    BACKGROUND: Juvenile nasopharyngeal angiofibroma is a benign, vascular tumour that primarily occurs in adolescent males. Despite its benign nature, aggressive growth patterns can cause potential life-threatening complications. Juvenile nasopharyngeal angiofibroma is normally unilateral, originating...... from the sphenopalatine artery, but bilateral symptoms can occur if a large tumour extends to the contralateral side of the nasopharynx. This paper presents the first reported case of true bilateral extensive juvenile nasopharyngeal angiofibroma involving clinically challenging pre-surgical planning...... embolisation. Radical removal performed as one-step, computer-assisted functional endoscopic sinus surgery was performed. The follow-up period was uncomplicated. CONCLUSION: This case illustrates the importance of suspecting bilateral juvenile nasopharyngeal angiofibroma in patients presenting with bilateral...

    Full Text Available To present a rare complication, such as bilateral cataracts, in a man who sustained a high-voltage electrical injury. A 35- year-old man was admitted with a complaint of decrease in visual acuity. He had a history of a contact with a power line carrying 30.000 volts of electricity while working at a construction site. Examination at a burn center revealed second-degree facial, neck and left foot burns. One month later, the patient underwent amputation of fourth and fifth toes of his left foot. During the next 6 months, he noted decreasing vision in both eyes. Ocular examination 1 year after the accident revealed that the patient’s visual acuity had deteriorated to 1/10 in both eyes. The cornea on the left eye showed superficial punctate opacities. The lenses in both eyes had anterior subcapsular cortical lens opacities and posterior subcapsular opacities. Uncomplicated bilateral phacoemulsification surgery with intraocular lens implantation was performed and the patient’s visual acuity returned to 10/10 in both eyes. We noted that the fundus remained normal in both eyes. Electrical cataracts are still a serious potential complication that may occur after electrical injury. Awareness of this by burn team members is important for providing optimal treatment to those who have suffered an electrical injury. (Turk J Ophthalmol 2011; 41: 197-9

    To present an economic-analysis comparison of simultaneous and sequential bilateral cataract surgery. Helsinki University Eye Hospital, Helsinki, Finland. Economic analysis. Effects were estimated from data in a study in which patients were randomized to have bilateral cataract surgery on the same day (study group) or sequentially (control group). The main clinical outcomes were corrected distance visual acuity, refraction, complications, Visual Function Index-7 (VF-7) scores, and patient-rated satisfaction with vision. Health-care costs of surgeries and preoperative and postoperative visits were estimated, including the cost of staff, equipment, material, floor space, overhead, and complications. The data were obtained from staff measurements, questionnaires, internal hospital records, and accountancy. Non-health-care costs of travel, home care, and time were estimated based on questionnaires from a random subset of patients. The main economic outcome measures were cost per VF-7 score unit change and cost per patient in simultaneous versus sequential surgery. The study comprised 520 patients (241 patients included non-health-care and time cost analyses). Surgical outcomes and patient satisfaction were similar in both groups. Simultaneous cataract surgery saved 449 Euros (€) per patient in health-care costs and €739 when travel and paid home-care costs were included. The savings added up to €849 per patient when the cost of lost working time was included. Compared with sequential bilateral cataract surgery, simultaneous bilateral cataract surgery provided comparable clinical outcomes with substantial savings in health-care and non-health-care-related costs.

    2007-01-01

    Background Dense congenital cataracts often cause severe visual impairment. The results of long-term follow-up of dense bilateral congenital cataract in China have not been well documented. The purpose of this study was to evaluate the long-term visual function in children who underwent cataract extraction for dense bilateral congenital cataract in southern part of China.Methods Medical records of children who underwent surgery of dense bilateral congenital cataract between January 1992 and December 2000 at Zhongshan Ophthalmic Center of Sun Yat-sen University were retroactively reviewed. In 38 children available for current follow-up, best corrected visual acuity (BCVA) and stereoscopic vision, as well as nystagmus, strabismus, and other complications, were evaluated. The mean follow-up period was 107.6 months (range 60 to 167 months).Results The mean age of cataract extraction and secondary intraocular lens implantation were 5.6 months (range 3 to 12 months) and 4.2 years (range 2.4 to 15 years), respectively. The mean BCVA was 0.25 in the better eye and 0.16 in the fellow eye. Stereoscopic vision was absent in all patients, and 3 children had simultaneous perception. Nystagmus was detected in all cases and strabismus in 35 cases. A high correlation was found between timing of cataract extraction and final BCVA of the better eye (r=-0.55, P=0.00). A statistically significant difference was found in BCVA between postand pre-treatment of amblyopia (t=5.65, P=0.00).Conclusions Long-term visual function in children with dense bilateral congenital cataract was poor when cataract surgery was performed at age of 3 months or later. Earlier cataract surgery with adequate optical rehabilitation contributed to better visual outcome.

  8. Pros and cons of immediately sequential bilateral cataract surgery (ISBCS).

    Grzybowski, Andrzej; Wasinska-Borowiec, Weronika; Claoué, Charles

    2016-01-01

    Immediately sequential bilateral cataract surgery (ISBCS) is currently a "hot topic" in ophthalmology. There are well-documented advantages in terms of quicker visual rehabilitation and reduced costs. The risk of bilateral simultaneous endophthalmitis and bilateral blindness is now recognized to be minuscule with the advent of intracameral antibiotics and modern management of endophthalmitis. Refractive surprises are rare for normal eyes and with the use of optical biometry. Where a general anesthetic is indicated for cataract surgery, the risk of death from a second anesthetic is much higher than the risk of blindness. A widely recognized protocol from the International Society of Bilateral Cataract Surgeons needs to be adhered to if surgeons wish to start practicing ISBCS.

    Full Text Available Abstract Introduction Hepatologists and internists often encounter patients with unexplained high serum ferritin concentration. After exclusion of hereditary hemochromatosis and hemosiderosis, rare disorders like hereditary hyperferritinemia cataract syndrome should be considered in the differential diagnosis. This autosomal dominant syndrome, that typically presents with juvenile bilateral cataracts, was first described in 1995 and has an increasing number of recognized molecular defects within a regulatory region of the L-ferritin gene (FTL. Case presentation Two patients (32 and 49-year-old Caucasian men from our ambulatory clinic were suspected as having this syndrome and a genetic analysis was performed. In both patients, sequencing of the FTL 5' region showed previously described mutations within the iron responsive element (FTL c.33 C > A and FTL c.32G > C. Conclusion Hereditary hyperferritinemia cataract syndrome should be considered in all patients with unexplained hyperferritinemia without signs of iron overload, particularly those with juvenile bilateral cataracts. Liver biopsy and phlebotomy should be avoided in this disorder.

    Full Text Available Craniofacial microsomia (CFM includes a spectrum of malformations primarily involving structures derived from the first and second branchial arches. Patients with hemifacial microsomia and epibulbar dermoids are said to have Goldenhar syndrome (GHS. Four-month-old boy with whitish pupillary reflex presented with the features of GHS in pediatric ophthalmology clinic. The child had ocular and auricular manifestations. There were no vertebral anomalies, but he had bilateral congenital cataract. The peculiarity of this case is the presence of the bilateral total congenital cataract, in association with CFM. There is absence of epibulbar dermoid or lipodermoid in the eyes, although the child had features of GHS. In addition to it, anesthetic intubation was smooth in this case. Any case diagnosed with CFM and/or GHS needs treatment through multidisciplinary approach, consultation in ophthalmology department is one of them.

    Full Text Available Objectives: The aim of this study was to evaluate the safety and visual outcomes of simultaneous bilateral cataract surgery (SBCS with intraocular lens implantation performed in outreach surgical eye camps. Methods: The medical records of 47 consecutive patients who underwent simultaneous bilateral small-incision cataract surgery between January 2010 and December 2015 in outreach surgical camps in rural Cameroon were reviewed. The measures included postoperative visual outcomes and intraoperative and postoperative complications. Results: Data from 94 eyes of 47 participants (30 men, 17 women; mean age: 60.93 ± 13.58 years, range: 45-80 years were included in this study. The presented best visual acuity (VA was less than 3/60 in 100% of the eyes. At the 4-week follow-up, 84.04% of the eyes showed increased VA of 1 line or more ( P  = .001.Of these, 71 (75.53% achieved good VA (greater than 6/18. Intraoperative or postoperative complications occurred in 19 (20.21% eyes. The most serious intraoperative complication was a posterior capsule rupture and vitreous loss (2 patients, 2 eyes. The postoperative complications included a transient elevation in the intraocular pressure (6 eyes, chronic corneal oedema (5 eyes, iris capture (3 eyes, lens decentration (2 eyes, and hyphema (1 eye. No cases of postoperative endophthalmitis were recorded. Conclusions: Under the strict observation of endophthalmitis prophylaxis, SBCS is an option to reduce the cataract blindness backlog in rural areas of developing countries.

    An 8-year-old girl presented with bilateral breast masses and was subsequently diagnosed with juvenile myelomonocytic leukemia. Juvenile myelomonocytic leukemia is a rare myelodysplastic syndrome that typically presents in boys younger than 3 years of age with splenomegaly, lymphadenopathy and skin findings. Bilateral breast masses in a child are rare and, as such, present a diagnostic dilemma due to the relative paucity of cases in the literature. We present a case of granulocytic sarcoma of the breasts in a patient with juvenile myelomonocytic leukemia. The authors hope that increased reporting and research regarding pediatric breast masses will help create awareness for such cases. (orig.)

    Congenital cataract is one of the most treatable causes of visual impairment and blindness during infancy, with an estimated prevalence of approximately 2.5:10,000 infants under the age of 1 year. Congenital cataract can be observed with certain chromosomal abnormalities, such as trisomies, deletions, translocations and Turner syndrome. In Klinefelter syndrome, however, ocular complications and cataract are not commonly encountered, so reports in the literature are very rare. In this manuscript, we present a 3-month-old male infant who had congenital cataracts. Chromosomal analysis revealed that his karyotype was 47,XXY. He did not show any of the main clinical signs of Klinefelter syndrome because of his very young age. To the best of our knowledge, our patient is only the second-ever case reported in the literature in which congenital cataracts have been found in an infant with a nonmosaic 47,XXY karyotype. The aim of the present report is to both describe the ocular abnormalities that can sometimes be found in Klinefelter syndrome and to emphasize the importance of performing a karyotype analysis in order to rule out chromosome abnormalities in patients with congenital cataracts.

    Experience with the removal of complicated cataract by lensectomy in patients with juvenile chronic iridocyclitis (JCI) has so far been limited. The results of lensectomy were reviewed retrospectively in 131 patients with JCI (187 eyes). The mean follow up period was 5 years 4 months. The main operative complication was accidental loss of lens material into the vitreous cavity. The postoperative complications were glaucoma (23 eyes, 15%), phthisis (14 eyes, 8%), secondary pupillary membranes (11 eyes, 6%), and retinal detachment (six eyes, 3%). The incidence of postoperative phthisis was related to the level of intraocular pressure (IOP) at the time of surgery. Twenty four per cent of hypotonous eyes and 4% of eyes with normal or elevated IOP became phthisical. Visual acuity was improved in 77%, was worse in 13%, and unchanged in 10% of eyes. The main causes of a postoperative visual acuity of 6/60 or less were glaucoma, amblyopia, and phthisis. Lensectomy did not appear to alter the course of uveitis.

    2014-06-01

    Full Text Available BACKGROUND: Congenital rubella syndrome (CRS is the second leading cause of non‐ traumatic childhood cataracts in India. While nuclear cataract is the most common abnormality reported in CRS, congenital glaucoma is a rarer manifestation. CASE REPORT: A 34weeks low birth weight, male neonate was born by vaginal delivery with normal APGARS. The neonate had sparse hypo pigmented hair over the scalp, along with hypopigmented eye brows and eye lashes. There were erythematous lesions over palms, soles and groin region. Eye examination revealed bilateral nuclear cataracts along with buphthalmos. The neonate also had clinical manifestations of PDA, which was confirmed by 2-D Echo. Systemic involvement was seen as hepatosplenomegaly and bilateral cryptorchidism. Hence CRS was suspected and further evaluation was done. There was thrombocytopenia, mild unconjugated hyperbilirubinemia with elevated transaminases. Neurosonogram was normal and there were no intra cranial calcifications. TORCH profile in both mother and baby showed elevated rubella IgM levels confirming CRS. The neonate received supportive and symptomatic treatment. DISCUSSION: congenital nuclear cataracts are reported in 60-80% of CRS, while buphthalmos is rarely seen, more so in neonatal period. PDA occurs in 50% of CRS and two-thirds have hepatosplenomegaly. Rubelliform rash is infrequent in neonates with CRS. CONCLUSION: We report a preterm low birth weight, male neonate with congenital rubella syndrome and its rare manifestations

    2015-01-01

    Full Text Available The aim of the present systematic review was to examine the benefits and harms associated with immediate sequential bilateral cataract surgery (ISBCS with specific emphasis on the rate of complications, postoperative anisometropia, and subjective visual function in order to formulate evidence-based national Danish guidelines for cataract surgery. A systematic literature review in PubMed, Embase, and Cochrane central databases identified three randomized controlled trials that compared outcome in patients randomized to ISBCS or bilateral cataract surgery on two different dates. Meta-analyses were performed using the Cochrane Review Manager software. The quality of the evidence was assessed using the GRADE method (Grading of Recommendation, Assessment, Development, and Evaluation. We did not find any difference in the risk of complications or visual outcome in patients randomized to ISBCS or surgery on two different dates. The quality of evidence was rated as low to very low. None of the studies reported the prevalence of postoperative anisometropia. In conclusion, we cannot provide evidence-based recommendations on the use of ISBCS due to the lack of high quality evidence. Therefore, the decision to perform ISBCS should be taken after careful discussion between the surgeon and the patient.

  7. Bilateral periprosthetic stress fractures in a juvenile chronic arthritis patient secondary to bilateral genu valgum.

    Al-Khateeb, H; Meir, A; Singer, G C

    2007-01-01

    Lateral insufficiency fractures following total hip replacement have been reported with the femoral stems positioned in varus, together with osteopenia of the lateral femoral cortex. Any abnormal alignment of the lower limbs, such as genu valgum, will alter the load distribution across the femoral cortices, and repetitive loading during walking will predispose the bones to stress fractures at any stress riser point, such as the tip of a femoral component. Bilateral femoral stress fractures post total hip replacements have not been previously described. We present a 55-year-old woman, diagnosed with juvenile idiopathic arthritis, who had undergone bilateral total hip replacements and bilateral knee replacements. The knees 15 years postoperatively were in valgus and the left knee was extremely stiff, flexing to just 5. The patient presented with bilateral thigh pain, with plain radiographs confirming bilateral periprosthetic fractures of the femur at the tip of well-fixed femoral components. There was no history of injury and her hips were functioning well up to this time. The patient required revision of both hips to long-stem uncemented components, bypassing the fractures, and revision of both knees to stemmed semi-constrained implants, thereby correcting the alignment of both lower limbs. Both fractures healed and the patient is currently pain-free and mobile with walking aids. Surgeons must remain aware that when implants are in situ, abnormal alignments will lead to abnormal forces, and stress fractures are likely to occur at any stress riser around the implant. Avoiding malalignment will avoid this complication.

    The aim of the study was to determine the average axial length reading of the bilateral pediatric cataract undergoing cataract surgery. Pre-operative axial length measurement was done in 80 children below 15 years who had bilateral pediatric cataract. Axial length measurement was done in 56 fellow eyes. The axial length was measured under general anesthesia with the Accutome A-scan. The mean age was 69.7 months (SD=52.6), range from one month to 168 months. The mean axial length reading was 21.3 mm in operated eyes and 21.1 mm in fellow eyes. The range of axial length reading was 16.2 -31.5 mm in operated eyes and it was 16.5 -31.5 mm in fellow eyes. This short observation found that in bilateral pediatric cataract, the axial length value is similar in both operated and fellow eyes. Based on the axial length value of the operated eye, the patients with bilateral congenital cataract can undergo surgery in those eye hospitals where facilities of measurement of axial length is not available.

    Full Text Available Context: Bilateral pediatric cataracts are important cause of visual impairment in children. Aim: To study the outcome of bilateral pediatric cataract surgery in young children. Setting and Design: Retrospective case series in a tertiary center. Materials and Methods: Records of pediatric cataracts operated between January 2001 and December 2003, with a minimum follow-up of 3 months, were reviewed retrospectively. Statistical Methods: Independent sample t-test, Fisher′s exact test, and logistic regression using SPSS (Statistical Package for Social Science, Chicago, USA version 12. Results: 215/257 (83.7% patients had a minimum follow-up of 3 months. The mean age of presentation to the hospital was 53 months (range: 0-168 months. Congenital cataract was present in 107 patients (58.2% and developmental cataract in 77 patients (41.8%. The mean age at surgery was 55.2 months (range: 1-168 months. Out of 430 eyes, 269 (62.6% had an intraocular lens implanted. The mean duration of follow-up was 13.1 months (range: 3-38 months. Pre-operatively, 102 patients (47.3% had visual acuity 6/18. The most common early post-operative complication was fibrinous uveitis in 57 eyes (13.3% and the most common delayed post-operative complication was posterior capsular opacification in 118 eyes (27.4%. The most important prognostic factor for poor outcome was congenital cataract (odds ratio [OR]: 26.3; 95% confidence interval [CI], 4.4-158.5 and total cataract (OR: 4.8; 95% CI, 1.3-17. Conclusion: Nearly half of the eyes had visual acuity >6/18. The outcome was poorer in congenital cataracts, especially those operated after >1 year of age.

