    Full Text Available Audience: This modified team-based learning (mTBL exercise is appropriate for junior or senior emergency medicine learners. Introduction: The acute red eye is a common chief complaint in the emergency department. It is essential that the emergency physician be knowledgeable about the differential diagnosis for the acute red eye and be able to distinguish between benign and sinister causes of the acute red eye. Objectives: By the end of this educational session, the learner will: 1 list 10 major causes for an acute red eye; 2 describe historical features that help distinguish between benign and serious causes of the acute red eye; 3 describe physical examination features that help distinguish between benign and serious causes of the acute red eye; and 4 use historical and physical examination features to distinguish between the 10 different causes of the acute red eye. Method: This is an mTBL session.

    Full Text Available Kayo Kure, Ryo Obata, Yuji Inoue, Aya Iriyama, Yasuo YanagiDepartment of Ophthalmology, University of Tokyo School of Medicine, Tokyo, JapanAbstract: Some patients with acute zonal occult outer retinopathy (AZOOR show symptomatic acute visual impairment in one eye only, but electrophysiological abnormalities in both eyes. A 46-year-old female who had noticed paracentral scotoma of her right eye six months previously was referred to our hospital. At initial examination, her best-corrected visual acuity was 0.7 in the right eye and 1.2 in the left. Whereas the full-field rod electroretinogram (ERG was normal in both eyes, the cone response was nonrecordable in the right eye and showed a significant decrease in amplitude in the left eye. The 30 Hz flicker ERG showed similar results. Multifocal ERG was nonrecordable in the right eye and showed a residual response in only the central part of the left. Fourteen months after the first visit, the patient presented complaining of acute visual acuity loss in the left eye. Visual acuity in her left eye had decreased to 0.01. The multifocal ERG was nonrecordable. Although the patient chose oral prednisolone therapy, only limited recovery was observed in the patient. Even if only the ERG shows changes and there are no other symptoms, ophthalmologists should continue observation in view of the possibility of an acute exacerbation.Keywords: acute zonal occult outer retinopathy, electroretinogram, scotoma

    Full Text Available Abstract Background It is a well-known phenomenon that some patients with acute left or right hemisphere stroke show a deviation of the eyes (Prévost's sign and head to one side. Here we investigated whether both right- and left-sided brain lesions may cause this deviation. Moreover, we studied the relationship between this phenomenon and spatial neglect. In contrast to previous studies, we determined not only the discrete presence or absence of eye deviation with the naked eye through clinical inspection, but actually measured the extent of horizontal eye-in-head and head-on-trunk deviation. In further contrast, measurements were performed early after stroke onset (1.5 days on average. Methods Eye-in-head and head-on-trunk positions were measured at the bedside in 33 patients with acute unilateral left or right cerebral stroke consecutively admitted to our stroke unit. Results Each single patient with spatial neglect and right hemisphere lesion showed a marked deviation of the eyes and the head to the ipsilesional, right side. The average spontaneous gaze position in this group was 46° right, while it was close to the saggital body midline (0° in the groups with acute left- or right-sided stroke but no spatial neglect as well as in healthy subjects. Conclusion A marked horizontal eye and head deviation observed ~1.5 days post-stroke is not a symptom associated with acute cerebral lesions per se, nor is a general symptom of right hemisphere lesions, but rather is specific for stroke patients with spatial neglect. The evaluation of the patient's horizontal eye and head position thus could serve as a brief and easy way helping to diagnose spatial neglect, in addition to the traditional paper-and-pencil tests.

    To investigate features of the anterior segment (AS) of the affected eye compared to the fellow eye within the same patient in acute primary angle closure (APAC). Thirty-six patients with unilateral APAC were imaged with AS optical coherence tomography (OCT) before medical or laser treatment for the acute attack. Anterior chamber depth (ACD), iris curvature (IC), iris thickness at 750 μm from the scleral spur (IT750), lens vault (LV), anterior chamber area (ACA), and iris area were estimated by using ImageJ software (version 1.46). Conditional logistic regression analysis was performed to find the associated factors with the prediction of APAC. When compared to fellow eyes, affected eyes showed significantly shallower ACD (1.90 ± 0.24 and 1.55 ± 0.30 mm, respectively; P APAC. Greater LV was the most prominent feature of affected eyes compared to fellow eyes in APAC patients when assessed by AS OCT. This may play a role in the development of acute attack in primary angle closure. Copyright 2014 The Association for Research in Vision and Ophthalmology, Inc.

    Full Text Available AIM: To evaluate changes of proinflammatory cytokines in aqueous humor of patients with acute primary angle-closure (APAC and age-related cataracts. METHODS: Twenty eyes of 20 APAC patients and 15 eyes of 15 age-related cataract patients were included in this cross-sectional study. Aqueous humor samples were collected prospectively. The levels of 20 proinflammatory cytokines were evaluated in the aqueous humor of the APAC and cataract patients using the multiplex bead immunoassay technique. Clinical data were collected for correlation analysis. RESULTS: Seven of the 20 proinflammatory cytokines included in the magnetic bead panel were detectable in both APAC eyes and cataract eyes: interleukin (IL-10, IL-12, IL-15, IL-21, IL-6, chemokine (C-C motif ligand 20, and tumor necrosis factor alpha (TNF-α. IL-27 was only detectable in APAC eyes. Compared with the cataract eyes, the APAC eyes had significantly elevated concentrations of IL-12 (P=0.036, IL-15 (P=0.001, IL-6 (P=0.012, and IL-27 (only detectable in APAC eyes. Age was positively correlated with IL-12 (P=0.022 and IL-6 (P=0.037, and time elapsed between APAC onset and aqueous humor samples collection was positively correlated with IL-15 (P=0.037, IL-27 (P=0.040, and TNF-α (P=0.042. CONCLUSION: Several proinflammatory cytokines including IL-12,IL-15, IL-6 and IL-27, were elevated in the APAC eyes and may be implicated in its pathologic mechanism.

    To measure the anterior and posterior ocular biometric characteristics concurrently and to explore the relationship between iris, ciliary body and choroid in acute primary angle closure eyes (APAC) and fellow eyes. It is a prospective, cross-sectional study. Thirty patients with recent APAC were finally enroled in it. Anterior and posterior uveal parameters were measured simultaneously by anterior segment optical coherence tomography (AS-OCT), swept-source optical coherence tomography (SS-OCT) and ultrasound biomicroscopy (UBM). The parameters were measured including: pupil diameter (PD); iris thickness, curvature (ICURV), area (IAREA); anterior chamber depth (ACD), width (ACW), area (ACA), volume (ACV); lens vault (LV); choroidal thickness and retinal thickness; maximum ciliary body thickness (CBTmax); ciliary body thickness at the point of the scleral spur (CBT0) and 1000 mm away (CBT1000); anterior placement of the ciliary body (APCB); and trabecular-ciliary angle (TCA). Compared with fellow eyes, APAC eyes had narrower anterior biometric parameters and presented with smaller anterior segment parameters (including ACD and ACW); (p APAC eyes had narrower anterior biometric parameters, thinner ciliary body and smaller iris area and curvature. APCB, CBT and choroidal thickness were positively correlated. However, further studies are required before these conclusions are generalised.

    To evaluate diurnal curves of intraocular pressure (IOP) in eyes affected with unilateral acute primary angle closure (APAC) after laser peripheral iridotomy (LPI), and fellow eyes. The medical records of 22 female patients (44 eyes) with unilateral APAC and LPI performed OU were reviewed along with those of 48 normal control subjects (48 eyes). None of the subjects used glaucoma medications after LPI. IOP was measured with a Goldman applanation tonometer during waking hours and in a sitting position every 2 h between 09:00 and 23:00. IOP profiles were compared including the means, peaks, trough IOPs, and IOP fluctuations of the affected, fellow, and normal eyes. The IOPs of the affected eyes were significantly higher than those of normal eyes at every time point measured, including peak and trough IOPs. The diurnal IOPs of fellow eyes were higher than those of normal eyes, though not significantly. There were no significant differences in IOP fluctuation between the affected, fellow, and normal eyes. IOP diurnal curves for APAC affected, fellow, and normal eyes were not statistically different (repeated measures ANOVA, p = 0.865). The mean coefficient of IOP in affected and fellow eyes ranged from 0.486 to 0.604. There were no clinically significant differences among the three groups in terms of IOP diurnal curves, and thus LPI did not have a significant effect on diurnal patterns of IOP. Though the diurnal IOPs of affected eyes after LPI was significantly higher than those of normal eyes, the IOP range was not acute.

    To compare morphometric features between fellow acute primary angle-closure (APAC) eyes and glaucomatous or suspect eyes with narrow angle (NA). Fellow eyes of 30 patients with unilateral APAC and 30 with NA were evaluated by ultrasound biomicroscopy (UBM) under light and dark conditions. UBM parameters such as anterior chamber depth (ACD), angle opening distance at 250 microm/500 microm from the scleral spur (AOD250/AOD500), trabecular ciliary process distance (TCPD) and iris-lens contact distance (ILCD) were measured in the superior (SQ) and inferior (IQ) quadrants. Significant differences between APAC fellow and NA eyes were found in ACD, P<0.001; AOD250 at SQ and IQ, P<0.001; AOD500 at SQ and IQ, P<0.001; TCPD light, P=0.010 and TCPD dark at SQ, P=0.031; and TCPD light at IQ, P=0.010. Significant differences between light and dark examinations of APAC fellow eyes were found in ILCD (P=0.009) at SQ and ILCD at IQ (P=0.006), and of NA eyes in ILCD at SQ (P=0.047) and ILCD at IQ (P<0.001). APAC fellow eyes have a more crowded anterior segment and shallower ACD than NA eyes. ILCD decreases in both groups when the illumination conditions change from light to dark.

    To compare the change in anterior segment morphology after laser peripheral iridotomy (LPI) in acute primary angle closure (APAC) and their fellow eyes. Prospective, fellow eye-matched case series. In this study 42 individuals with unilateral episode of APAC were enrolled and the anterior segment optical coherence tomography (ASOCT) images were obtained in both eyes at baseline and at 6 weeks after LPI. A linear mixed-effects model was used to compare changes in anterior chamber and angle variables with consideration of laterality as the random effect and pupil diameter as the fixed effect. APAC eyes had smaller angle parameters (P = .013 for all), less central anterior chamber depth (cACD) (P APAC and fellow eyes. cACD (P = .003) and ACA (P APAC eyes. However, there was no significant change in cACD (P = .190) and LV (P = .430) in fellow eyes. In both APAC eyes and fellow eyes, iris curvature decreased after LPI (P APAC eyes and their fellow eyes, LPI resulted in significant anterior chamber angle widening and increased anterior chamber area. In APAC eyes, the iris flattened, cACD deepened, and the lens shifted posteriorly after resolution of the attack. However, in fellow eyes, the increase in ACA was mainly owing to decreased iris curvature. Copyright © 2017 Elsevier Inc. All rights reserved.

    The existing literature contains no information regarding inflammatory cytokine expression in unilateral acute primary angle-closure (APAC) affected eyes and fellow eyes with primary angle closure suspect (PACS). To measure levels of various inflammatory cytokines in the aqueous humor (AH) of APAC affected eyes and fellow eyes with a diagnosis of PACS (18 unilateral APAC eyes and 18 fellow eyes with PACS), and determine the underlying correlation between them. The total levels of 12 cytokines including granulocyte colony-stimulating factor (G-CSF), interleukin (IL)-6, IL-8, monocyte chemotactic protein (MCP)-1, MCP-3, macrophage-derived chemokine (MDC), macrophage inflammatory protein (MIP)-1β, and vascular endothelial growth factor (VEGF) etc. were assessed using the multiplex bead immunoassay technique. The level of cytokines in different groups was analyzed by a 2-related-samples nonparametric test. Data on patient demographics, preoperative intraocular pressure (IOP), number of glaucoma medications, as well as several ocular biological parameters were also collected for correlation analysis. The APAC patients had significantly higher levels of G-CSF, IL-6, IL-8, MCP-1, MCP-3, MDC, MIP-1β, and VEGF in the AH samples from unilateral APAC affected eyes than in fellow eyes with PACS (all P APAC. Thus, different cytokine expression in both eyes of the same patient may help us to understand the different pathology in APAC and PACS.

    To determine the frequency and prognostic value of eye deviation detected on the admission computed tomography (CT) of acute ischaemic stroke patients. The clinical and imaging data from the Albumin in Acute Stroke (ALIAS) Trials 1 and 2 were analysed. Two reviewers evaluated all admission CT images for the presence of eye deviation, and Alberta Stroke Program Early CT Score (ASPECTS). The admission National Institutes of Health Stroke Scale (NIHSS) scores and 3-month modified Rankin scale (mRs) scores were ascertained. Disability or death was defined as mRS score >2, at 3-month follow-up. Of 1,223 patients included in the present series, 352 (28.8%) had rightward and 331 (27.1%) had leftward eye deviation on admission CT. Patients with eye deviation on CT had higher admission NIHSS score and larger middle cerebral artery (MCA) territory infarct volume (based on ASPECTS). The presence of eye deviation on CT was associated with higher rates of haemorrhagic transformation at 24 hours (19.8% versus 13.5%, p=0.004), and higher rates of disability or death at 3-month follow-up (53.1% versus 35.7%, pMediation analysis showed that radiological eye deviation relation with higher rate of disability or death is predominantly due to its association with higher admission NIHSS scores, lower ASPECTS, and to a lesser extent patients' older age. The presence of eye deviation on CT examination of acute ischaemic stroke patients is associated with larger anterior circulation stroke volumes, higher risk of 24-hour haemorrhagic transformation, and 3-month disability or death.

    Full Text Available Abstract Background Acute retinal necrosis is a sight-threatening disease caused by the group of herpesviruses. The aim of this paper is to report a case of acute retinal necrosis following ocular trauma in a patient initially treated with vaso-active drugs and corticosteroids for presumed ocular ischemic syndrome. Case presentation A 51-years-old otherwise healthy man, who suffered from sudden visual loss in the left eye following contusion, was commenced on vaso-active drugs and systemic corticosteroids for suspected ocular ischemic syndrome with extensive swelling of the optic disc and macular edema. Subsequently, vision in the initially uninvolved right eye decreased. Polymerase chain reaction of vitreous samples and retinal biopsy confirmed varicella zoster virus. Despite intensive treatment with intravenous antiviral medication, the patient became completely blind in both eyes. Conclusion Initial treatment of acute, unexplained visual decrease with systemic corticosteroids may lead to visual loss in patients with developing acute retinal necrosis. Ocular trauma could have induced and corticosteroid treatment promoted reactivation of a latent viral infection in our patient.

    Acrolein is a potent irritant and a vesicant that was used by the French during WWI as the warfare agent named: "papite". Nowadays, it is produced in large amounts all over the world in the industry for the production of acrylic acid and for agriculture use as herbicide. The aim of this study was to characterize the effects of acute eye exposure to acrolein vapor and to evaluate the efficacy of a topical post-exposure combination treatment with a local anesthetic and a steroid. Rabbit eyes were exposed to three doses of acrolein vapor (low, intermediate and high) and treated topically with either 0.4% benoxinate hydrochloride (localin, for 2 h) or dexamethasone (dexamycin, for 6 days) or a combination of both drugs. Clinical follow-up using slit lamp examinations and histological evaluation was performed 4 weeks post-exposure. Acrolein vapor caused immediate eye closure with excess tearing, corneal erosions and severe inflammation of the anterior chamber. This was followed by corneal neovascularization (NV) starting as early as 1 week post-exposure. The damage to the eyes was long lasting, and at 4 weeks following exposure, significant pathological changes were observed. Immediate post-exposure application of the local anesthetic, localin, prevented the eye closure, and the dexamycin treatment reduced significantly the initial inflammation as well as the extent and incidence of corneal NV. Short-term eye exposure to the irritant acrolein may result in immediate eye closure and long lasting pathologies that could lead to blindness. An anti-inflammatory treatment combined with short-term application of a local anesthetic prevents incapacitation and might minimize significantly the extent of eye injuries.

