDry eye imposes a significant direct burden to health care expenditure even without considering indirect costs. Health care planners should be aware that these direct costs appear to increase over the time and more so for particular types of medications. Given the limitations of socio-economic data, true societal costs of Dry eye syndrome are likely to be much higher than estimated.

    Full Text Available Prior studies suggested that glaucoma patients suffer worse dry eye and mood and sleep disorders than non-glaucoma subjects. Prostaglandin analogues are first-line therapy for glaucoma, inducing few instillation problems and sufficient pressure-reduction effects. This study compared dry eye, sleep quality, and mood status between glaucoma patients receiving prostaglandin monotherapy and non-glaucoma subjects.This cross-sectional study evaluated 1520 patients (579 males and 941 females for glaucoma status and dry eye-related symptoms (dryness, eye fatigue, photophobia, pain, blurring and signs (Schirmer test, tear break-up time, corneal staining scores. Of the total cohort, 93 patients were also evaluated by Pittsburgh sleep quality index (PSQI and hospital anxiety and depression score (HADS. Inclusion criteria were consecutive patients ≥ 51 years of age and best-corrected visual acuity ≥ 20/25. Glaucoma patients included those treated with prostaglandin or a fixed combination including prostaglandin. Exclusion criteria were history of ocular surgery within one month. Data were analyzed using the chi-square or Mann-Whitney U tests, at 5% significance.There were no significant differences in dry eye-related signs and symptoms between the control (n = 1431, mean age of 66.9 years and glaucoma groups (n = 89, 67.9 years. The psychiatric sub-analysis of the control (n = 61, 66.2 years and glaucoma groups (n = 32, 67.3 years revealed mean scores of 5.02 ± 3.10 and 5.16 ± 3.46 for PSQI (normal range ≤ 5, 9.47 ± 5.61 and 9.42 ± 7.36 for HADS (normal range ≤ 10, 4.84 ± 3.22 and 4.71 ± 3.45 for anxiety (normal range ≤ 5, and 4.63 ± 3.05 and 4.71 ± 4.40 for depression (normal range ≤ 5, respectively, without statistical significance.Our results were comparable between glaucoma patients on prostaglandin monotherapy and non-glaucoma subjects for dry eye-related clinical manifestations, sleep quality, and mood status.

    To survey ophthalmologists about current practice patterns regarding the evaluation of dry eye patients and referrals for a Sjogren syndrome (SS) workup. An online survey was sent to ophthalmologists affiliated with the Scheie Eye Institute or Wills Eye Hospital using REDCap in August 2015. Descriptive statistics were used to summarize the data. Four hundred seventy-four survey invitations were sent out and 101 (21%) ophthalmologists completed the survey. The common traditional dry eye test performed was corneal fluorescein staining (62%) and the most common newer dry eye test performed was tear osmolarity (18%). Half of respondents (51%) refer fewer than 5% of their dry eye patients for SS workups, with 18% reporting that they never refer any patients. The most common reasons for referrals included positive review of systems (60%), severe dry eye symptoms (51%) or ocular signs (47%), or dry eye that is refractory to treatment (42%). The majority (83%) felt that there is a need for an evidence-based standardized screening tool for dry eye patients to decide who should be referred for evaluation for SS. Ophthalmologists continue to prefer the use of traditional dry eye tests in practice, with the most common test being corneal fluorescein staining. There is an underreferral of dry eye patients for SS workups, which is contributing to the continued underdiagnosis of the disease. Most respondents felt that there was a need for an evidence-based standardized screening tool to decide which dry eye patients should be referred for SS evaluations.

    To assess the efficacy of an orally administered antioxidant dietary supplement for managing marginal dry eye. A prospective, randomised, placebo controlled trial with cross-over. Eye Clinic, Department of Vision Sciences, Glasgow Caledonian University. Forty marginal dry eye sufferers composed of 30 females and 10 males (median age 53 y; range 38-69 y). Baseline assessments were made of tear volume sufficiency (thread test), tear quality (stability), ocular surface status (conjunctival impression cytology) and dry eye symptoms (questionnaire). Each subject was administered courses of active treatment, placebo and no treatment, in random order for 1 month each and results compared to baseline. Tear stability and ocular surface status were significantly improved following active treatment (Ptreatment (P>0.05). Absolute increase in tear stability correlated with absolute change in goblet cell population density. Tear volume was not improved following any treatment period and dry eye symptom responses were subject to placebo effect. Oral antioxidants improved both tear stability and conjunctival health, although it is not yet understood whether increased ocular surface health mediates increased tear stability or vice versa. This study was supported by a PhD scholarship funded by the Department of Vision Sciences, Glasgow Caledonian University, Scotland. Antioxidant supplements and placebos were kindly donated by Vitabiotics.

We hypothesized that this more comprehensive approach would better discriminate between normal and dry eye subjects.Methods: Blinks were captured over 10 minutes for ten normal and ten dry eye subjects while viewing a standardized televised documentary. Fifty-five blinks were analyzed for each of the 20 subjects. Means, standard deviations, and autocorrelation coefficients were calculated utilizing a single random effects model fit to all data points and a diagnostic model was subsequently fit to predict probability of a subject having dry eye based on these parameters.Results: Mean IBI was 5.97 seconds for normal versus 2.56 seconds for dry eye subjects (ratio: 2.33, P = 0.004. IBI variability was 1.56 times higher in normal subjects (P < 0.001, and the autocorrelation was 1.79 times higher in normal subjects (P = 0.044. With regard to the diagnostic power of these measures, mean IBI was the best dry eye versus normal classifier using receiver operating characteristics (0.85 area under curve (AUC, followed by the standard deviation (0.75 AUC, and lastly, the autocorrelation (0.63 AUC. All three predictors combined had an AUC of 0.89. Based on this analysis, cutoffs of ≤3.05 seconds for median IBI, and ≤0.73 for the coefficient of variation were chosen to classify dry eye subjects.Conclusion: (1 IBI was significantly shorter for dry eye patients performing a visual task compared to normals; (2 there was a greater variability of interblink intervals in normal subjects; and (3 these parameters were useful as diagnostic predictors of dry eye disease.

    Dry eye is the second most common ocular disease. In China, the incidence rate of dry eye has reached 21% to 30%, and dry eye patients have accounted for more than 30% of the total ophthalmology outpatients. Dry eye has become a common health problem that affects the working efficiency and life quality of Chinese people. Over the past decade, due to the rapid development of diagnostic equipments and new treatments for dry eye, dry eye has become one of the areas with greatest concerns in ophthalmology, and many eye institutions have set up their dry eye clinics. Although the diagnosis and treatment of dry eye has been improved in recent years, the awareness of dry eye in Chinese ophthalmologists is still too simple. In the diagnosis, the interrogation and basic examination are not given enough attention, and we are over-relying on equipments. Clinical examination and instrument operation also have not been standardized. This article emphasizes that we should pay attention to the interrogation, basic examination and standardization of clinical examination and equipment operation in diagnosing dry eye. The treatment regimen should be mostly refined and optimized to be individualized and comprehensive based on the causes, types and severity of dry eye. In addition, the physical and adjuvant therapy of dry eye should be given sufficient attention and applied reasonably. (Chin J Ophthalmol, 2017, 53: 641-644) .

The clinical cost was 16,318 ± 9961 Japanese yen (165 ± 101 US dollars. The total direct costs including punctal plug treatment amounted to 52,467 ± 38,052 Japanese yen (530 ± 384 US dollars. Conclusion: Although treatment modalities for dry eye in Japan were different from those in the US and in European countries, the direct cost of dry eye patients in Japan was comparable with that reported in those countries. Considering the high prevalence of dry eye, the direct cost of this chronic condition may be significant.Keywords: burden of disease, cost, dry eye, eyedrops, quality of life

    Lifitegrast is a novel small molecule integrin antagonist that blocks the binding of intercellular adhesion molecule 1 (ICAM-1) to lymphocyte function-associated antigen 1 (LFA-1). Lifitegrast ophthalmic solution 5% (Xiidra™) was recently approved in the USA for the treatment of dry eye disease. The efficacy of lifitegrast ophthalmic solution 5% was compared with vehicle in a 12-week phase 2 study and three 12-week phase 3 studies (OPUS-1, OPUS-2 and OPUS-3) in patients with dry eye disease. Taken as a whole, results of these trials support the treatment effect of lifitegrast ophthalmic solution 5% in improving a symptom of dry eye disease (i.e. the change from baseline to day 84 in the eye dryness visual analogue scale score) and a sign of dry eye disease (i.e. the change from baseline to day 84 in the inferior corneal fluorescein staining score). Lifitegrast ophthalmic solution 5% was generally well tolerated. In conclusion, lifitegrast ophthalmic solution 5% provides a new option for the treatment of dry eye disease.

    Conducted a comparative analysis of functional changes in tear production in patients with dry eye syndrome and endocrine ophthalmopathy in the conditions of the long-term acting of preservative free medications based on natural substances. A total of 30 people, aged 35 to 53 years old with clinical manifestations of DES on the background of EO were divided on two groups. In I group eye drops of ectoine and in II - artificial tears were administered. The examination included general and specific methods. The term of follow up - 30 days. It was found that long-term use of preservative free eye drops based on ectoine leads to more expressive positive changes in the condition of the anterior surface of the eye and the secretion and quality of the tear.

    Diquafosol ophthalmic solution 3 % (Diquas(®)) is a P2Y2 receptor agonist that promotes tear fluid and mucin secretion and is currently approved in Japan and South Korea for the treatment of dry eye. In randomized, double-blind, multicentre trials in patients with dry eye, significantly greater improvements in fluorescein and rose bengal staining scores were seen with diquafosol ophthalmic solution 3 % than with placebo, and diquafosol ophthalmic solution 3 % was noninferior to sodium hyaluronate ophthalmic solution 0.1 % in terms of the improvement in the fluorescein staining score and more effective than sodium hyaluronate ophthalmic solution 0.1 % in terms of the improvement in the rose bengal staining score. The efficacy of diquafosol ophthalmic solution 3 % in the treatment of dry eye was maintained in the longer term, with improvements also seen in subjective dry eye symptoms, and was also shown in a real-world setting. Diquafosol ophthalmic solution 3 % also demonstrated efficacy in various specific dry eye disorders, including aqueous-deficient dry eye, short tear film break-up time dry eye, obstructive meibomian gland dysfunction, dry eye following laser in situ keratomileusis surgery and dry eye following cataract surgery, as well as in contact lens wearers and visual display terminal users. Diquafosol ophthalmic solution 3 % was generally well tolerated in patients with dry eye, with eye irritation the most commonly reported adverse event. In conclusion, diquafosol ophthalmic solution 3 % is a useful option for the treatment of dry eye.

    IL-21 plays an important role in primary Sjögren syndrome (SS) pathogenesis. The purpose of this study was to evaluate IL-21 expression in tears and the conjunctiva and to analyze the impact of IL-21 on primary SS dry eyes. Eighty subjects were enrolled in this study: 30 patients with primary SS dry eye (30 eyes); 30 patients with non-SS dry eye (30 eyes), and 20 normal controls. Tear IL-21 levels were measured by flow cytometry, and IL-21 gene expression in the conjunctiva from impression cytology was evaluated by quantitative polymerase chain reaction. Ocular Surface Disease Index, tear film breakup time, Schirmer I test, and ocular surface staining scores were obtained for all patients. Primary SS dry eyes had significantly higher tear IL-21 levels than non-SS dry eyes and normal controls (P dry eyes than in non-SS dry eyes and normal controls (P dry eyes and controls. The tear IL-21 level was significantly correlated with ocular surface stain scores (r = 0.54, P dry eyes. Our findings suggest that severity of primary SS dry eye is associated with IL-21.

    To evaluate the immunomodulatory effect of topical ophthalmic tofacitinib (CP-690,550) after an 8-week treatment period in patients with dry eye disease (DED). Biomarker substudy of a phase 1/2 prospective, randomized, vehicle- and comparator-controlled clinical trial (NCT00784719). A total of 82 patients with moderate to severe DED enrolled. Patients received 1 of 5 doses of tofacitinib (0.0003%, 0.001%, 0.003%, or 0.005% twice daily [BID] or 0.005% once daily [QD]), active comparator (cyclosporine ophthalmic emulsion, 0.05% [Restasis, Allergan Inc., Irvine, CA]), or vehicle control BID for 8 weeks. Conjunctival impression cytology and tear fluid samples were collected at baseline and after an 8-week treatment period. Conjunctival cells were analyzed by flow cytometry for human leukocyte antigen DR-1 (HLA-DR). Tear fluids were analyzed by microsphere-based immunoassays for tear levels of cytokines and inflammation markers. Reduction in inflammation assessed by change from baseline in conjunctival cell surface level of HLA-DR and tear level of cytokines and inflammation markers. At week 8, a decrease in conjunctival cell surface expression of HLA-DR was observed in patients treated with tofacitinib 0.005% QD and 0.003% BID: 71% and 67% of baseline, respectively, compared with 133% of baseline in patients treated with vehicle (P=0.023 and P=0.006, compared with vehicle, respectively). Matrix metalloproteinase (MMP)-3 in tears was reduced from baseline at week 8 (40% of baseline, P=0.035) in the tofacitinib 0.005% QD group, whereas the vehicle group showed 77% of baseline (P>0.20). Interleukin (IL)-1β in tears was 36% of baseline (P=0.053) in the tofacitinib 0.005% QD group and 95% of baseline (P > 0.20) in the vehicle group. Several other cytokines and inflammation markers in tears, including MMP-9, IL-15, IL-17A, and IL-12p70, were markedly reduced in the tofacitinib 0.005% QD group but not the vehicle group.

    The objectives of this study were to develop stable cyclosporine A (CsA) ophthalmic micelle solutions for dry-eye syndrome and evaluate their physicochemical properties and therapeutic efficacy. CsA-micelle solutions (MS-CsA) were created by a simple method with Cremophor EL, ethanol, and phosphate buffer. We investigated the particle size, pH, and osmolarity. In addition, long-term physical and chemical stability for MS-CsA was observed. To confirm the therapeutic efficacy, tear production in dry eye-induced rabbits was evaluated using the Schirmer tear test (STT). When compared to a commercial product, Restasis, MS-CsA demonstrated improvement in goblet-cell density and conjunctival epithelial morphology, as demonstrated in histological hematoxylin and eosin staining. MS-CsA had a smaller particle size (average diameter 14-18 nm) and a narrow size distribution. Physicochemical parameters, such as particle size, pH, osmolarity, and remaining CsA concentration were all within the expected range of 60 days. STT scores significantly improved in MS-CsA treated groups (Pdry eye-induced rabbits thinned with loss of goblet cells. However, after 5 days of treatment with drug formulations, rabbit conjunctivas recovered epithelia and showed a relative increase in the number of goblet cells. The results of this study indicate the potential use of a novel MS for the ophthalmic delivery of CsA in treating dry eyes.

    This study evaluates the efficacy of 3% diquafosol tetrasodium ophthalmic solution in Sjögren's syndrome (SS) and non-SS dry eye patients unresponsive to conventional artificial tear. This retrospective study included 38 dry eye patients (11 with SS and 27 with non-SS) who were treated with 3% diquafosol due to lack of response to artificial tear treatment for more than 3 months. Signs such as tear film break-up time (TBUT), Schirmer-I test, and total ocular staining score (OSS), which consisted of corneal OSS and conjunctival OSS, were evaluated at baseline and the first visit after treatment. Symptoms were quantified using visual analog scale (VAS) and ocular surface disease index (OSDI) scores. Changes of parameters after treatment in all the patients and differences of changes in SS and non-SS were evaluated. In total population, total OSS and corneal OSS improved average 6 weeks after diquafosol treatment (all P < 0.05, paired t-test), although conjunctival OSS had no improvement. TBUT increased after treatment (P = 0.036), while Schirmer-I test, OSDI, and VAS showed no improvement. With respect to comparisons, total and corneal OSS improved in non-SS patients and TBUT improved in SS patients (all P < 0.05). Three percent diquafosol tetrasodium treatment could be considered as an additive or substitute treatment when artificial tear treatment is insufficient, as it improved OSS and TBUT. This study also demonstrated that diquafosol treatment is beneficial for TBUT improvement in SS, while it is beneficial for OSS improvement in non-SS dry eye patients.

    Dry eye is one of the most common ocular problems in ophthalmology clinic. With the change of social environment and people's life style, the prevalence of dry eye disease is increasing. Currently, the diagnosis criteria for dry eye is controversial, diagnosis of dry eye mainly rely on the comprehensive assessment of symptoms and the presence of associated ocular surface signs. However, previous studies have shown a poor correlation between dry eye symptoms and objective clinical signs in patients. Recent studies have found that neuropathic pain plays an important role in the occurrence of discordance between symptoms and signs in dry eye disease. The purpose of this paper is to present the conception of pain, the distribution and function of sensory nerves in ocular surface, the prevalence and mechanism of neuropathic pain and analgesic treatment in dry eye disease.

    To study the efficacy of epiretinal membrane (ERM) peeling in eyes with dry age-related macular degeneration (AMD). We retrospectively analyzed patient charts on 17 eyes (16 patients) that underwent ERM peeling with a concurrent diagnosis of dry AMD. Eyes with concurrent dry AMD and with a good preoperative best-corrected visual acuity (BCVA) (better than or equal to 20/50) had a statistically significant mean BCVA improvement at 6 months after ERM peeling. There was a statistical increase in mean BCVA from 20/95 to 20/56 in dry AMD eyes, and no eyes showed worsening in BCVA at 6 months or at most recent follow-up. Five/seventeen (29.4%) eyes had cataract formation or progression. There were no other complications, reoperations, or reoccurrences. ERM peeling in eyes with dry AMD may show significant improvement, especially in eyes with good preoperative BCVA. The procedure is relatively safe with low complications and reoccurrences.