    To evaluate the predictability of refraction following immediate sequential bilateral cataract surgery (ISBCS) performed under general anaesthesia. This is a retrospective review of all ISBCS performed at Kantonsspital Winterthur, Switzerland, between April 2000 and September 2013. The case notes of 250 patients were reviewed. Patients having full refraction reported (110 patients/220 eyes) were included. 210 (95 %) eyes had a straight forward phacoemulsification with posterior chamber intraocular lens implantation, seven eyes had a planned extracapsular cataract extraction (ECCE); three eyes had an intracapsular cataract extraction. Both eyes of 110 patients (64 women, 46 men) with a mean age of 79.0 years, standard deviation (SD) ±11.4 (range 26 to 97 years) were included. Median preoperative best corrected visual acuity (BCVA) was 0.5 LogMAR in the first eye, the interquartile range (IQR) was [0.4, 1.2]; 0.7 LogMAR in the second eye with IQR [0.4, 1.8]. At one month, the median BCVA was 0.2 LogMAR, IQR [0.1, 0.3] in the first eye, median BCVA was 0.1 LogMAR and IQR [0.0, 0.5] in the second eye. There were 3 eyes (3 %) that lost 3 lines or more in BCVA at one month (control vs. pre-operatively). In all three cases, poor visual acuity had been recorded pre-operatively (>1 LogMAR). Achieved refraction was within ±1.0 D of the target in 83 % of eyes. There were only 5 % (n = 6) of cases where if delayed sequential bilateral extraction had been performed could potentially intraocular lens (IOL) choice have been adjusted, in four of these cases, target refraction was within ±1.0 D in the second eye. ISBCS performed under general anaesthesia achieves target refraction in 83 % of eyes after consideration of complications, ocular co-morbidities and systemic restrictions. In the majority of cases where IOL power calculation could be considered, the achieved refraction of the second surgical eye was within ±1.0 D of intended refraction. This undermines the

    Full Text Available Aims: To compare the corneal refractive changes induced after 3.0 mm temporal and nasal corneal incisions in bilateral cataract surgery. Materials and Methods: This prospective study comprised a consecutive case series of 60 eyes from 30 patients with bilateral phacoemulsification that were implanted with a 6.0 mm foldable intraocular lens through a 3.0 mm horizontal clear corneal incision (temporal in the right eyes, nasal in the left eyes. The outcome measures were surgically induced astigmatism (SIA and uncorrected visual acuity (UCVA 1 and 3 months, post-operatively. Results: At 1 month, the mean SIA was 0.81 diopter (D for the temporal incisions and 0.92 D for nasal incisions (P = 0.139. At 3 months, the mean SIA were 0.53 D for temporal incisions and 0.62 D for nasal incisions (P = 0.309. The UCVA was similar in the 2 incision groups before surgery, and at 1 and 3 months post-operatively. Conclusion: After bilateral cataract surgery using 3.0 mm temporal and nasal horizontal corneal incisions, the induced corneal astigmatic change was similar in both incision groups. Especially in Asian eyes, both temporal and nasal incisions (3.0 mm or less would be favorable for astigmatism-neutral cataract surgery.

    Juvenile giant fibroadenoma is a very rare breast disease affecting young girls of premenarche and adolescent ages. It is a benign fibroepithelial tumour characterised by stromal and epithelial proliferation that causes rapidly growing breast mass. Bilateral symmetrical involvement is extremely rare. In this article, we describe this entity in a girl aged 13 years who presented with bilateral gigantically enlarged breasts. Ultrasonography and MRI showed large, multilobulated masses involving both breasts entirely. Endovascular embolisation of bilateral internal mammary arteries and lateral thoracic arteries supplying the masses was performed prior to surgery to reduce their vascularity. The patient subsequently underwent excision of bilateral breast masses and reduction mammoplasty. Histopathologically, bilateral breast masses were confirmed to be juvenile fibroadenomas.

    Full Text Available Immediately sequential bilateral cataract surgery (ISBCS, the cataract surgery that is performed in both eyes simultaneously, is gaining popularity worldwide compared to the traditional treatment paradigm: delayed sequential bilateral cataract surgery (DSBCS, the surgery that is performed in each eye on a different day as a completely separate operation. ISBCS provides advantages to patients and patients' families in the form of fewer hospital visits. Additionally, patients enjoy rapid rehabilitation, lack of anisometropia - potentially reducing accidents and falls, and avoid suboptimal visual function in daily life. The hospital may benefit due to lower cost.To perform a systematic review and meta-analysis to evaluate ISBCS and DSBCS.Databases including MEDLINE, EMBASE, BIOSIS, CINAHL, Health Economic Evaluations Database (HEED, ISI Web of Science (Thomson-Reuters and the Cochrane Library were searched.Not applicable.Literature was systematically reviewed using EPPI-Reviewer 4 gateway. Meta-analysis was conducted using STATA v. 13.0. Standardized mean difference (SMD and 95% confidence intervals (CI were calculated and heterogeneity was assessed using I2 statistics. Fixed-effect and random-effect models were computed based on heterogeneity. Meta-analysis was done by instrument used to calculate utility score.In total, 9,133 records were retrieved from multiple databases and an additional 128 records were identified through grey literature search. Eleven articles with 3,657 subjects were included for analysis. Our meta-analysis results indicated significant improvement in post-operative utility score using TTO, EQ5D, HUI3, VF-7, and VF-14 and a non-significant improvement using Catquest questionnaire for both surgeries. For ISBCS versus DSBCS, utility-specific fixed-effect model provided an overall SMD of the utility score using the TTO method as 0.12 (95% CI: -0.15, 0.40, EQ5D as 0.14 (95% CI: -0.14, 0.41, HUI3 as 0.12 (95% CI: -0.15, 0.40, VF

    The finding of bilateral congenital cataracts in the fetus is rare. We report bilateral congenital cataracts detected during the routine second trimester anomaly scan, which subsequently were found to be associated with other congenital anomalies and the parents opted for a termination of pregnancy. At post-mortem, Muscle-Eye Brain disease or Walker-Warburg Syndrome was considered likely, which are autosomal recessive congenital muscular dystrophy disorders associated with cerebral, cerebellar, muscle and eye anomalies. On ultrasound, bilateral cataracts appear as echogenic, solid areas within the fetal orbits. The examination of the fetal face and orbits plays an important role in confirming fetal well-being antenatally. We propose that it should become a routine part of the structural survey of fetal anatomy during the obstetric anomaly scan. This is especially important in pregnancies previously affected by fetal cataracts or pregnancies at risk of rare genetic syndromes.

    Genome-wide linkage analysis, followed by targeted deep sequencing, in a Danish multigeneration family with juvenile cataract revealed a region of chromosome 17 co-segregating with the disease trait. Affected individuals were heterozygous for two potentially protein-disrupting alleles in this region, in ACACA and UNC45B. As alterations of the UNC45B protein have been shown to affect eye development in model organisms, effort was focused on the heterozygous UNC45B missense mutation. UNC45B encodes a myosin-specific chaperone that, together with the general heat shock protein HSP90, is involved in myosin assembly. The mutation changes p.Arg805 to Trp in the UCS domain, an amino acid that is highly conserved from yeast to human. UNC45B is strongly expressed in the heart and skeletal muscle tissue, but here we show expression in human embryo eye and zebrafish lens. The zebrafish mutant steif, carrying an unc45b nonsense mutation, has smaller eyes than wild-type embryos and shows accumulation of nuclei in the lens. Injection of RNA encoding the human wild-type UNC45B protein into the steif homozygous embryo reduced the nuclei accumulation and injection of human mutant UNC45B cDNA in wild-type embryos resulted in development of a phenotype similar to the steif mutant. The p.Arg805Trp alteration in the mammalian UNC45B gene suggests that developmental cataract may be caused by a defect in non-muscle myosin assembly during maturation of the lens fiber cells.

    About 20% of patients with juvenile chronic arthritis develop uveitis which is frequently bilateral. Risk factors for uveitis are: female gender, pauciarticular onset of arthritis, presence of circulating antinuclear antibodies, and the antigens HLA-DW5 and HLA-DPw2. The visual prognosis in patients with uveitis is good in 25% and fair in 50%. The remaining 25% develop cataract and/or glaucoma. The management of glaucoma is unsatisfactory, but the results of cataract surgery by lensectomy are good.

    The congenital cataract has been a clinically important cause of impaired vision development, making up about 10% of the cases of childhood blindness. Mutations of more than 40 genes have been identified causing congenital cataract with Mendelian inheritance, which indicated that it has an extremely high genetic heterogeneity. In this study, we recruited a large congenital cataract family and identified a missense mutation (c.143A>G: p.E48G) within gap junction protein alpha-3 (GJA3) gene in the proband using whole exome sequencing. Subsequent Sanger sequencing of this mutation in all family members revealed that this mutation cosegregated with the phenotype in the family with full penetrance. Our study identified a mutation in GJA3 that correlated with congenital cataract phenotype, which was not reported previously, and would be of benefit to the diagnosis of this genetic disorder. This finding expands the mutation spectrum of GJA3 and provides useful information for further study of the molecular pathogenesis of congenital cataract.

    2016-07-01

    Primary hyperparathyroidism is a generalized disorder of bone and mineral metabolism caused by autonomous secretion of parathyroid hormone. It is primarily seen in adults with typical age of presentation between third and fifth decades of life. Juvenile hyperparathyroidism is a rare disorder. The common presentations in order of incidence are fatigue and lethargy, headache, nephrolithiasis, nausea, abdominal pain, vomiting and polydipsia. Though skeletal symptoms include bone pains and fractures, but the presence of limb deformity is atypical. We report a case of young girl who presented with isolated progressive genu valgum of both lower limbs and pigeon-shaped chest deformity. She was found to have hypercalcemia and hypophosphatemia with raised parathyroid hormone levels. The neck imaging showed a single adenoma in the left inferior parathyroid gland. The surgical removal of parathyroid adenoma was performed.

    Conclusions and importance: Acute transient cataracts that develop during correction of hyperglycemic hyperosmolar syndrome are thought to result from osmotic lens swelling. In this case report, internal fracture of the lens was produced by mechanical forces generated in the process of lens swelling occurring as a consequence of initial hyperglycemia and its subsequent correction. This case represents a rare ocular complication of hyperglycemia correction, and provides new evidence that mechanical forces can be part of diabetic cataractogenesis.

    Juvenile fibroadenomas are rare and constitute about 0.5% to 4% of all fibroadenomas. They present as circumscribed, often large breast masses in adolescent females and are usually managed with simple enucleation. A 15-year-old girl presented with a 6-month history of rapidly growing breasts. On examination, she was found to have large, diffusely nodular breasts with marked asymmetry. Ultrasound and fine needle aspiration cytology results were suggestive of fibroadenomas, and the patient was planned for excision through a submammary incision. During surgery, both the breasts were found to be studded with nodules of varying sizes with very little normal breast tissue. A bilateral subcutaneous mastectomy was performed for complete removal of the fibroadenomas. Histopathology was reported as multiple juvenile fibroadenomas. Both breasts were later reconstructed with a latissimus dorsi myocutaneous flap with implants. We present this case to highlight a rare indication for bilateral subcutaneous mastectomy for a benign condition of the breast.

    Juvenile granulosa cell tumor (JGCT) of the testis is a rare benign tumor that typically presents as a relatively small (<2 cm) unilateral scrotal mass in neonates or infants. Bilateral JGCT of the testes presenting as large intraabdominal masses in the neonate is very rare. Utilizing preoperative MRI findings, we report a rare case of bilateral JGCT of the testes presenting as large multiseptated abdominal masses originating from undescended intraabdominal testes in a neonate.

    The prevalence of diabetes-related cataracts during childhood is less than 1%. When cataracts occur, it is often in adolescent females with prolonged symptoms and significant hyperglycemia. Cataracts are not a classic feature of monogenic diabetes. We report a case of a 6-yr-old, previously healthy Caucasian male, who presented with bilateral acquired cataracts and was subsequently diagnosed with new onset diabetes. Additional symptoms at presentation included a several year history of polyuria and polydipsia, mild hepatomegaly, and short stature. Pertinent negatives include acanthosis nigricans, lipoatrophy, deafness, muscle weakness, or neuropathy. HbA1c was significantly elevated at diagnosis (>14%, 129.5 mmol/mol) without evidence of ketosis. Autoantibody testing was negative. Features of Mauriac syndrome (short stature, hepatomegaly) as well as acquired cataracts indicated long-standing hyperglycemia with sufficient insulin production to prevent ketone production and development of diabetic ketoacidosis. Whole exome sequencing was conducted and a de novo heterozygous mutation in the INS gene (c.94G>A; p.Gly32Ser) was identified. INS gene mutations are common causes of permanent neonatal diabetes but rare causes of antibody-negative diabetes in children. Importantly, INS gene mutations have not been previously associated with acquired cataracts. Knowledge of a monogenic cause of diabetes allows clinicians to tailor counseling and screening of diabetes-related comorbidities. In summary, this case highlights the need to consider testing for monogenic diabetes, specifically INS gene mutations, in pediatric patients with antibody-negative diabetes, especially if complications of prolonged hyperglycemia are present at diagnosis.

    We report the prenatal detection of a de novo unbalanced complex chromosomal rearrangement (CCR), in a fetus with growth delay and bilateral cataracts. Standard karyotype and FISH analyses on amniotic fluid revealed a complex de novo translocation, resulting in a 46,XY,t(1;12;14)(q42;q14;q32) karyotype. CGH-array showed a significant deletion of 387  kb at 12q14.3, at a distance of only 200-700 kb from the breakpoint at 12q14, which encompassed the HMGA2 gene and occurred de novo. Although 12q14 microdeletions are associated with growth delay in several reports in the literature, we present here the smallest deletion prenatally detected, and we detail the clinical description of the fetus. The correlation between cataracts and this complex genotype is puzzling. Among the genes disrupted by the breakpoint in 12q14, GRIP1 has been associated with abnormal eye development in mice, including lens degeneration. Interestingly, HMGA2 is expressed in the mouse's developing lens, and its expression is decreased in lens of elderly humans, correlated with the severity of lens opacity. In this report, we refine the link between HMGA2 loss of function and growth delay during prenatal development. We also discuss the correlation between cataracts and genotype in this unbalanced CCR case of unexpected complexity.

Slit-lamp examination revealed corneal band-shaped degeneration, KP( -), posterior synechiae of iris in both eyes. In the right eye, lens was cloudy with pigment in the anterior capsule, and in the left eye, the pupil was covered by a fibrous membrane. The fundus of both eyes was not seen. Both of the intraocular pressure were T + 1 by digital measuring. The girl was once diagnosed elsewhere as " uveitis and cataract" , and received cataract surgery and intraocular lens implantation in her left eye 2 years ago. During the following 2 years, she was never regularly treated for the uveitis. This time, she came to our hospital for treating the cataract of the right eye. When seeing a female child with OU anterior uveitis, diagnosis of juvenile rheumatoid arthritis/juvenile idiopathic arthritis should be highly suspected. The keys for the visual prognosis are early treatment on uveitis and appropriate treatment on complications.

    Juvenile idiopathic arthritis (JIA) is an exclusion diagnosis that gathers together all forms of arthritis that begin before the age of 16 years, persist for more than 6 weeks and are of unknown origin. We present the case of a 42 year old woman with a 20 year history of absolute trismus, secondary to bilateral temporomandibular joint (TMJ) ankylosis caused by JIA. The trismus resulted in grossly compromised oral hygiene and limited the patient to a semi-solid diet. JIA also affected her neck leading to a severe cervico-thoracic kyphosis. The patient who had been wheelchair bound developed severe lymphoedema of both lower limbs, complicating the pre-operative work up further. This particularly challenging case required input from specialists in anaesthetics, neurosurgery, special care dentistry, intensive care and maxillofacial surgery. Treatment consisted of ankylosis release, dental clearance and bilateral alloplastic replacement of her TMJs with custom implants. A full range of hinge movement and good functional outcome was achieved. This case presents the multidisciplinary approach to a severely compromised patient and illustrates the pre-, intra- and postoperative management of bilateral TMJ ankylosis with bespoke implants.

    Full Text Available Amblyopia should always be anticipated in children with unilateral cataract, asymmetrical bilateral cataracts (or where there is a delay between the first and second eye operation, or a delay of more than a year between diagnosis/ detection and surgery, cataracts with anisometropia or traumatic cataracts with corneal scars. When amblyopia is detected, occlusion therapy (eye patching must be instituted at the earliest opportunity. The patching regimen is the same with any strabismic amblyopia and sometimes needs to be aggressive at the start. It is crucial to explain the need for patching to the parents, since compliance is the greatest obstacle to the success of amblyopia treatment.

About 20% of patients with juvenile rheumatoid arthritis (JRA) who are negative for IgM rheumatoid factor develop a frequently bilateral, nongranulomatous chronic anterior uveitis. Risk factors for uveitis in JRA patients are: female gender, pauciarticular onset of arthritis, presence of circulating antinuclear antibodies, and the antigens HLA-DW5 and HLA-DPw2. Uveitis is rare after seven years or more have elapsed from the onset of arthritis. The visual prognosis in patients with uveitis is good in 25% and fair in 50%. The remaining 25% develop visual impairment from complicated cataract and/or secondary inflammatory glaucoma. The potential benefit of cytotoxic agents in the treatment of intractable uveitis is outweighed by the risk of serious side effects. The management of secondary inflammatory glaucoma is unsatisfactory, but the results of treatment of complicated cataracts by lensectomy-vitrectomy are good.