    Full Text Available Background: Acute primary angle closure (APAC is one of the causes of blindness in Department of Ophthalmology Cipto Mangunkusumo General Hospital. Management of APAC is still controversial. Laser peripheral iridotomy is difficult to be done due to corneal edema as a result of persistent high intraocular pressure (IOP. It is believe that paracentesis will lower IOP immediately. The objective of the study was to assess outcome of paracentesis as the initial management in Malay Indonesian eyes with APAC.Methods: This intervention study was conducted at the Eye Clinic of Cipto Mangunkusumo Hospital and Jakarta Eye Center commencing in January 2005 until December 2007. Malay Indonesian eyes with APAC were included in this study in accordance with the new Asia Pacific consensus. All APAC eyes underwent paracentesis to lower IOP. The presenting and post-paracentesis IOP and peripheral anterior synechiae were noted. The outcome was termed as good when IOP was ≤ 21 mmHg and poor when IOP was > 21 mmHg.Results: A total of 45 APAC eyes were recruited. Thirty-eight of these belonged to women; mean age was 54.6 ± 1.56 years. Meanwhile, average duration of symptoms was 13.15 ± 7.4 days and mean of extent of peripheral anterior synechiae (PAS was 7.7 ± 3.1 hours. There was a strong correlation regarding duration of symptoms to the formation of PAS (r = 0.672; p < 0.001. The mean presenting IOP was 55 ± 13.37 mmHg and mean post-paracentesis IOP was 27 ± 12.78 mmHg. A decrease of 49% in IOP ( p < 0.001 was observed after paracentesis with good outcome in 19 eyes and poor outcome in 26 eyes.Conclusion: Paracentesis as an initial intervention in APAC eyes reduces the IOP immediately, but only as a temporary response.

    To measure levels of various inflammation-related cytokines in the aqueous humor of patients with acute primary angle-closure (APAC) and senile cataract. Aqueous humor samples were prospectively collected from 23 eyes (12 eyes with current APAC and 11 eyes with previous APAC) of 23 APAC patients and 15 eyes of 15 cataract patients. The levels of 15 inflammation-related cytokines in the aqueous humor of APAC and cataract subjects were measured by using the multiplex bead immunoassay technique. Data on patient demographics and preoperative intraocular pressure (IOP) were also collected for correlation analysis. Compared with the group with previous APAC and the cataract group, the group with current APAC showed clear and significantly elevated concentrations of interleukin (IL)-6, IL-8, granulocyte colony-stimulating factor (G-CSF), monocyte chemotactic protein (MCP)-1, MCP-3, and vascular endothelial growth factor (VEGF) (all P APAC and the cataract group had similar levels of cytokines. Intraocular pressure was positively correlated with IL-8 (P = 0.001), G-CSF (P = 0.002), MCP-3 (P APAC. In addition to controlling IOP, anti-inflammatory treatments are necessary for eyes suffering from APAC.

    Glutathione peroxidase activities and malondialdehyde levels were measured in the homogenated anterior segment of rat eyes with endotoxin induced acute anterior uveitis in euthyroid, hyperthyroid and hypothyroid rats. Malondialdehyde concentrations were found to be significantly increased (p 0.05). These results suggest that excess or deficiency of the thyroid hormones cause alterations in the malondialdehyde levels and glutathione peroxidase activities of the rat eyes in endotoxin induced uveitis, and hyperthyroidism may increase the oxidative stress in endotoxin induced acute anterior uveitis.

    Full Text Available Purpose: To compare, clinically and biometrically, affected and fellow acute primary angle-closure (APAC eyes and glaucomatous eyes with narrow angle (NA. Methods: Comparative case series; 30 patients with APAC and 27 glaucomatous patients with NA were evaluated. Keratometry (K, central corneal thickness (CCT, lens thickness (LT, axial length (AL and anterior chamber depth (ACD were measured. Parameters defined as lens posisiton (LP and relative lens position (RLP were calculated. Results: Biometric difference between APAC-affected and fellow eyes was found only in LP (P=0.046. When fellow eyes were compared to glaucomatous eyes with NA, differences were found in ACD (P=0.009, AL (P=0.010, and LT/AL (P=0.005. The comparison between APAC-affected and glaucomatous eyes with NA showed significant differences in almost all biometric parameters, except for LT (P=0.148 and RLP (P=0.374. We found that the logistic regression model (LRM, built with three parameters (K, CCT and LT/AL, higher than 0.334 could be a reasonable instrument to differentiate APAC eyes from glaucomatous eyes with NA. Conclusions: This study showed that APAC-affected and fellow eyes have similar biometric features, and glaucomatous eyes with NA have a less crowded anterior segment. The LRM built showed promising results in distinguishing APAC from glaucomatous eyes with NA.

    The purpose of this study is to compare anterior segment-optical coherence tomography (AS-OCT) parameters in phacomorphic angle closure and acute primary angle closure (APAC) eyes. In this cross-sectional case series, a total of 134 patients with phacomorphic angle closure (28 eyes) or APAC (54 eyes), as well as normal control subjects (52 eyes), were enrolled. Patients underwent AS-OCT imaging and A-scan biometry of both eyes. Anterior chamber depth (ACD), anterior chamber area (ACA), iris thickness (IT), iris curvature, lens vault (LV), anterior vault (AV), and angle parameters including angle opening distance (AOD 500 and AOD750) and trabecular iris space area (TISA500 and TISA750) were measured in qualified images using the Zhongshan Angle Assessment Program and compared among eyes with phacomorphic angle closure, APAC, and normal control subjects. Phacomorphic angle closure and APAC eyes had smaller AOD, ACD, ACA, ACW, AV, and posterior corneal arc length and greater LV than normal controls (P APAC eyes: ACD 1042 μm (OR,12.12; P APAC eyes. In multivariate analysis, ACD, LV, AOD500, and axial length could significantly distinguish the two entities. Ocular biometric parameters can differentiate phacomorphic angle closure from APAC eyes. Shallower ACD and greater LV, axial length, and ACA are the main parameters that distinguish phacomorphic angle closure from APAC.

    Full Text Available Matrix metalloproteinase-3 (MMP-3 is known to mediate neuroinflammatory processes by activating microglia, disrupting blood–central nervous system barriers and supporting neutrophil influx into the brain. In addition, the posterior part of the eye, more specifically the retina, the retinal pigment epithelium (RPE and the blood–retinal barrier, is affected upon neuroinflammation, but a role for MMP-3 during ocular inflammation remains elusive. We investigated whether MMP-3 contributes to acute inflammation in the eye using the endotoxin-induced uveitis (EIU model. Systemic administration of lipopolysaccharide induced an increase in MMP-3 mRNA and protein expression level in the posterior part of the eye. MMP-3 deficiency or knockdown suppressed retinal leukocyte adhesion and leukocyte infiltration into the vitreous cavity in mice subjected to EIU. Moreover, retinal and RPE mRNA levels of intercellular adhesion molecule 1 (Icam1, interleukin 6 (Il6, cytokine-inducible nitrogen oxide synthase (Nos2 and tumor necrosis factor α (Tnfα, which are key molecules involved in EIU, were clearly reduced in MMP-3 deficient mice. In addition, loss of MMP-3 repressed the upregulation of the chemokines monocyte chemoattractant protein (MCP-1 and (C-X-C motif ligand 1 (CXCL1. These findings suggest a contribution of MMP-3 during EIU, and its potential use as a therapeutic drug target in reducing ocular inflammation.

    To determine retinal nerve fiber layer thickness (RNFLT) using Spectral optical coherence tomography/scanning laser ophthalmoscope (Spectral OCT/SLO) in Asian Indian eyes after single, unilateral attack of acute primary angle closure (APAC). Thirty-two patients with unilateral attack of APAC with normal optic disc and normal visual field, unaffected fellow eyes, and 35 age-matched normal control eyes were enrolled for the study. Six weeks after the remission of acute attack, peripapillary average, quadrant, and clock-hour RNFLT were compared between 3 groups using Spectral OCT/SLO. APAC patients had mean IOP of 51.3±13.3 mm Hg (range, 40-74) at the time of presentation with acute attack in the affected eye and 14.9±2.9 mm Hg at 6 weeks after resolution of APAC. Duration of symptoms of acute attack was 35.9±23.8 hours. Significant differences were found between RNFLT in APAC and fellow eyes for most the parameters except for 1, 4, 6, and 7-o'clock-hour sector. Most of the RNFLT parameters showed statistically significant difference between APAC and normal control eyes except for temporal quadrant, 6, 7-o'clock-hour sectors. Statistically significant differences were found between RNFLT in unaffected fellow and normal control eyes for most of the parameters except for 6, 7, 11 o'clock-hour sectors. RNFLT was found to be significantly thinner in APAC and unaffected fellow eyes when compared with normal age-matched controls. Hence, patients with APAC should be monitored carefully to determine its long-term effects on optic disc, RNFLT, and visual fields. Longitudinal studies can determine whether the RNFLT measurements remained stable or showed progression in these patients.

    Management of diabetic retinopathy should follow more strict and aggressive rules in patients at risk for severe acute renal impairment. Such patients should be identified and possibly prophylactically laser treated to avoid the severe consequences demonstrated in this case report. A 34-year-old type 2 diabetes patient with a stabilized diabetic retinopathy developed acute and severe retinal decompensation within weeks after acute renal failure complicated his chronic stable renal impairment. Fluorescein angiographic and optical coherence tomographic illustrations of the rapid evolution of the retinal condition are presented. The patient had previously been treated with panretinal photocoagulation in his left eye. After 8 years of regular 6-monthly checked stability, he developed rapid-onset proliferative diabetic retinopathy and macular edema in his right eye within 3 months of his last ocular check-up. Fluorescein angiography showed neovessels and major ischemic areas. Emergency panretinal photocoagulation and a sub-Tenon's injection were necessary to achieve control of the situation with regression of neovessels and complete regression of macular edema. This case shows that it is imperative for nephrologists to be well informed about a patient's ocular situation in order to give timely information to the ophthalmologist who can intervene to protect the retina in case of renal failure. On the other hand, the ophthalmologist should be familiar with the renal function of his patient with renal impairment so that he can decide to perform prophylactic retinal panphotocoagulation that should be imperatively considered even without strict indications in patients with renal impairment at risk for further deterioration of renal function, in order to prevent such explosive ischemic and proliferative retinopathy putting vision at risk.

Treatment strategies in both centers were effective in aborting an APAC attack. The development of raised IOP appears to be associated with a longer period of attack suggesting that greater urgency in aborting APAC attacks may entail better long term outcomes.

    The purpose was to investigate peripapillary retinal vessel density in resolved acute primary angle closure (APAC) eyes. This was a prospective, cross-sectional observational study. Thirty-four eyes of 34 patients with unilateral APAC were included, together with the fellow eyes with primary angle closure suspect (PACS) as controls. Peripapillary retinal vessel density was measured using optical coherence tomography (OCT) angiography. Peripapillary retinal vessel density was compared in both eyes and the potential relationship with visual field (VF) test results was evaluated. After an acute attack, the peripapillary retinal vessel density was lower in the APAC than in the PACS eyes (79.3 ± 8.2 versus 85.6 ± 4.9, respectively; P = 0.001). The VF mean deviation (MD) (-7.7 ± 6.7 versus -3.3 ± 1.8 dB, P = 0.002), and the pattern standard deviation (PSD) (4.6 ± 3.3 versus 2.4 ± 0.9 dB, P = 0.001) were worse for the APAC than the PACS eyes, but both had similar thicknesses of the retinal nerve fiber layer (RNFL) (111.8 ± 9.6 versus 114.1 ± 29.1 μm, P = 0.880) and ganglion cell complex (GCC) (94.7 ± 7.5 versus 91.8 ± 9.3 μm, P = 0.328). The peripapillary retinal vessel density was significantly correlated with the VF MD (vessel density: r = 0.455, P = 0.008) and PSD (vessel density: r = -0.592, P APAC eyes. Even when IOP was normalized after the acute attack, the APAC eyes had a lower peripapillary retinal vessel density, which was correlated with the VF values. OCT angiography is a reliable method for detecting vascular changes in glaucomatous eyes that show no thinning of the RNFL and GCC.

    Full Text Available Introduction. Sleep disturbances are commonly found in patients in the postoperative period. Sleep disturbances may give rise to several complications including cardiopulmonary instability, transient cognitive dysfunction and prolonged convalescence. Many factors including host inflammatory responses are believed to cause postoperative sleep disturbances, as inflammatory responses can alter sleep architecture through cytokine-brain interactions. Our aim was to investigate alteration of sleep architecture during acute infection and its relationships to inflammation and clinical symptoms.Materials & Methods. In this observational study, we included patients with acute uncomplicated diverticulitis as a model to investigate the isolated effects of inflammatory responses on sleep. Eleven patients completed the study. Patients were admitted and treated with antibiotics for two nights, during which study endpoints were measured by polysomnography recordings, self-reported discomfort scores and blood samples of cytokines. One month later, the patients, who now were in complete remission, were readmitted and the endpoints were re-measured (the baseline values.Results. Total sleep time was reduced 4% and 7% the first (p = 0.006 and second (p = 0.014 nights of diverticulitis, compared to baseline, respectively. The rapid eye movement sleep was reduced 33% the first night (p = 0.016, compared to baseline. Moreover, plasma IL-6 levels were correlated to non-rapid eye movement sleep, rapid eye movement sleep and fatigue.Conclusion. Total sleep time and rapid eye movement sleep were reduced during nights with active diverticulitis and correlated with markers of inflammation.

    To investigate the frequency of appositional angle closure and related anatomic characteristics in fellow eyes of Chinese subjects with acute primary angle closure (APAC) after laser peripheral iridotomy (LPI). Cross-sectional study. Consecutive subjects with APAC presenting from April 2006 to September 2006 at the Glaucoma Service of Peking University Eye Center, Peking University Third Hospital. Under dark conditions, fellow eyes were divided into 2 groups based on the detection of appositional angle closure by ultrasound biomicroscopy (UBM). For all subjects, UBM parameters were measured to evaluate the different anatomic features between the 2 groups. Darkroom provocative tests (DRPTs) and gonioscopy were performed to investigate the relationship between angle closure and intraocular pressure. Central anterior chamber depth (ACD); angle opening distance(500) (AOD(500)); angle recess area(750) (ARA(750)); trabecular-iris angle (T-I angle); trabecular-ciliary process distance (TCPD); peripheral iris thickness (IT(1)); iris-zonule distance (IZD); and the position of the iris insertion. Thirty-four post-LPI fellow eyes of 34 patients with APAC (8 men, 26 women; mean +/- standard deviation age 66.3+/-7.2 years, range 54-83) were included. Peripheral anterior synechiae (PAS) were not observed in any subject. Appositional angle closure was observed in at least 1 quadrant in 13 (38.2%) of the 34 patients. Compared with eyes without appositional closure, eyes with appositional closure showed significantly lower AOD(500), ARA(750), and T-I angle in 4 quadrants; shorter TCPD in the inferior and temporal quadrants; and thicker IT(1) in the superior and nasal quadrants (PAPAC showed appositional angle closure after LPI. The anatomic findings indicate a narrower angle, a more anterior position of the ciliary body, and a thicker peripheral iris in fellow eyes of APAC after LPI may be associated with an increased risk for progressive angle closure.

    Conjugate eye deviation (CED) and horizontal skew deviation are often seen in patients with intracerebral hemorrhage (ICH), but its prognostic significance is unclear. In this study, the association between brain scan assessed eye position and hospital mortality in patients with supratentorial ICH was tested. A retrospective analysis was performed in 316 patients with supratentorial ICH. Eye position was measured on first brain computed tomography or magnetic resonance imaging. Patients with CED, horizontal skew deviation or no deviation were distinguished. The association between eye position and hospital mortality was assessed using logistic regression analysis. Conjugate eye deviation was present in 96 (30.4%), skew deviation in 44 (13.9%) and no deviation in 176 (55.7%) patients. In patients with CED, 81.3% had an eye position to the ipsilateral side of the hemorrhage. In univariable regression analysis, skew deviation was associated with mortality (odds ratio 3.10, 95% confidence interval 1.57-6.11; P = 0.001). In multivariable regression analysis, adjusting for age, ICH volume, intraventricular extension and Glasgow Coma Scale, eye position was not independently associated with mortality. Horizontal skew eyes were found to be an unfavorable prognostic factor. However, this was not independent of other important predictors of ICH mortality and is most probably explained by its association with worse initial clinical presentation. © 2016 EAN.