    2013-01-01

    Dry eye is a common ocular surface inflammatory disease that significantly affects quality of life. Dysfunction of the lacrimal function unit (LFU) alters tear composition and breaks ocular surface homeostasis, facilitating chronic inflammation and tissue damage. Accordingly, the most effective treatments to date are geared towards reducing inflammation and restoring normal tear film. The pathogenic role of CD4+ T cells is well known, and the field is rapidly realizing the complexity of other innate and adaptive immune factors involved in the development and progression of disease. The data support the hypothesis that dry eye is a localized autoimmune disease originating from an imbalance in the protective immunoregulatory and proinflammatory pathways of the ocular surface.

    To evaluate the efficacy of plasma rich in growth factors (PRGF) for the treatment of moderate/severe dry eye. PRGF treatment was administered to 16 patients who had moderate/severe dry eye diagnosed and who had not responded previously to other standard treatments. We quantified several growth factors present in the PRGF of each patient and obtained quantitative registers of the symptoms (modified score dry eye questionnaire), both before and after PRGF treatment. We also performed impression cytology to determine the degree of squamous metaplasia before and after PRGF treatment. PRGF treatment was associated with a statistically significant improvement in score dry eye questionnaire values (P PRGF, no further treatments were required, whereas in the remaining 25% other ocular treatments could be reduced. PRGF led to symptom improvement in patients with moderate/severe dry eye. Surprisingly, the symptoms recorded in the dry eye questionnaire do not always agree with the degree of squamous metaplasia measured by impression cytology.

    Evaporative dry eye disease is one of the most common types of dry eye. It is often the result of chronic meibomian gland dysfunction (MGD) and associated ocular rosacea. Evaporative dry eye and MGD significantly reduce patient's quality of life. Traditional treatments, such as artificial tears, warm compresses, and medications, such as topical cyclosporine, azithromycin, and oral doxycycline, provide some relief; however, many patients still suffer from dry eye symptoms. Intense pulsed light (IPL) therapy, which has been used extensively in dermatology to treat chronic skin conditions, is a relatively new treatment in ophthalmology for patients with evaporative dry eye disease. There are very few studies published on the use of IPL in patients with dry eye disease. The present review describes the theoretical mechanisms of IPL treatment of MGD and ocular rosacea. Personal clinical experience and recently presented data are reported as well. IPL therapy has promising results for evaporative dry eye patients. There are statistically significant improvements in clinical exam findings of dry eye disease. More importantly, patients report subjective improvement in their symptoms. More research is needed in this area to help understand the mechanism of dry eye disease and how it can be effectively treated.

    To evaluate the efficacy and safety of two ophthalmic solutions in patients with mild to moderate dry eye. We performed a prospective, 2-month-long, randomized, double-blind, single-center, parallel clinical trial to compare the efficacy and safety of two ophthalmic solutions for dry eye treatment. Patients were randomly assigned to one of the two treatment groups, study group or active-control group, and received one drop four times a day. The primary efficacy endpoint was to extend the tear film break-up time (TBUT) after 2 months of treatment. The Ocular Surface Disease Index (OSDI) was also evaluated. Safety measures were assessed by the presence of adverse events. A total of 28 patients with mild to moderate dry eye were included in the per protocol analysis. TBUT was similar between groups at baseline (chondroitin sulfate and xanthan gum [CS/XG] group, 5.2 ± 2.3; Systane(®) group, 4.7 ± 2.6; P = 0.488), after 2 months of treatment, TBUT was still similar in both groups (CS/XG group, 6.1 ± 2.5; Systane(®) group, 7.3 ± 2.5; P = 0.088). Baseline OSDI was similar between the groups (CS/XG group, 18.8 ± 5.3; Systane(®) group, 19.8 ± 7.1; P = 0.810), but after 2 months of treatment, the OSDI was significantly lower in the CS/XG group (6.7 ± 5.7 versus 10.8 ± 6.4; P = 0.049). An adverse event was present in the CS/XG group, but it was not related to the treatment. In this population of patients with mild to moderate dry eye, treatment with CS/XG was as effective as treatment with Systane(®) with regard to TBUT; nevertheless, treatment in the CS/XG group was more effective at diminishing OSDI.

    To evaluate dry eye tests and meibography of patients with pseudophakic bullous keratopathy (PBK). Thirty-seven patients with PBK were included. The eyes with PBK were compared with the normal pseudophakic fellow eyes. All patients had undergone a detailed ophthalmic examination including corneal and conjunctival fluorescein staining and Oxford scoring, tear film breakup time, Schirmer 1 test, Ocular Surface Disease Index (OSDI) score assessment, lid margin abnormalities, upper and lower eyelid Meibomian gland evaluation using infrared captures of a biomicroscope. Partial or complete loss of the Meibomian glands (Meibomian dropout) was scored for each eyelid from grade 0 (no loss) through grade 3 (lost area was > 2/3 of the total meibomian gland area). The mean age of the patients was 73.2 ± 8.9 (range, 50-93). Mean tear film breakup time value was statistically lower in PBK eyes (P ≤ 0.001). OSDI, Oxford, lid margin abnormalities, inferior meibography, total meibography score were significantly higher in PBK eyes (P ≤ 0.001). The comparison of Schirmer 1 and superior meibography scores of the groups was insignificant (P = 0.143, P = 0.793, respectively). The Meibomian gland morphology of the PBK eyes demonstrates significant differences when compared with normal fellow eyes and might be related to evaporative dry eye. For this reason, patients with PBK should be monitored for Meibomian gland dysfunction and when needed start prompt treatment in order to prevent further disturbance of the ocular surface.

    Full Text Available OBJECTIVES: To estimate the cost and patterns of expenditure of dry eye treatment. METHODOLOGY: We retrieved data on the type and cost of dry eye treatment in Singapore National Eye Centre from pharmacy and clinic inventory databases over a 2 year period (2008-2009 retrospectively. According to the type of treatment, data were sorted into 7 groups; meibomien gland disease (MGD treatment, preservative free lubricant eye drops, preserved lubricant eye drops, lubricant ointments and gels, cyclosporine eye drops, oral supplements and non-pharmacological treatments/procedures. Each recorded entry was considered as one patient episode (PE. Comparisons in each group between two years were carried out using Pearson Chi-Square test. Significance level was set at alpha  =  0.05. RESULTS: Cost data from 54,052 patients were available for analysis. Total number of recorded PEs was 132,758. Total annual expenditure on dry eye treatment for year 2008 and 2009 were US$1,509,372.20 and US$1,520,797.80 respectively. Total expenditure per PE in year 2008 and 2009 were US$22.11 and US$23.59 respectively. From 2008 to 2009, there was a 0.8% increase in total annual expenditure and 6.69% increase in expenditure per PE. Pharmacological treatment attributes to 99.2% of the total expenditure with lubricants accounting for 79.3% of the total pharmacological treatment expenditure. Total number of units purchased in preservative free lubricants, cyclosporine eye drops and MGD therapy have increased significantly (p<0.001 whereas number of units purchased in preserved lubricants and ointments/gels have reduced significantly (p<0.001 from 2008 to 2009. CONCLUSION: Dry eye imposes a significant direct burden to health care expenditure even without considering indirect costs. Health care planners should be aware that these direct costs appear to increase over the time and more so for particular types of medications. Given the limitations of socio-economic data, true

    To evaluate the effect of excess meibum on tear evaporation rate in patients with and without dry eye. Eleven healthy subjects and 16 patients with dry eye were tested. The dry eye group was divided into 2 subgroups: classic keratoconjunctivitis sicca (KCS) with clear and easily expressed meibum and KCS with meibomian gland dysfunction (MGD) with turbid secretions and difficult-to-express meibum. Evaporative measurements were performed at baseline and after digital expression of meibomian glands at 12, 24, 36, and 48 minutes. Two ranges of relative humidity were used, 25% to 35% and 35% to 45%. The data were expressed as microliters per square centimeter per minute. An increase in the evaporation rate of the tear film was noted for all measurements at both relative humidities in the classic KCS and KCS with MGD groups compared with healthy subjects (P evaporation rates at relative humidities of 25% to 35% and 35% to 45% were 0.056 ± 0.016 and 0.040 ± 0.008 for the classic KCS group; 0.055 ± 0.026 and 0.037 ± 0.019 for the KCS with MGD group and 0.033 ± 0.012 and 0.023 ± 0.008 for the healthy group. Also, a decrease in the evaporation rate was observed in the healthy and KCS with MGD groups between baseline and the first measurement after digital expression for both relative humidities (P evaporation rates compared with the healthy group. Aqueous tear evaporation diminished in the healthy and KCS with MGD groups after expression of meibomian glands. However, this effect was transient and negligible after the second measurement.

    Full Text Available Abstract Background Dry eye disease is a common debilitating ocular disease. Current diagnostic tests used in dry eye disease are often neither sensitive nor reproducible, making it difficult to accurately diagnose and determine end points for clinical trials, or evaluate the usefulness of different medications in the treatment of dry eye disease. The recently developed fluorophotometer can objectively detect changes in the corneal epithelium by quantitatively measuring its barrier function or permeability. The purpose of the study is to investigate the use of corneal fluorescein penetration measured by the fluorophotometer as a diagnostic tool in the evaluation of dry eye patients. Methods Dry eye patients (16 eyes, who presented with a chief complaint of ocular irritation corresponding with dry eye, low Schirmer's one test ( Results Ten minutes after fluorescein installition, patients with dry eye disease averaged a five-fold increase in corneal tissue fluorescein concentration (mean = 375.26 ± 202.67 ng/ml compared with that of normal subjects (mean = 128.19 ± 85.84 ng/ml. Sixty minutes after dye installation, patients with dry eye disease still revealed higher corneal tissue fluorescein concentration (mean = 112.87 ± 52.83 ng/ml compared with that of controls (mean = 40.64 ± 7.96 ng/ml, averaging a three-fold increase. Conclusion Patients with dry eye disease demonstrated an increased corneal permeability and a slower rate of elimination to topically administered fluorescein when measured by the fluorophotometer. This suggests that fluorophotometry may serve as a valuable quantitative and objective tool for the diagnosis of dry eye disease, and in following patients' response to new treatment modalities. Fluorophotometry may serve as an objective non-invasive tool for end-point analysis in clinical trials of new treatments for dry eye disease.

    To evaluate the 1-year safety of lifitegrast ophthalmic solution 5.0% in patients with dry eye disease compared with placebo. SONATA (Safety Of a 5.0% coNcentrATion of lifitegrAst ophthalmic solution) was a multicenter, randomized, prospective, double-masked, placebo-controlled phase 3 study (NCT01636206). Adults (≥18 years) with dry eye disease (Schirmer test score ≥1 and ≤10 mm; corneal staining score ≥2.0) were randomized 2:1 to lifitegrast ophthalmic solution 5.0% or placebo twice daily for 360 days. The primary objective was percentage and severity of treatment-emergent adverse events (TEAEs). Secondary objectives were ocular safety measures: corneal fluorescein staining, drop comfort, best-corrected visual acuity, slit-lamp biomicroscopy, and intraocular pressure over 7 visits. Exploratory objectives included concentration of lifitegrast in plasma. The safety population comprised 331 participants (220 lifitegrast; 111 placebo). There were no serious ocular TEAEs. Overall, 53.6% of participants receiving lifitegrast experienced ≥1 ocular TEAE versus 34.2% in the placebo group; most TEAEs were mild to moderate in severity. Rates of discontinuation because of TEAEs were 12.3% (lifitegrast) versus 9.0% (placebo). The most common (>5%) TEAEs occurring in either treatment group were instillation site irritation (burning), instillation site reaction, visual acuity reduced, dry eye, and dysgeusia (change in taste). Ocular safety parameters for lifitegrast were similar to placebo. The mean plasma lifitegrast concentration at 360 days (n = 43) was below the limit of detection. There was no indication of systemic toxicity or localized infectious complications secondary to chronic immunosuppression. Lifitegrast ophthalmic solution 5.0% seemed safe and well tolerated in this study, with no unexpected adverse events.

    To investigate whether suppression of blue light can improve visual function in patients with short tear break up time (BUT) dry eye (DE). Twenty-two patients with short BUT DE (10 men, 12 women; mean age, 32.4 ± 6.4 years; age range, 23-43 years) and 18 healthy controls (10 men, 8 women; mean age, 30.1 ± 7.4 years; age range, 20-49 years) underwent functional visual acuity (VA) examinations with and without wearing eyeglasses with 50% blue light blocked lenses. The functional VA parameters were starting VA, functional VA, and visual maintenance ratio. The baseline mean values (logarithm of the minimum angle of resolution, logMAR) of functional VA and the visual maintenance ratio were significantly worse in the DE patients than in the controls (P 0.05). The DE patients had significant improvement in mean functional VA and visual maintenance ratio while wearing the glasses (P 0.05). Protecting the eyes from short-wavelength blue light may help to ameliorate visual impairment associated with tear instability in patients with DE. This finding represents a new concept, which is that the blue light exposure might be harmful to visual function in patients with short BUT DE.

    Dry eye syndrome is a disorder of the tear film that is associated with symptoms of ocular discomfort. Punctal occlusion is a mechanical treatment that blocks the tear drainage system in order to aid in the preservation of natural tears on the ocular surface. To assess the effects of punctal plugs versus no punctal plugs, different types of punctal plugs, and other interventions for managing dry eye. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (which contains the Cochrane Eyes and Vision Trials Register) (2016, Issue 11), MEDLINE Ovid (1946 to 8 December 2016), Embase.com (1947 to 8 December 2016), PubMed (1948 to 8 December 2016), LILACS (Latin American and Caribbean Health Sciences Literature Database) (1982 to 8 December 2016), the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com; last searched 18 November 2012 - this resource is now archived), ClinicalTrials.gov (www.clinicaltrials.gov; searched 8 December 2016), and the WHO International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en; searched 8 December 2016). We did not use any date or language restrictions in the electronic searches for trials. We also searched the Science Citation Index-Expanded database and reference lists of included studies. The evidence was last updated on 8 December 2016 SELECTION CRITERIA: We included randomized and quasi-randomized controlled trials of collagen or silicone punctal plugs in symptomatic participants diagnosed with aqueous tear deficiency or dry eye syndrome.

    Clinical patterns in pediatric patients with dry eye syndrome and allergic conjunctivitis were investigated. Children aged 6 to 15 years with dry eye symptoms were included. Slit-lamp examinations including tear film break-up time, Schirmer's test, and fluorescent staining were performed, and subjective symptoms were investigated. Patients with allergic conjunctivitis were subjected to skin prick tests. Tear film break-up time was shorter and the number of symptoms related to dry eyes was higher in pediatric patients with allergic conjunctivitis than in those without allergic conjunctivitis. Patients with allergic conjunctivitis who had higher numbers of positive allergens on the skin prick test also had shorter tear film break-up time. Because pediatric patients with dry eye syndrome tend to complain less about their symptoms than adult patients, dry eye syndrome is commonly overlooked. This study showed that dry eyes tended to be more severe with the presence of allergic conjunctivitis; the more allergens present, the more severe the dry eyes. More attention should be paid to the treatment of pediatric patients with dry eyes accompanied by allergies. Copyright 2013, SLACK Incorporated.

    Full Text Available Abstract Background Dry eye is usually managed by conventional medical interventions such as artificial tears, anti-inflammatory drugs and surgical treatment. However, since dry eye is one of the most frequent ophthalmologic disorders, safer and more effective methods for its treatment are necessary, especially for vulnerable patients. Acupuncture has been widely used to treat patients with dry eye. Our aim is to evaluate the effectiveness and safety of acupuncture for this condition. Methods/Design A randomised, patient-assessor blinded, sham (non-acupuncture point, shallow acupuncture controlled study was established. Participants allocated to verum acupuncture and sham acupuncture groups will be treated three times weekly for three weeks for a total of nine sessions per participant. Seventeen points (GV23; bilateral BL2, GB4, TE23, Ex1 (Taiyang, ST1 and GB20; and left SP3, LU9, LU10 and HT8 for men, right for women have been selected for the verum acupuncture; for the sham acupuncture, points have been selected that do not coincide with a classical acupuncture point and that are located close to the verum points, except in the case of the rim of the eye. Ocular surface disease index, tear film breakup time, the Schirmer I test, medication quantification scale and general assessment of improvement will be used as outcome variables for evaluating the effectiveness of acupuncture. Safety will also be assessed at every visit. Primary and secondary outcomes will be assessed four weeks after screening. All statistical analyses will be performed using analysis of covariance. Discussion The results of this trial will be used as a basis for clarifying the efficacy of acupuncture for dry eye. Trial registration ClinicalTrials.gov NCT00969280.

    Tear instability is associated with symptoms of ocular discomfort and irritation. Many patients with dry eyes remain untreated due to improper diagnoses. To identify symptoms and surface abnormalities associated with dry eyes. One hundred and fifty-six eyes of 78 subjects attending the Eye Clinic of the University College Hospital Ibadan were screened for dry eyes/tear instability using rose Bengal stain (graded 0-9), tear break-up time (TBUT), Schirmer's 1 tests, tear meniscus height and a standardised symptoms questionnaire. Grades 4-9 rose Bengal staining were considered as positive dry eye and were compared with grades 0-3 staining eyes as negative controls. Mean tear meniscus height, Schirmer's test and TBUT were lower among cases than their corresponding control eyes. The difference between the mean Schirmer's test values of cases and their controls were statistically significant (P = 0.00 for right eyes and P = 0.002 for left eyes). Rose Bengal grades were inversely correlated with the mean Schirmer's values (Pearson correlation -0.429, P = 0.05 for right eyes and -0.335, P = 0.03 for left eyes) and TBUT (Pearson correlation -0.316, P = 0.05 for right eyes and -0.212, P = 0.06 for left eyes). About 95.8% of the cases were symptomatic, as opposed to 70.4% of the controls (P = 0.01, Fisher's exact test) and 95.8% of dry right eyes compared to 61.1% of their controls had ocular surface abnormalities (P = 0.001), while 89.5% of dry left eyes compared to 62.7% of controls had surface abnormalities (P = 0.07). A close relationship exists between ocular irritation symptoms, surface abnormalities and functional evidence of tear instability. Such patients should be treated empirically or screened for dry eyes.