    Full Text Available Juvenile primary hypothyroidism causing cystic ovaries and pseudoprecocious puberty (Van-Wyk Grumbach syndrome (VWGS is well documented in literature. There are only a few reports of primary hypothyroidism presenting as ovarian cysts in adults. Here we present a case of huge bilateral ovarian cysts in adulthood as the presenting feature of VWGS due to chronic uncontrolled juvenile hypothyroidism. Large uniloculor right ovarian cyst (119 × 81 × 90 mm and a multicystic left ovary (55 × 45 × 49 mm were detected in a 24 year lady with secondary amenorrhea, galactorrhea, and palpable abdominal mass with history of neonatal jaundice, delayed milestones, short stature, and precocious menarche at age of 7.5 years age. She had elevated levels of cancer antigen (CA-125 which normalized post levothyroxine supplementation. Elevated CA-125 may lead to misdiagnosis of ovarian carcinoma and inadvertent treatment. Bilateral ovarian cysts in adults are a rare presentation of juvenile hypothyroidism. It is necessary to screen for primary hypothyroidism in patients presenting with bilateral ovarian cysts to prevent unnecessary evaluation and treatment.

    Juvenile granulosa cell tumor (JGCT) is an uncommon gonadal stromal tumor that occurs rarely in the testis. We report a newborn boy with bilateral intra-abdominal JGCT presenting with abdominal distention and respiratory distress at birth. He was taken to the operating room emergently, and 2 large masses connected by gubernacula to the inguinal canals were resected. Associated abnormalities included a constitutional chromosome 4 abnormality, polymicrogyria, and renal cysts. This report describes a rare presentation of JGCT with abdominal compression and expands the literature to include bilateral testicular involvement. Additionally, it is the 1st report of JGCT associated with a chromosome 4 abnormality, highlighting a genetic region that may be important in JGCT development.

  16. 连续双眼白内障手术人工晶状体选择的进展%Recent progress on study of the selection of intraocular lens in the bilateral sequential cataract surgery

    Institute of Scientific and Technical Information of China (English)

    张永康; 张宸

    2014-01-01

    Bilateral sequential cataract surgery is very common in clinical,but the ophthalmologists often ignore how to choose the timing of operation and whether the first eye can be used to improve the intraocular lens (IOL) power calculation for the second one.Despite the refinements in IOL selection with the use of third-generation IOL formulas,5% of eyes still result in a postoperative refractive surprise of ± 1.00 D or more.This paper introduced the methods of using refraction error of the first eye to improve the IOL power calculation for the second eye,and the refractive error of the second eye can be improved by modifying the IOL power to correct up to 50% of the error from the first eye in details.Because of the variation of the postoperative refractive surprise within a month,the interval of three to four weeks between two eyes cataract surgery is highly recommended.These conclusions may provide the advantageous guidance for us in the selection of IOL in bilateral cataract surgery.%双眼白内障在短期内先后进行手术在临床上多见,但连续双眼白内障的手术时机以及是否需要根据第一眼的屈光误差来调整第二眼人工晶状体(IOL)的计算是眼科医师容易忽略的问题.尽管手术技术、IOL材料以及IOL计算公式的改进使手术前IOL度数预计与术后实际值之间的误差越来越小,但仍有5%的屈光误差大于±1D.利用第一眼的屈光误差值计算第二眼的IOL方法,通过第一眼的预测误差进行50%的调整可以明显的提高第二眼手术后的效果.同时,由于IOL植入术后1个月内屈光状态的变化,建议双眼手术时间最好间隔3~4周.这为临床中双眼连续白内障手术时机和IOL的选择提供了有利的指导.

    We describe a male patient with a deletion at Xp22, detected by high resolution X-array CGH. The clinical phenotype present in this infant boy, consists of severe encephalopathy, congenital cataracts and tetralogy of Fallot and can be attributed to the deletion of the genes within the interval. Among these deleted genes are the gene for Nance-Horan syndrome and the cyclin-dependent kinase-like 5 gene (CDKL5), responsible for the early seizure variant of Rett syndrome. This is the first description of a male patient with a deletion of these genes, showing the involvement of CDKL5 in severe epileptic encephalopathy in males. Moreover it illustrates the added value of high resolution array-CGH in molecular diagnosis of mental retardation-multiple congenital anomaly cases.

    2017-04-01

    To describe current cataract surgery practices within the United States Veterans Health Administration (VHA). Veterans Health Administration hospitals in the U.S. Retrospective data analysis. An initial e-mail containing a link to an anonymous 32-question survey of cataract surgery practices was sent to participants in May 2016. Two reminder e-mails were sent to nonresponders 1 week and 2 weeks after the initial survey was sent; the remaining nonresponders were called twice over a 2-week period. The data were analyzed using descriptive statistics. The response rate was 75% (67/89). Cataract surgeons routinely ordered preoperative testing in 29 (45%) of 65 sections and preoperative consultations in 26 (39%) of 66 sections. In 22 (33%) of 66 sections, cataract surgeons administered intracameral antibiotics. In 61 (92%) of 66 sections, cataract surgeons used toric intraocular lenses (IOLs). In 20 (30%) of 66 sections, cataract surgeons used multifocal IOLs. Cataract surgeons in 6 (9%) of 66 sections performed femtosecond laser-assisted cataract surgery. In 6 (9%) of 66 sections, cataract surgeons performed immediate sequential bilateral cataract surgery. Forty-nine (74%) ophthalmology chiefs reported a high level of satisfaction with Veterans Affairs ophthalmology. The survey results indicate that in cataract surgery in the VHA, routine preoperative testing is commonly performed and emerging practices, such as femtosecond laser-assisted cataract surgery and immediate sequential bilateral cataract surgery, have limited roles. The results of this survey could benchmark future trends in U.S. cataract surgery practices, especially in teaching hospital settings. Copyright © 2017 ASCRS and ESCRS. Published by Elsevier Inc.

    Full Text Available Purpose: To report a case of bilateral primary intraocular lymphoma. Case report: A 33-year-old man presented with bilateral blurred vision since two years ago. Examination revealed large keratic precipitates, anterior chamber reaction, posterior subcapsular cataracts, and vitreous infiltration. After a short trial of topical and periocular steroids, diagnostic 25-gauge pars plana vitrectomy was performed and cytologic evaluation of the aspirate confirmed a diagnosis of intraocular lymphoma. The patient was subsequently managed with intravitreal methotrexate in both eyes and responded favorably. Central nervous system workup for lymphoma was negative. Conclusion: Primary intraocular lymphoma should be considered in young adults suffering from chronic recalcitrant panuveitis.

  4. Measuring aniseikonia using scattering filters to simulate cataract

    Wilson, Jason

    2011-12-01

    The relationship between anisometropia and aniseikonia (ANK) is not well understood. Ametropic cataract patients provide a unique opportunity to study this relationship after undergoing emmetropizing lens extraction. Because light scatter may affect ANK measurement in cataract patients, its effect should also be evaluated. The Basic Aniseikonia Test (BAT) was evaluated using afocal size lenses to produce specific changes in retinal height. Several light scattering devices were then evaluated to determine which produced effects most similar to cataract. Contrast sensitivity and visual acuity (VA) losses were measured with each device and compared to those reported in cataract. After determining the most appropriate light scattering device, twenty healthy patients with normal visual function were recruited to perform the BAT using the filters to simulate cataract. Cataract patients were recruited from Vision America and the University of Alabama at Birmingham School of Optometry. Patients between 20 and 75 years of age with at least 20/80 VA in each eye, ≥ 2D ametropia, and normal binocular function were recruited. Stereopsis and ANK were tested and each patient completed a symptom questionnaire. ANK measurements using afocal size lenses indicated that the BAT underestimates ANK, although the effect was minimal for vertical targets and darkened surroundings, as previously reported. Based on VA and contrast sensitivity loss, Vistech scattering filters produced changes most similar to cataract. Results of the BAT using Vistech filters demonstrated that a moderate cataract but not a mild cataract may affect the ANK measurement. ANK measurements on cataract patients indicated that those with ≥ 2 D ametropia in each eye may suffer from induced ANK after the first cataract extraction. With upcoming healthcare reform, unilateral cataract extraction may be covered, but not necessarily bilateral, depending on patient VA in each eye. However, a questionnaire about symptoms

    Full Text Available Purpose: The purpose was to estimate the prevalence of blindness due to cataract, assess visual outcomes of cataract surgery, and determine the cataract surgical coverage rate and barriers to uptake of services among individuals aged 50 years or older in Plateau State, Nigeria. Materials and Methods: A population-based, cross-sectional survey of 4200 adults 50 years or older was performed. Multistage stratified random sampling, with probability proportional to size was used to select a representative sample. The Rapid Assessment of Cataract Surgical Services protocol was used. Statistical significance was indicated by (P 0.05. The prevalence of monocular blindness due to cataract was 5.9% (95% CI: 5.2-6.6%. The cataract surgical coverage for subjects with visual acuity (VA less 3/60 was 53.8% in the entire cohort; 60.5% for males and 48% for females (χ2 = 2.49, P > 0.05. The couching coverage for subjects who were blind was 12%. A total of 180 eyes underwent surgical intervention (surgery or couching for cataract, of which, 48 (26.7% eyes underwent couching. The prevalence of bilateral (pseudo aphakia was 1.5%, (95% CI: 1.2-1.9% and 2.7% (95% CI: 2.2-3.2% for unilateral (pseudo aphakia. Visual outcomes of the 180 eyes that underwent surgical intervention were good (VA ≥ 6/18 in 46 (25.6% eyes and poor (VA < 6/60 in 105 (58.3% eyes. Uncorrected aphakia was the most common cause of poor outcome (65.1%. Most subjects who underwent cataract surgery were not using spectacles 74 (71.2%. Cost and lack of awareness were the main barriers to uptake of cataract surgery services. Conclusion: Couching remains a significant challenge in Nigeria. The outcomes of cataract surgery are poor with the lack of aphakic correction being the main cause of the poor outcomes.

  6. Congenital and infantile cataract: aetiology and management.

    2012-04-01

    Congenital cataract is the commonest worldwide cause of lifelong visual loss in children. Although congenital cataracts have a diverse aetiology, in many children, a cause is not identified; however, autosomal dominant inheritance is commonly seen. Early diagnosis either on the post-natal ward or in the community is important because appropriate intervention can result in good levels of visual function. However, visual outcome is largely dependent on the timing of surgery when dense cataracts are present. Good outcomes have been reported in children undergoing surgery before 6 weeks of age in children with unilateral cataract and before 10 weeks of age in bilateral cases. Placement of an artificial intraocular lens implant after removal of the cataract has become established practice in children over 2 years of age. There remains debate over the safety and predictability of intraocular lens implantation in infants. Despite early surgery and aggressive optical rehabilitation, children may still develop deprivation amblyopia, nystagmus, strabismus, and glaucoma. The diagnosis and management of congenital cataracts has improved substantially over the past 30 years with a concurrent improvement in outcomes for affected children. Many aspects of the pre-, intra-, and postoperative management of these patients continue to be refined, highlighting the need for good quality data and prospective collaborative studies in this field.

  7. Reversible monocular cataract simulating amaurosis fugax.

    1985-07-01

    In a patient having brittle, juvenile-onset diabetes, transient monocular visual loss occurred repeatedly whenever there were wide fluctuations in serum glucose. Amaurosis fugax was suspected. The visual loss differed, however, in that it persisted over a period of hours to several days. Direct observation eventually revealed that the relatively sudden change in vision of one eye was associated with opacification of the lens and was not accompanied by an afferent pupillary defect. Presumably, a hyperosmotic gradient had developed with the accumulation of glucose and sorbitol within the lens. Water was drawn inward, altering the composition of the lens fibers and thereby lowering the refractive index, forming a reversible cataract. Hypoglycemia is also hypothesized to have played a role in the formation of a higher osmotic gradient. The unilaterality of the cataract is attributed to variation in the permeability of asymmetric posterior subcapsular cataracts.

    Pyridoxine-dependent epilepsy (PDE) is a cause of neonatal epileptic encephalopathy not previously known to cause ophthalmic disease. We describe the novel observation of a 5-year-old girl with pyridoxine-dependent epilepsy and bilateral cataracts. PDE is the result of mutations in the ALDH7A1 gene encoding antiquitin, an enzyme protective against cellular dehydration and osmotic stress. Accumulating metabolic precursors in PDE have been shown to be cataractogenic in vitro, and experimental pyridoxine deficiency has been associated with lenticular opacities in vivo. The association of ALDH7A1 haploinsufficiency in PDE and congenital cataract may offer insight into the relationship between osmotic stress and fetal cataract development. Bilateral progression of cataracts in this child suggests ongoing metabolic dysregulation within the crystalline lens despite pyridoxine supplementation at doses sufficient to control seizure activity.

Very low birth weight (birth weight (1500-2499 g) was only associated with bilateral cataracts (OR, 3.3; 95% CI, 1.3-8.1). Infants with unilateral cataracts were more likely to be born to primigravid women (OR, 1.6; 95% CI, 1.0-2.7) than women with > or =2 previous pregnancies, although this was of borderline significance. Although not significant, effect estimates were elevated suggesting a possible association between unilateral cataracts and maternal substance abuse during pregnancy, and between bilateral cataracts and urinary tract infection during pregnancy and aspirin use during pregnancy. Very low birth weight is associated with both bilateral and unilateral cataracts, whereas low birth weight is associated with bilateral cataracts and primigravidity with unilateral cataracts.

    Full Text Available AIM: A blindness prevalence survey in 1996 indicated that estimates of 40000 are blind from cataracts in Kano state, northwestern Nigeria. Many more were severely visually impaired. Eye care personnel and other resources for eye care delivery are located at the state capital. The state Ministry of Health organized an outreach program. The aim was to operate on 750 cataract patients and measure the visual acuity at two weeks follow up. METHOD: Patients were registered and examined. Cataract patients with accurate four quadrant light projection, briskly reacting pupils and normal intra ocular pressures were selected and had manual extra capsular cataract extraction with posterior chamber intra ocular lens implantation. Post operative medications were administered. Patients were reviewed at 2 weeks follow up after discharge during which their visual acuity was measured and recorded. RESULTS: 868 cataract patients were operated. Thirty two percent of the patients were blind before surgery and 77% of these had bilateral cataracts. The proportion of those who had posterior chamber intra ocular lens (PC IOL was 85%. The proportion of patients who regained normal vision was 43% and overall, 94% had vision of 6/60 or, better after surgery compared with 20% in this category before surgery, (WHO vision category 0 and 1. CONCLUSION: Cataract outreach service is essential in reducing cataract blindness. There is need to follow up patients although the vision recorded for this study was obtained at two weeks follow up.

    Hereditary cataract is a common ocular disorder in the purebred dog population and is a leading cause of visual impairment and blindness in dogs. Despite this, little is known to date about the genetics underlying this condition. We have used a genome-wide association study and targeted resequencing approach to identify a novel locus for cataracts in the Australian Shepherd breed of dog, using dogs that are clear of an HSF4 mutation, previously identified as the major susceptibility locus in this breed. Cataract cases were defined as dogs with bilateral posterior cataracts, or bilateral nuclear cataracts. Controls were at least 8 years of age with no evidence of cataracts or other ocular abnormality. Using 15 bilateral posterior polar cataract cases and 68 controls, we identified a genome-wide statistical association for cataracts in the Australian Shepherd on canine chromosome 13 at 46.4 Mb (P value: 1.5 × 10(-7)). We sequenced the 14.16 Mb associated region in ten Australian Shepherds to search for possible causal variants underlying the association signal and conducted additional fine-mapping of the region by genotyping 28 intronic variants that segregated correctly in our ten sequenced dogs. From this analysis, the strongest associated variants were located in intron 5 of the SCFD2 gene. Further study will require analysis of additional cases and controls and ocular tissue from dogs affected with bilateral cataracts that are free of the HSF4 mutation.

    2012-06-01

    Full Text Available The utility value was compared among 3 surgical interventions, and the validity of the time trade-off (TTO method was evaluated by analyzing the correlations of the utility value with the results of the Visual Function Questionnaire-14 (VF-14 and other variables. The subjects were 127 patients aged 40-85 years who were surgically treated between January 2008 and March 2010, including 26 patients with glaucoma, 50 with cataracts, and 51 with comitant strabismus. The scores on VF-14 and utility values determined using TTO were calculated retrospectively. The mean value (SD of the utility gain was 0.096 (0.105 for glaucoma, 0.101 (0.105 for comitant strabismus, and 0.167 (0.237 for unilateral and 0.245 (0.167 for bilateral cataracts, indicating significant postoperative improvements in the utility value. A significant correlation was observed between the utility value and the postoperative VF-14 scores of the bilateral cataracts, and the postoperative visual acuity of the better eye of the unilateral cataract. The mean value of the quality-adjusted life years was 2.181 for bilateral and 1.424 for unilateral cataracts, 1.132 for strabismus, and 0.870 for glaucoma with an annual discount rate of 3%. The gain of utility value was highest in bilateral cataracts, and lowest in glaucoma, and thus the TTO analysis was considered to be highly valid for cataract surgery.