    A 1-year-old, female spayed, domestic shorthair cat presented for blepharospasm of the right eye. Slit-lamp biomicroscopic examination showed focal corneal ulceration and presumptive keratomalacia of the right eye. Examination of the left eye was normal apart from a focal endothelial opacity. Within the first 24 h of medical management, the right eye developed marked corneal edema and globular anterior protrusion of the corneal surface consistent with feline acute corneal hydrops (FACH). Surgical management consisted of a bridge conjunctival graft, nictitating membrane flap, and temporary tarsorrhaphy. Resolution of corneal edema and pain occurred in the right eye within 24 days. Spectral domain optical coherence tomography (SD-OCT) of the anterior segment was performed in both eyes. Conjunctival tissue from the bridge graft precluded examination of deeper corneal structures in the right eye. The left eye displayed a focal separation of the corneal endothelium and Descemet's membrane from the overlying stroma. These SD-OCT findings are similar to the analogous syndrome found in humans and represent a potential etiology for FACH of the right eye in the case presented here. Unfortunately, the cat was lost to follow-up and the progression of this lesion to FACH in the left eye could not be determined. © 2017 American College of Veterinary Ophthalmologists.

    We evaluated choroidal thickness in the fellow eyes of patients with acute primary angle-closure (APAC) and compared findings to those of normal controls. The study group comprised 44 fellow eyes defined as primary angle-closure suspect (PACS) of 44 subjects who had experienced APAC and 43 eyes of 43 healthy volunteers. Using enhanced depth imaging optical coherence tomography (EDI-OCT), the peripapillary and macular choroidal thickness of the PACS eyes and the control eyes were measured and compared at each location or segment. Pearson correlation analysis and a multivariable regression model were used to evaluate the relationships between choroidal thickness and related factors. At all the macular locations, the choroidal thickness was thickest at the subfovea. The PACS eyes had a thicker choroid than the control eyes at all macular locations (all P 0.05). PACS eyes that had a fellow eye experience of APAC had a thicker macular choroid than the control eyes. The potential role of a thicker choroid as a risk factor for APAC must be investigated further.

    Analyzing a personal series of children with acute optic neuritis (AON), we studied A retrospective study of 28 eyes in 20 patients (mean age: 10;7 years), examined between 1982 and 1997, with a follow-up ranging from 6 months to 15 years (mean: 5;5 years). We recorded etiologic factors, clinical features (ocular and extra ocular), biological results, and neuroimaging findings. Initial involvement was uni- or bilateral with poor visual acuity (under 20/200 in 22 eyes of 28). Intracerebral inflammation was present in 9 of 13 cases where MRI was performed. We found a cause in only 7 cases (5 viral diseases and 2 recent vaccinations against hepatitis B). Visual recovery was good (over 20/25 in 20 eyes of 28) whatever the treatment, but AON recurred in 5 children. Four children later developed multiple sclerosis. The cause of AON is rarely found. After eliminating an infection, we retained viral disease, complication of a recent vaccination against hepatitis B, and neurological diseases. MRI was the imaging study of choice. Development of multiple sclerosis occurred in 4 cases of 20, the same frequency as in the literature. The risk of later development of multiple sclerosis was 20%. Progression of AON was often excellent. Nevertheless, corticotherapy was added, in form of intravenous boluses followed by decreasing oral therapy for one month.

    Mini-scleral lenses are an increasingly popular contact lens modality; however, there are relatively few reports regarding the unique aspects of their fitting and potential complications. We report a complication of mini-scleral lens wear in a 44-year-old female patient using the lenses for keratoconus. Her mini-scleral contact lenses were non-fenestrated and fitted to vault over the cornea and seal at the periphery. The patient presented with an acute red eye (non-ulcerative keratitis), characterised by unilateral severe conjunctival and limbal hyperaemia, corneal infiltration and pain. Refitting the lens to increase the corneal vault clearance did not prevent recurrence of the keratitis, some five months later. Successful prevention of further episodes of the acute red eye was achieved through improved patient compliance with lens cleaning, disinfection and lens case procedures. Lens hygiene may be particularly important for mini-scleral lenses with a sealed fitting. © 2013 The Authors. Clinical and Experimental Optometry © 2013 Optometrists Association Australia.

    Full Text Available The relationship between aquaporin (AQP 5 and mucin (MUC 5AC in the conjunctiva was investigated in response to acute dry eye (DE stress. A mixed-mechanism rabbit DE model, in which the main lacrimal gland, Harderian gland, and nictitating membrane were resected, was further explored in this study. Conjunctival impression cytology specimens were harvested before excision (BE and up to 3 months after excision (AE in 8 (16 eyes male New Zealand White rabbits, and immunoblotting was employed to assess the expression of AQP5 and MUC5AC. It was observed that AQP5 and MUC5AC showed a positive, synchronous expression pattern with progressive upregulation at protein level up to 2 months AE. At 3 months, the expression of both proteins decreased, but was still higher than that of BE. Such a synchronous relationship was further observed in mouse conjunctiva epithelium primary cells under hyperosmotic condition. Moreover, the co-immunoprecipitation of AQP5 and MUC5AC suggested a possible physical interaction between the two molecules. Our data indicates that conjunctival AQP5 and MUC5AC act synchronously in response to acute DE stress.

    To measure aqueous humor levels of TGF-β2 and TNF-α in Indonesian eyes with acute primary angle closure (APAC) and to investigate their relationship to response to treatment. A prospective observational study. On presentation, aqueous humor samples were taken from APAC eyes by paracentesis. All APAC eyes then underwent laser peripheral iridotomy (LPI). Two weeks following LPI, trabeculectomy was performed if the intraocular pressure (IOP) was still high. Alternatively, phacoemulsification was performed in cases of normal IOP. Aqueous humor samples were taken again at the time of both surgical procedures. Age-matched cataract patients were included as a control group. Cytokine samples were measured by enzyme-linked immunosorbent assay (ELISA). Forty-three Indonesian APAC subjects were recruited in this study. The mean presenting IOP was 56.4 ± 0.52 mmHg and 53% underwent trabeculectomy. Comparison of the APAC eyes to the control group showed there was a significant difference in the mean levels of TGF-β2 (2007.7 ± 827.2 pg/mL vs 466.1 ± 219.3 pg/mL, p < 0.001) and TNF-α (0.714 ± 0.33 pg/mL vs 0.228 ± 0.16 pg/mL, p < 0.001). There was no significant difference in the presented TGF-β2 and TNF-α levels between the trabeculectomy and phacoemulsification groups (p:0.391 and p:0.494). Between presentation and surgery in the trabeculectomy subgroup, both cytokine levels appeared to be significantly different (p < 0.035 and p < 0.038). This study showed the aqueous humor levels of TGF-β2 and TNF-α appeared high at presentation but decreased subsequently, with no difference detected between groups with persistently high IOP and those with normalized IOP.

    To estimate and compare changes in the Bruch's membrane opening-minimum rim width (BMO-MRW) and area in normal, ocular hypertensive and glaucoma eyes following acute elevations in intraocular pressure (IOP). The optic nerve heads (ONHs) of 104 subjects (31 normals, 20 ocular hypertension (OHT) and 53 with primary glaucoma) were imaged using Spectral-domain optical coherence tomography (OCT; Spectralis, Heidelberg Engineering, Germany). IOP was raised twice by applying a force (0.64 n then 0.9 n) to the anterior sclera using an ophthalmo-dynamometer. After each IOP increment, IOP was held constant, measured with a Tonopen (AVIA applanation tonometer, Reichert, Depew, New York, USA), and ONH was rescanned with OCT. In each OCT volume, BMO-MRW and area were calculated and at each IOP increment. The baseline MRW was significantly smaller in glaucoma subjects (174.3±54.3 µm) compared with normal (287.4±42.2 µm, pglaucoma subjects was significantly thinner at the first and second IOP elevations than that at baseline (both p0.05). Acute IOP elevation leads to compression of the nerve fibre layers of neuroretinal rim in glaucoma subjects only without changing ONH size. This suggests that the neural and connective tissues at ONH level in glaucoma subjects are more susceptible to acute IOP episodes than OHT or normal controls. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    To explore the mechanism of the eye-acupuncture for treatment of acute cerebral ischemia-reperfusion injury. Thirty-two healthy SD rats were randomly divided into a normal group, a sham operation group, a model group and an eye-acupuncture group, 8 rats in each group. The rat model of cerebral ischemia-reperfusion was established with thread occlusion method in the model group and the eye-acupuncture group. The eye-acupuncture group was treated by eye-acupuncture at "liver region", "upper energizer area", "lower energizer area" and "kidney region" for 20 min immediately after reperfusion and at 30 min before sampling. No treatment was done in the normal group and the sham operation group, and no thread occlusion was performed in the sham operation group. The Neurologic impairment was scored and the methods of immunohistochemistry staining, western-blotting and real-time fluorescent quantitation polymerase chain reaction (RQ-PCR) were taken to detect the expression of the aquaporin protein 4 (AQP4) and its mRNA in cerebral cortex after reperfusion for 3 hours. The neurologic impairment score of 1.50 +/- 0.54 in the eye-acupuncture group was significant lower than 2.63 +/- 0.92 in the model group (P eye-acupuncture group, with statistical significance compared to 150.88 +/- 15.82 and 0.94 +/- 0.04 in the model group (all P eye-acupuncture group and the normal group (both P eye-acupuncture therapy can relieve the cerebral ischemia-reperfusion injury and the protective mechanism is related to the downregulation of the cerebral AQP4 expression.

    Full Text Available The common use of Pouteria mammosa (L. Cronquist, “Mamey or Zapote,” in food and ethnobotanic medicine shows its low or absent toxicity as fruit extracts prepared from seeds. However, it is essential to conduct security trials to scientifically support their use in drug therapy. This study evaluated the aqueous and hydroalcoholic extract (25% Acute Oral Toxicity, obtained from the seeds of P. mammosa, in Sprague Dawley rats and dermal and eye irritability in New Zealand rabbits. The 404 and 405 acute dermal and eye irritation/corrosion guidelines were used, as well as the 423 Acute Oral Toxicity guideline, Acute Toxic Class Method of the Organization for Economic Cooperation and Development (OECD. The aqueous extract was located in the following category: not classified as toxic (CTA 5, while hydroalcoholic extract at 25% was classified as dangerous (CTA 4. Both extracts can be used without side reaction that irritates the skin which permitted classification as potentially not irritant. P. mammosa in the two extracts caused mild and reversible eye irritation, and it was classified as slightly irritating.

    To compare the features of postiridotomy ultrasound biomicroscopy (UBM) in Chinese patients with acute primary angle-closure (aPAC) and with chronic primary angle-closure (cPAC) glaucoma. Consecutive cases were classified into acute and chronic groups. The acute group included 77 patients with unilateral aPAC. The chronic group included 57 patients with unilateral advanced cPAC glaucoma. In both the groups, the patients' fellow eye underwent a laser iridotomy and was studied. The main outcome measures included qualitative UBM parameters such as a plateau iris, anterior iris insertion, and an anteriorly rotated ciliary process and quantitative UBM parameters such as central anterior chamber depth (ACD), basal iris thickness (IT500), and scleral ciliary process angle (SCPA). For the qualitative parameters, more eyes in the chronic group had a plateau iris (P=0.046), an anterior iris insertion (P=0.222), and an anteriorly rotated ciliary process (P=0.090) than those in the acute group. For the quantitative parameters, the eyes in the chronic group had a deeper ACD (PaPAC may have a shallower ACD. For Chinese patients, a nonpupillary block component may play a more important role in asymptomatic cPAC than in aPAC.

    Stimulation of cell regeneration in the brain and eye retina in various degenerative processes is a pressing problem in neurobiology. A promising approach is transplantation of somatic cells reprogrammed towards neural lineage. We studied the effect of transplantation of retinal pigment epithelial cells from adult human eye transdifferentiated in culture on degenerative processes in the brain of rats subjected to acute hypoxia. Immunohistochemical and molecular genetic analysis suggests that retinal pigment epithelial cells transdifferentiate in vitro and express markers of low-differentiated neural cells. The cells transplanted into rat brain survive for at least 20 days. During this period, they stimulate compensatory and reparative processes that protected cortical neurons in the recipients from hypoxia-induced degeneration.

The purpose of this study was to explore whether or not synchronous neural activity changes were measured with the regional homogeneity (ReHo method in acute EP patients.Methods: A total of 20 patients (15 males and 5 females with EP and 20 healthy controls (HCs consisting of 15 and 5 age-, sex-, and education-matched males and females, respectively, underwent resting-state functional magnetic resonance imaging. The ReHo method was applied to assess synchronous neural activity changes.Results: Compared with HCs, acute EP patients had significantly lower ReHo values in the left precentral/postcentral gyrus (Brodmann area [BA]3/4, right precentral/postcentral gyrus (BA3/4, and left middle frontal gyrus (BA6. In contrast, higher ReHo values in acute EP patients were observed in the left superior frontal gyrus (BA11, right inferior parietal lobule (BA39/40, and left precuneus (BA7. However, no relationship was found between the mean ReHo signal values of the different areas and clinical manifestations, which included both the duration and degree of pain in EP patients.Conclusion: Our study highlighted that acute EP patients showed altered synchronous neural activities in many brain regions, including somatosensory regions.

    Alcohol is one of the most consumed psychoactive substances in the world, and the negative impact related to alcohol use has become a worldwide public health issue. Alcohol is able to affect diffusely several areas of the Central Nervous System, which could impair visual functions, including eye movements, and cognitive processes. The objective of the present study was to investigate the effects of moderate alcohol intake in eyes movements, as an indicator of cognitive processing underlying the visual search in a the Maze task. We investigated the concentration of 0.08% blood alcohol concentration (BAC), using an intra-subject, double-blind, and placebo-controlled experimental design with a sample size of 20 young adults (11 men and nine women). All volunteers participated in both conditions, i.e., alcohol (0.08%) and placebo (0.00%), in a counterbalanced order. We use the Tobii TX300 eye tracker to evaluate eye movements during completion of Visual Maze Test. The results showed significant differences in the following eye movement patterns: the first fixation latency, number and duration of fixations (mean and total), the number and duration of saccades (mean and total), and the total execution time in the test. In addition, we investigate the areas of interest (AOI), decision points in which the participant must decide which course to follow. We verified that the participants in the alcohol condition had a significantly greater number of fixations in both AOI, in comparison to the placebo condition. Overall, our findings confirm that moderate doses of alcohol can change the eye movements of young adults. These alterations may evidence the influence of alcohol in cognitive processes, such as flexibility, attention, and planning, which are required during resolution of Maze Task.

    Visual impairment, specifically eye movement disorders and vestibular dysfunction may have a negative influence on the functional recovery in post-stroke patients. This type of sensory dysfunction may further be associated with poor functional outcome in patients' post-stroke. In phase 1, a cross-sectional survey ( n  = 100) will be conducted to determine the prevalence of eye movement disorders and vestibular dysfunction in patients who sustained a stroke. A cross-sectional clinical trial ( n  = 60) will be conducted during phase 2 of the study to determine the effect of the combination of vestibular rehabilitation therapy (VRT) and visual scanning exercises (VSE) (experimental group) integrated with task-specific activities compared with the effect of task-specific activities as an intervention (control group) on patients who present with eye movement impairment and central vestibular dysfunction post-stroke. An audiologist will assess (a) visual acuity (static and dynamic), (b) nystagmus, (c) saccadic eye movements, (d) smooth pursuit eye movements, (e) vestibulo-ocular reflex, and (f) saccular, utricular, and vestibular nerve function. An independent physiotherapist will assess (1) cognitive function, (2) residual oculomotor visual performance, (3) visual-perceptual system, (4) functional balance, (5) gait, (6) functional ability, (7) presence of anxiety and/or depression, and (8) level of participation in physical activity. Ethics approval has been obtained from the Ethics Committee of the Faculty of Health Sciences at the University of Pretoria (UP) (374/2015). The study will be submitted as fulfillment for the PhD degree at UP. Dissemination will include submission to peer-reviewed professional journals and presentation at congresses. Training of rehabilitation team members on the integration of VSE and VRT into task-specific activities in rehabilitation will be done if the outcome of the experimental group's functional performance is clinically and

    The Visual Impairment and Intracranial Pressure (VIIP) syndrome affects 60% of astronauts returning from long-duration missions and is characterized by structural and functional changes of the eye (3). Upon entry into weightlessness, approximately two liters of fluid translocates from the lower body to the thorax and cephalad regions, potentially contributing to elevated intracranial and intraocular pressures. The choroid is the vasculature that supplies blood flow to the posterior part of the retina and has limited autoregulation. As a consequence these vessels may engorge during a cephalad fluid shift, contributing to structural changes in the retina. The purpose of this experiment was to quantify changes in choroid thickness during a fluid shift. In order to fulfill this objective, it was also necessary to improve the measurement technique for assessing choroid thickness.