    Objective Dry eye is a prevalent condition with significant socioeconomic burden. This study evaluates the extent and reasons for loss to follow-up (LTF) in a dedicated dry eye clinic. LTF refers to patient who discontinued visits for >2 years. Method The proportion of patients LTF and the demographics in a cohort of dry eye patients (2006 to 2010) were determined. A telephone survey was prospectively conducted for patients who were LTF. Results Of 505 patients, 240 (47.5%) were LTF. Associated demographic factors for LTF were male sex, non-Chinese ethnicity, and age group dry eye condition (47%), personal/social factors (25%) and perceived insufficiency of healthcare delivery (28%). Only two (1.1%) were considered as management failures. The younger patients (age dry eye disease, compared to older patients who were more likely to be LTF due to personal/social reasons (P=0.02). Poor communication and service factors under healthcare delivery were found to be higher (P=0.002) in those who visited once before they were LTF (8.5%) compared to those who visited multiple times before they were LTF (0.1%). Conclusion LTF was relatively common in hospital-based dry eye management. Female and older patients were less likely to stop consultation. Stabilized dry eye condition, common in younger patients, was the most common reason for LTF. Elderly patients have difficulty attending clinics due to nonmedical problems, which may require a more holistic approach. PMID:25336929

    The purpose of this study was to assess the repeatability of corneal topography measurements in dry eye patients and healthy controls. Participants underwent consecutive corneal topography measurements (Sirius; Costruzione Strumenti Oftalmici, Florence, Italy). Two images with acquisition quality higher than 90% were accepted. The following parameters were evaluated: minimum and central corneal thickness, aqueous depth, apex curvature, anterior chamber volume, horizontal anterior chamber diameter, iridocorneal angle, cornea volume, and average simulated keratometry. Repeatability was assessed by calculating intra-class correlation coefficient. Thirty-three patients with dry eye syndrome and 40 healthy controls were enrolled to the study. The groups were similar in terms of age (39 [18-65] vs. 30.5 [18-65] years, p=0.198) and gender (M/F: 4/29 vs. 8/32, p=0.366). Intra-class correlation coefficients among all topography parameters within both groups showed excellent repeatability (>0.90). The anterior segment measurements provided by the Sirius corneal topography system were highly repeatable for dry eye patients and are sufficiently reliable for clinical practice and research.

    To compare the effects of the surgical insult of cataract surgery on corneal inflammatory infiltration, neovascularization (NV) and lymphangiogenesis (LY) between the dry eye and non-dry eye in murine cataract surgery models. We established two groups of animals, one with normal eyes (non-dry eye) and the second with induced dry eyes. In both groups, we used surgical insults to mimic human cataract surgery, which consisted of lens extraction, corneal incision and suture. After harvesting of corneas on the 9(th) postoperative day and immunohistochemical staining, we compared NV, LY and CD11b+ cell infiltration in the corneas. Dry eye group had significantly more inflammatory infiltration (21.75%±7.17% vs 3.65%±1.49%; P=0.049). The dry eye group showed significantly more NV (48.21%±4.02% vs 26.24%±6.01%; P=0.016) and greater levels of LY (9.27%±0.48% vs 4.84%±1.15%; P=0.007). In corneas on which no surgery was performed, there was no induction of NV in both the dry and non-dry group, but dry eye group demonstrated more CD11b+ cells infiltration than the non-dry eye group (0.360%±0.160% vs 0.023%±0.006%; P=0.068). Dry eye group showed more NV than non-dry eye group in both topical PBS application and subconjunctival PBS injection (P=0.020 and 0.000, respectively). In a murine cataract surgery model, preexisting dry eye can induce more postoperative NV, LY, and inflammation in corneal tissue.

    Rebamipide with mucin secretagogue activity was recently approved for the treatment of dry eye. The efficacy and safety in the treatment of rebamipide were shown in two pivotal clinical trials. It was the aim of this study to evaluate the effect of 2% rebamipide ophthalmic suspension in patients with dry eye and analyze relevant factors for favorable effects of rebamipide in clinical practice. This was a retrospective cohort study of 48 eyes from 24 patients with dry eye treated with 2% rebamipide ophthalmic suspension. Dry eye-related symptom score, tear film break-up time (TBUT), fluorescein ocular surface staining score (FOS) and the Schirmer test were used to collect the data from patients at baseline, and at 2, 4, 8, and 12 week visits. To determine the relevant factors, multiple regression analyses were then performed. Mean dry eye-related symptom score showed a significant improvement from the baseline (14.5 points) at 2, 4, 8 and 12 weeks (9.80, 7.04, 7.04 and 7.83 points, corrected P value treatment. For ocular symptoms, three parameters (foreign body sensation, dry eye sensation and ocular discomfort) showed significant improvements at all visits. The multiple regression analyses showed that the fluorescein conjunctiva staining score was significantly correlated with the changes of dry eye-related symptom score at 12 weeks (P value = 0.017) and dry eye-related symptom score was significantly correlated with independent variables for the changes of FOS at 12 weeks (P value = 0.0097). Two percent rebamipide ophthalmic suspension was an effective therapy for dry eye patients. Moreover the fluorescein conjunctiva staining score and dry eye-related symptom score might be good relevant factors for favorable effects of rebamipide.

    Purpose We determine if visual field loss from glaucoma and/or measures of dry eye severity are associated with difficulty searching, as judged by slower search times on a text-based search task. Methods Glaucoma patients with bilateral visual field (VF) loss, patients with clinically significant dry eye, and normally-sighted controls were enrolled from the Wilmer Eye Institute clinics. Subjects searched three Yellow Pages excerpts for a specific phone number, and search time was recorded. Results A total of 50 glaucoma subjects, 40 dry eye subjects, and 45 controls completed study procedures. On average, glaucoma patients exhibited 57% longer search times compared to controls (95% confidence interval [CI], 26%–96%, P Dry eye subjects demonstrated similar search times compared to controls, though worse Ocular Surface Disease Index (OSDI) vision-related subscores were associated with longer search times (P dry eye (P > 0.08 for Schirmer's testing without anesthesia, corneal fluorescein staining, and tear film breakup time). Conclusions Text-based visual search is slower for glaucoma patients with greater levels of VF loss and dry eye patients with greater self-reported visual difficulty, and these difficulties may contribute to decreased quality of life in these groups. Translational Relevance Visual search is impaired in glaucoma and dry eye groups compared to controls, highlighting the need for compensatory strategies and tools to assist individuals in overcoming their deficiencies.

    Dry eye disease (DED) is a prevalent inflammatory disorder of the lacrimal functional unit of multifactorial origin leading to chronic ocular surface disease, impaired quality of vision, and a wide range of complications, eventually causing a reduction in quality of life. It still is a frustrating disease because of the present scarcity of therapies that can reverse, or at least stop, its progression. A comprehensive literature survey of English-written scientific publications on the role of inflammation in DED. New investigations have demonstrated that a chronic inflammatory response plays a key role in the pathogenesis of human DED. Additionally, correlations between inflammatory molecules and clinical data suggest that inflammation can be responsible for some of the clinical symptoms and signs. Research efforts to clarify its pathophysiology are leading to a better understanding of DED, demonstrating that inflammation, in addition to many other factors, plays a relevant role.

    Autophagy is known to be implicated in the pathogenesis of Sjögren syndrome (SS), but evidences are limited. We aimed to examine the levels of autophagy markers in tear film and conjunctival epithelial cells from SS dry eye patients, and analyze their correlations with clinical features. Patients with SS dry eye exhibited lower Schirmer values, lower tear breakup time, and higher ocular staining scores. In tears, ATG5 and LC3B-II/I levels were significantly higher in SS dry eye. ATG5 and LC3B-II mRNA in the conjunctiva were also elevated in SS dry eye compared with non-SS dry eye. The immunostaining of conjunctival epithelium showed a punctate pattern of ATG5 and LC3B-II in SS dry eye. These staining patterns were also observed in the lacrimal gland of SS animal models. ATG5 levels in tears and the conjunctival epithelium strongly correlated with ocular staining scores, and one month of topical corticosteroid treatment reduced both ATG5 and LC3B-II/I levels in tear film and the conjunctival epithelium of patients with SS dry eye. Our results suggest that autophagy is enhanced or dysregulated in SS and autophagy markers may be serve as both diagnostic and therapeutic biomarkers in SS dry eye.

    To assess the impact of autologous serum eye drops on the level of ocular surface apoptosis in patients with bilateral severe dry eye disease. This prospective study was conducted on 10 patients with severe dry eye due to graft versus host disease (group 1) and 6 patients with severe dry eye due to primary Sjögren's syndrome (group 2). Impression cytology specimens from the bulbar conjunctiva were obtained before and after a three-month treatment with 20% autologous serum eye drops applied a maximum of 12 times a day together with regular therapy with artificial tears. The percentage of apoptotic epithelial cells was evaluated immunochemically using anti-active caspase 3 antibody. In group 1, the mean percentage of apoptotic cells was 3.6% before the treatment. The three-month treatment led to a significant decrease to a mean percentage of 1.8% (P = 0.028). The mean percentage of apoptotic conjunctival cells decreased from 5.4% before the treatment to 3.8% in group 2; however, these results did not reach the level of significance. Three-month autologous serum treatment led to the improvement of ocular surface apoptosis, especially in the group of patients with severe dry eye due to graft versus host disease. This result supports the very positive effect of autologous serum on the ocular surface in patients suffering from severe dry eye.

    Dry eye disease (DED) is a common condition causing substantial burden. A randomized, controlled, single-masked study was performed in 40 patients with mild to moderate DED to evaluate the efficacy and safety of a collyrium based on crosslinked hyaluronic acid (XLHA) with coenzyme Q10 (CoQ10). Enrolled subjects were divided into 2 groups: group A, treated with XLHA + CoQ10; and group B, treated with hyaluronic acid (HA). Eyedrops were administered 4 times daily for 3 months. The Ocular Surface Disease Index (OSDI) questionnaire, tear break-up time (TBUT), corneal and conjunctival staining, and meibomian gland assessment (MGD) were evaluated; furthermore, corneal aesthesiometry, in vivo corneal confocal microscopy, visual acuity, intraocular pressure (IOP), and fundus examination were performed. At the end of treatment, OSDI score significantly decreased in groups A and B (p<0.01 and p<0.05, respectively); the decrease was significantly higher in group A. Corneal staining decreased in both groups, with lower scores in group A. The MGD was significantly ameliorated in group A patients. No differences were found for corneal aesthesiometry or TBUT. Epithelial cell reflectivity was significantly reduced only in group A. For keratocytes and stromal matrix parameters, there was a significant improvement in group A. No changes were found for visual acuity, IOP, or fundus examination. The XLHA + CoQ10 treatment showed greater effectiveness in DED compared to HA alone, probably due to the longer permanency on ocular surface and the antioxidant activity of CoQ10. Therefore, XLHA + CoQ10 eyedrops could represent a new possibility in dry eye treatment.

    The purpose was to study dry eye following phacoemulsification surgery and analyze its relation to associated intra-operative risk factors. A prospective observational study was carried out on 100 eyes of 100 patients without preoperative dry eye. Schirmer's Test I, tear meniscus height, tear break-up time, and lissamine green staining of cornea and conjunctiva were performed preoperatively and at 5 days, 10 days, 1-month, and 2 months after phacoemulsification surgery, along with the assessment of subjective symptoms, using the dry eye questionnaire. The correlations between these values and the operating microscope light exposure time along with the cumulative dissipated energy (CDE) were investigated. There was a significant deterioration of all dry eye test values following phacoemulsification surgery along with an increase in subjective symptoms. These values started improving after 1-month postoperatively, but preoperative levels were not achieved till 2 months after surgery. Correlations of dry eye test values were noted with the operating microscope light exposure time and CDE, but they were not significant. Phacoemulsification surgery is capable of inducing dry eye, and patients should be informed accordingly prior to surgery. The clinician should also be cognizant that increased CDE can induce dry eyes even in eyes that were healthy preoperatively. In addition, intraoperative exposure to the microscopic light should be minimized.

    To evaluate the tear osmolarity in patients with dry eye syndrome related to primary Sjögren's Syndrome (SS). Twenty eyes of 10 patients with dry eye and primary SS (Group 1) and 20 eyes of 20 subjects who do not have dry eye syndrome (Group 2) were included in this cross-sectional study. In all eyes, ophthalmic examination was performed in the same order: International Ocular Surface Disease Index survey, visual acuity assessment, conjunctival hyperemia scoring, tear osmolarity measurement with TearLab(™) Osmolarity System, tear film break-up time assessment, corneal fluorescein staining scoring, ocular surface Lissamine Green staining scoring, anesthetized Schirmer test. Dry eye severity was graded according to Dry Eye Workshop (DEWS) classification system. Four eyes with grade 1, four eyes with grade 2, seven eyes with grade 3, and five eyes with grade 4 dryness, according to DEWS system, were included. The mean tear osmolarity value was 301.9 ± 11.40 mOsm/L (range: 290-328) in Group 1, and 294.85 ± 8.33 mOsm/L (range: 283-311) in Group 2 (p = 0.03). In Group 1, tear osmolarity values were positively correlated with OSDI scores (r(18) = 0.55, r(2) = 0.31, p = 0.01), DEWS classification grades (r(18) = 0.73, r(2) = 0.54, p dry eye syndrome related to primary SS compared to control subjects, and positively correlated with the severity of dry eye.

    Publication of the DEWS report in 2007 established the state of the science of dry eye disease (DED). Since that time, new evidence suggests that a rethinking of traditional concepts of dry eye disease is in order. Specifically, new evidence on the epidemiology of the disease, as well as strategies for diagnosis, have changed the understanding of DED, which is a heterogeneous disease associated with considerable variability in presentation. These advances, along with implications for clinical care, are summarized herein. The most widely used signs of DED are poorly correlated with each other and with symptoms. While symptoms are thought to be characteristic of DED, recent studies have shown that less than 60% of subjects with other objective evidence of DED are symptomatic. Thus the use of symptoms alone in diagnosis will likely result in missing a significant percentage of DED patients, particularly with early/mild disease. This could have considerable impact in patients undergoing cataract or refractive surgery as patients with DED have less than optimal visual results. The most widely used objective signs for diagnosing DED all show greater variability between eyes and in the same eye over time compared with normal subjects. This variability is thought to be a manifestation of tear film instability which results in rapid breakup of the tearfilm between blinks and is an identifier of patients with DED. This feature emphasizes the bilateral nature of the disease in most subjects not suffering from unilateral lid or other unilateral destabilizing surface disorders. Instability of the composition of the tears also occurs in dry eye disease and shows the same variance between eyes. Finally, elevated tear osmolarity has been reported to be a global marker (present in both subtypes of the disease- aqueous-deficient dry eye and evaporative dry eye). Clinically, osmolarity has been shown to be the best single metric for diagnosis of DED and is directly related to

    To evaluate the relationship between androgen levels and subjective and objective measures of dry eye syndrome (DES). A total of 263 male patients from the Miami Veterans Affairs Medical Center eye clinic aged ≥50 were recruited for this prospective cross-sectional study. Patients completed Dry Eye Questionnaire 5, underwent tear film evaluation, and had serum androgen levels measured. The correlations between androgen levels, DES composite scores, DES symptoms, and global, lipid, and aqueous tear film parameters were evaluated. Two hundred sixty-three patients with a mean age of 69 (50-95) were examined. There was no linear association between composite DES scores (generated using latent class analysis) and androgen levels. However, eyes with high DES scores (0.95-1.0) had higher levels of sex hormone-binding globulin (P = 0.03) and lower levels of dehydroepiandrosterone sulfate (DHEAS) (P = 0.02), androstenedione (A) (P = 0.02), and androstane-3α,17β-diol glucuronide (P = 0.03) compared to eyes with intermediate (0.05-0.95) or low (0-0.05) scores. There were no strong correlations between tear film measures and androgen levels. Regarding global parameters, a weak inverse correlation was found between corneal staining and A (r = -0.17, P = 0.009). For lipid parameters, a weak correlation existed between tear breakup time (TBUT) and A (r = 0.15, P = 0.02). When considering aqueous and lipid deficiency independently, the association between TBUT and A existed only with aqueous tear deficiency (r = 0.66, P = 0.002). Regarding aqueous parameters, a weak correlation existed between Schirmer test and DHEAS (r = 0.13, P = 0.047) and A (r = 0.21, P = 0.001). There was a weak correlation between higher levels of androstenedione and healthier global, lipid, and aqueous tear film parameters.

    To evaluate the treatment of autologous serum eye drops (ASED) on dry eyes in patients with graft-versus-host disease (GVHD). A retrospective chart review of 35 patients with a history of ocular GVHD following hematopoietic stem cell transplantation that used ASED to alleviate dry eye symptoms was performed. Patients were categorized into three different groups. If patients had available ophthalmic data before and after starting treatment was group 1 (n = 14), had available ophthalmic data after starting treatment in group 2 (n = 10) and had available ophthalmic data before treatment or did not have any data after starting treatment in group 3 (n = 11). Data were collected on patient's age, gender, primary diagnosis, visual acuity and fluorescein corneal staining were collected on individual eyes in order to evaluate the efficacy of the ASED on alleviating dry eye-related signs and symptoms. No adverse ocular effect from the ASED was found in our series (except one fungal keratitis). All patients reported either improvement (55%) or stability (45%) in their ocular symptoms upon the use of ASED. In patients with available data before and after starting treatment, the corneal staining score improved by a median of 1 (p = 0.003) and the LogMAR visual acuity had a non-significant improvement. In our study, ASED used by patients with ocular GVHD were both safe and effective. ASED should be considered in patients with GVHD who suffer from dry eyes.