  1. Genetics of Congenital Cataract.

    Science.gov (United States)

    Pichi, Francesco; Lembo, Andrea; Serafino, Massimiliano; Nucci, Paolo

    2016-01-01

    Congenital cataract is a type of cataract that presents at birth or during early childhood, and it is one of the most easily treatable causes of visual impairment and blindness during infancy, with an estimated prevalence of 1-6 cases per 10,000 live births. Approximately 50% of all congenital cataract cases may have a genetic cause, and such cases are quite heterogeneous. Although congenital nuclear cataract can be caused by multiple factors, genetic mutation remains the most common cause. All three types of Mendelian inheritance have been reported for cataract; however, autosomal dominant transmission seems to be the most frequent. The transparency and high refractive index of the lens are achieved by the precise architecture of fiber cells and homeostasis of the lens proteins in terms of their concentrations, stabilities, and supramolecular organization. Research on hereditary congenital cataract has led to the identification of several classes of candidate genes that encode proteins such crystallins, lens-specific connexins, aquaporin, cytoskeletal structural proteins, and developmental regulators. In this review, we highlight the identified genetic mutations that account for congenital nuclear cataract.

    Full Text Available Cataract surgery in uveitic eyes is often challenging and can result in intraoperative and postoperative complications. Most uveitic patients enjoy good vision despite potentially sight-threatening complications, including cataract development. In those patients who develop cataracts, successful surgery stems from educated patient selection, careful surgical technique, and aggressive preoperative and postoperative control of inflammation. With improved understanding of the disease processes, pre- and perioperative control of inflammation, modern surgical techniques, availability of biocompatible intraocular lens material and design, surgical experience in performing complicated cataract surgeries, and efficient management of postoperative complications have led to much better outcome. Preoperative factors include proper patient selection and counseling and preoperative control of inflammation. Meticulous and careful cataract surgery in uveitic cataract is essential in optimizing the postoperative outcome. Management of postoperative complications, especially inflammation and glaucoma, earlier rather than later, has also contributed to improved outcomes. This manuscript is review of the existing literature and highlights the management pearls in tackling complicated cataract based on medline search of literature and experience of the authors.

    Full Text Available The management of congenital cataract is very different to the treatment of a routine age-related cataract. In adults, surgery may be delayed for years without affecting the visual outcome. In infants, if the cataract is not removed during the first year of life, the vision will never be fully regained after surgery. In adults, if the aphakia is not corrected immediately, it can be corrected later. In young children, if the aphakia is not corrected, the vision will never develop normally.

    Full Text Available Guy SalletDepartment of Opthamology, Aalsters Stedelijk Ziekenhuis, BelgiumAbstract: A cataract surgery technique is described in which incisions, continuous circular capsulorhexis and hydrodissection are made without the use of any viscoelastics. Two small incisions are created through which the different parts of the procedure can take place, maintaining a stable anterior chamber under continuous irrigation. Subsequent bimanual phacoemulsification can be done through these microincisions. At the end of the procedure, an intraocular lens can be inserted through the self-sealing incision under continuous irrigation. 50 consecutive cataract patients were operated on without the use of viscoelastics and then compared with a group of 50 patients who had been helped with viscoelastics. No difference in outcome, endothelial cell count or pachymetry was noted between the two groups. No intraoperative complication was encountered. Viscoless cataract surgery was a safe procedure with potential advantages.Keywords: ophthalmic visco-surgical device, viscoless cataract surgery, microincision

  5. Cataract Surgery Tool

    Science.gov (United States)

    1977-01-01

    The NASA-McGannon cataract surgery tool is a tiny cutter-pump which liquefies and pumps the cataract lens material from the eye. Inserted through a small incision in the cornea, the tool can be used on the hardest cataract lens. The cutter is driven by a turbine which operates at about 200,000 revolutions per minute. Incorporated in the mechanism are two passages for saline solutions, one to maintain constant pressure within the eye, the other for removal of the fragmented lens material and fluids. Three years of effort have produced a design, now being clinically evaluated, with excellent potential for improved cataract surgery. The use of this tool is expected to reduce the patient's hospital stay and recovery period significantly.

    Full Text Available Studies on hereditary congenital cataracts have led to the identification of genes involved in formation of these cataracts. Knowledge of the structure and function of a particular gene and the effect of disease-associated mutations on its function are providing insights into the mechanisms of cataract. Identification of the disease gene requires both the relevant clinical data as well as genetic data on the entire pedigree in which the disease is found to occur. Genes for hereditary cataract have been mapped by genetic linkage analysis, in which one examines the inheritance pattern of DNA markers throughout the genome in all individuals of the pedigree, and compares those with the inheritance of the disease. Cosegregation of a set of markers with disease implies that the disease gene is present at the same chromosomal location as those markers. The genes so far identified for hereditary cataracts in both humans and animal models encode structural lens proteins, gap junction proteins, membrane proteins and regulatory proteins involved in lens development. Understanding of the mechanisms of hereditary cataract may also help us understand the manner in which environmental and nutritional factors act on the lens to promote opacification.

    A 5-year-old male presented with bilateral poor vision, esotropia and a previous diagnosis of cataract since he was 1 year old. The physical examination revealed bilateral posterior paracentric capsule opacification, vitreous cavity with a permeable pulsatile blood filled hyaloid artery in both eyes. He was kept under observation. Persistent hyaloid artery is an uncommon faulty primary vitreous regression, often unilateral (although it may be bilateral) and sporadic, associated with microphthalmos. It may be complicated with glaucoma and phthisis bulbi. Vitrectomy plus lensectomy or simple observation are the accepted treatment options. Copyright © 2012 Sociedad Española de Oftalmología.

    Operations for congenital cataract in children in the past had resulted in aphakia. Improvement in surgical tools and techniques as well as in intraocular lens (IOL) implantation has led to correction of the aphakia by IOL implantation. We report the outcome of cataract surgery with and without IOL on these children in our institution between 1991-2008. In this retrospective cohort study, the medical records of all children who underwent surgery for congenital cataract were reviewed. The final study group included 144 children (218 eyes). Postoperative visual acuity (VA) was tested either by Teller Acuity Cards (in preverbal children) or by the Snellen chart. Data on VA status and postoperative complications were retrieved. Patients with bilateral cataract had better postoperative VA than patients with unilateral cataract (logMAR 0.559 ± 0.455 vs. 0.919 ± 0.685, respectively, P ECCE) + IOL implantation group than in the ECCE only group (20.6 % vs. 8.3 %, respectively, P = 0.018). Patients with bilateral cataract had better postoperative VA compared with those with unilateral cataract. The type of surgery had no effect on final VA, but there was a higher rate of secondary cataract in the ECCE + IOL patients compared to the ECCE only patients.

    This study aimed to investigate the prevalence and clinical determinants of cataract and cataract surgery in Korean population. The 2008-2012 Korean National Health and Nutrition Examination Survey was analyzed, which included 20,419 participants aged ≥ 40 years. The survey is a multistage, probability-cluster survey, which can produce nationally representative estimates. Prevalence of cataract and cataract surgery was estimated. Clinical determinants for those were investigated using logistic regression analyses (LRAs). The prevalence of cataract was 42.28% (95% confidence interval [CI], 40.67-43.89); 40.82% (95% CI, 38.97-42.66) for men and 43.62% (95% CI, 41.91-45.33) for women (P = 0.606). The prevalence of cataract surgery was 7.75% (95% CI, 7.30-8.20); 6.38% (95% CI, 5.80-6.96) for men and 9.01% (95% CI, 8.41-9.61) for women (P Cataract was associated with older age (P Cataract surgery was consistently associated with older age, occupation, DM, asthma, and anemia in two LRAs, which compared participants with cataract surgery to those without cataract surgery and those having a cataract but without any cataract surgery, respectively. Hypertension, arthritis, and dyslipidemia were associated with cataract surgery at least in one of these LRAs. These results suggest that there are 9.4 million individuals with cataract and 1.7 million individuals with cataract surgery in Korea. Further studies are warranted to reveal the causality and its possible mechanism of developing/exacerbating cataract in novel determinants (i.e., anemia, asthma, and arthritic conditions) as well as well-known determinants.

    A patient with cataracts and congenital exotropia underwent combined cataract and strabismus surgery OU. A lateral rectus recession plus an extracapsular cataract extraction with intraocular lens implantation was done OD first; three months later, this procedure was repeated OS. The patient's postoperative course was benign in both cases, and her strabismus resolved after the second operation. A combined surgical approach to cataracts and strabismus (where only a single muscle is involved) was safe and useful in restoring this patient's vision, binocularity, and appearance.

    2014-05-01

    Congenital cataract is a rare disease whose incidence is estimated to 0.5% of birth in France. A study of the literature shows that congenital cataract is idiopathic in 50% of cases, hereditary forms representing 25% of cases. Other causes of congenital cataract are represented by viral embryofoetopathies acquired during pregnancy, metabolic disorders and chromosomal aberrations within the scope of malformative syndromes. The authors report the case of a neonatal diagnosis of Lowe syndrome suspected by the discovery of bilateral cataract initially isolated. The morphological exploration was completed by secondary brain abnormalities (periventricular lesions). The etiological prenatal exploration was negative. Lowe syndrome is a rare cause of antenatal cataract, which so far only one case has been reported.

    Full Text Available Purpose. To present a case of cataract surgery performed in a patient with a refractive corneal inlay in place. Methods. A 48-year-old female patient presented to our institute with bilateral cataract. The patient had undergone refractive corneal inlay implantation three years ago in her right, nondominant eye for presbyopia correction. Biometry and intraocular lens (IOL power calculation were performed without removing the inlay. Phacoemulsification and IOL insertion were carried out in both eyes in a usual manner. Results. On day one postoperatively, the patient achieved binocular uncorrected distance visual acuity 20/20 and uncorrected near visual acuity J1. The vision remained stable during the one-year follow-up period. Conclusion. Cataract surgery was performed in a standard manner in a patient with Presbia Microlens corneal inlay in place. Visual outcomes for both near and distance vision were satisfactory.

  17. Mutations in the EPHA2 gene are a major contributor to inherited cataracts in South-Eastern Australia.

    Directory of Open Access Journals (Sweden)

    Alpana Dave

    Full Text Available Congenital cataract is the most common cause of treatable visual impairment in children worldwide. Mutations in many different genes lead to congenital cataract. Recently, mutations in the receptor tyrosine kinase gene, EPHA2, have been found to cause congenital cataract in six different families. Although these findings have established EPHA2 as a causative gene, the total contribution of mutations in this gene to congenital cataract is unknown. In this study, for the first time, a population-based approach was used to investigate the frequency of disease causing mutations in the EPHA2 gene in inherited cataract cases in South-Eastern Australia. A cohort of 84 familial congenital or juvenile cataract index cases was screened for mutations in the EPHA2 gene by direct sequencing. Novel changes were assessed for segregation with the disease within the family and in unrelated controls. Microsatellite marker analysis was performed to establish any relationship between families carrying the same mutation. We report a novel congenital cataract causing mutation c.1751C>T in the EPHA2 gene and the previously reported splice mutation c.2826-9G>A in two new families. Additionally, we report a rare variant rs139787163 potentially associated with increased susceptibility to cataract. Thus mutations in EPHA2 account for 4.7% of inherited cataract cases in South-Eastern Australia. Interestingly, the identified rare variant provides a link between congenital and age-related cataract.

  20. Connexin mutants and cataracts

    Directory of Open Access Journals (Sweden)

    Eric C Beyer

    2013-04-01

    Full Text Available The lens is a multicellular, but avascular tissue that must stay transparent to allow normal transmission of light and focusing of it on the retina. Damage to lens cells and/or proteins can cause cataracts, opacities that disrupt these processes. The normal survival of the lens is facilitated by an extensive network of gap junctions formed predominantly of connexin46 and connexin50. Mutations of the genes that encode these connexins (GJA3 and GJA8 have been identified and linked to inheritance of cataracts in human families and mouse lines. In vitro expression studies of several of these mutants have shown that they exhibit abnormalities that may lead to disease. Many of the mutants reduce or modify intercellular communication due to channel alterations (including loss of function or altered gating or due to impaired cellular trafficking which reduces the number of gap junction channels within the plasma membrane. However, the abnormalities detected in studies of other mutants suggest that they cause cataracts through other mechanisms including gain of hemichannel function (leading to cell injury and death and formation of cytoplasmic accumulations (that may act as light scattering particles. These observations and the anticipated results of ongoing studies should elucidate the mechanisms of cataract development due to mutations of lens connexins and abnormalities of other lens proteins. They may also contribute to our understanding of the mechanisms of disease due to connexin mutations in other tissues.

    To collect cataract surgery rates data in 19 Latin American countries over a 4-year period as data published to date have been limited. Cataract surgery rates were obtained from National Society of Ophthalmology, National VISION 2020/Prevention of Blindness Committee and Ministry of Health representatives for each country for 2005 to 2008. Economic (gross national income per capita) and other data were collected from publicly available databases. Linear and power correlations between gross national incomes and cataract surgery rates were calculated. Over the study period, most countries increased their cataract surgery rates, with the largest increases observed for Venezuela (186%), Nicaragua (183%), Costa Rica (100%), Uruguay (97%), and Peru (88%). Mean cataract surgery rates for 2005, 2006, 2007, and 2008 for the ensemble of countries were 1545, 1684, 1660, and 1822 per million population, respectively, with a growth over the study period of 17.9%, concurrent with an increase of 57 million (11.5%) in the population. A good correlation between cataract surgery rate and gross national income per capita was found (P < .001). Although progress is being made in the region, the cataract surgery rates represent only one parameter. When they are examined in the context of cataract surgical coverage it is clear that substantial proportions of bilaterally blind persons are still not receiving surgery.

    Purpose:.Our aim was to obtain a better understanding of the etiologies and characteristics of pediatric cataracts treated at a single facility in China.Methods:.Medical records accrued over a 10-year period (from August, 2003 to July, 2013) at Shengjing Hospital of China Medical University were reviewed retrospectively , ide ntifying all patients treated for various subtypes of pediatric cataract..A database with 367 subjects under 14 years of age (598, including second-round surgeries) was generated.Results:.Of this cohort (n =367; males: 232, 63.2% ; fe-males: 135, 36.8%), 200 patients (54.5%) had bilateral cataracts, and 258 (70.3%) were under 3 years of age. In all age groups and in all subtypes of pediatric cataract,.males were most commonly affected..Congenital cataract was the most prevalent subtype, accounting for 296 patients (80.7%). Most congeni-tal cataracts were associated with other ocular or systemic ab-normalities;.and in 48 patients (16.22%),.they were heredi-tary..Traumatic cataract was the most common subtype (85.92%) of acquired cataract. The few instances of cataracts due to steroids (n=3) or to metabolic disorders (n=2) occurred in males and involved both eyes.Conclusion: The majority of pediatric cataracts in this patient population were congenital in nature. A significant lag in oph-thalmologic evaluation of Chinese infants was evident and should be addressed by educating both children and parents on risk factors for cataract development. Regular assessments are especially important in children subjected to long-term sys-temic steroid treatments. (Eye Science 2014; 29:138-142)

    Extracapsular cataract extraction and intraocular lens implantation was performed on 4 eyes of 3 patients with radiation cataract. Case 1 was a 60-year-old man who was exposed to the ionizing radiation of the atomic bomb in Hiroshima 730 meters from the center of the explosion. He developed atomic bomb radiation senile cataracts in both eyes. Despite cataract surgery, a central plaque remained on the posterior capsule in the region corresponding to the central dense opacity in both eyes. Case 2 was an 81-year-old man who was in a streetcar 1,000 meters from the center of the explosion at the time of the atomic bombing. Senile and radiation-induced cataract decreased the visual acuity in both eyes. After extracapsular cataract extraction in his right eye, central opacification and a fibrous white membrane remained on the posterior capsule. These were removed by Nd-YAG laser capsulotomy six days after surgery. Case 3 was a 56-year-old man who developed radiation cataract after radiation therapy to a malignant lymphoma in the right orbit. Phacoemulsification and aspiration could not remove the fibrous white membrane from the posterior capsule in this case. Central opacities and fibrous white membranes on the posterior capsule after cataract surgery appears to be a characteristic of radiation cataract. (author).

    The intraocular lens restores general vision and some degree of independence and mobility to patients with dense cataracts and macular degeneration. The patient, however, must be repeatedly warned that fine central vision, particularly reading, will not be possible after the surgery. An aphakic spectacle leaves such patients a narrow band of vision when superimposed over the macular lesion, and contact lenses are too small for the patient to manage insertion without help.