  2. [The electroretinogram parameters and the state of the cornea in the rabbit following acute exposure of the eye to UV-radiation of different intensities].

    Science.gov (United States)

    Belousov, V V; Gramenitskiĭ, A E

    1991-01-01

    The purpose of this study was to investigate wave amplitudes and latencies of electroretinograms (ERG) and to examine the eye cornea of rabbits a month after their eye UV-B-irradiation with a biologically effective dose of 1.3 kJ/m2 at three intensities of 1.62, 0.567 or 0.157 W/m2. It was demonstrated that ERG a- and b-waves decreased significantly 7-20 days after irradiation while latencies remained unchanged. It was also found that during this time period ERG wave amplitudes were dependent on the intensity: at higher intensities amplitudes of both waves diminished to a greater extent. After irradiation with a peak intensity photokeratoconjunctivitis was more severe and prolonged; however, the effect of irradiation with two other intensities was very similar. In view of the fact that the highest intensity of UV-B-radiation was comparable with that beyond the Earth's atmosphere while the lowest intensity was close to that near the Earth's surface, the above findings can be used to solve space biology problems and to assess potential effects of the ozone layer destruction on the eye.

  20. Comparison of the acute ocular manifestations of Stevens-Johnson syndrome and toxic epidermal necrolysis in Chinese eyes: a 15-year retrospective study.

    2017-05-12

    Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare but life-threatening conditions that initially affect the skin and mucous membranes. The aim of this study was to compare the acute ocular manifestations between SJS and TEN. The initial presenting ophthalmic records of patients with either SJS ( = 30% involvement), who were treated at one tertiary burn center in Hong Kong between 1999 and 2014, were retrospectively analyzed and compared. A total of 20 SJS and 12 TEN cases were included. All were drug-induced. The patient demographics and treatment received were comparable. Overall, 40% of SJS and 75% of TEN patients had acute ocular surface inflammation. When comparing the two groups, there was a significant difference in the number of cases with mild involvement (5% in SJS, 42% in TEN, p = 0.01), while no statistically significant differences were found (p > 0.05) comparing between the moderate (15% in SJS, 0% in TEN) and severe groups (20% in SJS, 33% in TEN). Ocular surface inflammation was common during the acute phase in both SJS and TEN. TEN had a significantly higher number of cases with mild ocular involvement when compared with SJS, but no significant difference between the number of moderate and severe cases between the two groups.

    Full Text Available PURPOSE: To compare morphometric features between fellow acute primary angle-closure (APAC eyes and glaucomatous or suspect eyes with narrow angle (NA. METHODS: Fellow eyes of 30 patients with unilateral APAC and 30 with NA were evaluated by ultrasound biomicroscopy (UBM under light and dark conditions. UBM parameters such as anterior chamber depth (ACD, angle opening distance at 250 µm/500 µm from the scleral spur (AOD250/AOD500, trabecular ciliary process distance (TCPD and iris-lens contact distance (ILCD were measured in the superior (SQ and inferior (IQ quadrants. RESULTS: Significant differences between APAC fellow and NA eyes were found in ACD, POBJETIVO: Comparar características morfométricas entre olhos contralaterais com fechamento angular primário agudo (FAPA e olhos glaucomatosos ou suspeitos com ângulo estreito (AE. MÉTODOS: Olhos contralaterais de 30 pacientes com FAPA unilateral e olhos de 30 pacientes com AE foram avaliados através da biomicroscopia ultra-sônica (BUS no claro e escuro. Parâmetros da BUS como a profundidade central de câmara anterior (PCA, distância da abertura angular a 250 µm/500 µm do esporão escleral (AOD250/AOD500, distância entre o processo ciliar e o trabeculado (TCPD e distância do contato iris-cristalino (ILCD foram medidos nos quadrantes superior (QS e inferior (QI. RESULTADOS: Diferenças significativas entre olhos contralaterais de FAPA e olhos com AE foram encontradas na PCA, p<0,001; AOD250 no QS e QI, p<0,001; AOD500 no QS e QI, p<0,001; TCPD no claro, p=0,010 e TCPD no escuro no QS, p=0,031; e TCPD no claro no QI, p=0,010.

    Full Text Available Pictorial images are icons as well as eye-cons: they provide distillations of objects or ideas into simpler shapes. They create the impression of representing that which cannot be presented. Even at the level of the photograph, the links between icon and object are tenuous. The dimensions of depth and motion are missing from icons, and these alone introduce all manner of potential ambiguities. The history of art can be considered as exploring the missing link between icon and object. Eye-cons can also be illusions—tricks of vision so that what is seen does not necessarily correspond to what is physically presented. Pictorial images can be spatialised or stylised; spatialised images generally share some of the projective characteristics of the object represented. Written words are also icons, but they do not resemble the objects they represent—they are stylised or conventional. Icons as stylised words and spatialised images were set in delightful opposition by René Magritte in a series of pipe paintings, and this theme is here alluded to. Most of visual science is now concerned with icons—two-dimensional displays on computer monitors. Is vision now the science of eye-cons?

    Full Text Available Icons are eye-cons: they provide a distillation of a complex object or idea into a simple pictorial shape. They create the impression of representing that which cannot be presented. Even at the level of the photograph, the links between icon and object are tenuous. The dimension of distance or depth is missing from the icon, and this alone introduces all manner of potential ambiguities. The history of art can be considered as an exploration of the missing link between icon and object. Eye-cons are more honest—they are tricks of vision so that what is seen does not necessarily correspond to what is presented. They are visual allusions rather than visual illusions, although they can display illusory effects. At its broadest, icon can be equated with image. The concept of image has thrived on its vagueness, and so attempts have been made to refine it. An icon corresponds to an optical image: it shares some of the projective characteristics of the object represented. Written words are also icons but they do not resemble the objects they represent—they are stylised or conventional rather than spatialised and projective. Words and images were set in delightful opposition by René Magritte (1898-1967 in a series of pipe paintings, and he also played on the theme of the arbitrariness of the verbal labels assigned to objects. What is surprising is that Magritte did not apply his painterly skills to transforming the word shapes he used. A similar reluctance to transform the typefaces pervades visual poetry. My interests are in the visual rather than the poetic dimension, and I will present a range of my own eye contricks which play with letter and word shapes in a variety of ways.

  15. The mouse small eye mutant, Del(2)Sey3H, which deletes the putative tumor suppressor region of the radiation-induced acute myeloid leukemia is susceptible to radiation

    International Nuclear Information System (INIS)

    Nitta, Yumiko; Yoshida, Kazuko; Tanaka, Kimio; Peters, Jo; Cattanach, Bruce M.

    2003-01-01

    Radiation-induced murine acute myeloid leukemia (AML) is characterized by the chromosome 2 deletions. Standing on the hypothesis that an AML suppressor gene would locate on the chromosome 2, a deletion-wide screen was performed on radiation-induced AMLs by the fluorescence in situ hybridization (FISH) method. The hemizugous deletion of the D2Mit15, a marker DNA at the 49.0cM region from the centromere, associated with the AMLs in 97 out of the 105 cases (92.4%). As the deletion region was close to the region of human WAGR syndrome (MIM194072), the mouse small eye mutants could be the animal model for radiation-induced AMLs. The mutant, Del(2)Sey3H (Sey3H) was found to delete around the 49.0cM region by the allelic loss mapping. The Sey3H showed high susceptibility to radiation to develop tumors including the myeloid leukemia with shorter latency. These finding support the existence of a putative tumor suppressor gene responsible for the radiation-leukemogenesis near the D2Mit15 region. (author)

  16. Disconjugate eye movements.

    Science.gov (United States)

    Straumann, Dominik

    2007-01-01

    To foveate targets in different depths, the movements of the two eyes must be disconjugate. Fine measurements of eye rotations about the three principal axes have demonstrated that disconjugate eye movements may appear not only in the horizontal, but also in the vertical and torsional directions. In the presence of visual targets, disconjugate eye movements are driven by the vergence system, but they may also appear during vestibular stimulation. Disconjugate eye movements are highly adaptable by visual disparities, but under normal condition the effects of adaptation only persist when one eye is covered. Finally, disorders of the brainstem and cerebellum may lead to abnormal disconjugate eye movements that are often specific for the topography of the lesion. This chapter reviews the literature on the phenomenology of disconjugate eye movements over the last 15 years.

  18. Is a submissive posture adaptive when being evaluated negatively? Effects on cortisol reactivity.

    Science.gov (United States)

    Turan, Bulent

    2015-01-01

    Subordinate status and submissiveness are stressful and are often associated with ill-health. However, when there is a physical or social threat posed by more powerful others, showing submissiveness may be a good strategy to avoid or terminate conflict. One way to show submissiveness is to assume a subordinate body posture, which may also help regulate one's own stress responses by making one feel safer, and by diverting attention away from one's negative emotions and positive expectations. 85 male participants were randomly assigned to assume either a dominant posture (expansive, taking up more space with open limbs) or a subordinate posture (constrictive, taking up less space with closed limbs) while delivering a speech and performing difficult arithmetic tasks in front of two critical evaluators. Cortisol levels were assessed from saliva samples obtained before and after these stressful tasks. Dominant posture resulted in a larger cortisol response compared to the subordinate posture. Participants in the subordinate posture did not show the normative increase in cortisol observed in other studies using this standardized social-evaluative stress protocol. The finding that a subordinate posture decreases acute stress responses during negative social evaluation suggests that submissive strategies may be appropriate and adaptive in uncontrollable situations involving negative social evaluation. Submissiveness may diminish endocrine stress responses, which are hypothesized to have adverse effects on health in the long term. These findings have implications for developing strategies to help individuals deal with stressful social-evaluative situations while protecting their physical and mental health.

    Watkinson, Susan; Seewoodhary, Ramesh

    2017-12-06

    Red eye is a common ocular presentation in primary care, and there are several challenges that healthcare practitioners may encounter when caring for such patients. The main ocular conditions that can give rise to red eye are: primary acute angle closure glaucoma, acute iritis, dry eye, blepharitis and conjunctivitis. Red eye can be classified as sight-threatening or non-sight-threatening. Many patients presenting with painless red eye and normal vision usually recover well. However, when red eye is associated with pain, photophobia, watering and blurred vision, it is potentially sight-threatening and must be addressed urgently. Therefore, it is vital for healthcare practitioners to be able to undertake a careful assessment of the patient and make an accurate diagnosis early. This article provides an overview of the common causes of red eye encountered in general practice or an eye clinic. It discusses the nurse's role in the care and management of patients with red eye, with reference to patient assessment, the skills required to make an accurate diagnosis, treatment and health promotion. ©2017 RCN Publishing Company Ltd.

  4. Organization of eye bank

    International Nuclear Information System (INIS)

    Reddy, S.C.

    1999-01-01

    Comeal transplantation is the only method of combating the blindness due to corneal opacity caused by infections, malnutrition, trauma and hereditary diseases. Comeal blindness is more prevalent in the developing countries. The availability of the donor cornea, trained ophthalmic surgeons and microsurgery facilities are the key factors in restoring vision in-patients with comeal blindness. The eye bank organization is somewhat similar to that of blood bank. The eye bank should be located in a hospital or a medical centre in which a laboratory may be established for the evaluation and storage of donor tissue. The medical director (Ophthalmologist), technician, secretary and public relation officer are the persons who play an important role in the successful organization of eye bank. The function of the eye bank are procurement, assessment, processing, distribution of donor eyes/corneas, training of technicians/doctors, and conducting research related to storage of donor tissue and corneal transplantation. The necessary infrastructure required for the organization of an eye bank include separate accommodation area for the personnel and the laboratory, telephone, computer, refrigerator, laminar air flow hood. Slitlamp, specular microscope, storage media and equipment, instrument for enucleation of donor eyes, and a motor vehicle. The details of responsibilities of the staff of eye bank, source of donor eyes, suitability of donor material, procurement of the donor cornea, tissue assessment, storage and preservation, distribution of donor tissue, and limitation of eye bank will be discussed at the time of presentation

Although his general condition improved after intravenous acyclovir administration, the patient presented with visual loss in both eyes 4 days after admission. Visual acuity in his right eye was 20/200 and his left eye had light perception alone. Both eyes showed panretinal arteritis diagnosed as acute retinal necrosis. Panretinal photocoagulation was performed for both eyes. Progression of retinal detachment was prevented in both eyes; however, visual acuity of the left eye was totally lost because of neovascular glaucoma. Visual acuity of the right eye recovered to 20/20.Conclusion: Although cases of bilateral acute retinal necrosis have been reported after herpetic encephalitis, this condition is rare after herpetic meningitis. Prophylactic acyclovir therapy and early panretinal photocoagulation may prevent retinal detachment and improve the prognosis. Neurologists and ophthalmologists should be aware that not only herpetic encephalitis but also herpetic meningitis can lead to acute retinal necrosis within a very short interval.Keywords: acute retinal necrosis, herpetic meningitis, herpes simplex, varicella zoster virus

    1976-01-01

    A new packaged assembly comprising an eye bath and eye lotion is described. The eye bath is shaped for application to the eye; it has a rim portion formed so as to provide a smooth skin-contacting surface and is sealed to a lid at a position removed from the skin-contacting area. The eye bath is formed in a sterile condition and aseptically filled to an appropriate level with eye lotion by a blow moulding process. The eye bath and its contents are sterilised after sealing by radioactive sterilsation. This packaged assembly is an improvement over previous eye bath assemblies in that it allows the eye bath to be used in a sterile form. It is also more comfortable and convenient to use than other sterile forms of eye treatment such as eye drops or jets of eye wash. Furthermore, bathing the eye provides a more prolonged treatment.

The theory is that pervasive eye disease diminished the incentive to accumulate skills, thereby delaying the fertility...... transition and the take-off to sustained economic growth. In order to estimate the influence from eye disease incidence empirically, we draw on an important fact from the field of epidemiology: Exposure to solar ultraviolet B radiation (UVB-R) is an underlying determinant of several forms of eye disease...

  16. Choroidal Thickness in Eyes with Fuchs Uveitis Syndrome.

    Kardes, Esra; Sezgin Akçay, Betül Ilkay; Unlu, Cihan; Ergin, Ahmet

    2017-04-01

    This study measured the macular thickness, peripapillary retinal nerve fiber layer (RNFL) thickness, subfoveal choroidal thickness (SFCT), and ganglion cell complex (GCC) thickness in eyes with Fuchs uveitis syndrome (FUS). In total, 25 patients with unilateral FUS were enrolled. The diagnosis of FUS was based on the presence of several of the following clinical features: absence of acute symptoms and ciliary injection; small to medium-sized and stellate keratic precipitates (KP) diffusely scattered on the entire corneal endothelium; chronic low-grade anterior chamber inflammation; iris stromal atrophy with or without heterochromia; lack of posterior synechiae; iris nodules; and vitreous cells and debris. Spectral domain optical coherence tomography (SD-OCT; RTVue-100 OCT) was used to obtain the measurements. The SFCT, RNFL thickness, macular retinal thickness, and GCC thickness of the eyes with FUS were measured and compared with those of the uninvolved fellow eyes. A paired samples t-test was used for statistical analyses. A value of pHeterochromia was observed in 24% of the eyes, iris nodules in 36% of the eyes, lens opacity in 44% of the eyes, and vitreous cells and debris in 88% of the eyes. The mean SFCT was significantly thinner in eyes with FUS (296.47 ± 32.29 µm) than in the fellow eyes without FUS (324.47 ± 26.73 µm; p = 0.001). The mean average GCC thickness was found to be 101.09 ± 5.46 µm in eyes with FUS and 103.80 ± 6.65 µm in eyes without FUS (p = 0.023). There were no significant differences in the mean RNFL and macular thickness values. We detected subfoveal choroidal thinning in eyes with FUS when compared with the uninvolved fellow eyes. In our opinion, thinning of the SFCT in FUS might be associated with autoimmune responses and chronic inflammatory processes.