Patients and methods: Fifty patients with diabetes were enrolled. Demographic information and past medical history were recorded. Symptoms were assessed using the ocular surface disease index (OSDI. Tear osmolarity of each eye was measured with the TearLab® Osmolarity System. Results: The majority of the subjects were female (76%, African American (56%, and/or had a diagnosis of type 2 diabetes (82%. The mean ± standard deviation (SD for age was 54.6±13.4, and maximum tear osmolarity was 304.6±12.7 mOsm/L. Men had higher osmolarity than women (mean ± standard error (SE 311.8±4.0 mOsm/L versus 302.3±1.9 mOsm/L, P=0.02. Age, race, use of artificial tears, years of diabetes, and hemoglobin A1c did not have a statistically significant association with tear osmolarity. Longer duration of diabetes was associated with lower (less severe OSDI scores (r=-0.35, P=0.01. Higher tear osmolarity was associated with lower (less severe OSDI scores (r=-0.29, P=0.04. Conclusion: Approximately half of the diabetic subjects in our study had elevated tear osmolarity, and half of our population also reported symptoms consistent with dry eye disease. However, the two were slightly inversely related in that those with higher osmolarity reported fewer symptoms. Subjects with a longer duration of diabetes also reported fewer dry eye symptoms. Therefore, health care providers should be aware that patients who are most likely to have ocular surface disease, including those with

    To evaluate the effect of punctal plug use in preventing dry eye after laser in situ keratomileusis (LASIK). A randomized clinical trial at a tertiary eye care center, Riyadh, Saudi Arabia. Participants underwent LASIK for myopia in both eyes and a lower punctal occlusion in one eye only while the other eye served as control. Both eyes received the same postoperative medications except for lubricant duration (subject eye: four times per day for one week; control eye: four times per day for 6 months). Participants were evaluated at 1 week, 2, and 6 months after surgery for signs and symptoms of dry eye. The main outcome measures were visual acuity; ocular surface parameters; and Ocular Surface Disease Index questionnaire. Seventy-eight eyes of 39 patients were included in this study. The Ocular Surface Disease Index scores of eyes with punctal plugs were better at all follow-up visits, and the differences between both eyes were statistically significant (1 week, p eyes was higher in eyes with punctal plugs for all ocular surface parameters (Schirmer 1 test, 94.9%; tear breakup time, 77.8%; punctate epithelial keratitis score, 71.8%) compared to eyes without occlusion (Schirmer 1 test, 92.3%; tear breakup time, 58.3%; punctate epithelial keratitis score, 53.8%); however, such differences were not statistically significant. Punctal plug insertion after LASIK surgeries may minimize the need for frequent lubricant application and hence improve patient satisfaction.

    The presence of clinically significant inflammation has been confirmed in the tears of 40%-65% of patients with symptoms of dry eye. Ocular surface inflammation may lead to tear film instability, epithelial cell irregularities, and permeability, resulting in chronic symptomatic pain and fluctuating vision as well as negative surgical outcomes. A retrospective single center medical chart review of 100 patients was conducted. All patients were tested with the InflammaDry test to determine if patients exhibited elevated levels of matrix metalloproteinase 9 (MMP-9). InflammaDry-positive patients were started on a combination of cyclosporine 0.05% twice daily, 2,000-4,000 mg oral omega-3 fatty acids, and frequent artificial tear replacement. InflammaDry-negative patients were started on 2,000-4,000 mg of oral omega-3 fatty acids and frequent artificial tear replacement. Each patient was retested at ~90 days. A symptom questionnaire was performed at the initial visit and at 90 days. 60% of the patients with dry eye symptoms tested positive for elevated MMP-9 at the initial visit. 78% of all patients returned for follow-up at ~90 days including 80% (48/60) of the previously InflammaDry-positive patients and 75% (30/40) of the previously InflammaDry-negative patients. A follow-up symptom questionnaire reported at least 75% symptomatic improvement in 65% (31/48) of the originally InflammaDry-positive patients and in 70% (21/30) of the initially InflammaDry-negative patients. Symptomatic improvement of at least 50% was reported in 85% (41/48) of previously InflammaDry-positive patients and 86% (26/30) of previously InflammaDry-negative patients. Following treatment, 54% (26/48) of previously InflammaDry-positive patients converted to a negative InflammaDry result. Identifying which symptomatic dry eye patients have underlying inflammation may predict patient responses to treatment and influence clinical management strategies.

    To develop the Chinese version of quality of life scale for dry eye patients based on the Impact of Dry Eye on Everyday Life (IDEEL) questionnaire and to assess the reliability and validity of the developed scale. The original IDEEL was adapted cross-culturally to Chinese language and further developed following standard procedures. A total of 100 Chinese patients diagnosed with dry eye syndrome were included to investigate the psychometric properties of the Chinese version of scale. Psychometric tests included internal consistency (Cronbach's ɑ coefficients), construct validity (exploratory factor analysis), and known-groups validity (the analysis of variance). The Chinese version of Dry Eye Related Quality of Life (CDERQOL) Scale contains 45 items classified into 5 domains. Good to excellent internal consistency reliability was demonstrated for all 5 domains (Cronbach's ɑ coefficients range from 0.716 to 0.913). Construct validity assessment indicated a consistent factorial structure of the CDERQOL scale with hypothesized construct, with the exception of "Dry Eye Symptom-Bother" domain. All domain scores were detected with significant difference across three severity groups of dry eye patients (P dry eye syndrome among Chinese population, and could be used as a supplementary diagnostic and treatment-effectiveness measure.

    The efficacy of hormone therapy (HT) on dry eye syndrome remains debatable. To study the efficacy of HT on dry eye syndrome. A randomized controlled, double blind, parallel group, community-based study in 42 post-menopausal patients was conducted. The patients had dry eye syndrome and were not taking any medications. They were assigned to one of two groups. Group A comprised 21 patients given transdermal 17 beta-estradiol (50 mg/day) and medroxy progesterone acetate (2.5 mg/day) continuously for three months and group B comprised 21 patients given both transdermal and oral placebo. Participants in the study were included for final analysis. The improvement of dry eye symptoms were measured by visual analog scale, tear secretion, intraocular pressure, corneal thickness, and tear breakup time determined before treatment and at 6 and 12 weeks of treatment. At 12 weeks, the number of patients who reported improvement of dry eye symptoms was greater in the HT group than that in the placebo group. However, the difference was not statistically significant (RR 0.25, 95% CI 0.04-2.80 and 0.60, 95% CI 0.33-2.03 in right and left eye, respectively). For other parameters, there was no significant difference between the two groups. According to the present study, there is no strong evidence to support the use of HT for treating dry eye syndrome. The limited number of participants included in the present study may have contributed to the insignificant effects.

    To evaluate the ability of Systane(®) Balance (SYSB) administered four times per day for 4 weeks to increase noninvasive tear film break-up time (NITFBUT) over baseline compared with a saline (SAL) control in patients with lipid-deficient dry eye (DE). Patients aged ≥18 years with DE and evidence of meibomian gland dysfunction (ie, abnormal gland expression and missing meibomian glands) were included in this randomized, parallel-group, controlled, investigator-masked comparison study. Patients were randomized to SYSB or SAL four times daily for 4 weeks. The primary efficacy variable was mean change in NITFBUT from baseline at week 4. Ocular surface staining, goblet cell density, and meibomian gland expression were also assessed. Safety assessments included adverse events (AEs), best-corrected visual acuity, and ocular signs. A total of 49 patients received study treatments (SYSB, n=25; SAL, n=24). Most patients were women (67.4%) and Caucasian (63.3%); mean ± standard deviation (SD) age was 44±19 years. DE characteristics at baseline were similar between groups. After 4 weeks of treatment, the mean ± SD NITFBUT increase from baseline was significantly greater with SYSB (2.83±0.74 seconds) compared with SAL (0.66±0.55 seconds; P<0.001, t-test). Improvements in conjunctival and corneal staining, percentage of patients with increased goblet cell density, and meibomian gland expression were also observed with 4 weeks of SYSB over SAL. No AEs were reported for either treatment group; best-corrected visual acuity and ocular signs remained stable or improved compared with baseline. SYSB restored tear film stability, improved ocular surface healing, and improved meibomian gland functionality after 4 weeks of use in patients with lipid-deficient DE. No AEs were reported with either SYSB or SAL.

    Purpose. This study aims to evaluate dry eye and ocular surface conditions of myopic teenagers by using questionnaire and clinical examinations. Methods. A total of 496 eyes from 248 myopic teenagers (7–18 years old) were studied. We administered Ocular Surface Disease Index (OSDI) questionnaire, slit-lamp examination, and Keratograph 5M. The patients were divided into 2 groups based on OSDI dry eye standard, and their ocular surfaces and meibomian gland conditions were evaluated. Results. The tear meniscus heights of the dry eye and normal groups were in normal range. Corneal fluorescein scores were significantly higher whereas noninvasive break-up time was dramatically shorter in the dry eye group than in the normal group. All three meibomian gland dysfunction parameters (i.e., meibomian gland orifice scores, meibomian gland secretion scores, and meibomian gland dropout scores) of the dry eye group were significantly higher than those of the normal group (P dry eye in myopic teenagers is 18.95%. Meibomian gland dysfunction plays an important role in dry eye in myopic teenagers. The Keratograph 5M appears to provide an effective noninvasive method for assessing ocular surface situation of myopic teenagers. PMID:26881059

    Dry eye disease (DED), defined as a multifactorial disease of tears and ocular surface, results in symptoms of discomfort, ocular irritation, visual disturbance and tear film instability. This syndrome is accompanied of ocular surface inflammation and it is produced by a deficient activity of the lacrimal functional unit. In addition, it is associated with systemic autoimmune diseases such as Sjögren´s Syndrome, rheumatoid arthritis, systemic lupus erythematosus and some drug administration. The treatment of dry eye disease is based on the typical signs and symptoms of dry eye, which are associated with hyperosmolarity, ocular surface inflammation, discomfort, visual disturbance, and tear film instability. Areas covered: This review is focused on synthetic drugs currently used in clinical practice, from phase III development onwards to treat the ocular surface signs and symptoms of dry eye disease. Expert opinion: The multifactorial disease and the lack of correlation between signs and symptoms imply that not all the pharmacological approaches will be successful for dry eye. The correct design of the clinical trials, with appropriate endpoints, and the type of dry eye under study are complicated but mandatory. The anti-inflammatory and secretagogues drugs are both the main compounds to currently treat the dry eye disease.

  2. Altered Mucin and Glycoprotein Expression in Dry Eye Disease.

    Stephens, Denise N; McNamara, Nancy A

    2015-09-01

    Mucins are among the many important constituents of a healthy tear film. Mucins secreted and/or associated with conjunctival goblet cells, ocular mucosal epithelial cells, and the lacrimal gland must work together to create a stable tear film. Although many studies have explored the mechanism(s) whereby mucins maintain and protect the ocular surface, the effects of dry eye on the structure and function of ocular mucins are unclear. Here, we summarize current findings regarding ocular mucins and how they are altered in dry eye. We performed a literature review of studies exploring the expression of mucins produced and/or associated with tissues that comprise the lacrimal functional unit and how they are altered in dry eye. We also summarize new insights on the immune-mediated effects of aqueous tear deficiency on ocular surface mucins that we discovered using a mouse model of dry eye. Although consistent decreases in MUC5AC and altered expression of membrane-bound mucins have been noted in both Sjögren and non-Sjögren dry eye, many reports of altered mucins in dry eye are contradictory. Mechanistic studies, including our own, suggest that changes in the glycosylation of mucins rather than the proteins themselves may occur as the direct result of local inflammation induced by proinflammatory mediators, such as interleukin-1. Altered expression of ocular mucins in dry eye varies considerably from study to study, likely attributed to inherent difficulties in analyzing small-volume tear samples, as well as differences in tear collection methods and disease severity in dry eye cohorts. To better define the functional role of ocular mucin glycosylation in the pathogenesis of dry eye disease, we propose genomic and proteomic studies along with biological pathway analysis to reveal novel avenues for exploration.

    To investigate the effect of the viscous agents, hydroxypropyl methylcellulose (HPMC), carbomer, povidone, and a combination of HPMC and povidone on corneal density in patients with dry eye disease. In total, 98 eyes of 49 patients suffering from dry eye and 65 eyes of 33 healthy age-matched individuals were included in this prospective, randomized study. Corneal morphology was documented with Scheimpflug photography and corneal density was analyzed in 5 anatomical layers (epithelium, bowman membrane, stroma, descemet's membrane, and endothelium). Corneal density was evaluated for the active ingredients HPMC, carbomer, povidone, and a combination of HPMC and povidone as the viscous agents contained in the artificial tear formulations used by the dry eye patients. Data were compared to the age-matched healthy control group without medication. Corneal density in dry eye patients was reduced in all 5 anatomical layers compared to controls. Corneal density was highest and very close to control in patients treated with HPMC containing ocular lubricants. Patients treated with lubricants, including carbomer as the viscous agent displayed a significant reduction of corneal density in layers 1 and 2 compared to control. HPMC containing ocular lubricants can help to maintain physiological corneal density and may be beneficial in the treatment of dry eye disease.

In a previous study, perfluorohexyloctane, a semifluorinated alkane, has been demonstrated to significantly increase tear film breakup time and to reduce corneal fluorescein staining in patients with evaporative DED, thereby vastly reducing dry eye-related symptoms. This study was set up to evaluate perfluorohexyloctane in a larger population of patients with Meibomian gland dysfunction. Seventy-two patients with Meibomian gland disease and associated dry eye received 1 drop of perfluorohexyloctane 4 times daily during an observational, prospective, multicenter, 6-8-week study. Clinical assessment included best-corrected visual acuity, intraocular pressure, Schirmer test I, tear film breakup time, anterior and posterior blepharitis assessment, number of expressible Meibomian glands, meibum quality and quantity, ocular surface fluorescein staining, lid margin and symptom assessment, and Ocular Surface Disease Index (OSDI © ). From the 72 patients recruited, 61 completed the trial per protocol. Nine patients did not apply the medication as recommended and 2 patients were lost to follow-up. Tear film breakup time, corneal and conjunctival fluorescein staining, number of expressible Meibomian glands, and severity of anterior and posterior blepharitis significantly improved after 6-8 weeks of perfluorohexyloctane application. In addition, symptoms improved as demonstrated by a significant decrease of OSDI-values from 37 (±13) to 26 (±16). In concordance with previous findings, 6-8 weeks of topical application of perfluorohexyloctane significantly improves clinical signs of Meibomian gland disease and associated mild to moderate DED.

    Dry eye disease is a major public health problem that affects millions of people worldwide. It is presently treated with artificial tear and anti-inflammatory eye drops that are generally administered several times a day and may have limited therapeutic efficacy. To improve convenience and efficacy, a dexamethasone (Dex) loaded nanowafer (Dex-NW) has been developed that can release the drug on the ocular surface for a longer duration of time than drops, during which it slowly dissolves. The Dex-NW was fabricated using carboxymethyl cellulose polymer and contains arrays of 500 nm square drug reservoirs filled with Dex. The in vivo efficacy of the Dex-NW was evaluated using an experimental mouse dry eye model. These studies demonstrated that once a day Dex-NW treatment on alternate days during a five-day treatment period was able to restore a healthy ocular surface and corneal barrier function with comparable efficacy to twice a day topically applied dexamethasone eye drop treatment. The Dex-NW was also very effective in down regulating expression of inflammatory cytokines (TNF-α, and IFN-γ), chemokines (CXCL-10 and CCL-5), and MMP-3, that are stimulated by dry eye. Despite less frequent dosing, the Dex-NW has comparable therapeutic efficacy to topically applied Dex eye drops in experimental mouse dry eye model, and these results provide a strong rationale for translation to human clinical trials for dry eye.

    For the last 20 years, a great amount of evidence has accumulated through epidemiological studies that most of the dry eye disease encountered in daily life, especially in video display terminal (VDT) workers, involves short tear film breakup time (TFBUT) type dry eye, a category characterized by severe symptoms but minimal clinical signs other than short TFBUT. An unstable tear film also affects the visual function, possibly due to the increase of higher order aberrations. Based on the change in the understanding of the types, symptoms, and signs of dry eye disease, the Asia Dry Eye Society agreed to the following definition of dry eye: "Dry eye is a multifactorial disease characterized by unstable tear film causing a variety of symptoms and/or visual impairment, potentially accompanied by ocular surface damage." The definition stresses instability of the tear film as well as the importance of visual impairment, highlighting an essential role for TFBUT assessment. This paper discusses the concept of Tear Film Oriented Therapy (TFOT), which evolved from the definition of dry eye, emphasizing the importance of a stable tear film. Copyright © 2016 The Author(s).

    To evaluate efficacy and safety of transcutaneous application of electrical current on symptoms and clinical signs of dry eye (DE). 27 patients with DE underwent transcutaneous electrostimulation with electrodes placed onto the periorbital region of both eyes and manual stimulation with a hand-piece conductor moved by the operator. Each patient underwent 12 sessions of 22 min spread over 2 months, two sessions per week in the first month and one session per week in the second month. Ocular Surface Disease Index (OSDI) questionnaire, tear break-up time (TBUT), fluorescein staining of the cornea, Schirmer I test and adverse events were evaluated at baseline, at end of treatment and at 6 and 12 months. OSDI improved from 43.0±19.2 at baseline to 25.3±22.1 at end of treatment (mean±SD, p=0.001). These effects were substantially maintained at 6-month and 12-month follow-up evaluations. Improvement of the values of TBUT was recorded for the right eye at the end of treatment (p=0.003) and found in the left eye after 12 months (p=0.02). The Oxford scores changed in both eyes at the end of treatment and at the 6-month evaluation (peye at the 12-month evaluation (p=0.035). Schirmer I improved significantly at the end of treatment in the left eye (p=0.001) and in both eyes at the 12-month evaluation (p=0.004 and p=0.039 for the left and right eye, respectively). A significant reduction of the use of tear substitutes was found at the end of treatment (p=0.003), and was maintained during the follow-up (ptreatment satisfying. Transcutaneous electrical stimulation was shown to improve DE, both subjectively and objectively, without any adverse effects and has the potential to enlarge the armamentarium for treating DE.