    1999-01-01

    Full Text Available Purpose: To estimate the prevalence of bilateral cataract blindness in persons ≥50 years of age in Ahmedabad district, Gujarat. Methods: A total of 1,962 persons ≥50 years of age were examined in clusters of 45 people or less. The survey design used a systematic random cluster sampling. The sample size was calculated assuming a prevalence of bilateral cataract blindness (visual acuity <3/60 of at least 3% and design effect of 1.6, to estimate the actual prevalence of cataract blindness with a sampling error of ≤20 at 80% confidence level. Visual acuity was assessed with glasses, where available, and pinhole was used for visual acuity <6/18. Distant direct ophthalmoscopy in semidark condition with undilated pupil was used to assess the lens status. Results: The age-gender-adjusted prevalence of all blindness was 2.9% in persons ≥50 years of age (6.7% for visual acuity<6/60. The age-gender-adjusted prevalence of bilateral cataract blindness ( visual acuity <3/60 was 1.2% in persons ≥50 years of age. For visual acuity <6/60, the prevalence was 3.1%. The prevalence in females was slightly higher than in males. The prevalence of bilateral and unilateral aphakia and pseudophakia was high. The cataract surgical coverage, an indicator for coverage and service utilization, was 92.9% for persons and 83.1% for eyes. Conclusion: Rapid assessment of cataract blindness in persons ≥50 years of age can be conducted in urban settings with existing resources and at affodable costs, to provide district level data for assessment and monitoring of cataract intervention programs.

    Cataract is a loss of lens transparency because of a protein alteration. Etiopathogenesis is poorly understood but new mutations of different developmental genes involved are found in 25% of cases. Frequency of onset, particularly when different ocular development anomalies occur, is related to the lens induction phenomena on the eye's anterior segment structure during embryologic development. Genetic transmission is often found on the dominant autosomal mode. Diagnosis is based on a complete and detailed examination of the eye, often with general anaesthesia. This condition predisposes children to later, sometimes serious amblyopia. Different clinical aspects can be observed: from cataract with ocular and/or systemic anomalies to polymalformative syndrome, skeletal, dermatological, neurological, metabolic, and genetic or chromosomal diseases. A general systematic pediatric examination is necessary. Congenital cataract requires first and foremost early diagnosis and a search for all etiologies. Surgical treatment is adapted case by case but it has progressed with the quality of today's intraocular lenses even if systematic implantation continues to be debated. Life-long monitoring is absolutely necessary.

    A 38-year-old man with brittle, juvenile onset diabetes mellitus and bilateral severe dry eyes with recurrent corneal ulcers developed atypical band-shaped calcifications of both corneas during a 24-hour period. Serum calcium, phosphate, and carbon dioxide levels all were within normal limits. The patient was mildly uremic but was not in renal failure. When EDTA chelation failed to clear the deposits, partial keratectomies were performed in both eyes and the specimens were examined by light and electron microscopy, including energy dispersive x-ray analysis. Microscopic studies revealed an atypical calcific keratopathy which involved neither Bowman's layer nor the most superficial stromal lamellae. The deposits were confined to deeper lamellae in the anterior stroma and by electron microscopy were composed of extracellular crystalline aggregates. Energy dispersive x-ray analysis of these aggregates confirmed the presence of calcium and phosphate. Corneal dessication appeared to be a major contributing factor in the rapid formation of these deposits.

    Full Text Available Background. A six-year-old boy presented with a large progressive intracorneal and scleral cyst. Two years before, bilateral cataract surgery through a 6.5-mm corneal incision was performed elsewhere.Methods. The posterior wall of the cyst could be excised, as well as the anterior wall in the sclera. Upon histo-pathology the cyst wall was lined by epithelium. The epithelial cells of the anterior side in the cornea were removed with a curette and a corpus alienum drill. Three and a half years after removal of the cyst, there was no recurrence. Visual acuity was 0.8. Conclusions. An intracorneal and scleral inclusion cyst was successfully removed by surgical excision and the removal of epithelial cells by a curette and a corpus alienum drill.

    Twenty 6-yr-old (1995-yr-class) Gulf of Mexico sturgeon (Acipenser oxyrinchus desotoi) were diagnosed as having bilateral cataracts. Histopathologic assessment of the lenses of two of the fish revealed the presence of a diplostomid trematode. Pharmacological treatment of the trematodes may be effective for killing the parasites, but the damage to the lenses and resulting cataracts are nonreversible. Because these animals were to be used in a subsequent study as sentinels in the natural environment, it was necessary to return the animals' vision to as close to normal as possible. Electroretinograms were performed on each fish's eyes to ensure that retinal function was present. Cataracts then were surgically removed by phacoemulsification and aspiration. The animals tolerated the surgical procedures well. This report is the first known report of surgical correction of cataracts in sturgeon species. It also is the first known attempt to correct vision problems in fish being returned to the wild.

    A 5 year old boy was presented at Eye clinic University clinical center Tuzla with congenital aniridia in both eyes. Clinical examination revealed visual acuity of 0,08 without correction in right and 0.7 with -5.0 Dsph and -1.0 Dcyl Axx 109° in left eye. Opthalmologic examination showed bilateral aniridia associated with moderate cataract in the right and incipient cataract in the left eye. In the right eye, zonular weakness with incipient capsular displacement and esotropia of Δ6º, were noted. The patient underwent phacoemulsification, implantation of capsular tension ring and Artificial Iris implant in the capsular bag. Phacoemulsification went uneventful and early postoperative recovery was successful with no signs of aniridia-associated keratopathy development and normal values of intra ocular pressure. Patient was not motivated for operation of the left eye and it was corrected with soft contact lens. Six month after the operation visual acuity in the right eye improved to 0.9 with +1.25Dsph and maintained stable in left eye, with complete elimination of esotropia and signs of binocular vision restoration. Small incision cataract extraction with IOL and Artificial Iris implantation in one procedure can be used to correct congenital aniridia and cataract with significant visual function improvement.

  19. Congenital cataracts and other abnormalities in a female with 46.X, del(X)(q26q28)mat: A new locus for X-linked congenital cataract?

    Three forms of X-linked congenital cataracts have been delineated: congenital cataract with posterior Y-sutural opacities in heterozygotes, congenital cataract and microcornea or microphthalmia and congenital cataract-dental syndrome (Nance-Horan syndrome). Of these, only the Nance-Horan syndrome has been mapped to Xp22.3-p21.1. However, Warburg has suggested that these different forms of X-linked congenital cataracts are due to deletions of varying sizes, placing them in the vicinity of the Nance-Horan syndrome region. We report on a female patient born to a 29-year-old primigravida woman who at birth was found to have hypotonia, dysmorphic facial features, hydrocephalus and dense white congenital bilateral cataracts. Other ophthalmological findings included bilateral nystagmus and shallow orbits. Chromosome analysis revealed 46,X,del(X)(q26q28)mat. The mother, however, is phenotypically normal. Brain CT scan on the female infant revealed communicating hydrocephalus and a muscle biopsy showed congenital muscle fiber disproportion. An EMG and NCV were normal. At 4 years of age, her height and weight were below -3SD and her OFC was +2SD. Molecular studies using DNA markers located in Xq26-qter have revealed that the proximal breakpoint in the patient and her mother is defined by the HPRT locus while the distal breakpoint is defined by the locus DXS1108. This indicates that the deletion is not terminal but rather interstitial, retaining sequences proximal to the telomeric region. Other molecular studies are in progress to determine the X-inactivation status of the deleted chromosome in our patient and her mother as a possible explanation for the variation in the phenotype. These clinical and molecular findings suggest that another locus for X-linked congenital cataract exists at Xq26-28.

    Full Text Available Natural eye lens is a crystalline substance to produce a clear passage for light. Cataract is opacity within the clear lens of the eye and is the dominant cause of socio-medical problem i.e., blindness worldwide. The only available treatment of cataract is surgery. However, insufficient surgical facilities in poor and developing countries and post-operative complications inspire researchers to find out other modes of treatment for cataract. In this review, an attempt has been made to appraise various etiological factors of cataract to make their perception clear to build up counterpart treatment. Present study is an assortment of various available literatures and electronic information in view of cataract etiopathogenesis. Various risk factors have been identified in development of cataracts. They can be classified in to genetic factors, ageing (systemic diseases, nutritional and trace metals deficiencies, smoking, oxidative stress etc., traumatic, complicated (inflammatory and degenerative diseases of eye, metabolic (diabetes, galactosemia etc., toxic substances including drugs abuses, alcohol etc., radiation (ultraviolet, electromagnetic waves etc. are implicated as significant risk factors in the development of cataract.

To our best knowledge, this is the first case-control study with a large number of participants to evaluate ocular blood flow in patients with cataracts.Materials and methods: Color Doppler and duplex sonography of the orbital vessels was performed in 224 eyes of 112 patients with known bilateral age-related cataracts and in 76 eyes of 38 healthy age- and sex-matched volunteers.Results: The mean ± (standard deviation [SD] of peak systolic velocity (PSV of the ophthalmic artery in patients with cataracts (34.59 ± 22.49 cm/second was significantly different to that in controls (52.11 ± 14.01 cm/second (P < 0.001. The mean ± SD PSV of the central retinal artery in patients with cataracts (15.31 ± 4.93 cm/second was significantly different to that in controls (9.61 ± 5.64 cm/second (P < 0.001.Conclusion: The mean PSV and resistive index (RI of the ophthalmic and central retinal arteries were lower in cataract patients when compared with normal subjects. This suggests that ocular hypoperfusion and changes in ocular hemodynamic may have a role in the formation of age-related cataracts.Keywords: retrobulbar blood flow, age-related, cataract, color Doppler ultrasonographic

    To evaluate whether separating the procedures in a combined procedure by performing a temporal cataract incision and superior trabeculectomy induces the lower astigmatism of a temporal cataract incision without sacrificing intraocular pressure (IOP) control. EyeSight Associates, Warner Robins, Georgia. This study evaluated 50 consecutive eyes receiving a superior cataract incision with a superonasal trabeculectomy and 65 eyes receiving a temporal cataract incision with a superonasal trabeculectomy. After 3 months, a substantially greater proportion of temporal incision cases had controlled IOP without medication. A substantially higher proportion in the superior incision group had uncontrolled IOP at each time period. Mean surgically induced cylinder was higher in the superior incision group at every time period. The superior group had early with-the-rule mean induced cylinder that decayed to against-the-rule, with a mean induced cylinder with keratometry at the final available visit (more than 3 months) of -1.01 diopter (D). The temporal group started with a negligible induced cylinder (-0.13 D) that drifted slightly with the rule to a final mean induced cylinder of +0.49 D. At the last visit, 31% in the superior incision group and 57% in the temporal incision group had an uncorrected visual acuity of 20/40 or better, and 72% and 94%, respectively, had a best corrected acuity of 20/40 or better. Separating the cataract and glaucoma procedures frees the surgeon to use newer astigmatically neutral techniques for the cataract incision.

    Iatrogenic Cushing syndrome induced by oral and parenteral corticosteroid administration is a well-known complication, and necessary precautions have to be taken. Cushing syndrome, however, following treatment with glucocorticoid-containing eye drops is a very rare complication. To the best of our knowledge, there have been only four reported cases in the literature. Herein, we present an infant boy who developed Cushing syndrome after receiving dexamethasone-containing eye drops after bilateral cataract extraction to prevent postoperative inflammatory complications. At the age of 5 months, after approx. 3 months of dexamethasone therapy, the patient presented with cushingoid facies, nephrocalcinosis and failure to grow. Iatrogenic Cushing syndrome was diagnosed and dexamethasone-containing eye drops were reduced and eventually stopped. Follow-up examinations revealed catch-up growth. Ocularly administered corticosteroids may have substantial systemic side effects in infants.

It is recommended that all neonates be screened by red reflex examination at birth and suspected cases be referred to ophthalmic centers. Early surgery (1 year is highly recommended. After surgery, amblyopia treatment and periodic follow-up examinations should be started as soon as possible to achieve a satisfactory visual outcome. Practitioners should consider the possibility of posterior capsular opacity, elevated intraocular pressure and amblyopia during follow-up, especially in eyes with microphthalmia and/or associated congenital anomalies. All strabismic children should undergo slit lamp examination prior to strabismus surgery to rule out congenital lens opacities. From a social point of view, equal and fair medical care should be provided to all children regardless of gender.

    Full Text Available Two 8- and 9-year-old brothers were referred to the Pediatric Oncology Unit, Perugia General Hospital, because of hyperferritinemia. Both had a history of bilateral cataract and epilepsy. Genetic investigation revealed two distinct mutations in iron haemostasis genes; homozygosity for the HFE gene H63D mutation in the younger and heterozygosity in the elder. Both displayed heterozygosity for C33T mutation in the ferritin light chain iron response element. A 7-year-old boy from another family was referred to our unit because of hyperferritinemia. Genetic analyses did not reveal HFE gene mutations. Family history showed that his mother was also affected by hyperferritinemia without HFE gene mutations. Magnetic resonance imaging in the mother was positive for iron overload in the spleen. Cataract was diagnosed in mother and child. Further genetic investigation revealed the C29G mutation of the ferritin light chain iron response element. C33T and C29G mutations in the ferritin light chain iron response element underlie the Hereditary Hyperferritinemia-Cataract Syndrome (HHCS. The HFE gene H63D mutation underlies Hereditary Haemochromatosis (HH, which needs treatment to prevent organ damages by iron overload. HHCS was definitively diagnosed in all three children. HHCS is an autosomal dominant disease characterized by increased L-ferritin production. L-Ferritin aggregates accumulate preferentially in the lens, provoking bilateral cataract since childhood, as unique known organ damage. Epilepsy in one case and the spleen iron overload in another could suggest the misleading diagnosis of HH. Consequently, the differential diagnosis between alterations of iron storage system was essential, particularly in children, and required further genetic investigation.

    Full Text Available Cataract is the most common cause of blindness in the world. An attack of phacolytic and phacomorphic glaucoma as a result of neglected cataract constitutes a medical emergency that must be addressed immediately. Ocular emergencies such as these is challenging for the surgeon with guarded or poor prognosis. We describe the presentation, management and prognosis of three cases of phacomorphic and phacolytic glaucoma. All three patients underwent aggressive management of intraocular pressure. Despite successful cataract operation with implantation of intraocular lens, there was only mild improvement of the vision. Optic nerve and pupil functions were permanently affected following the insult. Phacomorphic and phacolytic glaucoma present a very challenging problem to the surgeon with poor visual outcome. Public health education and awareness are important and health workers should encourage patients with cataract to seek early treatment for better prognosis.

    Juvenile scleroderma is a rare childhood condition characterized by fibrosis of the skin and internal organs. Clinical manifestations of childhood scleroderma are different from adult disease and early recognition, correct classification and treatment can improve long-term outcome. This review explores the most recent actualizations on clinical manifestations, classification criteria, treatment options and prognosis of juvenile scleroderma. There are two main forms of the disease: localized scleroderma and systemic sclerosis. Localized scleroderma is the most common form in children and mostly restricted to the skin. Juvenile diffuse systemic sclerosis is related to visceral involvement and cardiac disease which is the main cause of death in these patients. The outcome of juvenile systemic sclerosis is better compared with the adult form. Treatment remains a medical challenge and the EULAR task force proposed an approach to juvenile scleroderma treatment based on expert's opinion and guidelines used for the treatment of adults. Larger studies on childhood scleroderma are warranted.

    Full Text Available PURPOSE: To assess the safety and efficacy of Manual Small Incision Cataract Surgery (MSICS in cases of white cataract with the use of trypan blue as an adjunct for performing continuous curvilinear capsulorthexis (CCC. MATERIALS AND METHODS: Prospective observational study on 100 consecutive eyes of 100 patients with white cataract who had undergone MSICS with trypan blue assisted CCC. The nucleus was prolapsed into anterior chamber by using a sinskey hook and extracted out of the eye using irrigating vectis. Intraoperative and postoperative findings (according to OCTET classification as well as postoperative visual outcomes were used as main measures to report the safety and efficacy of the surgery. RESULTS: Of the 100 eyes, 16 had intumescent, 67 had mature and 17 had hypermature cataract. Intraoperatively CCC was incomplete in 4 eyes (4% and had to be converted to canopener capsulotomy. None of the eyes had posterior capsular rupture or zonular dialysis and no eyes were converted to conventional Extra Capsular Cataract Extraction (ECCE. Postoperatively, 6 eyes (6% developed corneal oedema with >10 Descemets folds and 7 eyes (7% had corneal oedema with < 10 Descemets folds. Mild iritis was seen in 6 eyes (6% and moderate iritis with fibrin membrane was seen in 3 eyes (3%. Iridodialysis was observed in 1 eye (1%. Of the 99 patients (99% categorised under good visual outcomes category, 94 patients (94% had a best-corrected visual acuity of 6/9 or better on the 40th post-operative day. CONCLUSION: In developing countries like India where phacoemulsification may not be affordable to a majority of those requiring cataract surgery, MSICS proves to be a safe and efficacious alternative for white cataracts especially with the adjunctive use of trypan blue dye.

    Full Text Available Purpose: To report a rare case of a patient with hypoparathyroidism presenting with bilateral disc swelling and near mature cataract as her first clinical manifestationCase report: A 23-year-old woman presented with complaint of worsening vision since one year ago and a history of refractory seizures and headache for several years, being under treatment with Lamotrigine 50 mg/daily. Slit-lamp examination revealed significant cataracts on both sides. Red reflex was dull in the right eye and absent in the left side. The intraocular pressure (IOP measurement was normal in both eyes (16 mmHg. Her fundus examination revealed disc swelling in her right eye and hazy media that obscured fundus examination due to dense cataract in the left eye. The combination of bilateral disc swelling and dense cataracts raised suspicion to hypoparathyroidism. Subsequently, neuroimaging and intracranial pressure (ICP monitoring was requested along with neuro-ophthalmalogy consultation. The diagnosis was Psedotumor Cerebri. Due to increased ICP, she underwent multiple lumber punctures. Computed tomography (CT scan showed abnormal signal density in basal ganglia suggestive for presence of calcium depositions, making the diagnosis of hypoparathyroidism more probable. Ensuing laboratory result made the definite diagnosis of hypoparathyroidism. Meanwhile the cataract progressed and the visual acuity (VA decreased to HM in her both eyes. She underwent cataract extraction and PCIOL implantation. Papilledema resolved and the vision restored to 20/20.Conclusion: Ocular complaints happens very rare in the course of hypoparathyroidism but still it seems rational that this occasionally fatal condition be ruled out by hormonal evaluation for cases of unexplained cataracts, particularly if it is accompanied by disc swelling.