  3. Ultraviolet eye radiation: the problem and solutions.

    Science.gov (United States)

    Sheedy, James E; Edlich, Richard F

    2004-01-01

    Ultraviolet radiation (UVR) can cause damage to the eyes. Some of the damage is acute, with immediate signs and symptoms, while some of the damage is the result of cumulative or long-term UVR exposure. Because the most common source of UVR is the sun, individuals who are exposed to sunny environments should be advised to protect themselves properly. Individuals should be counseled about proper eye protection from UVR in sunlight. It is important to know when eye protection is indicated. Protection involves wearing a wide-brimmed hat or cap and well-designed sunglasses. The advisable sunglass features include the following: large eye size with side protection, less than 1% UV-B transmittance, less than 1% UV-A transmittance, gray or near-neutral colored lenses, good optical quality, and visible transmittance selected for visual comfort. Some clear spectacles or contact lenses also provide good levels of UV protection. When selecting sunglasses, it is always helpful to consult your eye care specialist.

    2010-06-07

    Compound eye is a new field of research about miniaturizing imaging systems. We for the first time introduce a dual compound eye that contains three micro lens arrays with aspheric surfaces. The designed dual compound eye in one state is a superposition system in which each channel images all of field of view of the system. With adding a field stop we have decreased the stray light. MTF of ideal superposition compound eye calculated. Also with changing field stop the system is converted to an apposition compound eye in which each channel images only a part of total field of view and so the field of view is larger than that of superposition type.

  5. Advocacy for eye care

    Directory of Open Access Journals (Sweden)

    Thulasiraj D Ravilla

    2012-01-01

    Full Text Available The effectiveness of eye care service delivery is often dependant on how the different stakeholders are aligned. These stakeholders range from the ministries of health who have the capacity to grant government subsidies for eye care, down to the primary healthcare workers who can be enrolled to screen for basic eye diseases. Advocacy is a tool that can help service providers draw the attention of key stakeholders to a particular area of concern. By enlisting the support, endorsement and participation of a wider circle of players, advocacy can help to improve the penetration and effectiveness of the services provided. There are several factors in the external environmental that influence the eye care services - such as the availability of trained manpower, supply of eye care consumables, government rules and regulations. There are several instances where successful advocacy has helped to create an enabling environment for eye care service delivery. Providing eye care services in developing countries requires the support - either for direct patient care or for support services such as producing trained manpower or for research and dissemination. Such support, in the form of financial or other resources, can be garnered through advocacy.

    The major part of the eye consists of water . Continuous movement of water and ions between the ocular compartments and to the systemic circulation is pivotal for many physiological functions in the eye. The movement of water facilitates removal of the many metabolic products of corneal-, ciliary...... pressure. In the retina, water is transported into the vitreous body and across the retinal pigment epithelium to regulate the extracellular environment and the hydration of the retina. Aquaporins (AQPs ) take part in the water transport throughout the eye....

  8. Multimodal eye recognition

    Science.gov (United States)

    Zhou, Zhi; Du, Yingzi; Thomas, N. L.; Delp, Edward J., III

    2010-04-01

    Multimodal biometrics use more than one means of biometric identification to achieve higher recognition accuracy, since sometimes a unimodal biometric is not good enough used to do identification and classification. In this paper, we proposed a multimodal eye recognition system, which can obtain both iris and sclera patterns from one color eye image. Gabor filter and 1-D Log-Gabor filter algorithms have been applied as the iris recognition algorithms. In sclera recognition, we introduced automatic sclera segmentation, sclera pattern enhancement, sclera pattern template generation, and sclera pattern matching. We applied kernelbased matching score fusion to improve the performance of the eye recognition system. The experimental results show that the proposed eye recognition method can achieve better performance compared to unimodal biometric identification, and the accuracy of our proposed kernel-based matching score fusion method is higher than two classic linear matching score fusion methods: Principal Component Analysis (PCA) and Linear Discriminant Analysis (LDA).

    Science.gov (United States)

    Wilhelmus, K R

    2001-01-01

    Hundreds of substances are used daily that can damage eyesight. People's eyes are open to accidental or intentional exposure during the production, transportation, use, and disposal of chemical preparations. Ensuring the safety of consumer products was born during the mid twentieth century in the aftermath of chemical warfare research, and was motivated by the hazards of unsafe cosmetics. Justified by an exigency for public protection, the Draize eye test became a governmentally endorsed method to evaluate the safety of materials meant for use in or around the eyes. The test involves a standardized protocol for instilling agents onto the cornea and conjunctiva of laboratory animals. A sum of ordinal-scale items of the outer eye gives an index of ocular morbidity. Advances in ocular toxicology are challenging the validity, precision, relevance, and need of the Draize eye test. Preclinical product-safety tests with rabbits and other mammals also raise ethical concerns of animal wellbeing. Some use the Draize test as a rallying point for how animals are treated in science and industry. A battery of cellular systems and computer models aim to reduce and ultimately to replace whole-animal testing. Molecular measures of ocular toxicity may eventually allow comprehensive screening in humans. The Draize eye test was created and refined for humanitarian reasons and has assuredly prevented harm. Its destiny is to be progressively supplanted as in vitro and clinical alternatives emerge for assessing irritancy of the ocular surface.

    To investigate the prevalence of, and factors associated with, errors in neuroretinal rim measurement by Cirrus high-definition (HD) spectral-domain optical coherence tomography (OCT) in myopic eyes. Neuroretinal rim thicknesses of 255 myopic eyes were measured by Cirrus HD-OCT. The prevalence of, and factors associated with, optic disc margin detection error and cup margin detection error were assessed by analysing 72 cross-sectional optic nerve head (ONH) images obtained at 5° intervals for each eye. Among the 255 eyes, 45 (17.6%) had neuroretinal rim measurement errors; 29 (11.4%) had optic disc margin detection errors at the temporal (16 eyes), superior (11 eyes), and inferior (2 eyes) quadrants; 19 (7.5%) showed cup margin detection errors at the nasal (17 eyes) and temporal (2 eyes) quadrants; and 3 (1.2%) had both disc and cup margin detection errors. Errors in detection of temporal optic disc margin were associated with presence of parapapillary atrophy (PPA), higher myopia, and greater axial length (AL) (perrors were associated with vitreous opacities attached to the ONH surface or acute cup slope angles (pErrors in neuroretinal rim measurement by Cirrus HD-OCT were found in myopic eyes, especially in eyes with PPA, higher myopia, greater AL, vitreous opacity or acute cup slope angle. These findings should be considered when interpreting neuroretinal rim thickness measured by Cirrus HD-OCT.

  17. Autologous serum eye drops for severe dry eye syndrome in a patient with chronic graft-versus-host disease: a case report.

    Science.gov (United States)

    Mixon, Bill; Mixon, Jan; Isbey, Edward K; Sprinkle, Shari

    2014-01-01

    We present the case of a 49-year-old woman with severe dry eye syndrome caused by chronic graft-versus-host disease that developed after an allogeneic hematopoietic transplant to treat acute myelogenous leukemia. After the use of commercially manufactured products for the treatment of dry eye failed to relieve her photosensitivity, blurred. vision, and severe bilateral ocular pain, she benefitted significantly from therapy with compounded autologous serum eye drops. Comments from that patient are included in this report, as are a formulation for the preparation of autologous eye drops and suggestions for their safe and effective use.

    Eye movements provide insights about a wide range of brain functions, from sensorimotor integration to cognition; hence, the measurement of eye movements is an important tool in neuroscience research. We describe a method, based on magnetic sensing, for measuring eye movements in head-fixed and freely moving mice. A small magnet was surgically implanted on the eye, and changes in the magnet angle as the eye rotated were detected by a magnetic field sensor. Systematic testing demonstrated high resolution measurements of eye position of coil and video-oculography methods. Most notably, it provides the first method for reliable, high-resolution measurement of eye movements in freely moving mice, revealing increased eye movements and altered binocular coordination compared to head-fixed mice. Overall, magnetic eye tracking provides a lightweight, inexpensive, easily implemented, and high-resolution method suitable for a wide range of applications.

  11. NGC6543: Cat's Eye and Bull's Eye

    Science.gov (United States)

    Balick, B.; Wilson, J. M.

    2000-05-01

    Deep Hubble images of NGC 6543 reveal a series of regularly spaced circular concentric ``rings'' that surround the famous Cat's Eye nebula. The rings seen in the lines of Hα , [O III], and [N II] but not the continuum. These photoionized rings are almost certainly the result of periodic spherical mass pulsations by the nucleus before the Cat's Eye formed. A good fit to the observed Hα surface brightness distribution is obtained if the bubbles were ejected with constant mass, thickness, and ejection velocity. The model can be used to estimate the total mass of the rings, ~ 0.1M⊙ , which lies between that of the core ( ~ 0.05 M⊙ ) and the surrounding halo ( ~ 0.5 M⊙ ). Assuming an ejection speed of 10 km s-1 the interpulse period is 1500 +/- 300 y, the same as the expansion age of the core itself. Hubble images of other planetaries displayed on the poster, IC 418, NGC 7027, and Hubble 5 (a bipolar) show similar sets of multiple concentric rings. Hence, it appears, regular isotropic AGB mass pulses often precede the formation of brighter and more complex PN cores. However, the interpulse time scale, ~ 103 y, is a serious problem for extant models of core thermal pulses and surface pulsations. The cores of PNe seem to form in an abrupt change of mode of mass loss, as predicted by disrputive binary companion merger models.

  15. Unilateral Amblyopia Affects Two Eyes: Fellow Eye Deficits in Amblyopia.

    Science.gov (United States)

    Meier, Kimberly; Giaschi, Deborah

    2017-03-01

    Unilateral amblyopia is a visual disorder that arises after selective disruption of visual input to one eye during critical periods of development. In the clinic, amblyopia is understood as poor visual acuity in an eye that was deprived of pattern vision early in life. By its nature, however, amblyopia has an adverse effect on the development of a binocular visual system and the interactions between signals from two eyes. Visual functions aside from visual acuity are impacted, and many studies have indicated compromised sensitivity in the fellow eye even though it demonstrates normal visual acuity. While these fellow eye deficits have been noted, no overarching theory has been proposed to describe why and under what conditions the fellow eye is impacted by amblyopia. Here, we consider four explanations that may account for decreased fellow eye sensitivity: the fellow eye is adversely impacted by treatment for amblyopia; the maturation of the fellow eye is delayed by amblyopia; fellow eye sensitivity is impacted for visual functions that rely on binocular cortex; and fellow eye deficits reflect an adaptive mechanism that works to equalize the sensitivity of the two eyes. To evaluate these ideas, we describe five visual functions that are commonly reported to be deficient in the amblyopic eye (hyperacuity, contrast sensitivity, spatial integration, global motion, and motion-defined form), and unify the current evidence for fellow eye deficits. Further research targeted at exploring fellow eye deficits in amblyopia will provide us with a broader understanding of normal visual development and how amblyopia impacts the developing visual system.

In the case of mechanical globe injuries, it is important to classify the injury according to the Birmingham Eye Trauma Terminology System (BETTS and write it down in the patient’s notes; this will help to ensure that everyone involved in caring for the patient will have a consistent understanding of the type of injury. The resulting uniformity of terminology also helps with research, making it possible to compare data and do audits of injuries – which is essential for prevention.

    Molitor, Robert J; Ko, Philip C; Ally, Brandon A

    2015-01-01

    A growing body of literature has investigated changes in eye movements as a result of Alzheimer's disease (AD). When compared to healthy, age-matched controls, patients display a number of remarkable alterations to oculomotor function and viewing behavior. In this article, we review AD-related changes to fundamental eye movements, such as saccades and smooth pursuit motion, in addition to changes to eye movement patterns during more complex tasks like visual search and scene exploration. We discuss the cognitive mechanisms that underlie these changes and consider the clinical significance of eye movement behavior, with a focus on eye movements in mild cognitive impairment. We conclude with directions for future research.

    Parents of children who presented for a pediatrics appointment responded to a clinical vignette that described a child with symptoms consistent with acute viral conjunctivitis. In a 2 × 2 randomized survey design, the physician in the vignette either used the term "pink eye" or "eye infection" to describe the symptoms, and either told parents that antibiotics are likely ineffective at treating the symptoms or did not discuss effectiveness. When the symptoms were referred to as "pink eye," parents remained interested in antibiotics, despite being informed about their ineffectiveness. By contrast, when the symptoms were referred to as an "eye infection," information about antibiotic ineffectiveness significantly reduced interest, Mdiff = 1.63, P pink eye" label also thought that the symptoms were more contagious and were less likely to believe that their child could go to child care, compared with parents who received the "eye infection" label, Mdiff = 0.37, P = .38. © The Author(s) 2015.

  6. Hydration, fluid regulation and the eye: in health and disease.

    Sherwin, Justin C; Kokavec, Jan; Thornton, Simon N

    2015-11-01

    Variation in systemic hydration status, namely chronic systemic hypohydration or dehydration, can influence the development of several chronic non-ophthalmic diseases. Owing to the eye's high water content and unique system of fluid regulation, we hypothesized that hydration status may affect the eye in health and disease states. Therefore, we performed a systematic review of the current evidence implicating changes in hydration and their association with ocular physiology and morphological characteristics. We also reviewed relevant clinical correlations of changes in hydration and major common eye diseases. Our findings suggest that systemic hydration status broadly affects a variety of ocular pathophysiologic processes and disease states. For example, dehydration may be associated with development of dry eye syndrome, cataract, refractive changes and retinal vascular disease. On the other hand, excessive hydration is associated with some ocular diseases. Tear fluid osmolarity may be an effective marker of systemic hydration status. Recent studies implicate chronic renin-angiotensin-aldosterone system activation in the pathogenesis of diabetic retinopathy and glaucoma but also suggest its antagonism may be a useful therapeutic target. Our findings indicate that assessment of hydration status may be an important consideration in the management of patients with chronic eye diseases and undergoing eye surgery. Further research investigating the role of acute and chronic changes in hydration in individuals with and without ocular disease is warranted. © 2015 Royal Australian and New Zealand College of Ophthalmologists.

  8. Effects of benzydamine eye drops on the rabbit's eye reaction to surgical, physical, and chemical stimuli

    Energy Technology Data Exchange (ETDEWEB)

    Tomazzoli, L.; Bonora, A.; Luparini, M.R.; Durando, L.; Ciarniello, M.G.; Cioli, V.; Bonomi, L.

    The effects of benzydamine eye drops on the ocular reaction to different irritating stimuli in rabbits are reported. Benzydamine at the concentration of 0.1% reduces inflammatory tissue changes induced by AgNO3 burning of the cornea and inhibits the blood-aqueous barrier breakdown due to peripheral iridectomy or laser irradiation of the iris. Benzydamine reduces the aqueous PGE2 concentration to a similar extent as a 0.5% commercially available eye drop formulation of piroxicam. This result is in contrast with previous in vitro results demonstrating that benzydamine is devoid of any effects on PG synthesis. The possibility that PGE2 reduction is an indirect effect due to other biochemical activities of benzydamine is discussed. In the normal eye benzydamine manifests a local anaesthetic effect which is not accompanied by irritative changes in the anterior segment of the eye, changes in the intraocular pressure or pupillary size. It is suggested that in the clinical use of benzydamine eye drops the local anaesthetic activity may contribute to reducing both the neurogenic component of ocular inflammation and acute pain following injuries to the eye.