    To compare the concentrations of epitheliotrophic factors in autologous serum eye drops (ASE) prepared from sera of chronic Stevens-Johnson syndrome (SJS) patients with dry eyes to those prepared from non-autoimmune dry eye controls and to study the stability of the epitheliotrophic factors in different storage conditions. Twenty-percent ASE were prepared from 10 chronic SJS patients with dry eyes and 10 age-matched non-autoimmune dry eye controls. The concentrations of major epitheliotrophic factors comprising epidermal growth factor (EGF), transforming growth factor-beta1 (TGF-β1), transforming growth factor-beta2 (TGF-β2), and fibronectin in those ASE preparations were determined by enzyme-linked immunosorbent assay (ELISA) at baseline and after different storage conditions: at 4 °C for 1 week and 1 month; and at -20 °C for 1, 3 and 6 months. There were no significant differences in the concentrations of EGF, TGF-β1, TGF-β2 and fibronectin in 20% ASE between the SJS and control groups (EGF: 176.9 ± 40.9 vs. 185.5 ± 36.9 pg/mL, TGF-β1: 9.5 ± 2.1 vs. 9.5 ± 1.9 ng/mL, TGF-β2: 55.3 ± 30.0 vs. 63.91 ± 45.6 pg/mL and fibronectin: 70.5 ± 20.2 vs. 62.2 ± 21.3 µg/mL, respectively). These factors were stable at 4 °C for up to 1 month. Storage at -20 °C for up to 6 months resulted in a slight decrease in TGF-β1 (SJS: from 9.5-8.4 ng/mL, p dry eye patients, and that ASE should be sufficiently stable for up to 6 months, if stored properly at -20 °C.

  11. Review: The Lacrimal Gland and Its Role in Dry Eye

    Directory of Open Access Journals (Sweden)

    Full Text Available The human tear film is a 3-layered coating of the surface of the eye and a loss, or reduction, in any layer of this film may result in a syndrome of blurry vision and burning pain of the eyes known as dry eye. The lacrimal gland and accessory glands provide multiple components to the tear film, most notably the aqueous. Dysfunction of these glands results in the loss of aqueous and other products required in ocular surface maintenance and health resulting in dry eye and the potential for significant surface pathology. In this paper, we have reviewed products of the lacrimal gland, diseases known to affect the gland, and historical and emerging dry eye therapies targeting lacrimal gland dysfunction.

Materials and Methods: Thirty-four children with CRF and 89 age- and sex-matched healthy subjects were included in this prospective study. Tear break-up time (TBUT and Schirmer test, subjective symptoms (burning, foreign-body sensation, hyperemia, itching, tearing, calcification of the conjunctiva, and corneal staining were evaluated. In the study group, relation between TBUT and Schirmer test results and duration of disease, duration of dialysis, serum calcium, phosphorus, urea, creatinine, and total protein levels were recorded. For statistical analysis, t-test, chi-square test, and Pearson’s correlation test were used. Results: In the study group, burning sensation was statistically higher than in the control group. Except this, according to the other subjective tests and corneal staining, there were no significant differences between the two groups (p>0.05. Conjunctival calcification was seen in 3 patients in the study group. The mean Schirmer test result was 21.1±8.0 and 23.7±8.0 mm in the study and control groups, respectively (p=0.101. The mean TBUT was 12.5±5.2 seconds (s in the study and 16.0±5.5 s in the control groups (p=0.002. None of the disease-related variables (the mean duration of disease and dialysis, serum calcium, phosphorus, urea, creatinine, and total protein levels were associated with dry eye syndrome (p>0.05. Conclusion: TBUT was statistically significantly lower, but Schirmet test result was not significantly different between children with CRF and age- and sex-matched healthy subjects. The disease-related variables have no effect in the development of dry eyes. (Turk J Ophthalmol 2014; 44: 196-200

    Dry eye is one of the most commonly encountered problems in ophthalmology. Signs can include punctate epithelial erosions, hyperemia, low tear lakes, rapid tear break-up time, and meibomian gland disease. Current methods of diagnosis include a slit-lamp examination with and without different stains, including fluorescein, rose bengal, and lissamine green. Other methods are the Schirmer test, tear function index, tear break-up time, and functional visual acuity. Emerging technologies include meniscometry, optical coherence tomography, tear film stability analysis, interferometry, tear osmolarity, the tear film normalization test, ocular surface thermography, and tear biomarkers. Patient-specific considerations involve relevant history of autoimmune disease, refractive surgery or use of oral medications, and allergies or rosacea. Other patient considerations include clinical examination for lid margin disease and presence of lagophthalmos or blink abnormalities. Given a complex presentation and a variety of signs and symptoms, it would be beneficial if there was an inexpensive, readily available, and reproducible diagnostic test for dry eye. PMID:24672224

    Dry eye has gained recognition as a public health problem given its prevalence, morbidity, and cost implications. Dry eye can have a variety of symptoms including blurred vision, irritation, and ocular pain. Within dry eye-associated ocular pain, some patients report transient pain whereas others complain of chronic pain. In this review, we will summarize the evidence that chronicity is more likely to occur in patients with dysfunction in their ocular sensory apparatus (ie, neuropathic ocular pain). Clinical evidence of dysfunction includes the presence of spontaneous dysesthesias, allodynia, hyperalgesia, and corneal nerve morphologic and functional abnormalities. Both peripheral and central sensitizations likely play a role in generating the noted clinical characteristics. We will further discuss how evaluating for neuropathic ocular pain may affect the treatment of dry eye-associated chronic pain. PMID:25376119

    In this study, we explore the usage of ocular surface temperature (OST) decay patterns to distinguished between dry eye patients with aqueous deficient dry eye (ADDE) and meibomian gland dysfunction (MGD). The OST profiles of 20 dry eye subjects were measured by a long-wave infrared thermal camera in a standardized environment (24 °C, and relative humidity (RH) 40%). The subjects were instructed to blink every 5 s after 20 ∼ 25 min acclimation. Exponential decay curves were fit to the average temperature within a region of the central cornea. We find the MGD subjects have both a higher initial temperature (p model, referred to as the thermal impulse perturbation (TIP) model. We conclude that long-wave-infrared thermal imaging is a plausible tool in assisting with the classification of dry eye patient. Copyright © 2015 Elsevier Ltd. All rights reserved.

    To determine the prevalence of dry eye syndrome in the general 40- to 64-year-old population of Shahroud, Iran. Population-based cross-sectional study. Through cluster sampling, 6311 people were selected and 5190 participated. Assessment of dry eye was done in a random subsample of 1008 people. Subjective assessment for dry eye syndrome was performed using Ocular Surface Disease Index questionnaire. In addition, the following objective tests of dry eye syndrome were employed: Schirmer test, tear break-up time, and fluorescein and Rose Bengal staining using the Oxford grading scheme. Those with an Ocular Surface Disease Index score ≥23 were considered symptomatic, and dry eye syndrome was defined as having symptoms and at least one positive objective sign. The prevalence of dry eye syndrome was 8.7% (95% confidence interval 6.9-10.6). Assessment of signs showed an abnormal Schirmer score in 17.8% (95% confidence interval 15.5-20.0), tear break-up time in 34.2% (95% confidence interval 29.5-38.8), corneal fluorescein staining (≥1) in 11.3% (95% confidence interval 8.5-14.1) and Rose Bengal staining (≥3 for cornea and/or conjunctiva) in 4.9% (95% confidence interval 3.4-6.5). According to the Ocular Surface Disease Index scores, 18.3% (95% confidence interval 15.9-20.6) had dry eye syndrome symptoms. The prevalence of dry eye syndrome was significantly higher in women (P = 0.010) and not significantly associated with age (P = 0.291). The objective dry eye syndrome signs significantly increased with age. Based on the findings, the prevalence of dry eye syndrome in the studied population is in the mid-range. The prevalence is higher in women. Also, objective tests tend to turn abnormal at higher age. Pterygium is associated with dry eye syndrome and increased its symptoms. © 2013 Royal Australian and New Zealand College of Ophthalmologists.

    Full Text Available Robert Sambursky Coastal Eye Institute, Cornea and Comprehensive Ophthalmology, Bradenton, FL, USA Background: The presence of clinically significant inflammation has been confirmed in the tears of 40%–65% of patients with symptoms of dry eye. Ocular surface inflammation may lead to tear film instability, epithelial cell irregularities, and permeability, resulting in chronic symptomatic pain and fluctuating vision as well as negative surgical outcomes.Patients and methods: A retrospective single center medical chart review of 100 patients was conducted. All patients were tested with the InflammaDry test to determine if patients exhibited elevated levels of matrix metalloproteinase 9 (MMP-9. InflammaDry-positive patients were started on a combination of cyclosporine 0.05% twice daily, 2,000–4,000 mg oral omega-3 fatty acids, and frequent artificial tear replacement. InflammaDry-negative patients were started on 2,000–4,000 mg of oral omega-3 fatty acids and frequent artificial tear replacement. Each patient was retested at ~90 days. A symptom questionnaire was performed at the initial visit and at 90 days.Results: 60% of the patients with dry eye symptoms tested positive for elevated MMP-9 at the initial visit. 78% of all patients returned for follow-up at ~90 days including 80% (48/60 of the previously InflammaDry-positive patients and 75% (30/40 of the previously InflammaDry-negative patients. A follow-up symptom questionnaire reported at least 75% symptomatic improvement in 65% (31/48 of the originally InflammaDry-positive patients and in 70% (21/30 of the initially InflammaDry-negative patients. Symptomatic improvement of at least 50% was reported in 85% (41/48 of previously InflammaDry-positive patients and 86% (26/30 of previously InflammaDry-negative patients. Following treatment, 54% (26/48 of previously InflammaDry-positive patients converted to a negative InflammaDry result.Conclusion: Identifying which symptomatic dry eye

    Purpose: To determine if chronic graft-versus-host disease (cGVHD) after allogeneic hematopoietic stem cell transplantation (HSCT) is associated with stable or progressive dry eye disease and to determine the true incidence in patients with no prior history of dry eye disease. Methods: A nonconcurrent cohort study at a single institution with 136 patients who had no previous history of dry eye disease before HSCT. Survival analysis was used to estimate dry eye disease incidence. The incidence rate was calculated using life tables as the number of observed dry eye disease cases divided by the person-time at risk accumulated by the cohort. Transition probabilities were calculated from time of transplant to time of diagnosis, and then to last recorded visit. Results: Incidence rate was 0.8 cases of dry eye disease per person-year, and half of the population at risk developed dry eye disease during the first 10 months post transplant. Time to develop dry eye disease was 2.5 months for mild dry eye disease, 9.6 months for moderate dry eye disease, and 13.2 months for severe dry eye disease. In terms of cumulative incidence, 73% of subjects developed dry eye disease (50% mild, 16% moderate, and 7% severe) at the time of diagnosis. Conclusions: Our findings suggest that dry eye disease associated with cGVHD is an extremely frequent event and shows a wide spectrum of severity, with a mild form presenting early and a moderate to severe form presenting later after HSCT. These findings need to be studied further to elucidate if these are two different pathophysiological entities or just different expressions of the same pathology. PMID:27507907

    2017-11-01

    Dry eye disease (DED) represents a heterogeneous group of conditions with tear film insufficiency and signs and/or symptoms of ocular surface irritation. The clinical manifestations of DED can be highly variable; hence the diagnosis is often based on a combination of symptoms, signs, and clinical tests, given that any one of these alone would miss a significant number of patients. Similarly, the treatment must often be tailored to each patient by targeting the specific mechanisms involved in his or her disease. The purpose of this review is to summarize recent advances that have allowed us to better recognize, categorize, and treat patients with DED. The most notable new diagnostic tests in DED are tear film osmolarity, inflammatory biomarkers, and meibomian gland imaging. Therapeutically, anti-inflammatory therapy, meibomian gland heating and expression, and scleral contact lenses are some of the latest options available for treating DED.

    PurposeDry eye syndrome (DES) causes significant morbidity. Trials of blood-derived products in treatment of the condition show promising results. However, their production is expensive and time-consuming. We investigate fingerprick autologous blood (FAB) as an alternative low-cost, readily accessible treatment for DES.Patients and methodsProspective, non-comparative, interventional case series. In total, 29 eyes of 16 DES patients (2 males and 14 females) from two NHS sites in the United Kingdom. Patients instructed to clean a finger, prick with a blood lancet, and apply a drop of blood to the lower fornix of the affected eye(s), 4 times daily for 8 weeks then stop and review 4 weeks later. Follow-up visits occurred ~3 days, 2, 4, 8 weeks into therapy, and 4 weeks post-cessation. At each visit, visual acuity, corneal staining, Schirmer's test, tear break-up time (TBUT), and ocular comfort index (OCI) were measured, and photographs taken. Results were analysed using Student's paired t-test.ResultsAt 8 weeks, there was improvement in mean Oxford corneal staining grade (3.31 to 2.07 (P<0.0001)), TBUT (5.00 to 7.80 s (P<0.05)), visual acuity (0.08 to 0.01 LogMAR equivalent (P<0.05)), and OCI score (56.03 to 39.72 (P<0.0001)). There was no statistically significant change in Schirmer's test results. Four weeks post-cessation versus immediately after completion of FAB therapy, mean staining grade worsened from 2.07 to 2.86 (P<0.0001). OCI score worsened from 39.72 to 44.67 (P<0.05).ConclusionsIn our limited case series FAB appears to be a safe and effective treatment for DES.

    The purpose of this paper is to review the possible role of polypharmacy in causing dry eye disease (DED), reflecting the complex interactions and complications associated with the use of multiple systemic and topical ocular medications. The pharmacological, physiological, anatomical, and histological mechanisms causing dry mouth differ little from those causing dry eye. Oral polypharmacy is the most common cause of dry mouth, but has not been investigated as a cause of dry eye. Topical ocular polypharmacy has been shown to cause DED. Information on drugs that likely cause or aggravate DED and the controversial role of preservatives in topical ocular medications are examined. Systemic or topical ocular medications and preservatives used in topical ocular drugs may cause dry eye through the drug's therapeutic action, ocular surface effects, or preservatives, and the effects probably are additive. Long-term use of topical ocular medications, especially those containing preservatives such as BAK, may play an important role in DED and the role of polypharmacy needs further study. We review possible ways to decrease the risk of medication-related dry eye. PMID:23050121

    Objective: To compare the efficacy of 0.05 percent cyclosporine eye drops with 0.1 percentage fluromethalone eye drops on keratoconjunctivitis sicca (dry eye disease). Study Design: Randomized controlled trial. Place and Duration of Study: Ophthalmology department of HIT Hospital Taxila, from Oct 2014 to May 2015. Material and Methods: The patients with keratoconjunctivitis sicca (KCS) were selected from outpatient and divided in two treatment groups. The dry eye disease was defined according to criteria set by International task force for dry eye disease (ITF). The group I was treated with 0.05 percent cyclosporine drops while group-II was treated with 0.1 percent fluromethalone eye drops three times a day after informed written consent. The patients were followed up after three months and six months. Results: At the start of treatment 94 patients were placed in two treatment groups (n=47 in each group) and all the patients with KCS were graded according to severity following rules set by ITF. There were 46 patients in grade III (severe) KCS and 20 patients in grade IV (very severe) KCS. At the end of study only 24 were in grade II (moderate) KCS and 2 in grade III KCS. Of these only 5 patients in grade II and none in grade III were in treatment group I (cyclosporine). The remaining 19 patients in grade II and 5 patients in grade III KCS belonged to group II (fluromethalone). Conclusion: Cyclosporine eye drops are better than fluromethalone in treatment of keratoconjunctivitis sicca. (author)

    Outcomes-based review of reported treatment options for patients with dry eye secondary to Sjögren's syndrome (SS). Dry eye affects many individuals worldwide. Significant proportion of patients with dry eye has underlying SS, a progressive autoimmune condition. The few suggested guidelines for the treatment of dry eye are mostly based on severity of symptoms and/or clinical findings rather than on outcomes analysis, and do not differentiate SS from other causes of dry eye. METHODS AND LITERATURE REVIEW: A search strategy was developed to identify prospective, interventional studies of treatments for SS-associated dry eye from electronic databases. Eligible references were restricted to English-language articles published after 1975. These sources were augmented by hand searches of reference lists from accessed articles. Study selection, data extraction, and grading of evidence were completed independently by ≥4 review authors. The searches identified 3559 references as of August 10, 2010. After duplicate review of the titles and abstracts, 245 full-text papers were assessed, 62 of which were relevant for inclusion in the review. In the current literature on SS-associated dry eye, there is a paucity of rigorous clinical trials to support therapy recommendations. Nonetheless, the recommended treatments include topical lubricants, topical anti-inflammatory therapy, and tear-conserving strategies. The efficacy of oral secretagogues seems greater in the treatment of oral dryness than ocular dryness. Although oral hydroxychloroquine is commonly prescribed to patients with SS to alleviate fatigue and arthralgias, the literature lacks strong evidence for the efficacy of this treatment for dry eye.

    Advances in orbital radiotherapy have significantly increased therapeutic efficiency and reduced the side effects but a significant proportion of patients are still seen with ophthalmic complication like dry eye syndrome (DES). The treatment of DES involves temporary palliative therapies like ocular surface lubrication and rehydration. We aimed at establishing the human lacrimal gland cultures and evaluating for the presence of stem cells and secretory potential. Using human lacrimal gland tissues obtained from samples of therapeutic exenteration post-radiotherapy, we established a monolayer as well as 3D lacrispheres that show evidence of stem cells, secretory acinar cells, duct like formation and other cells like myoepithelial cells and duct like cells. The stem cells were identified as CD 117 positive that co-segregated with G0/G1 phase, ALDH high, label retaining cells and high clone forming ability. The most promising evidence of its secretory function was seen in the presence of tear substances like lysosymes, lactiferrin, and scIg A in the conditioned media of the lacrimal gland cultures. This novel development would pave way for development of a functionally competent 3D construct for potential clinical application in severe cases of radiation induced dry eye. (author)

    Dry eye disease is a multifactorial disease affecting the lacrimal functional unit and which has a significant impact on the quality of life of patients. This pathology works as a vicious circle at the ocular surface in which hyperosmolarity of the tear film plays a key role. This review intends to describe the different reported intracellular effects induced by hyperosmolarity in cells: alteration of cytoskeleton, cell cycle slowdown, adaptation mechanisms triggered as restoration of cell volume and accumulation of compatible osmolytes, the crucial role of the osmoprotectant factor Nuclear Factor of the Activated T cells-5 (NFAT5), apoptosis, as well as oxidative stress and inflammatory responses caused by this particular condition. Reported effects of hyperosmolarity in the experimental studies specific of dry eye disease concerning ocular surface cells will be described in parallel. Indeed, these data allow to understand a part of the pathophysiology of the disease, and specially the links between tear hyperosmolarity and inflammation of the ocular surface, the second key of the pathology phenomenon.