    Congenital cataracts are the most important cause of severe visual impairment in infants. Genetic factors contribute to the disease development and 29 genes are known to cause congenital cataracts. Identifying the genetic cause of congenital cataracts can be difficult because of genetic heterogeneity. V-maf avian musculoaponeurotic fibrosarcoma oncogene homolog (MAF) encodes a basic region/leucine zipper transcription factor that plays a key role as a regulator of embryonic lens fiber cell development. MAF mutations have been reported to cause juvenile-onset pulverulent cataract, microcornea, iris coloboma, and other anterior segment dysgenesis. We report on six patients in a family who have congenital cataracts were identified MAF mutation by whole exome sequencing (WES). The heterozygous MAF mutation Q303L detected in the present family occurs in a well conserved glutamine residue at the basic region of the DNA-binding domain. All affected members showed congenital cataracts. Three of the six members showed microcornea and one showed iris coloboma. Congenital cataracts with MAF mutation exhibited phenotypically variable cataracts within the family. Review of the patients with MAF mutations supports the notion that congenital cataracts caused by MAF mutations could be accompanied by microcornea and/or iris coloboma. WES is a useful tool for detecting disease-causing mutations in patients with genetically heterogeneous conditions.

    To compare pain and anxiety between first and second cataract extractions under topical anesthesia with monitored anesthesia care. University ophthalmology clinic. Cohort study. Consecutive adults having bilateral sequential clear corneal cataract extraction using phacoemulsification under topical anesthesia with monitored anesthesia care were recruited. Exclusion criteria included baseline eye pain, poor comprehension, and complicated cataract extraction. Patients completed 4 short perioperative surveys with each cataract extraction as follows: the Amsterdam Preoperative Anxiety and Information Scale (APAIS) and the State-Trait Anxiety Scale (STAI) preoperatively and a 0-to-10 visual analog scale pain survey twice after surgery. Pain and difference in pain were the primary outcomes. Of the 65 patients who completed the study, 26 (40%) reported higher visual analog scale pain scores for the second cataract extraction. Overall, the median pain score was 0 (range 0 to 6) for the first cataract extraction and 1 (range 0 to 9) for the second (P = .004). By 1 day postoperatively, the pain scores were similar (median 0; range 0 to 9; P = .58). Both APAIS and STAI anxiety scores decreased between surgeries (P = .003 and P preoperative anxiety and may be related to the amnestic effects of intravenous sedation. These data may explain a common operative observation. No author has a financial or proprietary interest in any material or method mentioned. Copyright © 2011 ASCRS and ESCRS.

    Pierre Robin sequence has been associated with a number of ocular complications, including myopia, strabismus, Möbius syndrome, nasolacrimal duct obstruction, glaucoma, cataract, microphthalmos, coloboma of choroid, and retinal detachment. We report a 10-day-old boy who presented with micrognathia, glossoptosis, and cleft palate as well as multiple congenital anomalies. Ophthalmic examination was notable for bilateral maculopathy, with focal areas of retinal and retinal pigment epithelial atrophy. The association of Pierre Robin sequence and maculopathy has been reported only twice previously.

  19. Bilateral Pseudoexfoliation Deposits on Intraocular Lens Implants

    Full Text Available We present a rare case of bilateral pseudoexfoliative deposits on both intraocular lens (IOL implants in an 83-year-old woman with no other associated pathology, 5 years after cataract surgery. Pseudoexfoliation syndrome is the most common cause of secondary open-angle glaucoma worldwide and these deposits are usually found on the natural lens. The fact that pseudoexfoliative deposits have been found on IOL implants implies the need for a thorough examination in pseudophakic patients, for it could be the only sign of secondary glaucoma.

  20. Topical sulindac therapy in diabetic senile cataracts : cataract IV

    Directory of Open Access Journals (Sweden)

    1989-01-01

    Full Text Available Sulindac, a non-steroidal anti-inflammatory drug has been found to be a potent inhibitor of enzyme aldose reductase. We used sulindac topically in diabetic senile cataract patients to note if it effects the progression of cataracts. More of sulindac treated eyes maintained initial vision and fewer eyes had visual loss of up to two lines or more as compared to control eyes. The extent and density of different opacities showed less progression in sulindac treated eyes but it was not statistically significant except that the ophthalmoscopically observed density of opacity showed statistically very significant lesser mean increase in sulindac treated eyes. We suggest that sulindac is a potential drug which should be further evaluated in large double blind photodocumented studies in diabetic senile cataracts.

    Full Text Available Introduction. Juvenile myasthenia is a chronic autoimmune neuromuscular disease characterized by varying degrees of fluctuating, painless muscle weakness and rapid fatigue of any muscles under voluntary control. Juvenile myasthenia is a form of myasthenia appearing in adolescent age, representing 10% to 15% of all cases of myasthenia gravis. Juvenile myasthenia is presented by a defect in the transmission of nerve impulses to muscles, resulting from a breakdown in the normal communication between nerves and muscles. In myasthenia, antibodies produced by the body’s own immune system block, alter, or destroy the receptors for acetylcholine. Juvenile myasthenia is neither directly inherited nor is it contagious. Signs and Symptoms. The first noticeable symptoms may be eye muscle weakness, difficulty in swallowing, or slurred speech. Juvenile myasthenia usually affects muscles innervated by the cranial nerves (face, lips, tongue, neck and throat, but it can affect any muscle group. Symptoms vary in type and severity with typical periods of exacerbation interspersed with periods of remission. When the muscles necessary for breathing are affected, a patient is said to be in a myasthenic crisis, which is a life-threatening situation. Disease Outcome and Treatment. Juvenile myasthenia produces sporadic but progressive weakness and abnormal fatigability of striated (skeletal muscles, exacerbated by exercise and repeated movement, but improved by rest and anticholinesterase drugs. Juvenile myasthenia follows an unpredictable course of recurring exacerbations and periodic remissions. With current therapies, however, most cases of juvenile myasthenia are not as serious as the name implies. Although there is no known cure, drug treatment has improved prognosis and allows patients to lead relatively normal lives, except during exacerbations.

    Hereditary congenital cataract varies immensely concerning location and form of the lens opacities. A specific and very rare phenotype is called "ant-egg" cataract first described in 1900. "Ant-eggs" have previously been examined using light microscopy, backscattered electron imaging and X-ray scans and electron microscopy. The purpose of this study was to further characterize "ant-egg" cataract using modern technology and display the history of the "ant-eggs" after cataract extraction. "Ant-eggs" were examined using Heidelberg SPECTRALIS Optical Coherence Tomography (OCT)(Heidelberg Engineering, Heidelberg, Germany). Ten "ant-eggs" were extracted; four of these as well as control tissue were analyzed by mass spectrometry (AB Sciex). Proteins were identified and their approximate abundances were determined. Immunohistochemical staining was carried out on the remaining "ant-eggs" for cytokeratin and S100. In anterior OCT-images, the "ant-egg" structures are localized on the iris. Comparative pictures showed that they stayed in the same location for more than 45 years. Mass spectrometry of "ant-eggs" yielded a proteome of 56 different proteins. Eighteen of the 56 "ant-egg" proteins (32 %) were neither present in our controls nor in a known fetal lens proteome. Among these were cytokeratin and Matrix-Gla protein. Immunohistochemical reactions were positive for cytokeratin and S100. This study demonstrates the previously unknown protein composition of the "ant-egg" structures in "ant-egg" cataract. Eighteen of these proteins are not natively found in the human lens. Moreover, "ant-eggs" do not vary over time, after cataract extraction, regarding size and location.

    Purpose:.To interpret the incidence of optic-nerve maldevel-opment in postoperative pediatric cataract patients, and evalu-ate the clinical efficacy of administration of murine nerve growth factor (mNGF) in such patients. Methods: Pattern visual evoked potential (P-VEP) was used to measure the visual pathway function in 28 cases (56 eyes) with bilateral congenital cataract and 13 cases (13 eyes) with unilateral congenital cataract who underwent cataract extrac-tion and intraocular lens implantation surgeries..The results were compared with 25 age-sex-matched healthy children (50 eyes)..mNGF was administered in 13 cases (23 eyes) who had visual pathway disorder..The efficacy of mNGF injection was observed. P100 latencies, which were used as a main parame-ter in P-VEP measurement, were analyzed statistically. Results:.When compared with normal children, the P100 la-tency was significantly prolonged in the congenital cataract group (P Conclusion: Compared with normal children, the congenital cataract patients are more vulnerable to optic-nerve maldevel-opment. Murine NGF likely plays a protective and nutritive role in the development of optic nerve in cases of optic-nerve maldevelopment followed by congenital cataract surgery.

    Congenital cataracts are an important cause of bilateral visual impairment in infants. Through genome-wide linkage analysis in a four-generation family of Irish descent, the disease-associated gene causing autosomal-dominant congenital nuclear cataract was mapped to chromosome 4p16.1. The maximum logarithm of odds (LOD) score was 2.62 at a recombination fraction θ=0, obtained for marker D4S432 physically close to the Wolfram gene (WFS1). By sequencing the coding regions and intron-exon boundaries of WFS1, we identified a DNA substitution (c.1385A-to-G) in exon 8, causing a missense mutation at codon 462 (E462G) of the Wolframin protein. This is the first report of a mutation in this gene causing an isolated nuclear congenital cataract. These findings suggest that the membrane trafficking protein Wolframin may be important for supporting the developing lens.

    Full Text Available Pur po se: To evaluate the incidence of strabismus in pediatric cataracts and the effects of strabismus and nystagmus accompanied by cataract on postoperative visual acuity. Ma te ri als and Met hod: Seventy-four eyes of 45 patients under 15 years old who had undergone cataract operation were included in this study. The mean postoperative follow-up period was 1.57±2.25 years (ranged between 3 months and 9 years. Twenty-nine of the patients (64% had bilateral and 16 of the patients (36% had unilateral cataract. Preoperative and postoperative visual acuities, as well as the presence of nystagmus and strabismus were recorded. Re sults: Seventeen of the patients (38% had strabismus: 9 of them (53% had esotropia (ET, and 8 of them had (47% exotropia (XT. Fourteen (19% of the total number of cases had nystagmus. The mean age was 5.8±4.4 years for the total group of patients, 4.6±3.0 years for patients with strabismus and 5.1±3.7 years for patients with nystagmus. Visual acuity measurements were not possible in 26 uncooperative patients. The visual acuity was 0.3 logMAR and over in 15 (31% and 1.0 logMAR and under in 12 (25% of the remaining of 48 eyes. Of a total of 28 eyes with strabismus, we were unable to measure visual acuity in 10 patients, and the visual acuities were 0.3 logMAR and over in 7 (39% and 1.0 logMAR and under in 5 (28% of the rest of the 18 patients. The mean visual acuity was significantly lower in the 8 of 14 patients with nystagmus whose visual acuity could be measured (1.25±0.45 logMAR than in both the patients without strabismus (0.44±0.59 logMAR and the patients with strabismus (0.66±0.56 logMAR (p=0.019 and p=0.015, respectively. Dis cus si on: Although strabismus is seen more often in childhood cataracts compared to general population, the presence of strabismus has no negative effect on visual acuity after cataract surgery, while nystagmus is the main factor limiting the visual outcome.

    Purpose of review To provide a comprehensive update of the pathogenesis, diagnostic imaging, treatments, and disease activity measurements of juvenile spondyloarthritis (JSpA). Recent findings Genetic and microbiome studies have provided new information regarding possible pathogenesis of JSpA. Recent work suggests that children with JSpA have decreased thresholds for pain in comparison to healthy children. Additionally, pain on physical examination and abnormalities on ultrasound of the entheses are not well correlated. Treatment guidelines for juvenile arthritis, including JSpA, were published by the American College of Rheumatology and are based on active joint count and presence of sacroiliitis. Recent studies have established the efficacy of tumor necrosis factor inhibitors in the symptomatic treatment of axial disease, though their efficacy for halting progression of structural damage is less clear. Newly developed disease activity measures for JSpA include the Juvenile Arthritis Disease Activity Score and the JSpA Disease Activity index. In comparison to other categories of juvenile arthritis, children with JSpA are less likely to attain and sustain inactive disease. Summary Further microbiome and genetic research may help elucidate JSpA pathogenesis. More randomized therapeutic trials are needed and the advent of new composite disease activity measurement tools will hopefully allow for the design of these greatly needed trials. PMID:26002028

    The radiation-induced cataract has been up to now considered as a quite rare pathology, needing high-dose radiations (beyond a dose threshold roughly estimated at 2 Grays to the lens) consisting mainly in head tumour radiotherapy complications. Several new studies on different exposed populations such as astronauts, japanese atomic bomb survivors, people undergoing X-ray examinations, Chernobyl accident 'liquidators' as well as data from animal experiments, suggest that dose threshold for detectable opacities as well as for clinical posterior sub-capsular cataract occurring, might be far lower than those previously assumed. Even the existence of a dose threshold is no longer an absolute certitude insofar as radiation-induced cataract pathogenesis might consist not really in a deterministic effect (direct tissue harmful effect, killing or seriously injuring a critical population of cells) as believed until now, but rather in a stochastic effect (genomic damage in target-cells, altered cell division, abnormal lens fiber cell differentiation). More practically, these new data may lead us to reconsider radioprotection of specifically exposed populations: mainly patients and workers. Regarding workers, labour legislation (lens equivalent dose limit of 150 mSv during 12 consecutive months) might be, in the medium term, reassessed downwards. (author)

    Hereditary hyperferritinemia cataract syndrome (HHCS) is a rare autosomal dominant hereditary disease, characterized by hyperferritinemia but with absence of body iron excess and early onset of bilateral cataracts. Although 5- to 20-fold increased serum ferritin concentrations have been reported in HHCS patients, data of ferritin levels in aqueous humor have not been obtained. We therefore aimed to investigate the ferritin levels in aqueous humor and serum and further present histological and ultrastructural data of the lens. During cataract extraction and intraocular lens implantation, aqueous humor and lens aspirate of a 37-year-old HHCS patient were obtained from both eyes. Ferritin levels in serum and aqueous humor were quantitatively analyzed via immunoassays in the HHCS patient and healthy control subjects (n = 6). Lens aspirate in HHCS was analyzed histologically and at the ultrastructural level. Further, genetic mutation screening by polymerase chain reaction and DNA sequencing in blood was performed. Serum ferritin levels in the control group were 142.2 ± 38.7 μg/L, whereas in the HHCS patient, this parameter was excessively increased (1086 μg/L). Analysis of ferritin in aqueous humor revealed 6.4 ± 3.8 μg/L in normal control subjects and 146.3 μg/L (OD) and 160.4 μg/L (OS) in the HHCS patient. DNA analysis detected a C>A mutation on position +18, a T>G mutation on position +22, a T>C mutation on position +24, and a T>G polymorphism on position +26 in the iron-responsive element of the light-chain ferritin (L-ferritin) gene. In the HHCS patient, a 23-fold (OD) to 25-fold (OS) increased aqueous humor ferritin level was detected. Therefore, the formation of bilateral cataract in HHCS is most likely a result of elevated aqueous humor ferritin. In addition, a novel mutation in this rare disease in the iron-responsive element of L-ferritin gene is reported.

    A retrospective review of 98 cases of complicated cataract surgery and/or delayed intraocular lens (IOL) dislocation examined the relationship between vitrectomy and cataract surgery complications. Nine (9.2%) of the 98 patients had a history of vitrectomy, before or after cataract surgery, and each had complicated cataract surgery. Six patients who underwent vitrectomy before cataract surgery experienced intraoperative complications. Three patients in whom vitrectomy was performed after uneventful cataract surgery subsequently had delayed IOL dislocation.

    Based upon biometric and statistical analysis of 163 eyes (26 mm or longer), it appears that high myopia cataract occur all the earlier as the eye is long; on average, these were operated on ten years earlier than cataracts in the general population. Extra-capsular extraction and intercapsular implantation were generally used. Pre and post-operative complications are remarkably rare for such abnormal eyes. After a mean period of 22 months, detachment of the retina was observed in 1.84% of patients and secondary capsulotomy performed in 8%. Because they prevent secondary capsular opacification and anterior vitreous propagation, it appears that such barrier-type implants should be systematically placed. Current large-diameter implants allow for vitreoretinal observation. Based upon this patient population, a formula for implant power calculation specific to high myopia has been elaborated. The desired degree of refraction varies with age and patient activity.