    ïve Bayesian likelihood-based classification approaches. To provide flexibility in SNP-based eye color predictive tests in forensic applications we modified an online Bayesian classifier, originally developed for genetic ancestry analysis, to provide a straightforward system to assign eye color likelihoods from a SNP profile combining additional informative markers from the predictors analyzed by our study plus those of Walsh and Mengel-From. Two advantages of the online classifier is the ability to submit incomplete SNP profiles, a common occurrence when typing challenging DNA, and the ability to handle physically linked SNPs showing independent effect, by allowing the user to input frequencies from SNP pairs or larger combinations. This system was used to include the submission of frequency data for the SNP pair rs12913832 and rs1129038: indicated by our study to be the two SNPs most closely associated to eye color.

  11. Studies on exploratory eye movement.

    2009-03-01

    This paper describes the pioneering studies on eye movements by Prof. Takuya Kojima, which clarified the scarcity of adjustability of alertness level in schizophrenia. Shimazono first thought that closed-eye eye movement may provide objective and physiological indicator for brain activities during awake state. Prof. Kojima thought that depressive patients may also have latent inner tension and was also intrigued by the contrast of the scarcity of exploratory eye movement in schizophrenic patients. He found out that depressive patients are tense at rest but that accustomization takes place in them, while accustomization does not take place in schizophrenic patients. Isse researched on closed-eye eye movements in relation with alertness and disturbance of consciousness. Prof. Kojima invented eye camera to measure the exploratory eye movement and created Responsive Search Score (RSS), an indicator of the parts which the subject covers during the responsive search. Prof. Kojima's research on differentiation of schizophrenic patients was carried out as WHO and the result was replicated in different ethnicities. Clinical molecular genetic studies suggest that RSS reflects the disposition of susceptibility for schizophrenia and possible linkage between RSS and chromosome 22q. Brain imaging studies showed correlation between RSS and the volume of the right parietal eye field, right frontal eye field including the right supplementary eye field and the right inferior frontal gyrus. Based on these findings Prof. Kojima invented an apparatus which can monitor eye movements and show diagnostic sensitivity 75% and specificity 80% for schizophrenia. The apparatus is expected to be applied clinically in the future.

  15. Reading between eye saccades.

    Directory of Open Access Journals (Sweden)

    Caroline Blais

    Full Text Available BACKGROUND: Skilled adult readers, in contrast to beginners, show no or little increase in reading latencies as a function of the number of letters in words up to seven letters. The information extraction strategy underlying such efficiency in word identification is still largely unknown, and methods that allow tracking of the letter information extraction through time between eye saccades are needed to fully address this question. METHODOLOGY/PRINCIPAL FINDINGS: The present study examined the use of letter information during reading, by means of the Bubbles technique. Ten participants each read 5,000 five-letter French words sampled in space-time within a 200 ms window. On the temporal dimension, our results show that two moments are especially important during the information extraction process. On the spatial dimension, we found a bias for the upper half of words. We also show for the first time that letter positions four, one, and three are particularly important for the identification of five-letter words. CONCLUSIONS/SIGNIFICANCE: Our findings are consistent with either a partially parallel reading strategy or an optimal serial reading strategy. We show using computer simulations that this serial reading strategy predicts an absence of a word-length effect for words from four- to seven letters in length. We believe that the Bubbles technique will play an important role in further examining the nature of reading between eye saccades.

  16. Laser eye injuries.

    Barkana, Y; Belkin, M

    2000-01-01

    Laser instruments are used in many spheres of human activity, including medicine, industry, laboratory research, entertainment, and, notably, the military. This widespread use of lasers has resulted in many accidental injuries. Injuries are almost always retinal, because of the concentration of visible and near-infrared radiation on the retina. The retina is therefore the body tissue most vulnerable to laser radiation. The nature and severity of this type of retinal injury is determined by multiple laser-related and eye-related factors, the most important being the duration and amount of energy delivered and the retinal location of the lesion. The clinical course of significant retinal laser injuries is characterized by sudden loss of vision, often followed by marked improvement over a few weeks, and occasionally severe late complications. Medical and surgical treatment is limited. Laser devices hazardous to the human eye are currently in widespread use by armed forces. Furthermore, lasers may be employed specifically for visual incapacitation on future battlefields. Adherence to safety practices effectively prevents accidental laser-induced ocular injuries. However, there is no practical way to prevent injuries that are maliciously inflicted, as expected from laser weapons.

    Ocular scintigraphy can now be carried out with several tracers: 131 I diiodofluorescein and sup(99m)Tc, hypervascularisation indicators; 131 I iodinated chloroquine, melanoma selective. The detector used is an Anger scintillation camera coupled to a multiparameter analysis chain or a computer. The ''pin-hole'' type collimator, which has a stenopaeic opening in front of each eye, is adaptable to any inter-pupil distance. The very simple scintigraphic procedure is described. The results, taken from two statistical studies on 198 and 80 patients respectively, concern the main types of eye disease encountered: malignant melanic tumours, other tumours, metastases, choroiditis, idiopathic detachments of the retina etc... The interpretation of the scintigrams and the problems involved are considered. Finally the main indications of the method are defined with emphasis on the possibilities of double scintigraphy, diiodofluorescein only showing up the hypervascularisation often associated with the tumour whereas iodinated chloroquine, when the result is positive, points to the presence of a malignant melanoma [fr

  18. Eye Surgery Light

    Science.gov (United States)

    1978-01-01

    During eye surgery, the surgeon uses an illuminating instrument called an opthalmoscope for close examination of the retina or the interior of the eye. Ordinarily, electric power for the head-mounted light is supplied through a cord from an overhead swivel arm or a floor pedestal. Within limits of cord length and swivel arm movement, the surgeon has considerable freedom of motion. But when more than one opthalmoscope is involved, tangling and interference of the power cords becomes a problem. St. Luke's Hospital, Cleveland, Ohio asked Lewis Research Center for assistance in finding a solution. Lewis responded with a battery-powered system that totally frees the surgeon of attached cords and swivels. Borrowing from space technology, Lewis used small, lightweight nickel-cadmium batteries that can deliver high intensity light for an hour and can be recharged overnight. The Opthalmoscope Powerpack consists of eight batteries in three containers affixed to a webbed belt, and a novel on-off switch equipped with a springloaded plexiglass "flapper." The belt pack is worn underneath the surgical gown and the flapper permits the doctor to activate the switch by elbow pressure. Lewis built five units and they have been in service at St. Luke's Hospital for a year. Used for routine examinations as well as for surgery, they have demonstrated excellent reliability.

    Eye banks have procured, processed and stored donor corneas for decades. In parallel, new techniques have emerged employing allogeneic transplantation of various cells and tissues from the eye banks. This progress is a consequence of increased knowledge of stem cells, cell kinetics and immunological aspects and improved techniques for cell culturing, tissue storage and microsurgery. Review article on available transplants for treating eye diseases, based on experience with eye banking, clinical ophthalmological practice, own research and literature retrieved from PubMed, Medline and www.google.com. Treatment techniques for eye diseases, which require biological material for grafting, need efficient eye banks for continuous supply of donor material of high quality. New Norwegian legislation, based on implementation of EU Directive 2004/23/EC, demands authorization of all eye banks. The EU Directive sets high and rigorous standards for quality and safety for donation, procurement, testing, processing, storage and distribution of tissues and cells. Well-run eye banks are of great importance for modern treatment of patients suffering from eye diseases and for progress and research in ophthalmology.

    To investigate, through ultrasound biomicroscopy images, the presence of plateau iris configuration in eyes with narrow-angle from patients with open-angle glaucoma and in eyes with previous acute primary angle-closure and compare the biometric features of eyes with plateau iris configuration with those of normal eyes. Ultrasound biomicroscopic images from 196 patients with open-angle glaucoma and narrow-angle and 32 patients with acute primary angle-closure were retrospectively analyzed. The inclusion and specific criteria for the diagnosis of plateau iris configuration was the presence of an anterior positioning of the ciliary processes, supporting the peripheral iris so that it was parallel to the trabecular meshwork; the iris root had a steep rise from its insertion point, followed by a downward angulation from the corneoscleral wall; presence of a central flat iris plane; an absent (complete plateau iris configuration) or partially absent (incomplete plateau iris configuration) ciliary sulcus. The ultrasound biomicroscopic parameters were compared between complete and incomplete plateau iris configuration. The same parameters of both groups were compared with those of normal eyes. The following measurements were performed: anterior chamber depth; angle opening distance at 500 microm from the scleral spur; peripheral iris thickness at 500 microm from the scleral spur; iris-ciliary process distance; trabecular-ciliary process distance and angle recess area. Plateau iris configuration was found in 33 eyes of 20 (10.2%) out of 196 patients with open-angle glaucoma and narrow-angle and in 4 eyes of 2 (6.3%) out of 32 patients with acute primary angleclosure. Seventeen (77.3%) patients with plateau iris configuration were female and 5 (22.7%) male. Twenty-three (62.2%) out of 37 eyes had complete plateau iris configuration, and 14 (37.8%) had incomplete plateau iris configuration. Complete and incomplete plateau iris configuration presented similar biometric

  7. Wavefront Derived Refraction and Full Eye Biometry in Pseudophakic Eyes.

    Directory of Open Access Journals (Sweden)

    Xinjie Mao

    Full Text Available To assess wavefront derived refraction and full eye biometry including ciliary muscle dimension and full eye axial geometry in pseudophakic eyes using spectral domain OCT equipped with a Shack-Hartmann wavefront sensor.Twenty-eight adult subjects (32 pseudophakic eyes having recently undergone cataract surgery were enrolled in this study. A custom system combining two optical coherence tomography systems with a Shack-Hartmann wavefront sensor was constructed to image and monitor changes in whole eye biometry, the ciliary muscle and ocular aberration in the pseudophakic eye. A Badal optical channel and a visual target aligning with the wavefront sensor were incorporated into the system for measuring the wavefront-derived refraction. The imaging acquisition was performed twice. The coefficients of repeatability (CoR and intraclass correlation coefficient (ICC were calculated.Images were acquired and processed successfully in all patients. No significant difference was detected between repeated measurements of ciliary muscle dimension, full-eye biometry or defocus aberration. The CoR of full-eye biometry ranged from 0.36% to 3.04% and the ICC ranged from 0.981 to 0.999. The CoR for ciliary muscle dimensions ranged from 12.2% to 41.6% and the ICC ranged from 0.767 to 0.919. The defocus aberrations of the two measurements were 0.443 ± 0.534 D and 0.447 ± 0.586 D and the ICC was 0.951.The combined system is capable of measuring full eye biometry and refraction with good repeatability. The system is suitable for future investigation of pseudoaccommodation in the pseudophakic eye.

    1999-11-01

    The percentage of penetrating eye injuries in war has increased significantly in this century compared with the total number of combat injuries. With the increasing use of fragmentation weapons and possibly laser weapons on the battle-field in the future, the rate of eye injuries may exceed the 13% of the total military injuries found in Operations Desert Storm/Shield. During the Iran-Iraq War (1980-1988), eye injuries revealed that retained foreign bodies and posterior segment injuries have an improved prognosis in future military ophthalmic surgery as a result of modern diagnostic and treatment modalities. Compared with the increasing penetrating eye injuries on the battlefield, advances in ophthalmic surgery are insignificant. Eye armor, such as visors that flip up and down and protect the eyes from laser injury, needs to be developed. Similar eye protection is being developed in civilian sportswear. Penetrating eye injury in the civilian sector is becoming much closer to the military model and is now comparable for several reasons.

    Full Text Available Lipid autacoids have well-established key roles in physiology and pathophysiology. Eicosanoids derived from ω-6 arachidonic acid (AA have long been recognized for their roles in cardiovascular and renal functions, and vascular tone, as well as regulating inflammatory and immune functions. It is now appreciated that AA is a substrate for generating lipid mediators with anti-inflammatory and proresolving properties, namely lipoxins (i.e., LXA4, which are an integral component for the successful execution of beneficial and essential acute inflammatory responses. In addition to AA, the ω-3 polyunsaturated fatty acids (PUFAs eicosapentaenoic acid (EPA and docosahexaenoic acid (DHA also serve as substrates to generate potent and protective autacoids, such as resolvins and neuroprotectin (i.e., NPD1, respectively. These ω-3–derived signals may mediate the remarkable protective action of essential dietary ω-3 PUFAs. Formation and bioactivity of lipid mediators in the eye are relatively unexplored and of considerable interest, as the eye contains highly specialized tissues, including the transparent avascular and immune-privileged cornea, and the neuro-retina. A rapidly emerging field has identified key biosynthetic enzymes, receptors, and temporally defined endogenous formation of ω-3– and ω-6–derived protective lipid circuits in the eye. Protective endogenous roles of LXA4 and NPD1 have been established utilizing lipidomic analysis, knockout mice, and pharmacological, genetic, and dietary manipulation, providing compelling evidence that these intrinsic lipid autacoid circuits play essential roles in restraining inflammation, promoting wound healing, inhibiting pathological angiogenesis, and providing neuroprotection in the delicate visual axis.

    Mancebo, Axel; Hernández, Osvaldo; González, Yana; Aldana, Lizet; Carballo, Onelio

    2008-01-01

    The determination of acute eye and skin irritation is included in international regulatory requirements for the testing of chemicals, because of the possibility of exposure during the production, transport, marketing, and disposal of products. Although there have been some advances in the areas of refinement and reduction, no single battery of tests has emerged as being acceptable as a complete replacement for the conventional Draize rabbit eye and skin irritation tests. Currently, dermal irritation and ocular irritation are generally evaluated in a sequential manner in the context of tiered assessment strategies. In this work, we show how 14 products, mostly designed to be used in agriculture, were evaluated in the Center of Experimental Toxicology of the Center for the Production of Laboratory Animals (Centro Nacional para la Producción de Animales de Laboratorio; CENPALAB) in order to assess their acute dermal and ocular effects. The performed studies include the acute dermal toxicity test, the acute dermal irritation/corrosion test, the hen's egg test-chorioallantoic membrane (HET-CAM) method, and the acute eye irritation/corrosion test. In general, it could be concluded that of the 14 products assessed, none of them showed systemic effects, but local reactions mainly to the eyes. The most significant effects were apparently related to the effects of azadirachtin, an active principle of 2 tested neem derivatives.

    A full-term female baby, a product of non-consanguineous marriage, was born at 37 weeks of gestation with a birth weight of 2.08 kg. Antenatal scan at 31 weeks revealed complex congenital heart disease with a hypoplastic right ventricle, pulmonary atresia and an intact septum. Immediately after birth, the infant was shifted to the nursery and was started on intravenous fluids and infusion prostaglandin E1 (Alprostidil). On examination, she had microcephaly, periorbital puffiness, a long philtrum, a broad nasal bridge and retrognathia, up slanting palpebral fissures, widely spaced nipples, a sacral dimple and right upper limb postaxial polydactyly. Postnatal echocardiography confirmed a large ostium secundum atrial septal defect with left to right shunt, right ventricle hypoplasia, pulmonary atresia with an intact septum and a large vertical patent ductus arteriosus. Ophthalmological examination showed a bilateral chorioretinal coloboma sparing disc and fovea. Karyotyping showed an extra small marker chromosome suggestive of the Cat eye syndrome. 2014 BMJ Publishing Group Ltd.

    2016-10-19

    Although much is known about the regenerative capacity of retinal ganglion cells, very significant barriers remain in our ability to restore visual function following traumatic injury or disease-induced degeneration. Here we summarize our current understanding of the factors regulating axon guidance and target engagement in regenerating axons, and review the state of the field of neural regeneration, focusing on the visual system and highlighting studies using other model systems that can inform analysis of visual system regeneration. This overview is motivated by a Society for Neuroscience Satellite meeting, "Reconnecting Neurons in the Visual System," held in October 2015 sponsored by the National Eye Institute as part of their "Audacious Goals Initiative" and co-organized by Carol Mason (Columbia University) and Michael Crair (Yale University). The collective wisdom of the conference participants pointed to important gaps in our knowledge and barriers to progress in promoting the restoration of visual system function. This article is thus a summary of our existing understanding of visual system regeneration and provides a blueprint for future progress in the field.