    To evaluate the preliminary long-term efficacy of diquafosol ophthalmic solution for aqueous-deficient dry eye. Fifteen patients with mild-to-moderate aqueous-deficient dry eye were enrolled. After a washout period, the patients were treated with 3 % diquafosol ophthalmic solution for 6 months. We assessed 12 subjective dry eye symptoms, corneal and conjunctival staining with fluorescein, tear film break-up time (BUT), lower tear meniscus height measured with anterior-segment optical coherence tomography, Schirmer's testing, and adverse reactions at baseline and 1, 3, and 6 months after the start of treatment. Treatment with diquafosol ophthalmic solution significantly improved dry eye symptoms, corneal staining, BUT, and tear meniscus height at 1 month and maintained the effectiveness for 6 months. Conjunctival staining significantly improved 3 and 6 months after treatment. No significant adverse reactions developed. Prolonged use of diquafosol ophthalmic solution for 6 months produced significant improvement both subjectively (dry eye symptom score) and objectively (ocular staining score and tear function tests) for aqueous-deficient dry eye.

    The dry eye syndrome is a common eye symptom causing blurry vision. To meet the demand of the modem world students and professionals are compelled to expose themselves to the computer screen for long stretch of time, which is one of the causes of dry eye. It is not always feasible to instil eyes with artificial tears time to time to protect them from dryness. Rather to adopt any simple physiological process associated with optimum lacrimation is a better option to keep eyes moist during computer works. Volunteers (n = 22) having mild dry eyes participated in this study. Tear production was assessed by Schirmer test by keeping Schirmer strip on ocular surface for 5 minutes and recording the length of the moistened area. Then the subject was allowed to keep a piece of lopsy candy (a sour fruit pulp mixed with sugar that is sweet and sour in taste) in mouth for 5 minutes that caused salivation. During salivation, again tear production was assessed. [It was standardized in such a way that, the length of the moistened strip will be 25 - 30 mm for normal eyes, 15 - 10 mm for dry eye, 06 - 10 mm for mild dry eye, 02 - 05 mm for moderate dryness and 00 - 01 mm for severe dry eye.] Tear production was found to be increased significantly (supported by increased length of moistened area of Schirmer strip) during salivation especially in dry eye in all volunteers. The lacrimal gland is the major contributor to the aqueous layer of the tear film which consists of water, electrolytes and proteins; secretion of which are under tight neural control. Anticholinergic agents play an important role in ocular dryness because of hypo-secretion. The sensory root of facial nucleus contains efferent preganglionic parasympathetic fibers for submandibular and sublingual salivary gland and lacrimal gland. The sensory root conveys gustatory fibers from the presulcul area (anterior two-third) of the tongue via the chorda tympani and via the palatine and greater petrosal nerve, taste fibers from

  17. The potential role of neuropathic mechanisms in dry eye syndromes.

    Science.gov (United States)

    Mcmonnies, Charles W

    Dry eye syndromes can involve both nociceptive and neuropathic symptoms. Nociceptive symptoms are the normal physiological responses to noxious stimuli. Neuropathic symptoms are caused by a lesion or disease of the somatosensory nervous system and can be the result of hypersensitisation of peripheral or central corneal and conjunctival somatosensory nerves. For example, inflammation could induce neuroplastic peripheral sensitisation of the ocular surface or lid wiper and exacerbate nociceptive symptoms. Neuropathic symptoms may explain the incommensurate relation between signs and symptoms in some dry eye syndromes although absence of signs of a dry eye syndrome may also be a consequence of inappropriate methods used when examining for them. Involvement of neuropathic mechanisms may also help explain dry eye symptoms which occur in association with reduced corneal sensitivity. This review includes a discussion of the potential for ocular symptoms involving neuropathic mechanisms to contribute to psychosocial problems such as depression, stress, anxiety and sleep disorders as well as for these types of psychosocial problems to contribute to neuropathic mechanisms and dry eye syndromes. Failure to consider the possibility that neuropathic mechanisms can contribute to dry eye syndromes may reduce accuracy of diagnosis and the suitability of treatment provided. Dry eye symptoms in the absence of commensurate evidence of tear dysfunction, and unsatisfactory response to tear dysfunction therapies should prompt consideration of neuropathic mechanisms being involved. Symptoms which persist after local anaesthetic instillation are more likely to be neuropathic in origin. Reducing inflammation may help limit any associated neuroplastic hypersensitivity.

    To estimate the prevalence and risk factors of symptomatic dry eye disease (DED) among undergraduate students in a Ghanaian university. This cross-sectional study included 700 undergraduate students of the University of Cape Coast, aged 18 to 34 years. Participants completed questionnaires delivered directly to randomly and systematically selected subjects to detect symptomatic dry eye and its predictive factors. Symptomatic dry eye was defined as any reported symptom on the Standard Patient Evaluation Eye Dryness (SPEED) questionnaire reported as often or constant or if any symptom on the Ocular Surface Disease Index (OSDI) was reported as most of the time or all of the time. Furthermore, OSDI ≥13 and SPEED ≥6 were used to defined symptomatic dry eye and prevalence were also estimated with these criteria as secondary measures. Current symptoms of dry eye and possible risk factors such as age, gender, current alcohol drinking, use of oral contraceptives, use of computer more than an hour daily, environmental conditions, allergies, and self-medication with over-the-counter eye drops were the main outcome measures. We used logistic regression analysis to examine the associations between dry eye and its predictive factors. Of the 700 participants, 650 completed the questionnaire. The prevalence of symptomatic dry eye was 44.3% (95% confidence interval [CI], 40.6%-48.2%). There was a significant association between symptomatic dry eye and discomfort with eyes in windy conditions (χ=110.1; df=4; Peye drops (OR 4.20; 95% CI, 2.61-6.74; Pdry eye. Sex was predictive in univariate analysis but was not significantly associated in multivariate analysis. The prevalence of symptomatic dry eye among undergraduate students in Ghana is high and it is associated with self-medication with over-the-counter eye drops, allergies, use of oral contraceptive, windy conditions, very low humid areas, air-conditioned rooms, and sex.

    To investigate the morphology, distribution, and density of inflammatory cells in the corneal epithelium of aqueous tear-deficient dry eye. Thirty-two patients with non-Sjögren's syndrome (NSS) dry eye, 14 patients with Sjögren's syndrome (SS) dry eye, and 33 healthy volunteers were studied. In vivo laser scanning confocal microscopy was used to investigate both Langerhans cell (LCs) and leukocyte distribution and density in the peripheral and central corneal epithelium. LC morphology was also evaluated. Multifactor regression analysis assessed whether there is a correlation between clinical manifestations and inflammatory cell densities. LCs were present in both central (34.9 +/- 5.7 cells/mm(2)) and peripheral (90.7 +/- 8.2 cells/mm(2)) parts of the normal corneal epithelium. Moreover, LC density increased dramatically in the central corneal epithelium in patients with NSS (89.8 +/- 10.8 cells/mm(2)) and SS (127.9 +/- 23.7 cells/mm(2)). The ratio of LCs with obvious processes was much higher in patients with dry eye than in healthy volunteers. LC density also increased in peripheral corneal epithelium in patients with SS, but not in those with NSS. Leukocyte density in normal corneal epithelium was very low, whereas it increased in the central corneal epithelium (4.6 +/- 1.0 cells/mm(2)) in NSS and in both central (49.0 +/- 12.9 cells/mm(2)) and peripheral (84.2 +/- 36.8 cells/mm(2)) corneal epithelium in SS. Densities of LCs and leukocytes showed significant correlation with the severity found in clinical evaluation. The LC and leukocyte changes in the corneal epithelium suggest their involvement in aqueous tear-deficient dry eye pathophysiology. In vivo dynamic assessment of central corneal inflammatory cell density may serve as an indicator of dry eye severity and provide new insight for dry eye treatment.

    The essential targets of dry eye disease (DED) treatments include both objective signs and subjective symptoms. However, due to the numerous subjective symptoms, it is understandable why little association has been found between the signs and symptoms. Although psychological influences on the subjective symptoms have been reported, little is known about the influence of personality traits. The present study analyzed the relationship between the signs/symptoms of DED and the personality traits of patients using a cross-sectional design. We examined 56 DED patients (mean age; 62.4 ± 12.9, range 34-85 years) visiting the outpatient clinic of the Department of Ophthalmology at the Nippon Medical School Hospital in Tokyo, Japan. Objective signs evaluated included the Schirmer I test, tear breakup time (BUT), fluorescein and lissamine green staining, and tear osmolality. Subjective symptoms were assessed by the Ocular Surface Disease Index (OSDI) and Dry Eye-Related Quality-of-Life Score (DEQS) questionnaires. For personality traits, the Big Five personality traits model analysis was used. Correlations between the objective signs, subjective symptoms, and personality traits were analyzed. A significant correlation was found between the neuroticism in the Big Five Personality Inventory and the symptoms assessed by the DEQS (r = -0.35, p personality traits. The results of our current study suggest that the personality of the patient, which appears to be the basis of various psychological factors, can have some impact on the subjective symptoms. This may be one of the reasons why there has been little association noted between the signs and symptoms of DED.

    We presented a case of refractory dry eye management with semi-scleral contact lens. Dry eye was associated with facial nerve (cranial nerve VII) palsy as a result of cerebellopontine angle tumor surgery. She was treated with several topical treatments and punctal plug. Despite the treatments, her symptoms still persisted. Her ophthalmic examination revealed scleral exposure because of lagophthalmos, conjunctival hyperemia, corneal debris, scar, and diffuse punctate epitheliopathy on her right eye. Lissamine green staining showed diffuse conjunctival and corneal staining. Therapeutic semi-scleral lenses were fitted. The corneal findings were resolved and the quality of patient life was improved with the aid of semi-scleral lens after 3 months.

    To describe new options for diagnosis and severity grading of dry eye disease. Perspective on technological advancements to identify tear dysfunction and their value in diagnosing and grading dry eye disease. Evidence is presented on new and evolving technologies to measure tear stability, composition, and meniscus height and their role in dry eye diagnosis and therapeutic efficacy grading is assessed. Evolving concepts regarding pathogenesis and new technologies to evaluate the tears and ocular surface have improved the ability to diagnose, classify, and grade the severity of dry eye disease. New technologies include noninvasive imaging of tear stability and tear meniscus height as a measure of tear volume and tear composition (osmolarity, lacrimal factors, inflammatory mediators, growth and differentiation factors). Approved tests, such as tear osmolarity and tear imaging, are being integrated into clinical practice and may eventually supplant certain traditional tests that have greater variability and less sensitivity. Other tests, such as molecular assays of tears and conjunctival cells, are currently being used in studies investigating pathogenesis and therapeutic mechanism of action. They may eventually translate to routine clinical practice. New technologies have emerged that can noninvasively evaluate the tears and measure disease-associated compositional changes. These tests are being integrated into clinical practice and therapeutic trials for diagnosis, classification, and severity grading of dry eye disease. Copyright © 2014 Elsevier Inc.

A retrospective clinical study was performed in patients with dry eye caused by SS. We evaluated the Schirmer test value, tear breakup time (tBUT), and fluorescein and Rose Bengal (RB) staining scores at baseline, 3 months, 6 months, 1 year, and >1 year after treatment. The dry eye indexes were also evaluated in 2 subgroups, which determined by the using of PPs, including the AS + PP group and AS only group. A total of 56 eyes of 28 patients were investigated with a mean follow-up of 42.3 ± 26.1 months. After the application of AS eye drops, the Schirmer test showed no significant changes. The tBUT (2.7 ± 1.9 seconds) was significantly improved at each time point (3.9 ± 3.1, 4.5 ± 3.1, 3.7 ± 2.5, and 5.1 ± 4.0; P eye drops was found to be an effective and apparently safe treatment for SS dry eye. Furthermore, PPs in combination with AS eye drops were considered to have an additive effect on SS dry eye.

    To investigate the effects of diquafosol sodium (DQS) eye drops, a purinergic P2Y2 receptor agonist, on tear film stability in patients with unstable tear film (UTF). Two prospective studies were conducted. One was an exploratory nonrandomized trial on 39 eyes with dry eye symptoms and short tear film break-up time (BUT), but without epithelial damage. Changes in symptoms, BUT, Schirmer value, and ocular surface fluorescein staining (FS) scores were studied for 3 months. The other was a randomized clinical trial of DQS and artificial tears (AT) in 17 eyes with short BUT. Eyes with decreased Schirmer values (≤ 5 mm) were excluded. Changes in symptoms, BUT, FS scores, and tear film stability using continuous corneal topographic analysis were studied for 4 weeks. In the exploratory study, while Schirmer values were not significantly increased, significant improvements in symptoms and BUT were noted at both 1 and 3 months. In the randomized clinical trial, significant improvements in symptoms were noted in the DQS group, but not in the AT group, at 2 weeks. BUT was significantly prolonged in the DQS group at 4 weeks but not in the AT group. No significant changes were noted in FS scores or tear film stability. DQS improved subjective symptoms and prolonged BUT in eyes with UTF not associated with low tear secretion and ocular surface epithelial damage. Because many patients who have UTF are refractory to conventional treatments, DQS may offer benefits in the treatment of dry eyes.

    The frequent lack of association between dry eye (DE) symptoms and signs leads to challenges in diagnosing and assessing the disease. Participants underwent ocular surface examinations to evaluate signs of disease and completed questionnaires to assess ocular symptoms, psychological status and medication use. To assess nociceptive system integrity, quantitative sensory testing (QST), including vibratory and thermal threshold measures and temporal summation of pain were obtained at the forearm and forehead. Correlations between DE discordance score (degree of discrepancy between symptom severity and DE signs) and patient characteristics were determined. Higher discordance scores indicated more symptoms than signs. 326 patients participated (mean age: 62 years; SD: 10 years; 92% men). Age was negatively correlated with DE discordance score (Pearson r=-0.30, p<0.0005), while mental health indices were positively correlated. Chronic pain elsewhere in the body (ie, non-ocular pain conditions) and intensity ratings of prolonged aftersensations of pain evoked by noxious hot and cold stimuli were also significantly correlated with DE discordance score. Multiple linear regression demonstrated that post-traumatic stress disorder and non-ocular pain intensity were important predictors of DE discordance score, Dry Eye Questionnaire-5 and Ocular Surface Disease Index and that DE discordance was also sensitive to QST as well. The present study provides evidence that the degree of discordance between DE symptom report and measurable signs of ocular surface disease is associated with comorbidities related to clinical pain and to hyperalgesia as demonstrated with QST. Understanding the epidemiology of DE discordance can aid in interpreting the DE exam and individualising treatment. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Full Text Available Dry eye is highly prevalent and has a significant impact on quality of life. Acupuncture was found to be effective to treat dry eye. However, little was known about the effect of acupuncture on different subtypes of dry eye. The objective of this study was to investigate the applicability of tear meniscus assessment by Fourier-domain optical coherence tomography in the evaluation of acupuncture treatment response in dry eye patients and to explore the effect of acupuncture on different subtypes of dry eye compared with artificial tear treatment. A total of 108 dry eye patients were randomized into acupuncture or artificial tear group. Each group was divided into three subgroups including lipid tear deficiency (LTD, Sjögren syndrome dry eye (SSDE, and non-Sjögren syndrome dry eye (Non-SSDE for data analysis. After 4-week treatment, the low tear meniscus parameters including tear meniscus height (TMH, tear meniscus depth (TMD, and tear meniscus area (TMA in the acupuncture group increased significantly for the LTD and Non-SSDE subgroups compared with both the baseline and the control groups (all P values < 0.05, but not for the SSDE. Acupuncture provided a measurable improvement of the tear meniscus dimensions for the Non-SSDE and LTD patients, but not for the SSDE patients.

    In this paper we have studied the thermal fluctuation patterns occurring at the ocular surface of the left and right eyes for aqueous deficient dry eye (ADDE) patients and control subjects by thermal imaging. We conducted our experiment on 42 patients (84 eyes) with aqueous deficient dry eyes and compared with 36 healthy volunteers (72 eyes) without any history of ocular surface disorder. Schirmer's test, Tear Break-up Time, tear Meniscus height and fluorescein staining tests were conducted. Ocular surface temperature measurement was done, using an FL-IR thermal camera and thermal fluctuation in left and right eyes was calculated and analyzed using MATLAB. The time series containing the sum of squares of the temperature fluctuation on the ocular surface were compared for aqueous deficient dry eye and control subjects. Significant statistical difference between the fluctuation patterns for control and ADDE was observed (p eyes are significantly correlated in controls but not in ADDE subjects. The possible origin of such correlation in control and lack of correlation in the ADDE subjects is discussed in the text. Copyright © 2014 Elsevier Ltd. All rights reserved.

    The aim of this study was to determine the prevalence and severity of dry eye syndrome in a group of Mexican residents of different surgical specialties. A cross-sectional descriptive study where the residents were studied using the Ocular Surface Disease Index, together with diagnostic tests for dry eye syndrome, such as tear breakup time, Oxford Schema, Schirmer's test I, and meibomian gland dysfunction testing. Statistical analyses were performed by Pearson's chi-squared test for categorical variables and student's t-test for quantitative variables. Any P value eyes); 90 (73 %) were male and 33 (27 %) were female. The mean age was 27.8 ± 2.1 years. A higher number of residents with dry eye syndrome was found in the cardiothoracic surgery (75 %) and otorhinolaryngology (71 %) specialties; 70 % of them reported ocular symptoms, with teardrop quality involvement in >50 % of them. We found a prevalence of 56 % for mild-to-moderate/severe stages of the condition. Their presence in the operating room predisposes surgical residents to dry eye syndrome because of environmental conditions.