    Full Text Available PURPOSE: To report the visual outcomes and complications of congenital cataract surgery with primary intraocular lens implantation in microphthalmic eyes of children younger than 4 years of age. METHODS:This retrospective interventional case series included 14 microphthalmic eyes from 10 children who underwent congenital cataract surgery with primary intraocular lens implantation younger than 4 years of age. Seven patients had bilateral cataracts (11 eyes met the study's inclusion criteria and 3 patients had unilateral cataract. Patients' medical charts were reviewed to obtain information regarding the preoperative and postoperative ophthalmological examination. Main outcome measures were intraocular pressure (IOP, best-corrected visual acuity, and intraoperative and postoperative complications. RESULTS: Mean age at the time of surgery was 21.7 ± 2.9 months. Mean ocular axial length was 19.2 ± 0.9 mm. Mean preoperative IOP was 9.7 ± 1.7 mmHg and 10.3 ± 3.1 mmHg on final follow-up (P=0.18. There were no intraoperative complications. Two (15.4% eyes developed secondary visual axis opacification, of which only one needed to be reoperated due to significantly decreased vision (0.5 logMAR. Preoperative and postoperative best-corrected visual acuity was 2.09 ± 0.97 logMAR and 0.38 ± 0.08 logMAR in bilateral cases and 1.83 ± 1.04 logMAR and 0.42 ± 0.13 logMAR in unilateral cases, respectively. CONCLUSION: Primary intraocular lens implantation in congenital cataract surgery in microphthalmic eyes resulted in a significant best-corrected visual acuity improvement with no intraoperative complications and minimal postoperative complications.

    ·AIM: To determine the effect of metabolic syndrome on age-related cataract formation.·METHODS: We analyzed data for 2852 subjects [41.8%men and 58.2% women; mean(±SD) age, 52.9 ±13.9y],taken from the Korea National Health and Nutrition Examination Survey 2008. Metabolic syndrome was diagnosed by criteria proposed by the Joint Interim Societies. Cataract was diagnosed by using the Lens Opacities Classification System III. The association between metabolic syndrome and cataract was determined using age-adjusted and multivariable logistic regression analyses.· RESULTS: In multivariable analyses, men with metabolic syndrome had a 64% increased risk of nuclear cataract [odds ratio(OR), 1.64; 95% confidence interval(CI), 1.12-2.39]. Women with metabolic syndrome had a56% increased risk of cortical cataract(OR, 1.56; 95% CI,1.06-2.30). Men and women with metabolic syndrome had a 46%(OR, 1.46; 95% CI, 1.01-2.12) and 49%(OR,1.49; 95% CI, 1.07-2.08) increased risk of any cataract,respectively. The prevalence of nuclear and any cataract significantly increased with an increasing number of disturbed metabolic components in men, and prevalence of all types of cataracts increased in women. Men using hypoglycemic medication had an increased risk of nuclear(OR, 2.62; 95% CI, 1.41-4.86) and any(OR, 2.27;95% CI, 1.14-4.51) cataract, and women using antidyslipidemia medication had an increased risk of cortical(OR, 2.18; 95% CI, 1.12-4.24) and any(OR, 2.21;95% CI, 1.14-4.26) cataract.·CONCLUSION: Metabolic syndrome and its components,such as abdominal obesity, high blood pressure, andimpaired fasting glucose, are associated with age-related cataract formation in the Korean population.

  9. Molecular genetics of congenital nuclear cataract.

    A cataract is defined as opacification of the normally transparent crystalline lens. Congenital cataract (CC) is a type of cataract that presents at birth or during early childhood. CC is one of the most common causes of visual impairment or blindness in children worldwide. Approximately 50% of all CC cases may have a genetic cause which is quite heterogeneous. CC occurs in a variety of morphologic configurations, including polar/subcapsular, nuclear, lamellar, sutural, cortical, membranous/capsular and complete. Nuclear cataract refers to the opacification limited to the embryonic and/or fetal nuclei of the lens. Although congenital nuclear cataract can be caused by multiple factors, genetic mutation remains to be the most common cause. It can be inherited in one of the three patterns: autosomal dominant, autosomal recessive, or X-linked transmission. Autosomal dominant inheritance is the most frequent mode with high penetrance. There may be no obvious correlation between the genotype and phenotype of congenital nuclear cataract. Animal models have been established to study the pathogenesis of congenital nuclear cataract and to identify candidate genes. In this review, we highlight identified genetic mutations that account for congenital nuclear cataract. Our review may be helpful for genetic counseling and prenatal diagnosis.

    2010-01-01

    We here in report a case of bilateral endogenous endophthalmitis caused by Pantoea agglomerans (P. agglomerans) in a patient who had interstitial lung disease and was treated with oral corticosteroids. A 72-year-old man presented with decreased visual acuity in both eyes nine days after he received oral corticosteroids. He had marked uveitis, cataracts, and vitreous opacities. Cultures were taken of blood, aqueous humor, and vitreous. We initially suspected a fungal etiology and treated him with antifungal drugs; however, the intraocular disease progressed without improvement. Vitreous culture was positive for P. agglomerans. The patient underwent pars plana vitrectomy with cataract surgery bilaterally, followed by a 2-week course of antibiotics. The final visual acuity was 20/25 in the right eye and 20/200 in the left eye. This is the first report of bilateral endogenous endophthalmitis caused by P. agglomerans in Korea; it is also the first case reported outside of the United States. PMID:20714391

    Introduction. Previous cataract surgery studies assumed that first-eye predicted and observed postoperative refractions are equally important for predicting second-eye postoperative refraction. Methods. In a retrospective analysis of 173 patients having bilateral sequential phacoemulsification, multivariable linear regression was used to predict the second-eye postoperative refraction based on refractions predicted by the SRK-T formula for both eyes, the first-eye postoperative refraction, and the difference in IOL selected between eyes. Results. The first-eye observed postoperative refraction was an independent predictor of the second eye postoperative refraction (P refraction. Compared with the SRK-T formula, this model reduced the root-mean-squared (RMS) error of the predicted refraction by 11.3%. Conclusions. The first-eye postoperative refraction is an independent predictor of the second-eye postoperative refraction. The first-eye predicted refraction is less important. These findings may be due to interocular symmetry.

Early diagnosis and prompt surgical intervention is critical to prevent irreversible amblyopia. Thorough ocular evaluation, including the onset, duration, and morphology of a cataract, is essential to determine the timing for surgical intervention. Detailed assessment of the general health of the child, preferably in conjunction with a pediatrician, is helpful to rule out any associated systemic condition. Although pediatric cataracts have a diverse etiology, with the majority being idiopathic, genetic counseling and molecular testing should be undertaken with the help of a genetic counselor and/or geneticist in cases of hereditary cataracts. Advancement in surgical techniques and methods of optical rehabilitation has substantially improved the functional and anatomic outcomes of pediatric cataract surgeries in recent years. However, the phenomenon of refractive growth and the process of emmetropization have continued to puzzle pediatric ophthalmologists and highlight the need for future prospective studies. Posterior capsule opacification and secondary glaucoma are still the major postoperative complications necessitating long-term surveillance in children undergoing cataract surgery early in life. Successful management of pediatric cataracts depends on individualized care and experienced teamwork. We reviewed the etiology, preoperative evaluation including biometry, choice of intraocular lens, surgical techniques, and recent developments in the field of childhood cataract.

    The prevalence and the distribution characteristics of corneal astigmatism (CA) and anterior segment biometry before surgery in Chinese congenital cataract (CC) patients are not completely understood. This study involved 400 CC patients from the Zhongshan Ophthalmic Center enrolled from February 2011 to August 2015. Data on CA, keratometry, central corneal thickness (CCT) and anterior chamber depth (ACD) were measured by the Pentacam Scheimpflug System. The mean age of patients was 54.27 months, and the ratio of boys to girls was 1.53:1. The mean CA was 2.03 diopters (D), and 39.25% of subjects had CA values ≥2 D. The most frequent (71.8%) diagnosis was with-the-rule astigmatism. Oblique astigmatism was present in 16.2% of cases, and 12% of cases had against-the-rule astigmatism. The mean keratometry measurement of cataractous eyes in bilateral patients was significantly larger than that in unilateral patients. Girls had a larger mean keratometry but a thinner CCT than did boys. The CA, CCT, and ACD of cataractous eyes were significantly larger than those of non-cataractous eyes in unilateral patients. The CA, mean keratometry, CCT, and ACD in CC patients varied with age, gender, and laterality. Fully understanding these characteristics may help inform guidelines and treatment decisions in CC patients.

    Couching for cataract is one of the most ancient surgical procedures. Maharshi Sushruta, an ancient Indian surgeon, first described the procedure around 600 BCE in Sushruta Samhita. The procedure, also known as jin pi shu in Mandarin, was introduced to China via the Silk Road during the late West Han Dynasty (206 BCE-9 CE), and it spread throughout China during the Tang Dynasty (618-907 CE). As the procedure was combined with the Chinese concept of acupuncture, jin pi shu was integrated into Chinese medical practice until the founding of the Republic of China in 1911. The government of the Republic of China considered jin pi shu to be unscientific. In 1949, the Communists established the People's Republic of China. Jin pi shu was revitalized by Chairman Mao Zedong (1893-1976), who thought that traditional Chinese medicine, including jin pi shu, was a great treasure. After his death and the opening of China to the external world, many Chinese ophthalmologists pointed out that jin pi shu had relatively high complications and a low success rate, compared to various modern techniques for cataract surgery. This procedure is gradually fading away in China. The use of jin pi shu reflects the history, culture, and political transformation of China. Published by Elsevier Inc.

    Full Text Available The prevalence of blindness among children in different regions varies from 0.2/1000 children to over 1.5/1000 children with a global figure estimated at 0.7/1000. This means that there are an estimated 1.4 million blind children worldwide.1 The proportion of blindness in children due to cataract varies considerably between regions from 10%-30% with a global average estimated at 14%, giving 190,000 children blind from cataract. 2 While the magnitude of childhood cataracts varies from place to place, it is a priority within all blindness control programmes for children. Children who are blind have to overcome a lifetime of emotional, social and economic difficulties which affect the child, the family and society.3 Loss of vision in children influences their education, employment and social life. The numbers blind with cataract do not reflect the years of disability and lost quality of life. Childhood blindness is second only to adult cataract as a cause of blind-person years. Approximately 70 million blind-person years are caused by childhood blindness of which about 10 million blind-person years (14% is due to childhood cataract. Timely recognition and intervention can eliminate blind-years due to childhood cataract, as the condition is treatable.

    Purpose. Dupuytren disease is an inherited proliferative and progressive connective disease. Ectopic disease may, however, be located distant from the palmar fascia. 
Methods. Case report and review of the literature. 
Results. We describe a case of symmetric bilateral posterior subcapsular cataracts associated with symmetric bilateral Dupuytren disease and symmetric bilateral Ledderhose disease in a 56-year-old Caucasian man. His medical history was negative for glucocorticoids intake, diabetes, and exposure to radiation. Serum transforming growth factor β (TGF-β)1 concentration has been evaluated and was found to be almost double compared to the controls. 
Conclusions. We speculate that the TGF-β plays an important role for ocular and connective tissue disorders.

    To analyze the expression of 78 kDa glucose-regulated protein (GRP78) and activating transcription factor 6 (ATF6), 2 factors in the unfolded protein response (UPR), in age-related and diabetes-associated cataract. Universidad Autónoma de Aguascalientes, Aguascalientes, México. Experimental study. The qualitative and quantitative expression of GRP78 and ATF6 were measured in surgical samples from 11 senile cataracts, 9 diabetic-associated cataracts, and 3 normal lenses. Both proteins were detected by immunofluorescence and immunogold-conjugated antibodies. Quantitative morphometry was used to analyze the differences in GRP78 and ATF6 between samples. The Mann-Whitney test was used for statistical analysis. Scanning electron microscopy showed the characteristic organization of fibers in normal lenses with regular alignment and interdigitation between them. On the other hand, lenses from eyes with senile or diabetic cataract showed the same pattern of misalignment and disorganization of the fibers. Both proteins were detected through immunofluorescence in senile and diabetic cataracts, but not in normal lenses. Immunogold-conjugated antibodies and transmission electron microscopy showed that GRP78 and ATF6 grains were 30% higher and 35% higher, respectively, in diabetic cataracts than in senile cataracts (P<.05). These data show for the first time in humans that GRP78 and ATF6 are present in lens fibers of senile cataracts and diabetic cataracts, establishing that the UPR may be important in the process of cataractogenesis.

    Full Text Available Introduction. Cataracts cause about 50% of world blindness. There is little likelihood of effective prevention becoming available in the next few years and so the only treatment will remain surgical. For many of the other major causes of world blindness, like trachoma, xerophthalmia and onchocerciasis, the remedy is community-based, not hospital-based, and requires prevention rather than treatment. The prevalence of blinding cataract will only increase as people live longer, so cataract will continue to be, by far, the most important treatable cause of blindness.

    Full Text Available In many countries, the number of cataract operations performed is inadequate to deal even with the people who have newly become blind from cataract, let alone those who are already blind or visually impaired. There is, therefore, a backlog of cases needing surgery. This could be due to low surgical capacity (people are on a waiting list or to a lack of demand for cataract surgery (people haven’t come forward for the services they need and there is therefore no waiting list.

    Administration of acetaminophen (ACP, 3.0 mmol/kg, i.p.) to beta-naphthoflavone-induced C57 BL/6 mice led to the formation of bilateral cataracts within 8 hr with a 71% incidence. The hepatic glutathione (GSH) levels were reduced 99% and lenticular GSH levels reduced 42% in cataractous mice. Cataract formation was completely prevented by the co-administration of the L-cysteine prodrugs 2(R, S)-methylthiazolidine-4(R)-carboxylic acid (MTCA) and 2(R, S)-n-propylthiazolidine-4(R)-carboxylic acid (PTCA) in two divided i.p. doses totaling 4.5 mmol/kg. 2-Oxo-L-thiazolidine-4-carboxylic acid (OTCA) was nearly equipotent, yielding only one cataract in 16 mice, but D-ribose-L-cysteine (RibCys, 5/16) and N-acetyl-L-cysteine (NAC, 9/14) were much less effective. Hepatic and lenticular GSH were maintained at near normal levels by MTCA, PTCA and OTCA. These results suggest that maintenance of adequate cellular GSH levels in the presence of ACP protects against cataract induction.

The role of the following factors on the development of glaucoma after CCS including age at surgery, gender, laterality of the cataract, IOL implantation, congenital ocular anomalies, intra- and postoperative complications, length of follow-up, central corneal thickness (CCT as well as the effect of the age of onset, time to development of glaucoma, and response to treatment were evaluated. Results: Overall, 161 eyes of 96 patients were included in this study of which 28 eyes developed glaucoma. Incidence of glaucoma was 17.4%. Mean±SD age at surgery was 9.3±6.9 (range, 1-24 months in glaucomatous and 40.4±41.1 (range, 1 m-13.6 year months in non-glaucomatous group (p<0.001. All glaucoma patients had the operation under two years of age. In group 1, 9 (60% and in group 2, 24 (30% patients were female (p=0.001. In group 1, 17 eyes (60.7% and in the group 2, 41 eyes (30.8% were aphakic (p=0.001. Mean time to diagnosis of glaucoma was 111.2 days (range 30-1200 days. Mean follow-up time was 3.1 years (range, 1-6 years. In 22 (78.6% eyes glaucoma was diagnosed within six months after surgery. Glaucoma was controlled with medications in 23 eyes (82% and with surgery in five eyes. Conclusion: In this study the incidence of glaucoma after CCS was 17.4% over a follow-up period of six years. Younger age at the time of lensectomy increases the risk of secondary glaucoma. IOL implantation may protect against glaucoma. Female gender was affected more than male.

    2014-03-01

    Hyperferritinemia and bilateral cataracts are features of the rare hereditary hyperferritinemia cataract syndrome (HHCS; OMIM #600886). HHCS is an autosomal dominant condition caused by mutations which increase expression of the ferritin light polypeptide (FTL) gene. We report a patient with HHCS who was misdiagnosed and treated as having hemochromatosis, in whom a heterozygous c.-160A>G mutation was identified in the iron responsive element (IRE) of FTL, causing ferritin synthesis in the absence of iron overload. This report demonstrates the need for clinical awareness of HHCS as a cause of hyperferritinemia in the absence of iron overload and provides a possible diagnostic schema. © 2014 The Authors.

    We describe the smallest incision cataract removal technique, Microphakonit, in which bimanual phacoemulsification can be performed with a 0.7 mm phaco tip and 0.7 mm irrigating chopper. Cortical removal is done using 22 gauge or 0.7 mm irrigation/aspiration instruments. The technique was used for 25 adult human eyes with grade 2 nuclear sclerosis and 5 adult human eyes with grade 3 nuclear sclerosis. None of these patients were noted to have intraoperative complications. One eye with grade 3 nuclear sclerosis had mild, central striate keratopathy postoperatively. Six months after surgery, 92% of the patients had a best corrected visual acuity (BCVA) of 20/20 and 96% had >/=20/25.