  2. Greek mythology: the eye, ophthalmology, eye disease, and blindness.

    Trompoukis, Constantinos; Kourkoutas, Dimitrios

    2007-06-01

    In distant eras, mythology was a form of expression used by many peoples. A study of the Greek myths reveals concealed medical knowledge, in many cases relating to the eye. An analysis was made of the ancient Greek texts for mythological references relating to an understanding of vision, visual abilities, the eye, its congenital and acquired abnormalities, blindness, and eye injuries and their treatment. The Homeric epics contain anatomical descriptions of the eyes and the orbits, and an elementary knowledge of physiology is also apparent. The concept of the visual field can be seen in the myth of Argos Panoptes. Many myths describe external eye disease ("knyzosis"), visual disorders (amaurosis), and cases of blinding that, depending on the story, are ascribed to various causes. In addition, ocular motility abnormalities, congenital anomalies (cyclopia), injuries, and special treatments, such as the "licking" method, are mentioned. The study of mythological references to the eye reveals reliable medical observations of the ancient Greeks, which are concealed within the myths.

  3. Eye Absence Does Not Regulate Planarian Stem Cells during Eye Regeneration.

    Science.gov (United States)

    LoCascio, Samuel A; Lapan, Sylvain W; Reddien, Peter W

    2017-02-27

    Dividing cells called neoblasts contain pluripotent stem cells and drive planarian flatworm regeneration from diverse injuries. A long-standing question is whether neoblasts directly sense and respond to the identity of missing tissues during regeneration. We used the eye to investigate this question. Surprisingly, eye removal was neither sufficient nor necessary for neoblasts to increase eye progenitor production. Neoblasts normally increase eye progenitor production following decapitation, facilitating regeneration. Eye removal alone, however, did not induce this response. Eye regeneration following eye-specific resection resulted from homeostatic rates of eye progenitor production and less cell death in the regenerating eye. Conversely, large head injuries that left eyes intact increased eye progenitor production. Large injuries also non-specifically increased progenitor production for multiple uninjured tissues. We propose a model for eye regeneration in which eye tissue production by planarian stem cells is not directly regulated by the absence of the eye itself. Copyright © 2017 Elsevier Inc.

    Full Text Available Purpose: The aim of this study is to identify quality indicators of the eye bank and validate their effectivity. Methods: Adverse reaction rate, discard rate, protocol deviation rate, and compliance rate were defined as Quality Indicators of the eye bank. These were identified based on definition of quality that captures two dimensions – “result quality” and “process quality.” The indicators were measured and tracked as part of quality assurance (QA program of the eye bank. Regular audits were performed to validate alignment of standard operating procedures (SOP with regulatory and surgeon acceptance standards and alignment of activities performed in the eye bank with the SOP. Prospective study of the indicators was performed by comparing their observed values over the period 2011–2016. Results: Adverse reaction rate decreased more than 8-fold (from 0.61% to 0.07%, discard rate decreased and stabilized at 30%, protocol deviation rate decreased from 1.05% to 0.08%, and compliance rate reported by annual quality audits improved from 59% to 96% at the same time. In effect, adverse reaction rate, discard rate, and protocol deviation rate were leading indicators, and compliance rate was the trailing indicator. Conclusion: These indicators fulfill an important gap in available literature on QA in eye banking. There are two ways in which these findings can be meaningful. First, eye banks which are new to quality measurement can adopt these indicators. Second, eye banks which are already deeply engaged in quality improvement can test these indicators in their eye bank, thereby incorporating them widely and improving them over time.

  10. Eye safe laser range finders

    International Nuclear Information System (INIS)

    Snir, M.; Margaliot, M.; Amitzi, A.

    2004-01-01

    During the 1970's, Ruby (Q switched) laser based range finders with a wavelength of 694nm were first used. These lasers operated in a pulse mode within the visible light range and produced a risk for the eye retina. The laser beam striking the macula could damage the eye and might cause blindness. Over the years, Nd:YAG (Q switched) lasers were developed (operating at 1064nm) for range finding and designation uses. The wavelength of these lasers, operating in the near Infra-Red range (invisible), is also focused tightly on the retina. The human eye does not respond to the invisible light so there is no natural protection (eye blink reflex) as in the visible light. The operation of these lasers worldwide, especially when the laser beam is exposed, causes occasional eye accidents. Another risk is stemming from the use of observation systems with a high optical gain, in the laser operation areas, which enlarge the range of risk quite significantly. Therefore, research and development efforts were invested in order to introduce eye safe lasers. One of the solutions for this problem is presented in following document

  11. Eye casualty services in London

    Science.gov (United States)

    Smith, H B; Daniel, C S; Verma, S

    2013-01-01

    The combined pressures of the European Working Time Directive, 4 h waiting time target, and growing rates of unplanned hospital attendances have forced a major consolidation of eye casualty departments across the country, with the remaining units seeing a rapid increase in demand. We examine the effect of these changes on the provision of emergency eye care in Central London, and see what wider lessons can be learned. We surveyed the managers responsible for each of London's 8 out-of-hours eye casualty services, analysed data on attendance numbers, and conducted detailed interviews with lead clinicians. At London's two largest units, Moorfields Eye Hospital and the Western Eye Hospital, annual attendance numbers have been rising at 7.9% per year (to 76 034 patients in 2010/11) and 9.6% per year (to 31 128 patients in 2010/11), respectively. Using Moorfields as a case study, we discuss methods to increase capacity and efficiency in response to this demand, and also examine some of the unintended consequences of service consolidation including patients travelling long distances to geographically inappropriate units, and confusion over responsibility for out-of-hours inpatient cover. We describe a novel ‘referral pathway' developed to minimise unnecessary travelling and delay for patients, and propose a forum for the strategic planning of London's eye casualty services in the future.

    Conclusion: In a comparison of children of the same ages, hearing-impaired children have significantly more eye problems; therefore, a possible relation between deafness and eye problems must exist. Paying attention to eye health assessment in hearing-impaired children may help prevent adding eye problems to hearing difficulties.

  18. An improved likelihood model for eye tracking

    DEFF Research Database (Denmark)

    Hammoud, Riad I.; Hansen, Dan Witzner

    2007-01-01

    While existing eye detection and tracking algorithms can work reasonably well in a controlled environment, they tend to perform poorly under real world imaging conditions where the lighting produces shadows and the person's eyes can be occluded by e.g. glasses or makeup. As a result, pixel clusters...... associated with the eyes tend to be grouped together with background-features. This problem occurs both for eye detection and eye tracking. Problems that especially plague eye tracking include head movement, eye blinking and light changes, all of which can cause the eyes to suddenly disappear. The usual...... approach in such cases is to abandon the tracking routine and re-initialize eye detection. Of course this may be a difficult process due to missed data problem. Accordingly, what is needed is an efficient method of reliably tracking a person's eyes between successively produced video image frames, even...

  19. Twenty years of Hendra virus: laboratory submission trends and risk factors for infection in horses.

    Science.gov (United States)

    Smith, C S; McLAUGHLIN, A; Field, H E; Edson, D; Mayer, D; Ossedryver, S; Barrett, J; Waltisbuhl, D

    2016-11-01

    Hendra virus (HeV) was first described in 1994 in an outbreak of acute and highly lethal disease in horses and humans in Australia. Equine cases continue to be diagnosed periodically, yet the predisposing factors for infection remain unclear. We undertook an analysis of equine submissions tested for HeV by the Queensland government veterinary reference laboratory over a 20-year period to identify and investigate any patterns. We found a marked increase in testing from July 2008, primarily reflecting a broadening of the HeV clinical case definition. Peaks in submissions for testing, and visitations to the Government HeV website, were associated with reported equine incidents. Significantly differing between-year HeV detection rates in north and south Queensland suggest a fundamental difference in risk exposure between the two regions. The statistical association between HeV detection and stockhorse type may suggest that husbandry is a more important risk determinant than breed per se. The detection of HeV in horses with neither neurological nor respiratory signs poses a risk management challenge for attending veterinarians and laboratory staff, reinforcing animal health authority recommendations that appropriate risk management strategies be employed for all sick horses, and by anyone handling sick horses or associated biological samples.

  20. Confirmation of the presence of uveal effusion in Asian eyes with primary angle closure glaucoma: an ultrasound biomicroscopy study.

    2008-12-01

    To confirm the presence of uveal effusion in the eyes of Asian patients with primary angle closure glaucoma (PACG) using ultrasound biomicroscopy (UBM). In this observational case series, 70 patients with PACG (28 untreated patients with newly diagnosed PACG and 42 patients who had undergone previous laser iridotomy and were being monitored) and 12 patients with acute primary angle closure (APAC) were recruited. Eyes of patients with newly diagnosed PACG and APAC underwent UBM before and after laser iridotomy, whereas eyes of patients with treated PACG underwent UBM at enrollment. Uveal effusion was defined as a clear space between the choroid and sclera and was graded as follows: grade 0, none; grade 1, slitlike; grade 2, bandlike; and grade 3, obvious. Overall, uveal effusion was found in 11 of 70 eyes with PACG (15.7%; 95% confidence interval, 8.8%-26.2%) and in 3 of 12 eyes with APAC (25%; 95% confidence interval, 8.0%-53.4%). For patients with newly diagnosed PACG, uveal effusion was found in 4 of 28 eyes (14.2%; 95% confidence interval, 5.1%-32.1%) before laser iridotomy; 2 eyes had effusion after laser iridotomy. When present, the effusion was grade 1 in PACG eyes and grade 2 or 3 in APAC eyes. Uveal effusion was present in a significant proportion of Asian eyes with PACG and APAC, confirming a recent report of this finding.

  1. Acute corneal hydrops in keratoconus

    Directory of Open Access Journals (Sweden)

    Prafulla K Maharana

    2013-01-01

    Full Text Available Acute corneal hydrops is a condition characterized by stromal edema due to leakage of aqueous through a tear in descemet membrane. The patient presents with sudden onset decrease in vision, photophobia, and pain. Corneal thinning and ectasias combined with trivial trauma to the eye mostly by eye rubbing is considered as the underlying cause. With conservative approach self-resolution takes around 2 to 3 months. Surgical intervention is required in cases of non-resolution of corneal edema to avoid complications and for early visual rehabilitation. Intracameral injection of air or gas such as perflouropropane is the most common surgical procedure done. Recent investigative modality such as anterior segment optical coherence tomography is an extremely useful tool for diagnosis, surgical planning, and postoperative follow up. Resolution of hydrops may improve the contact lens tolerance and visual acuity but most cases require keratoplasty for visual rehabilitation.

    Full Text Available Helen M Rasmussen,1 Elizabeth J Johnson2 1Educational Studies, Lesley University, Cambridge, MA, USA; 2Carotenoid and Health Laboratory, Jean Mayer US Department of Agriculture Human Nutrition Research Center on Aging at Tufts University, Boston, MA, USA Abstract: The incidence of age-related eye diseases is expected to rise with the aging of the population. Oxidation and inflammation are implicated in the etiology of these diseases. There is evidence that dietary antioxidants and anti-inflammatories may provide benefit in decreasing the risk of age-related eye disease. Nutrients of interest are vitamins C and E, β-carotene, zinc, lutein, zeaxanthin, and the omega-3 fatty acids eicosapentaenoic acid and docosahexaenoic acid. While a recent survey finds that among the baby boomers (45–65 years old, vision is the most important of the five senses, well over half of those surveyed were not aware of the important nutrients that play a key role in eye health. This is evident from a national survey that finds that intake of these key nutrients from dietary sources is below the recommendations or guidelines. Therefore, it is important to educate this population and to create an awareness of the nutrients and foods of particular interest in the prevention of age-related eye disease.

    Since the launching of Global Initiative, VISION 2020 "the Right to Sight" many innovative, practical and unique comprehensive eye care services provision models have evolved targeting the underserved populations in different parts of the World. At places the rapid assessment of the burden of eye diseases in confined areas or utilizing the key informants for identification of eye diseases in the communities are promoted for better planning and evidence based advocacy for getting / allocation of resources for eye care. Similarly for detection and management of diabetes related blindness, retinopathy of prematurity and avoidable blindness at primary level, the major obstacles are confronted in reaching to them in a cost effective manner and then management of the identified patients accordingly. In this regard, the concept of tele-ophthalmology model sounds to be the best solution. Whereas other models on comprehensive eye care services provision have been emphasizing on surgical output through innovative scales of economy that generate income for the program and ensure its sustainability, while guaranteeing treatment of the poorest of the poor.

    Drug injection is an important technique in certain treatments of eye diseases. The efficacy of chemical mixing plays an important role in determining pharmacokinetics of injected drugs. In this study, we build a device to study the chemical mixing behavior in a spherical structure. The mixing process is visualized and analyzed qualitatively. We hope to understand the chemical convection and diffusion behaviors in correlation with controlled rapid mechanical movements. The results will have potential applications in treatment of eye diseases. Resnick Institute at Caltech.

    Full Text Available The impact of Yarbus's research on eye movements was enormous following the translation of his book Eye Movements and Vision into English in 1967. In stark contrast, the published material in English concerning his life is scant. We provide a brief biography of Yarbus and assess his impact on contemporary approaches to research on eye movements. While early interest in his work focused on his study of stabilised retinal images, more recently this has been replaced with interest in his work on the cognitive influences on scanning patterns. We extended his experiment on the effect of instructions on viewing a picture using a portrait of Yarbus rather than a painting. The results obtained broadly supported those found by Yarbus.

    2013-05-01

    We compared the choroidal thickness of the eyes of patients with acute primary angle-closure (APAC) with fellow eyes in the same patients. The analysis included 21 participants with unilateral APAC affected eyes and 21 fellow eyes with a diagnosis of primary angle-closure suspect (PACS). Enhanced depth imaging-optical coherence tomography (EDI-OCT) was used to measure the macular and peripapillary retinal and choroidal thickness in both eyes. The average choroidal thickness of the APAC eyes at each location or segment was compared to that of the fellow eyes. At all macular locations, the choroidal thickness was greatest at the subfovea for both groups. Comparison of the choroidal thickness between the groups showed that the thickness in the APAC eyes was significantly greater than in the PACS eyes at all locations except at 1 mm, 3 mm superior, 3 mm inferior, and 3 mm temporal from the fovea (P APAC eyes and 308.1 ± 70.5 μm in the PACS eyes, with a statistically significant difference (P APAC diagnosis and diastolic blood pressure and thinner in association with older subjects. APAC eyes have a higher level of macular choroidal thickness than PACS eyes when the IOP is reduced. However, the source of this difference is unclear and must be investigated further.

    The most important water-soluble components of the vertebrate eye (lens proteins, aqueous humor, vitreous, hyaluronic acid, ascorbic acid) have been investigated in aqueous solution, after preceding X- or UV-irradiation. Spectroscopic, chromatographic, electrophoretic, hydrodynamic and analytic techniques have been applied, to monitor several radiation damages such as destruction of aromatic and sulfur-containing amino acids, aggregation, crosslinking, dissociation, fragmentation, and partial unfolding. Various substances were found which were able to protect eye components effectively against radiation, some of them being also of medical relevance.

    2015-01-05

    A 64-year-old man presented with a 2-day history of acute onset painless left ptosis. He had no other symptoms; importantly pupils were equal and reactive and eye movements were full. There was no palpable mass or swelling. He was systemically well with no headache, other focal neurological signs, or symptoms of fatigue. CT imaging showed swelling of the levator palpebrae superioris suggestive of myositis. After showing no improvement over 5 days the patient started oral prednisolone 30 mg reducing over 12 weeks. The ptosis resolved quickly and the patient remains symptom free at 6 months follow-up. Acute ptosis may indicate serious pathology. Differential diagnoses include a posterior communicating artery aneurysm causing a partial or complete third nerve palsy, Horner's syndrome, and myasthenia gravis. A careful history and examination must be taken. Orbital myositis typically involves the extraocular muscles causing pain and diplopia. Isolated levator myositis is rare. 2015 BMJ Publishing Group Ltd.