    To evaluate the efficacy of botulinum toxin type A injection to cause orbicularis eyelid muscle paralysis to improve dry eye signs and symptoms. A prospective, randomized, comparative eye-to-eye and interventional study was performed. Patients with dry eye symptoms and positive fluorescein corneal staining were included. Randomly one eyelid received a subcutaneous injection of botulinum toxin in the medial orbicularis muscle portion of the lower eyelid, and the other eye received placebo. The subjective evaluation was achieved with a questionnaire assessing symptoms, quality of vision and ocular comfort level. The objective evaluation included the measurement of the tear film break-up time (TBUT), Schirmer's test and corneal and conjunctival staining. Twenty patients were included with a mean age of 59.5 years. Two weeks after the botulinum toxin injection, all patients showed a decrease in the horizontal movement of the lower eyelid when blinking. The eyes in the active treatment group showed better scores compared with the sham group in four symptoms 4 weeks after the treatment. The TBUT was higher at 1 and 3 months in the active treatment group. The corneal and conjunctival staining were significantly lower in the active treatment group at 1 and 3 months, and the Schirmer's test showed better measurements in the same group at 2 weeks, 1 month and 3 months. There were no adverse events reported. The injection of botulinum toxin A in the medial part of the lower eyelid is an effective and safe procedure that temporally improves some of the signs and symptoms of patients with dry eye. © 2016 Acta Ophthalmologica Scandinavica Foundation.

    The aim of this study was to evaluate the treatment effect of diquafosol 3% with preservative-free sodium hyaluronate 0.1% eye drops in dry eye syndrome. In total, 150 patients with dry eye syndrome were divided randomly into 3 groups. Group 1 (50 patients) was treated 4 times daily with preserved sodium hyaluronate 0.1%, group 2 (50 patients) was treated 4 times daily with diquafosol 3%, and group 3 (50 patients) was treated 4 times daily with diquafosol 3% and preservative-free sodium hyaluronate 0.1% eye drops for 3 months. Ocular surface disease index (OSDI) score, tear film break-up time, Schirmer I test, corneal fluorescein staining, and impression cytology were evaluated. There were significant improvements in the OSDI score, tear film break-up time, Schirmer I score, fluorescein and Rose Bengal staining, goblet cell density, and impression cytological findings in groups 2 and 3 compared with those for group 1 in patients with dry eye syndrome at 1, 2, and 3 months (P dry eye syndrome. Preservative-free sodium hyaluronate 0.1% eye drops can increase the effect of diquafosol 3% in dry eye syndrome.

    The aim of this study is to investigate the effect of pseudoexfoliation (PEX) and PEX-induced dry eye on central corneal thickness (CCT). This cross-sectional study consists of total 270 eyes of 135 patients (67 females, 68 males) in total. After excluding the PEX (-) 32 eyes with PEX in the other eye, totally 130 eyes in PEX (-) group and 108 eyes in the PEX (+) group were included in the study. The PEX (+) group was regrouped as PEX syndrome (80 eyes of 50 patients) and PEX glaucoma (28 eyes of 20 patients). In the PEX (-) group, the mean Schirmer test result was 12 ± 4 mm (4-25 mm), in the PEX syndrome group 10 ± 4 mm (4-22 mm), in the PEX glaucoma group 9 ± 3 mm (4-15 mm). The difference among the PEX (-) group, the PEX syndrome and the PEX glaucoma groups was statistically significant (p eyes with PEX (r = 0.307, p = 0.001). However, there was no statistically significant correlation between CCT, Schirmer and tear break up time tests in the eyes with PEX. PEX material can cause decrease in tear film secretion and disturb tear film stability. There is no effect of PEX-induced dry eye on CCT. Lower CCT values in the eyes with PEX material may be a result of decrease in corneal stromal cell density. Moreover, higher CCT values may be because of decreased endothelial cells in PEX glaucoma patients.

    To evaluate the prevalence, severity, and effect of dry eye in patients after allogeneic hematopoietic stem cell transplantation (aHSCT) and to correlate the findings to the duration after transplantation. A total of 222 eyes of 111 patients after aHSCT at the Department of Bone Marrow Transplantation, Sheba Medical Center, Israel in a consecutive 3-year period. All patients underwent a full ophthalmic examination and filled the ocular surface disease index (OSDI) questionnaire to assess ocular involvement in the form of dry eye syndrome or any other ocular manifestation. The main outcome measures were best-corrected visual acuity, tear break-up time, corneal fluorescein staining, Schirmer test, and OSDI questionnaire. A total of 111 patients were recruited. In 37%, a diagnosis of ocular graft versus host disease was previously made and 46% had no previous ocular examination. Schirmer test was less than 5 mm in 50% of all patients, and in 30% of patients with undiagnosed ocular involvement. The mean OSDI score was 13, and in 28% it was above 20. Correlation was found between visual acuity decrease and high OSDI score to the diagnosis of ocular graft versus host disease and signs of dry eye syndrome. A trend of worsening dry eye was observed up to the second half of the second year posttransplantation. Although many patients are either asymptomatic or do not seek ophthalmic examination, severe dry eye is a common finding after aHSCT. Mandatory follow-up, patient education, and early treatment may improve the quality of life.

METHODS:Totally 200 patients with dry eye were randomly divided into the control group(n=100and observation group(n=100. Patients in two groups were given 3g/L sodium hyaluronate eye drops and physiotherapy. On the basis of this, the observation group were treated with bromhexine hydrochloride tablets. The inflammatory factors(IL-6, IL-10, TNF-α and IL-1βlevels and ocular symptom scores(OSDI, BUT, SⅠt, FLin the two groups were compared between before and after treatment. And the clinical efficacy and adverse reactions were evaluated. RESULTS: After treatment, the IL-6, IL-10, TNF-α, IL-1β, OSDI and FL scores in two groups were significantly lower than those before treatment, and BUT and SⅠt were significantly higher than those before treatment. Moreover, the improvement degree of the above indexes in the observation group were better than those in the control group, showing statistically significant difference(Pχ2=5.531, P=0.019, but there was no significant difference in the incidence of adverse reactions between the two groups(χ2=0.307, P=0.579. CONCLUSION:As for the patients with dry eye, the combination of 3g/L sodium hyaluronate eye drops with bromhexine hydrochloride tablets can significantly decrease the level of inflammatory factors, improve the eye symptoms and the clinical total efficiency, without increasing treatment-related adverse effects.

    The study aimed to investigate the effects of silk fibroin in a mouse model of dry eye. The experimental dry eye mouse model was developed using more than twelve-weeks-old NOD.B10.H2b mice exposing them to 30-40% ambient humidity and injecting them with scopolamine hydrobromide for 10 days. Tear production and corneal irregularity score were measured by the instillation of phosphate buffered saline or silk fibroin. Corneal detachment and conjunctival goblet cell density were observed by hematoxylin and eosin or periodic acid Schiff staining in the cornea or conjunctiva. The expression of inflammatory markers was detected by immunohistochemistry in the lacrimal gland. The silk group tear production was increased, and corneal smoothness was improved. The corneal epithelial cells and conjunctival goblet cells were recovered in the silk groups. The expression of inflammatory factors was inhibited in the lacrimal gland of the silk group. These results show that silk fibroin improved the cornea, conjunctiva, and lacrimal gland in the mouse model of dry eye. These findings suggest that silk fibroin has anti-inflammatory effects in the experimental models of dry eye.

    Dry eye is a common disorder caused by inadequate hydration of the ocular surface that results in disruption of barrier function. The homeostatic protein clusterin (CLU) is prominent at fluid-tissue interfaces throughout the body. CLU levels are reduced at the ocular surface in human inflammatory disorders that manifest as severe dry eye, as well as in a preclinical mouse model for desiccating stress that mimics dry eye. Using this mouse model, we show here that CLU prevents and ameliorates ocular surface barrier disruption by a remarkable sealing mechanism dependent on attainment of a critical all-or-none concentration. When the CLU level drops below the critical all-or-none threshold, the barrier becomes vulnerable to desiccating stress. CLU binds selectively to the ocular surface subjected to desiccating stress in vivo, and in vitro to the galectin LGALS3, a key barrier component. Positioned in this way, CLU not only physically seals the ocular surface barrier, but it also protects the barrier cells and prevents further damage to barrier structure. These findings define a fundamentally new mechanism for ocular surface protection and suggest CLU as a biotherapeutic for dry eye.

    Our objective was to investigate the hypothesis that women on adjuvant aromatase inhibitors (AIs) for treatment of breast cancer have a higher prevalence of dry eye syndrome (DES) compared with controls. Exposure and control groups were recruited. A cross sectional questionnaire-based study was performed. Demographic data and medical histories were collected. The presence of dry eye syndrome was determined by the ocular surface disease index (OSDI). The Functional Assessment of Cancer Treatment - Endocrine Subscale (FACT-ES) was performed to investigate correlations with other side effects of AIs. 93 exposure group and 100 control group questionnaires were included. The groups were similar in all demographic variables. The prevalence of dry eye syndrome was 35% (exposure) and 18% (control) (p dry eyes. The OSDI score was negatively correlated with the total FACT-ES score and positively correlated with duration of treatment. Our study is the first to use a validated questionnaire to assess for DES in this population. DES is significantly more prevalent in women on AIs compared with controls. This is a newly emerging, and easily treated side effect of AIs. Self-reporting of dry eye symptoms underestimates the prevalence of DES with AIs. We recommend routine screening of patients on AIs with the OSDI with the aim of improving patient quality of life and possibly adherence. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Symptoms of dry eye are commonly reported in contact lens wearers and are a frequent cause of non-tolerance. The purpose of the present study is to evaluate the effects of oral treatment with particular omega-6 fatty acids in the form of evening primrose oil (EPO) on subjective symptoms, ocular surface signs and tear film characteristic in patients with contact lens associated dry eye. The study design was randomised, double-masked and placebo controlled. 76 female soft contact lens wearers were treated for 6 months with either EPO or placebo (olive oil). Subjects underwent three examinations (baseline, 3 and 6 months). At each examination subjects were given a questionnaire relating to lens comfort and dry eye symptoms and underwent a series of tests of tear film characteristics (tear meniscus height, break-up time), meibomian gland function (lipid layer thickness and quality) and ocular surface parameters (hyperaemia and staining). The EPO group showed a significant improvement in the specific symptom of 'dryness' at 3 and 6 months (porally administered omega-6 fatty acids in alleviating dry eye symptoms and improving overall lens comfort in patients suffering from contact lens associated dry eye.

    Full Text Available AIM: To determine the role of subjective assessment using McMonnies dry eye questionnaire in diagnosing dry eye disease and its association with clinical tests. METHODS: There were 500 patients screened for dry eye using McMonnies dry eye questionnaire between May to October 2013 at the outpatient Department of Ophthalmology of a medical college hospital. All 500 patients were subjected to clinical tests. Dry eye was defined as having one or more symptoms often or all the time. Positive signs were if one or both eyes revealed tear film breakup time (TBUT of ≤10s, a Schirmer test score of ≤10 mm, a Rose Bengal staining score of ≥1, a Lissamine green staining score of ≥1 or existence of meibomian gland disease (≥grade 1. Statistical analysis was performed to describe the distribution of symptoms and signs, to assess the correlations between McMonnies score (MS and variable clinical signs of dry eye, and to explore the association between dry eye symptoms and variable clinical signs. Analysis was performed using software package Epi info. A Probability (P value using Chi-square test of RESULTS: Dry eye prevalence with symptoms (questionnaire, Schirmer test, TBUT, Rose Bengal staining and Lissamine green staining was 25.6%, 15.20%, 20.80%, 23.60%, and 22.60% respectively. Among those with severe symptoms (MS>20, 75.86% had a low TBUT (CONCLUSION: Subjective assessment plays an important role in diagnosing dry eye disease. There is strong correlation between MS and Schirmer test, TBUT, Rose Bengal staining and Lissamine green staining in normal as well as marginal and pathological dry eye.

    Animal models have proved valuable to investigate the pathogenesis of dry eye disease, identify therapeutic targets and the efficacy of candidate therapeutics for dry eye. Pharmacological inhibition of the lacrimal functional unit and exposure of the mouse eye to desiccating stress was found to activate innate immune pathways, promote dendritic cell maturation and initiate an adaptive T cell response to ocular surface antigens. Disease relevant mediators and pathways have been identified through use of genetically altered mice, specific inhibitors and adoptive transfer of desiccating stress primed CD4+ T cells to naïve recipients. Findings from mouse models have elucidated the mechanism of action of cyclosporine A and the rationale for developing lifitegrast, the two currently approved therapeutics in the US. PMID:28282318

    To assess the functional impact of the severity of dry eye on the quality of vision by measuring an Objective Scatter Index (OSI) using double pass aberrometry. Twenty-eight patients (56 eyes) with dry eye syndromes of varying severity participated in this study. A double-pass aberrometer was used to measure the dynamic changes in the OSI for 20 seconds. The mean and standard deviations of the OSI and the number of blinks occurring during the examination were compared as a function of the clinical severity of dry eye disease. The mean OSI increased with the severity of dry eye syndrome with a significant difference for stages 3 (P0.8) or visual acuity (P>0.2). Standard deviation of the OSI also increased with the severity of dry eye disease, with a significant difference for stages 3 (P0.2). The values of the OSI standard deviation represented the dynamic nature of aberrometric changes related to the instability of the tear film. Quality of vision of patients deteriorated in relation to the severity of their dry eye. The analysis of OSI standard deviation appears to be an objective way to assess the intensity of subjective visual disturbances reported by patients with dry eye syndrome. It also provides a new tool to assess the severity of damage to the ocular surface. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    Dry eye, a common yet underrecognized and evolving field, has few recommended treatment algorithms, mostly based on expert consensus rather than robust research evidence. There are high costs associated with managing dry eye and conducting research to identify effective and safe long-term treatments. To support evidence-based management of dry eye, our purpose was to identify and prioritize important clinical research questions for future clinical research. We translated recommendations from the American Academy of Ophthalmology's 2013 Preferred Practice Patterns for dry eye into answerable clinical research questions about treatment effectiveness. Clinicians around the world who manage patients with dry eye rated each question's importance from 0 (not important) to 10 (very important) using a 2-round online Delphi survey. We considered questions as "important" if ≥75% of respondents assigned a rating of 6 or more in round 2. We mapped the identified important clinical research questions to reliable systematic reviews published up to March 2016. Seventy-five clinicians from at least 21 countries completed both Delphi rounds. Among the 58 questions, 24 met our definition of "important": 9/24 and 7/24 addressed topical and systemic treatments, respectively. All 4 questions with the highest 25th percentiles addressed topical treatments. Although 6/24 "important" questions were associated with 4 existing reliable systematic reviews, none of these reviews came to a definitive conclusion about treatment effectiveness. We identified gaps pertaining to treatment options for dry eye. Future clinical research on the management of dry eye should strongly consider these prioritized questions.

Although anti-VEGF therapy has shown promising results for many patients, there are several aspects of its application that have not been thoroughly investigated. One of these is the development and/or escalation of concurrent dry eye syndrome. Many patients undergoing treatment are already predisposed to dry eye disease due to their age and overall ocular health. As dry eye can have a substantial impact on quality of life, it has become increasingly apparent that the clinical signs and symptoms should be closely monitored and aggressively managed. This will allow for the optimization of patient comfort and visual potential. Here, we discuss the reasons why dry eye may develop during the course of repeated ocular anti-VEGF therapy, highlighting the key concerns about current practices and proposing possible solutions to improve the outcome for the patients.

    Cataract surgery is one of the most frequently performed intra-ocular surgeries, of these manual Small Incision Cataract Surgery (SICS) is a time tested technique of cataract removal. Any corneal incisional surgery, including cataract surgery, can induce dry eye postoperatively. Various factors have been implicated, of which oneis the inflammation induced by the surgery. Lactoferrin, a glycoprotein present in tears is said to have anti-inflammatory effects, and promotes cell growth. It has been used orally in patients of immune mediated dry eye to alleviate symptoms. This study was aimed to evaluate the dry eyes induced by manual Small Incision Cataract Surgery, and the effect if any, of oral lactoferrin on the dry eyes. A single centre, prospective randomised controlled trial with a concurrent parallel design. The study was carried out on patients presenting in the OPD of Rohilkhand Medical College hospital for cataract surgery. Sixty four patients of cataract surgery were included in the study. Patients with pre-existing dry eyes, ocular disease or systemic disease predisposing to dry eyes were excluded from the study. The selected patients were assigned into two groups by simple randomisation-Control Group A-32 patients that did not receive oral lactoferrin postoperatively. Group B-32 patients that received oral lactoferrin 350 gm postoperatively from day 1 after SICS. All patients were operated for cataract and their pre and postoperative (on days 7, 14, 30 and 60) dry eye status was assessed using the mean tear film break-up time (tBUT) and Schirmer test 1 (ST 1) as the evaluating parameters. Subjective evaluation of dry eye was done using Ocular Surface Disease Index (OSDI) scoring. Data was analysed for 58 patients, as 6 did not complete the follow up. Unpaired t-test was used to calculate the p-values. There was a statistically significant difference between the tBUT values of the Control and Lactoferrin group from day 14 onwards.

    To identify systemic comorbidities in patients with dry eye syndrome in South Korea. From 2010 to 2012, 17,364 participants aged 20 or older were randomly included in the nationwide Korean National Health and Nutrition Examination Survey V. The prevalence of dry eye syndrome and demographics of these patients were investigated. We performed conditional logistic regression analyses based on age, sex, residential area, education level, occupation type, and household income level to obtain the odds ratio for each systemic comorbidity among subjects with and without dry eye syndrome. The prevalence of dry eye syndrome in this study was 10.4%. Age [adjusted odds ratio (AOR): 1.02], female gender (AOR: 3.01), and indoor occupation (AOR: 1.30) were associated with a higher prevalence of dry eye syndrome and found to be less prevalent in those residing in rural areas (AOR: 0.73) and with lower education levels (AOR: 0.66-0.99). With regard to systemic comorbidities, dyslipidemia (AOR: 1.63), degenerative arthritis (AOR: 1.56), rheumatoid arthritis (AOR: 1.44), thyroid disease (AOR: 1.79), and renal failure (AOR: 2.56) were associated with a significantly higher prevalence of dry eye syndrome. We found that patients with dry eye syndrome have a higher prevalence of several systemic comorbidities. A more comprehensive therapeutic approach considering the effect of systemic medication may be necessary in these patients.

    Dry eye disease has become an important health problem. A lack of concordance between self-reported symptoms and the outcome of dry eye examinations has raised questions about dry eye disease. To explore the association between subjective happiness and objective and subjective symptoms of dry eye disease. The study adopted a cross-sectional design. All the employees of a company in Osaka, Japan. 672 Japanese office workers using Visual Display Terminals (age range: 26-64 years). The dry eye measurement tools included the Schirmer test, conjunctivocorneal staining, the tear film break-up time, as well as the administration of a dry eye symptoms questionnaire. Happiness was measured by the Subjective Happiness Scale. Dry eye examination parameters, dry eye symptoms questionnaires, and the Subjective Happiness Scale score. Of the 672 workers, 561 (83.5%) completed the questionnaires and examinations. The mean Subjective Happiness Scale score was 4.91 (SD = 1.01). This score was inversely correlated with the dry eye symptom score (r = -0.188, p happiness was the lowest in the group without objective results, but reported subjective symptoms of dry eyes (p happiness and self-reported symptoms of dry eyes. Findings of this study revealed a new perspective on dry eye disease, including the potential for innovative treatments of a specific population with dry eye disease.

    To evaluate the clinical characteristics and management of short tear film breakup time (BUT) -type dry eye. Clinical background and post-treatment changes of symptoms in 77 patients with short BUT -type dry eye were investigated. Treatment consisted of artificial-tear eye-drop instillation and, if necessary, the addition of a low-density-level steroid, hyaluronic acid, a low-density-level cyclopentolate prepared by ourselves and punctal plugs inserted into the upper and lower lacrimal puncta. There were three times more women than men among the patients, and the peak age of occurrence was in the twenties in the men and in the sixties in the women. Our findings show that visual display terminal (VDT) work, contact lens (CL) wear, and changes in the sex hormones may initiate subjective symptoms. Some patients had simultaneous conjunctivochalasis, allergic conjunctivitis, and meibomian gland dysfunction. Nineteen patients (24.7%) were effectively treated with eye-drop instillation alone. Thirty-seven patients (48.1%) required punctal-plug insertion, which was completely effective in only 8 of them (21.6%). Mainly young men and menopausal women contract short BUT -type dry eye. Changes in sex hormones, VDT work and CL wear may be causal, and the disease cannot be controlled by eyedrop and punctal-plug treatment alone.

    Current dry eye treatment includes delivering comfort enhancing agents to the eye via eye drops, but low residence time of eye drops leads to low bioavailability. Frequent administration leads to incompliance in patients, so there is a great need for medical device such as contact lenses to treat dry eye. Studies in the past have demonstrated the efficacy of hyaluronic acid (HA) in the treatment of dry eyes using eye drops. In this paper, we present two methods to load HA in hydrogel contact lenses, soaking method and direct entrapment. The contact lenses were characterized by studying their optical and physical properties to determine their suitability as extended wear contact lenses. HA-laden hydrogel contact lenses prepared by soaking method showed release up to 48 h with acceptable physical and optical properties. Hydrogel contact lenses prepared by direct entrapment method showed significant sustained release in comparison to soaking method. HA entrapped in hydrogels resulted in reduction in % transmittance, sodium ion permeability and surface contact angle, while increase in % swelling. The impact on each of these properties was proportional to HA loading. The batch with 200-μg HA loading showed all acceptable values (parameters) for contact lens use. Results of cytotoxicity study indicated the safety of hydrogel contact lenses. In vivo pharmacokinetics studies in rabbit tear fluid showed dramatic increase in HA mean residence time and area under the curve with lenses in comparison to eye drop treatment. The study demonstrates the promising potential of delivering HA through contact lenses for the treatment of dry eye syndrome.

    Dry eye syndrome is a common chronic disease; agents and strategies for its effective management are still lacking. The syndrome tends to be accompanied by ocular surface inflammation; therefore, the use of anti-inflammatory agents might prove beneficial. The authors present up-to-date guidelines, strategies, and efficacy of dry eye syndrome management, including anti-inflammatory treatment. As no diagnostic tests are now available to assess ocular surface inflammation severity, the right timing to launch an anti-inflammatory agent is difficult to determine. Patients with mild intermittent bouts of symptoms which can be alleviated with ophthalmic lubricants do not typically require anti-inflammatory therapy. The latter should be considered in those who do not respond to lubricating drops, obtain poor results on clinical tests, and show symptoms of ocular surface irritation (eg. conjunctivae redness). Anti-inflammatory treatment of dry eye syndrome may include short-term corticosteroids, cyclosporine A emulsion, oral tetracycline therapy, oral omega-3 fatty acid supplements, and autologous serum eye drops. Anti-inflammatory treatment should be safe and effective; potential benefits should be evaluated for each individual patient. The authors have reviewed the advantages of anti-inflammatory treatment in dry eye syndrome, presented in literature.

    Full Text Available Shizuka Koh Department of Ophthalmology, Osaka University Graduate School of Medicine, Suita, Osaka, Japan Abstract: Diquafosol is a drug used for dry eye treatment with a novel mechanism of action. It stimulates the secretion of tear fluid and mucin on the ocular surface, thus enabling us to selectively treat the tear film layer, playing an important role in the establishment of the concept of “Tear Film Oriented Therapy (TFOT”, an effective therapeutic approach to dry eye in Japan. The 3% diquafosol ophthalmic solution has been widely used for the treatment of dry eye in clinical practice, and it is currently available in Japan and South Korea. This review provides an overview of the clinical utility of 3% diquafosol ophthalmic solution, focusing on the results of clinical studies on various types of dry eye, including aqueous-deficient dry eye, short tear film breakup time-type dry eye, and post dry eye after laser in situ keratomileusis. It also introduces the additive effect of diquafosol on sodium hyaluronate monotherapy for dry eye, and the effect of 3% diquafosol ophthalmic solution for dry eye-related conditions. Additionally, it summarizes the ocular effects of diquafosol in healthy human eyes. Lastly, the importance of improving tear film stability in dry eye treatment, as well as general advances in dry eye treatments, are described.

    To evaluate the performance of a point-of-care test for detection of matrix metalloproteinase 9 (MMP-9) levels in post-laser-assisted in situ keratomileusis (LASIK) dry eyes. A comparative study between patients with mild to moderate post-LASIK dry eyes and age-matched normal subjects was conducted. Ocular surface disease index (OSDI), tear break-up time (TBUT), and tear film MMP-9 and total protein levels were compared between the two groups. A point-of-care test device (RPS InflammaDry, Sarasota, Florida, USA) was utilised to confirm elevated MMP-9 levels in tear film. Fourteen post-LASIK dry eyes and 34 normal eyes were included. There was no significant difference in age and gender between both groups (p>0.175). The OSDI was significantly higher (25.5±7.7 vs 7.4±2.5; pdry eye compared with normal subjects. The tear film MMP-9 levels were 52.7±32.5 ng/mL in dry eyes and 4.1±2.1 ng/mL in normal eyes (p40 ng/mL in 7/14 (50.0%) post-LASIK dry eyes. The InflammaDry was positive in 8/14 (57.1%) post-LASIK eyes. All positive cases had tear film MMP-9 levels ≥38.03 ng/mL. Agreement between InflammaDry and MMP-9 was excellent with Cohen κ value of 0.857 in post-LASIK dry eyes. Only half of post-LASIK dry eyes were found to have significant inflammation associated with elevated MMP-9. The OSDI is useful to non-specifically identify patients with symptomatic dry eye while the InflammaDry determined which patients with dry eye were associated with significant inflammation that may guide therapeutic management decisions.

    To describe and compare the prevalence and characteristics of dry eye among Han and Uyghur persons living in Kashi, the most inland city of China. A total of 1015 residents of Kashi participated in this 2013 cross-sectional study. To evaluate clinical characteristics, each subject completed (1) a dry-eye questionnaire detailing symptoms of dry eye, (2) Schirmer's I-test (SIT), (3) tear-film break-up time (BUT) test, and fluorescein staining of the cornea. Dry eye was defined as the existence of dry eye symptoms and at least two positive clinical signs. Data were analyzed using SPSS software. The prevalence and risk factors of dry eye were evaluated using a multivariate model. Overall, 282 (27.8%) of the 1015 participants were diagnosed with dry eye (95% confidence interval (CI): range, 25.5-30.1). The prevalence of dry eye among Han persons (37.9 %) (95% CI: range, 35.8-40.0) was higher than that among Uyghurs (21.8%) (95% CI: 19.6-24.0) (p dry eye was 25.6% (95% CI: range, 23.3-27.8) among men and 28.7% (95% CI: 26.5-30.9) among women (p > 0.05). Risk factors for dry eye included ethnicity, age, occupation, arthritis, and dry mouth. Our study revealed a higher prevalence of dry eye among Han than Uyghur persons in Kashi. Dry eye was significantly associated with environment and ethnicity.

    To evaluate and compare the ocular surface condition in herpetic interstitial stromal keratitis and neurotrophic ulcer groups and their normal fellow eyes. In this observational, cross-sectional case-control study, 85 consecutive patients were included, including 56 cases of treated herpetic interstitial keratitis and 29 patients with neurotrophic ulcers. Fifty-six age- and sex-matched participants were also recruited from a normal population as the control group. We evaluated and scored the subjective and objective measures of dry eye for both eyes of all patients. Then, we compared the score of the groups with one another and also with the control group. The main outcome measures were the discomfort level, visual symptoms of dry eye, conjunctival injection, conjunctival staining, corneal staining, corneal tear signs of dry eye, meibomian gland dysfunction, tear break-up time, Schirmer test score with anesthesia, and tear osmolarity. The normal fellow eye of the herpetic keratitis group had significantly higher discomfort levels (1.4 ± 0.9 vs. 1.3 ± 0.5, P = 0.003), visual symptoms (1.7 ± 0.8 vs. 1.3 ± 0.7, P = 0.002), tear break-up time (8.3 ± 3.2 vs. 12.1 ± 3.3 seconds, P = 0.003), Schirmer test scores (9.2 ± 3.9 vs. 12.9 ± 3 mm, P = 0.04), and tear osmolarity (9.2 ± 3.9 vs. 12.9 ± 3 mm, P = 0.003) in comparison with normal controls. The normal fellow eyes of the neurotrophic ulcer group had significantly worse values for discomfort level (1.9 ± 0.9 vs. 1.3 ± 0.5, P eyes of patients with neurotrophic ulcer and interstitial herpetic keratitis have a significantly poorer ocular surface condition compared with that of normal controls.

    The purpose of this study was to determine the clinical benefits of intense-pulsed-light therapy for the treatment of dry-eye disease caused by meibomian gland dysfunction (MGD). MGD is the leading cause of evaporative dry eye disease. It is currently treated with a range of methods that have been shown to be only somewhat effective, leading to the need for advanced treatment options. A retrospective noncomparative interventional case series was conducted with 91 patients presenting with severe dry eye syndrome. Treatment included intense-pulsed-light therapy and gland expression at a single outpatient clinic over a 30-month study. Pre/post tear breakup time data were available for a subset of 78 patients. For all patients, a specially developed technique for the treatment of dry eye syndrome was applied as a series of monthly treatments until there was adequate improvement in dry eye syndrome symptoms by physician judgment, or until patient discontinuation. Primary outcomes included change in tear breakup time, self-reported patient satisfaction, and adverse events. Physician-judged improvement in dry eye tear breakup time was found for 68 of 78 patients (87%) with seven treatment visits and four maintenance visits on average (medians), and 93% of patients reported post-treatment satisfaction with degree of dry eye syndrome symptoms. Adverse events, most typically redness or swelling, were found for 13% of patients. No serious adverse events were found. Although preliminary, study results of intense-pulsed-light therapy treatment for dry eye syndrome caused by meibomian gland dysfunction are promising. A multisite clinical trial with a larger sample, treatment comparison groups, and randomized controlled trials is currently underway.

    Citation analysis represents one of the best currently available methods for quantifying the impact of articles. Bibliometric studies list the ''best sellers'' in a single field of interest. The purpose of the present study was to identify and analyze the most frequently cited papers in dry eye research that may be of high interest for researchers and clinicians. We reviewed the database of the Institute for Scientific Information to identify articles published from 1900 to September 2016. All dry eye articles published in 59 ophthalmology journals were identified. The top 100 articles were selected for further analysis of authorship, source journal, number of citations, citation rate, geographic origin, article type, and level of evidence. The 100 most-cited articles were published between 1983 and 2011, with most of them in the 2000s. The number of citations per article ranged from 96 to 610, and was greatest for articles published in the 2000s. Each of these articles was published in one of 15 journals.

    Purpose To evaluate dry eye manifestations following photorefractive keratectomy (PRK) and laser in situ keratomileusis (LASIK) and determine the incidence and predictive factors of chronic dry eye using a set of dry eye criteria. Setting Walter Reed Army Medical Center, Washington, DC, USA Methods This is a prospective non-randomized clinical study of 143 active duty U.S. Army personnel aged 29.9±5.2 years with myopia or myopic astigmatism (manifest spherical equivalent −3.83±1.96 diopters) undergoing either PRK or LASIK. Dry eye evaluation was performed pre- and postoperatively. Main outcome measures included dry eye manifestations, incidence, and predictive factors of chronic dry eye. Results Schirmer scores, corneal sensitivity, ocular surface staining, surface regularity index (SRI), and responses to dry eye questionnaire significantly changed over time after PRK. After LASIK, significant changes were observed in tear breakup time, corneal sensitivity, ocular surface staining, and responses to questionnaire. At twelve months postoperatively, 5.0% of PRK and 0.8% of LASIK participants developed chronic dry eye. Regression analysis showed preoperatively lower Schirmer score will significantly influence development of chronic dry eye after PRK whereas preoperatively lower Schirmer score or higher ocular surface staining score will significantly influence the occurrence of chronic dry eye after LASIK. Conclusions Chronic dry eye is uncommon after PRK and LASIK. Ocular surface and tear film characteristics during preoperative examination may help predict chronic dry eye development in PRK and LASIK. PMID:26796443

    The aim of this study was to estimate both the direct and indirect annual cost of managing dry eye disease (DED) in the United States from a societal and a payer's perspective. A decision analytic model was developed to estimate the annual cost for managing a cohort of patients with dry eye with differing severity of symptoms and treatment. The direct costs included ocular lubricants, cyclosporine, punctal plugs, physician visits, and nutritional supplements. The indirect costs were measured as the productivity loss because of absenteeism and presenteeism. The model was populated with data that were obtained from surveys that were completed by dry eye sufferers who were recruited from online databases. Sensitivity analyses were employed to evaluate the impact of changes in parameters on the estimation of costs. All costs were converted to 2008 US dollars. Survey data were collected from 2171 respondents with DED. Our analysis indicated that the average annual cost of managing a patient with dry eye at $783 (variation, $757-$809) from the payers' perspective. When adjusted to the prevalence of DED nationwide, the overall burden of DED for the US healthcare system would be $3.84 billion. From a societal perspective, the average cost of managing DED was estimated to be $11,302 per patient and $55.4 billion to the US society overall. DED poses a substantial economic burden on the payer and on the society. These findings may provide valuable information for health plans or employers regarding budget estimation.

    Full Text Available Peter A Simmons, Cindy Carlisle-Wilcox, Joseph G Vehige Ophthalmology Research and Development, Allergan, Inc., Irvine, CA, USA Background: Dry eye may be caused or exacerbated by deficient lipid secretion. Recently, lipid-containing artificial tears have been developed to alleviate this deficiency. Our study compared the efficacy, safety, and acceptability of lipid-containing eye drops with that of aqueous eye drops.Methods: A non-inferiority, randomized, parallel-group, investigator-masked multicenter trial was conducted. Subjects with signs and symptoms of dry eye were randomized to use one of two lipid-containing artificial tears, or one of two aqueous artificial tears. Subjects instilled assigned drops in each eye at least twice daily for 30 days. The primary efficacy analysis tested non-inferiority of a preservative-free lipid tear formulation (LT UD to a preservative-free aqueous tear formulation (AqT UD for change in Ocular Surface Disease Index (OSDI score from baseline at day 30. Secondary measures included OSDI at day 7, tear break-up time (TBUT, corneal and conjunctival staining, Schirmer’s test, acceptability and usage questionnaires, and safety assessments.Results: A total of 315 subjects were randomized and included in the analyses. Subjects reported instilling a median of three doses of study eye drops per day in all groups. At days 7 and 30, all groups showed statistically significant improvements from baseline in OSDI (P<0.001 and TBUT (P≤0.005. LT UD was non-inferior to AqT UD for mean change from baseline in OSDI score at day 30. No consistent or clinically relevant differences for the other efficacy variables were observed. Acceptability was generally similar across the groups and there was a low incidence of adverse events.Conclusion: In this heterogeneous population of dry eye subjects, there were no clinically significant differences in safety, effectiveness, and acceptability between lipid-containing artificial tears

    Full Text Available Purpose: To compare the efficacies of punctal plug insertion and Botulinum toxin injection in dry eye disease not responding to topical medications. Materials and Methods: A non-controlled randomized clinical trial of two parallel groups of 60 dry eye patients seen in the clinic not responding to topical medications were divided into two groups. One group received punctal plugs and the other group received Botulinum toxin injections to prevent lacrimal tear drainage. Results: Of a total of 36 patients with a mean age of 44.5 years who received punctal plugs, 50% of them experienced improvements in the clinical manifestations of their disease. 12/36 (33.3% developed plug extrusion, and 6/36 (16.7% patients developed conjunctival erosions with irritation that necessitated plug removal within one week of insertion. A total of 24 patients with a mean age of 47.5 years received injections of Botulinum toxin. Of these, 83.3% had improvement in all of the clinical manifestations of dry eye. 4/24 (16.7% had no improvement in the degrees to which they experienced foreign body sensations, 33.3% reported shampoo entering the eye while showering. All of the patients who received Botulinum toxin injections were satisfied with the results of their treatment, whereas only 72.3% of the patients who received punctal plugs were satisfied with their results. Conclusion: Botulinum neurotoxin A injections can be a very good alternative to punctal plugs in improving the clinical manifestations of dry