  1. Distinct Biochemical Activities of Eyes absent During Drosophila Eye Development

    Science.gov (United States)

    Jin, Meng; Mardon, Graeme

    2016-01-01

    Eyes absent (Eya) is a highly conserved transcriptional coactivator and protein phosphatase that plays vital roles in multiple developmental processes from Drosophila to humans. Eya proteins contain a PST (Proline-Serine-Threonine)-rich transactivation domain, a threonine phosphatase motif (TPM), and a tyrosine protein phosphatase domain. Using a genomic rescue system, we find that the PST domain is essential for Eya activity and Dac expression, and the TPM is required for full Eya function. We also find that the threonine phosphatase activity plays only a minor role during Drosophila eye development and the primary function of the PST and TPM domains is transactivation that can be largely substituted by the heterologous activation domain VP16. Along with our previous results that the tyrosine phosphatase activity of Eya is dispensable for normal Eya function in eye formation, we demonstrate that a primary function of Eya during Drosophila eye development is as a transcriptional coactivator. Moreover, the PST/TPM and the threonine phosphatase activity are not required for in vitro interaction between retinal determination factors. Finally, this work is the first report of an Eya-Ey physical interaction. These findings are particularly important because they highlight the need for an in vivo approach that accurately dissects protein function. PMID:26980695

    2008-08-01

    The in situ mouse brain perfusion method for measuring blood-brain barrier permeability was adapted to assess transport of solutes at the blood-brain and blood-eye barriers. The procedure was checked with radiolabeled markers in oxygenated bicarbonate-buffered fluid infused for 30 to 120 sec via a carotid artery. Vascular flow estimated with diazepam was 2.2-fold lower in the eye than in the brain. The vascular volume and the integrity markers sucrose and inulin indicated that a perfusion flow rate of 2.5 mL/min preserved the physical integrity of these organs. However, the brain vasculature integrity was more sensitive to acute perfusion pressure than the eye vasculature. The functional capacities of blood barriers were assessed with D-glucose; its transport followed Michaelis-Menten kinetics with an apparent K(m) of 7.6 mmol/L and a V(max) of 23 micromol/sec per g in the brain, and a K(m) of 22.9 mmol/L and a V(max) of 40 micromol/sec per g in the eye. The transport of cholesterol to the brain and eye was significantly enhanced by adding the Abca1 inhibitor probucol, suggesting an Abca1-mediated efflux at the mouse brain and eye blood barriers. Thus in situ carotid perfusion is suitable for elucidating transport processes at the blood-brain and blood-eye barriers.

  15. Eye temperature and heart rate variability of calves disbudded with or without local anaesthetic.

    Stewart, M; Stafford, K J; Dowling, S K; Schaefer, A L; Webster, J R

    2008-03-18

    The possibility that pain can be detected from changes in eye temperature and heart rate variability (HRV) during disbudding was examined in thirty calves, randomly assigned to four treatments: 1) sham handling (control), 2) local anaesthetic (LA, cornual nerve injection) and sham disbudded, 3) sham LA and disbudded, 4) LA and disbudded. During a 40 min sampling period, maximum eye temperature, behavior and HRV parameters were recorded continuously. One week later, twelve disbudded calves were injected with adrenocorticotrophic hormone (ACTH) or saline and maximum eye temperature was recorded. There was a rapid drop in eye temperature during the 5 min following disbudding without LA (Ptemperature then increased and was higher than baseline over the remaining sampling period following both disbudding procedures (Ptemperature prior to disbudding (Ptemperature did not change following ACTH, suggesting that hypothalamus-pituitary-adrenal axis (HPA) activity is not responsible for the changes in eye temperature following disbudding. The increase in LF/HF ratio following disbudding without LA suggests an acute sympathetic response to pain, which could be responsible for the drop in eye temperature via vasoconstriction. HRV and eye temperature together may be a useful non-invasive and more immediate index of pain than HPA activity alone.

  19. Anticipatory Eye Movements in Congkak

    Directory of Open Access Journals (Sweden)

    Sheryl Chong

    2011-05-01

    Full Text Available Congkak is a traditional Malaysian board game involving two players taking turns to pick up marbles from a series of holes on the board. We used this game as a model to explore the role of anticipatory eye movements during natural actions (in this case serially picking up/putting marbles as novices learnt the game. Prior work on eye and hand movements in natural behaviour shows that much of the demand on the visual system is computed at the moment it is needed and doesn't depend on information acquired from previous fixations. Vision is driven by the task demands. However, anticipatory fixations to upcoming targets of manipulation have recently been shown to confer spatial accuracy and influence the eye-hand latency. We find that experience with the game also influences the deployment of these anticipatory “look-ahead” fixations, and that their influence on eye-hand latency varies with experience. Results suggest that as our experience in Congkak grows, so does our knowledge of the space relationships necessary for task success.

  5. Silence, an Eye of Knowledge

    Directory of Open Access Journals (Sweden)

    Mehdi Aghamohammadi

    2017-04-01

    Full Text Available One of the conspicuous features of the twentieth-century West was silence. This idea could be supported by examining reflections of Ludwig Wittgenstein, Fritz Mauthner, John Cage, Samuel Beckett, Ihab Hassan, Franz Kafka, Wassily Kandinsky, Jean-Paul Sartre, Virginia Woolf, Wolfgang Iser, Jacques Derrida, and Pierre Macherey. To me, silence is not a mere theory, but rather a phenomenon from which we can get practical benefits. I believe silence is an eye, eye of knowledge. We can broaden our knowledge of the world through silence. To convey the idea that silence is an eye, I have concocted the word slence, where  has replaced the letter i and stands for the eye. This means knowledge can enable us to see, thereby acquiring knowledge of, what used to be invisible, and accordingly unknowable. In other words, through silence, we can achieve a certain type of literacy. I substantiate this claim by exploring the Horus myth, Ojo de Dios, John Cage’s 4' 33", the nature of Expressionist paintings, Hinduism, thoughts of Hermes Trismegistus and Ibn al-Arabi, and practices of Mohammad, the prophet of Islam.

  7. Arthropods affecting the human eye.

    Science.gov (United States)

    Panadero-Fontán, Rosario; Otranto, Domenico

    2015-02-28

    Ocular infestations by arthropods consist in the parasitization of the human eye, either directly (e.g., some insect larvae causing ophthalmomyiasis) or via arthropods feeding on lachrymal/conjunctival secretions (e.g., some eye-seeking insects, which also act as vectors of eye pathogens). In addition, demodicosis and phthiriasis may also cause eye discomfort in humans. Ophthalmomyiasis by larvae of the families Oestridae, Calliphoridae and Sarcophagidae, are frequent causative agents of human ocular infestations. Over the last decades, the extensive use of macrocyclic lactones in cattle has reduced the frequency of infestations by Hypoderma bovis and Hypoderma lineatum (family Oestridae), and consequently, human infestations by these species. A prompt diagnosis of ocular myiasis (e.g., by serological tests) is pivotal for positive prognoses, particularly when the larvae are not detectable during the ophthalmologic examination. Molecular diagnoses may also assist physicians and parasitologists in achieving time-efficient diagnoses of infestations by Oestridae causing myiasis. Finally, due to widespread international travel to exotic destinations, cases of myiasis are increasing in non-endemic areas, therefore requiring physicians to acquire a profound knowledge of the clinical symptoms linked to these infestations to prevent costly, inappropriate treatments or severe complications.

    Full Text Available Corneal transplantation has been in routine practice to treat corneal endothelial diseases like Bullous Keratopathy, in which either the whole cornea or the partial cornea (the endothelium alone is transplanted from the cadaver donor to the recipient with the endothelial disease [1]. In whole corneal or partial corneal transplant one cadaver donor's cornea can be used to treat one recipient cornea only, which leads to a huge global shortage of donor corneas [2]. At this juncture Yokoo et al isolated and expanded corneal endothelial precursors using the sphere forming assay in vitro [3] and demonstrated the in vivo transplantation of these corneal endothelial precursors in a rabbit model of bullous keratopathy [4]. Following this, we studied the transportation of cadaver donor derived corneal endothelial tissue (CET from human cadaver donors in a thermoreversible gelation polymer (TGP (4 based transportation cocktail without cool preservation and demonstrated the viability of human corneal endothelial precursor (HCEP cells isolated from these CETs even after 72 hours of transportation without cool preservation [5]. This was done to suit the conditions existing in developing nations like India where hospitals might be located far from eye banks and maintaining cold chain preservation is relatively difficult. Further, these HCEPs were expanded in vitro using a polymer based expansion protocol [5]. This was the first step in the realisation of the dream of 'Eye for eyes' in a manner suitable for Indian conditions.

  13. Dominant-submissive behavior as models of mania and depression.

    Malatynska, Ewa; Knapp, Richard J

    2005-01-01

    This review examines the ways in which dominant-subordinate behavior in animals, as determined in laboratory studies, can be used to model depression and mania in humans. Affective disorders are mood illnesses with two opposite poles, melancholia (depression) and mania that are expressed to different degrees in affected individuals. Dominance and submissiveness are also two contrasting behavioral poles distributed as a continuum along an axis with less or more dominant or submissive animals. The premise of this article is that important elements of both mania and depression can be modeled in rats and mice based on observation of dominant and submissive behavior exhibited under well defined conditions. Studies from our own research, where dominance and submissiveness are defined in a competition test and measured as the relative success of two food-restricted rats to gain access to a feeder, have yielded a paradigm that we call the Dominant Submissive Relationship (DSR). This paradigm results in two models sensitive to drugs used to treat mood disorders. Specifically, drugs used to treat mania inhibit the dominant behavior of rats gaining access to food at the expense of an opponent (Reduction of Dominant Behavior Model or RDBM), whereas antidepressants counteract the behavior of rats losing such encounters; Reduction of Submissive Behavior Model (RSBM). The validation of these models, as well as their advantages and limitations, are discussed and compared with other animal paradigms that utilize animal social behavior to model human mood disturbances.

  17. Depth-estimation-enabled compound eyes

    Science.gov (United States)

    Lee, Woong-Bi; Lee, Heung-No

    2018-04-01

    Most animals that have compound eyes determine object distances by using monocular cues, especially motion parallax. In artificial compound eye imaging systems inspired by natural compound eyes, object depths are typically estimated by measuring optic flow; however, this requires mechanical movement of the compound eyes or additional acquisition time. In this paper, we propose a method for estimating object depths in a monocular compound eye imaging system based on the computational compound eye (COMPU-EYE) framework. In the COMPU-EYE system, acceptance angles are considerably larger than interommatidial angles, causing overlap between the ommatidial receptive fields. In the proposed depth estimation technique, the disparities between these receptive fields are used to determine object distances. We demonstrate that the proposed depth estimation technique can estimate the distances of multiple objects.

  18. EVALUATION OF DRY EYES IN DIABETES MELLITUS

    2017-12-01

    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.

  8. Trustworthy-looking face meets brown eyes.

    Directory of Open Access Journals (Sweden)

    Karel Kleisner

    Full Text Available We tested whether eye color influences perception of trustworthiness. Facial photographs of 40 female and 40 male students were rated for perceived trustworthiness. Eye color had a significant effect, the brown-eyed faces being perceived as more trustworthy than the blue-eyed ones. Geometric morphometrics, however, revealed significant correlations between eye color and face shape. Thus, face shape likewise had a significant effect on perceived trustworthiness but only for male faces, the effect for female faces not being significant. To determine whether perception of trustworthiness was being influenced primarily by eye color or by face shape, we recolored the eyes on the same male facial photos and repeated the test procedure. Eye color now had no effect on perceived trustworthiness. We concluded that although the brown-eyed faces were perceived as more trustworthy than the blue-eyed ones, it was not brown eye color per se that caused the stronger perception of trustworthiness but rather the facial features associated with brown eyes.

    We investigated eye movement during past and future thinking. Participants were invited to retrieve past events and to imagine future events while their scan path was recorded by an eye-tracker. Past thinking triggered more fixation (p thinking. Past and future thinking triggered a similar duration of fixations and saccades, as well as a similar amplitude of saccades. Interestingly, participants rated past thinking as more vivid than future thinking (p thinking seems to be accompanied by an increased number of fixations and saccades. Fixations and saccades in past thinking can be interpreted as an attempt by the visual system to find (through saccades) and activate (through fixations) stored memory representations. The same interpretation can be applied to future thinking as this ability requires activation of past experiences. However, future thinking triggers fewer fixations and saccades than past thinking: this may be due to its decreased demand on visual imagery, but could also be related to a potentially deleterious effect of eye movements on spatial imagery required for future thinking.

    Full Text Available Masahiko Ayaki, Motoko Kawashima, Kazuno Negishi, Kazuo Tsubota Department of Ophthalmology, Keio University School of Medicine, Tokyo, JapanPurpose: We aimed to explore the prevalence of probable sleep and mood disorders in eye clinic visitors.Methods: This was a cross-sectional study. The participants were outpatients at six eye clinics from January through March, 2014. Outpatients were invited to complete a questionnaire containing the Pittsburgh Sleep Quality Index (PSQI and Hospital Anxiety and Depression Scale (HADS. A final diagnosis was made, and patients were classified into six diagnostic groups. The main outcome measures were the scores of the PSQI and HADS among the diagnostic groups. Results: A total 1,000 outpatients participated, and 730 patients (mean age 59.5±19.0 years; 487 females were analyzed after exclusion of children and patients diagnosed with healthy eyes, acute injury, or unilateral pseudophakia. The mean PSQI and HADS scores across all patients were 5.3±3.1 and 9.2±6.2, respectively. For the diagnostic groups, the mean PSQI and HADS scores, respectively, were 5.7±3.3 and 10.2±6.0 for dry eye (n=247, 5.4±3.2 and 9.2±5.7 for bilateral cataracts (n=159, 5.3±3.3 and 8.0±5.3 for bilateral pseudophakia (n=99, and, 5.0±3.1 and 9.8±6.6 for glaucoma (n=109. Overall, 37.3% of patients were poor sleepers (PSQI ≥6, and 45.5% had possible mood disorders (HADS ≥10. Stepwise regression analysis revealed that the PSQI and HADS scores were significantly correlated with both age (P<0.05 and the presence of dry eye (P<0.05. Conclusion: The prevalence of sleep and mood disorders was significantly higher in patients with dry eye. The present results suggest consultation-liaison psychiatry services may be beneficial among eye disease patients.Keywords: depression, anxiety, cataract, liaison psychiatry, glaucoma

    International Nuclear Information System (INIS)

    Bartalena, Luigi; Tanda, Maria Laura; Marcocci, Claudio; Pinchera, Aldo

    2002-01-01

    Thyroid eye disease (TED) is the most frequent extrathyroidal manifestation of Graves' disease. In most instances it is mild and non-progressive, but in 3%-5% of cases it is severe. Non-severe TED requires only supportive measures, such as eye ointments, sunglasses and prisms. By contrast, severe TED requires aggressive treatment, either medical (high-dose glucocorticoids, orbital radiotherapy) or surgical (orbital decompression). The choice of treatment relies on the assessment of both TED severity and activity. Removal of controllable risk factors, especially cigarette smoking, is important to improve the course and the therapeutic outcome. A coordinated approach to the treatment of hyperthyroidism and TED is also required. Novel promising treatments, to be verified in large series of patients, include somatostatin analogues and cytokine antagonists. (orig.)

    The purpose of this study was to assess the inflammatory status of the aqueous humor in the fellow eye after uneventful cataract surgery in the first eye. At the screening stage, aqueous humor samples from 15 first-eye and 15 second-eye cataract patients were collected just before cataract surgery and assayed using human cytokine antibody array. Screened cytokines were then verified using a suspension array system with aqueous humor samples obtained from 35 first-eye and 36 second-eye cataract patients. The cytokine antibody array revealed that interleukin-1 receptor antagonist (Il-1ra) and macrophage inflammatory protein (MIP)-1a and MIP-1b were expressed at high levels in first-eye patients and were lower in second-eye patients, whereas opposite trends were found for monocyte chemoattractant protein 1 (MCP-1) and for regulated on activation, normal T expressed and secreted (RANTES) (all, P eye patients than in that of first-eye patients (P = 0.0067, Student's t-test). This study revealed that expression of MCP-1, a pain-related inflammatory chemokine, was significantly increased in aqueous humor in the contralateral eye after first-eye cataract surgery. This suggests there may be a sympathetic ophthalmic type uveitis in the contralateral eye after first-eye cataract surgery and that may help to explain why second-eye phacoemulsification is often more painful.