    2007-04-01

    Full Text Available Abstract Background Despite recommendations for greater use of second-eye cataract surgery and the bilateral progression of the disease, there is a substantial proportion of unmet need for this treatment. Few studies have explored the factors associated with second-eye cataract surgery utilisation. The objective of our study was to estimate the proportion of second-eye cataract surgery, evaluate its time-trend, and explore differences in utilisation by patients' gender, age, and region of residence. Methods All senile cataract surgeries performed between 1999 and 2002 in the public health system of Catalonia (Spain were obtained from the Minimum Data Set. The proportion of second-eye surgery from November 2000 to December 2002 was calculated. The time-trend of this proportion was characterised through linear regression models with the logarithmic transformation of time. Results The proportion of second-eye surgery was 30.0% and showed an increasing trend from 24.8% (95% Confidence Interval [CI] 21.6; 26.1 in November 2000 to 31.8% (95% CI 31.4; 33.6 in December 2002. This proportion was 1.9% (95% CI 0.9; 2.9 higher in women (p Conclusion We predict greater utilization of second-eye surgery in patients aged 70 to 79 years and in women. A greater increase in the utilisation rates of second-eye surgery is expected in the regions with lower proportions and in older patients. The observed trend suggests that there will be a substantial proportion of unmet need for bilateral surgery.

  4. Cataract Surgery in Anterior Megalophthalmos: A Review

    Science.gov (United States)

    GALVIS, Virgilio; TELLO, Alejandro; M. RANGEL, Carlos

    2015-01-01

    Anterior megalophthalmos is characterized by megalocornea associated with a very broad anterior chamber and ciliary ring elongation. It is also called X-linked megalocornea. It is accompanied by early development of cataracts, zonular anomalies, and, rarely, vitreoretinal disorders. Subluxation of a cataract can occur in cataract surgery because of zonular weakness. In addition, in most patients, standard intraocular lens (IOL) decentration is a risk because of the enlarged sulcus and capsular bag. These unique circumstances make cataract surgery challenging. To date, several approaches have been developed. Implantation of a retropupillary iris-claw aphakic intraocular lens may be a good option because it is easier than suturing the IOL and can have better and more stable anatomic and visual outcomes, compared to other techniques.

  6. Intraocular lens employed for cataract surgery

    Science.gov (United States)

    Roszkowska, A. M.; Torrisi, L.

    2014-04-01

    The aim of this paper is to illustrate the techniques of cataract surgery with implantation of intraocular lenses and some physical properties of the used materials. The new technology, coupled with extensive experience and the studied cases, permits to increase the standardization and accuracy of the engravings, by reducing the use and handling of surgical instruments inside the eye. At present it is possible to replace the cataract with crystalline lenses based on biopolymers such as PMMA, silicone, acrylic hydrophilic and hydrophobic acrylic. These materials are increasingly able to replace the natural lens and to ensure the fully functional of the eye. The role of femtosecond lasers in cataract surgery, to assist or replace several aspects of the manual cataract surgery, are discussed.

    2015-01-01

    Full Text Available Background: Acute bilateral extradural hematoma is a rare presentation of head trauma injury. In sporadic cases, they represent 0.5-10% of all extradural hematomas. However, higher mortality rates have been reported in previous series. Case Description: The authors described the case of a 28-year-old male presenting head injury, comatose, Glasgow Coma Scale of 6, anisocoric pupils without puppilary light reflex. Computed tomography showed asymmetric bilateral epidural hematomas, effacement of the lateral ventricles and sulci, midline shift and a bilateral skull fracture reaching the vertex. Surgical evacuation was performed with simultaneous hematoma drainage. Patient was discharged on the 29 th postoperative day with no neurological deficit. Conclusion: The correct approach on bilateral epidural hematomas depends on the volume, moment of diagnosis, and neurological deficit level. Simultaneous drainage of bilateral hematomas has been demonstrated to be an effective technique for it, which soon decreases the intracranial pressure and promotes an efficient resolution to the neurological damage.

    Full Text Available Corneal edema, hyphema, lens dislocation, iris atrophy, cataract and glaucoma cases due to bee sting are frequently reported. Optic neuropathy developing after a bee sting is rarely reported. A 46-year-old man applied to our clinic with visual loss. He had a history of transient loss of consciousness and bilateral severe visual loss after a bee sting 10 days ago. His first diagnosis was myocardial infarction and coronary angiography was applied in a private hospital; the angiography was found normal. In our clinic, his best-corrected visual acuity was 0.5 in the right eye and 0.7 in the left eye. The diagnosis was bilateral optic neuritis, and 64 mg/day oral methylprednisolone treatment was applied. Visual acuity improved to 1.0 in both eyes 39 days later. Optic neuritis due to bee sting is a rare case that can cause severe visual loss and responds well to systemic corticosteroid treatment. (Turk J Ophthalmol 2014; 44: 72-4

  14. Cataract blindness in the developing world: is there a solution?

    Science.gov (United States)

    Isaacs, Robert; Ram, Jagat; Apple, David

    2004-01-01

    Cataracts are the leading cause of blindness worldwide, accounting for half of the world's 40 million blind. The majority of the world's 20 million cataract blind live in the developing world. About 5 million new cases of cataract blindness occur each year. Only a small percentage of persons in the Third World who develop cataracts receive cataract surgery. Cataract blindness causes severe economic and social problems in these countries. Because of increased longevity and population growth in the Third World, the number of untreated cataract cases is escalating rapidly. Governmental, non-governmental and service club organizations have put extraordinary effort and resources into reversing the trend of increasing cataract blindness, but much work still needs to be done. Current surgical methods used in the Third World have not yet succeeded in reducing the backlog of cataracts, due in part to either their prohibitive cost or poor results. Extra capsular cataract extraction (ECCE) with placement of a posterior chamber intraocular lens (PC-IOL) is the hope for preferred method of treatment. This paper discusses a largely overlooked method of cataract surgery which may be an additional, cost-effective and efficacious means of providing good sight rehabilitation. Combining intracapsular cataract extraction, currently the most common method used in the rural developing world, with anterior chamber intraocular lens implantation (ICCE AC-IOL), may prove effective in reducing the cataract backlog in developing countries.

    2004-01-01

    Hyperferritinemia-cataract syndrome (HHCS) is a dominant disorder characterized by high serum ferritin and early onset of bilateral cataract. The disorder is caused by mutations in the iron-responsive element (IRE) of l-ferritin, which disrupt the postranscriptional control of l-ferritin synthesis. Here, we report a new (C>G) mutation which affects base 29 in the loop (c.-169C>G), previously unrecognized as essential for the stem loop stability. The mutation was identified in two members of an Italian family. Computer modeling and electrophoretic mobility shift assay (EMSA) confirm a decreased affinity of the C29G IRE for IRPs control proteins.

    2016-04-01

    Cataract is the leading cause of blindness worldwide and accounts for approximately half of all forms of vision loss. Currently, the only way to treat cataracts is by surgery. However, with an ageing population, the demand for surgery and the need for cost effective alternative solutions grows exponentially. To reduce the need for cataract surgery, alternative medical therapies to delay cataracts are urgently required. However, given the difficulty in accessing human cataract lenses, investigating the process of cataract formation and testing the efficacy of potential therapies in humans is problematic. Therefore, researchers have looked to create suitable animal models of cataractogenesis to identify therapeutic options. This review will provide an overview of the cataract specific changes previously reported in human cataract lenses, before focussing on the specific changes that occur in age related nuclear (ARN) cataract, the most common form of cataract in humans. This will be followed by a discussion of a range of existing animal cataract models and their respective suitability for mimicking the processes associated with the development of ARN cataract, and therefore their utility as models to test anti-cataract therapies for future use in humans.

  1. Echinoderms have bilateral tendencies.

    2012-01-01

    Echinoderms take many forms of symmetry. Pentameral symmetry is the major form and the other forms are derived from it. However, the ancestors of echinoderms, which originated from Cambrian period, were believed to be bilaterians. Echinoderm larvae are bilateral during their early development. During embryonic development of starfish and sea urchins, the position and the developmental sequence of each arm are fixed, implying an auxological anterior/posterior axis. Starfish also possess the Hox gene cluster, which controls symmetrical development. Overall, echinoderms are thought to have a bilateral developmental mechanism and process. In this article, we focused on adult starfish behaviors to corroborate its bilateral tendency. We weighed their central disk and each arm to measure the position of the center of gravity. We then studied their turning-over behavior, crawling behavior and fleeing behavior statistically to obtain the center of frequency of each behavior. By joining the center of gravity and each center of frequency, we obtained three behavioral symmetric planes. These behavioral bilateral tendencies might be related to the A/P axis during the embryonic development of the starfish. It is very likely that the adult starfish is, to some extent, bilaterian because it displays some bilateral propensity and has a definite behavioral symmetric plane. The remainder of bilateral symmetry may have benefited echinoderms during their evolution from the Cambrian period to the present.

    To determine whether combined cataract surgery with endoscopic laser cycloablation produces less inflammation than cataract surgery combined with a filtering procedure. Taylor Regional Hospital (surgeries) and EyeSight Associates (examinations), Warner Robins, Georgia, USA. A randomized prospective study was conducted of 58 eyes of 58 patients comparing endoscopic laser cycloablation performed through a cataract incision at the time of cataract surgery with combined trabeculectomy and cataract surgery. Mean follow-up was 2 years. At the final available visit, 30% of endoscopic laser patients achieved intraocular pressure control (below 19 mm Hg) without medication and 65% with medication. Forty percent of trabeculectomy patients achieved control without medication and 52% with medication. Four endoscopic laser patients (14%) and 3 trabeculectomy patients (10%) were considered treatment failures (required additional surgical intervention). Endoscopic laser cycloablation performed through a cataract incision was a reasonably safe and effective alternative to combined cataract and trabeculectomy surgery, providing an option for cataract patients who have glaucoma requiring surgical intervention.

    To evaluate the difference between target and actual refraction after phacoemulsification and intraocular lens implantation at an academic teaching institution's Comprehensive Ophthalmology Service. Retrospective study. We examined 1275 eye surgeries for this study. All consecutive cataract surgeries were included if they were performed by an attending or resident surgeon from January through December 2010. Postoperative refractions were compared with preoperative target refractions. Patients were excluded if they did not have a preoperative target refraction documented or if they did not have a recorded postoperative manifest refraction within 90 days. The main outcome measure was percentage of cases achieving a postoperative spherical equivalent ± 1.0 diopter (D) of target spherical equivalent. We performed 1368 cataract surgeries from January through December of 2010. Of these, 1275 (93%) had sufficient information for analysis. Of the included cases, 94% (1196 of 1275) achieved ± 1.0 D of target refraction by 90 days after cataract surgery. This paper establishes a new benchmark for a teaching hospital, where 94% of patients achieved within 1.0 D of target refraction after cataract surgery. The refractive outcomes after cataract surgery at this academic teaching institution were higher than average international benchmarks. Copyright © 2014 American Academy of Ophthalmology.

    Full Text Available Aim: Juvenile idiopathic arthritis (JIA associated uveitis is one of the most common causes of visual morbidity in children. We report the systemic, clinical and investigational features of a cohort of all cases of JIA associated uveitis seen at our referral uveitis clinic between 1988 and 2004. Study Design: Retrospective case series Materials and Methods: All patients of JIA seen at the uveitis clinic of tertiary eye care hospital, between 1988 and 2004 with minimum follow up of 3 months were included. Complete history and ophthalmic evaluation and findings on each visit were noted. Ocular complications were identified and recorded. Results of laboratory investigations and diagnostic as well as therapeutic procedures were analyzed. A rheumatologist managed systemic status. Results: There were 40 patients (64 eyes with JIA. Thirty four patients (85% had pauciarticular type and 6 patients (15% had polyarticular type of JIA. Complicated cataract and band shaped keratopathy were seen in 38 eyes (63% and 37 eyes (62% respectively. Twenty-two patients (17 bilateral and 5 unilateral were treated with immunosuppressives and in 19 of these patients, the disease went into remission. Twenty-three eyes (38% had improvement in visual acuity while in 27 eyes (45%, the vision remained stable and in 10 eyes (17%, vision deteriorated despite therapy. Conclusion: In India, JIA associated uveitis commonly presented in pauciarticular type with preponderance in males. Rheumatoid arthritis factor and anti nuclear antibodies were not as common as compared to the western population. Among long-term treatment options, immunosuppressives are a better choice. Ocular surgery was performed when mandatory for visual rehabilitation.

    This article describes common forensic evaluations requested of juvenile court mental health evaluators. There has been a legal shift toward criminalization of juvenile court, with a greater emphasis on rights, abandonment of the rehabilitative model, and greater movement of adolescents into the adult criminal court. A resulting shift has been the redefinition of juvenile court forensic evaluations toward the specificity of adult forensic work. The challenge for evaluators is to refine their knowledge of the forensic standards and bring knowledge of development, assessment, and diagnosis in juveniles and interview techniques appropriate to juveniles to improve the evaluation and forensic reports.

  10. Acid phosphatase and lipid peroxidation in human cataractous lens epithelium

    Directory of Open Access Journals (Sweden)

    Vasavada Abhay

    1993-01-01

    Full Text Available The anterior lens epithelial cells undergo a variety of degenerative and proliferative changes during cataract formation. Acid phosphatase is primarily responsible for tissue regeneration and tissue repair. The lipid hydroperoxides that are obtained by lipid peroxidation of polysaturated or unsaturated fatty acids bring about deterioration of biological membranes at cellular and tissue levels. Acid phosphatase and lipid peroxidation activities were studied on the lens epithelial cells of nuclear cataract, posterior subcapsular cataract, mature cataract, and mixed cataract. Of these, mature cataractous lens epithelium showed maximum activity for acid phosphatase (516.83 moles of p-nitrophenol released/g lens epithelium and maximum levels of lipid peroxidation (86.29 O.D./min/g lens epithelium. In contrast, mixed cataractous lens epithelium showed minimum activity of acid phosphatase (222.61 moles of p-nitrophenol released/g lens epithelium and minimum levels of lipid peroxidation (54.23 O.D./min/g lens epithelium. From our study, we correlated the maximum activity of acid phosphatase in mature cataractous lens epithelium with the increased areas of superimposed cells associated with the formation of mature cataract. Likewise, the maximum levels of lipid peroxidation in mature cataractous lens epithelium was correlated with increased permeability of the plasma membrane. Conversely, the minimum levels of lipid peroxidation in mixed cataractous lens epithelium makes us presume that factors other than lipid peroxidation may also account for the formation of mixed type of cataract.

    Juvenile polyposis syndrome is a rare autosomal dominant syndrome characterized by multiple distinct juvenile polyps in the gastrointestinal tract and an increased risk of colorectal cancer.The cumulative life-time risk of colorectal cancer is 39% and the relative risk is 34.Juvenile polyps have a distinctive histology characterized by an abundance of edematous lamina propria with inflammatory cells and cystically dilated glands lined by cuboidal to columnar epithelium with reactive changes.Clinically, juvenile polyposis syndrome is defined by the presence of 5 or more juvenile polyps in the colorectum,juvenile polyps throughout the gastrointestinal tract or any number of juvenile polyps and a positive family history of juvenile polyposis.In about 50%-60% of patients diagnosed with juvenile polyposis syndrome a germline mutation in the SMAD4 or BMPR1A gene is found.Both genes play a role in the BMP/TGF-beta signalling pathway.It has been suggested that cancer in juvenile polyposis may develop through the so-alled "landscaper mechanism" where an abnormal stromal environment leads to neoplastic transformation of the adjacent epithelium and in the end invasive carcinoma.Recognition of this rare disorder is important for patients and their families with regard to treatment,follow-up and screening of at risk individuals.Each clinician confronted with the diagnosis of a juvenile polyp should therefore consider the possibility of juvenile polyposis syndrome.In addition, juvenile polyposis syndrome provides a unique model to study colorectal cancer pathogenesis in general and gives insight in the molecular genetic basis of cancer. This review discusses clinical manifestations, genetics, pathogenesis and management of juvenile polyposis syndrome.

    Methylphenidate hydrochloride (Ritalin) is the drug of choice for attention deficit hyperactivity disorder (ADHD). However, an association of Ritalin with glaucoma has been reported. We report a case of Ritalin-associated cataract and glaucoma. A 10-year-old boy was diagnosed with ADHD and had received methylphenidate hydrochloride, 60 mg/day for 2 years. He presented with blurred vision. Best-corrected visual acuity was 6/60 in both eyes. Ocular examinations revealed intraocular pressure (IOP) of 30 mmHg under medication, dense posterior subcapsular opacity of lens, pale disc with advanced cupping, and marked constriction of visual field. Despite maximal anti-glaucomatous medication, IOP still could not be controlled. The patient then received combined cataract and glaucoma surgery. Visual acuity improved and IOP was within normal limits in both eyes postoperatively. Large dose of methylphenidate may cause cataract and glaucoma. The mechanism remains unclear.

    Age-related cataracts are mainly caused by life-long accumulation of oxidative stress on the lens fibres. Symptoms include reduced visual acuity, requiring more light for reading, and glare. The only treatment that provides a cure for cataracts is surgery. Phacoemulsification represents the preferred method of lens removal. It involves fragmentation of the lens using ultrasound and insertion of an artificial intraocular lens. The preoperative assessment the general practitioner provides to surgeon and anesthesia team has an important share in the low complication rate of the procedure in the event of co-existing systemic disease. Growing patient expectation for spectacle independence following cataract surgery is met to some extent using techniques for astigmatism control and presbyo-pia-correcting intraocular lenses.

    Full Text Available La escleritis posterior es un proceso inflamatorio de la parte posterior de la esclera. Su prevalencia es muy baja y el diagnóstico puede resultar complicado por la ausencia de signos oculares externos. Es más frecuente en mujeres. Cuando aparece en pacientes jóvenes no suele tener otras patologías asociadas, pero en mayores de 55 años hasta un tercio de los casos tienen relación con alguna enfermedad sistémica, sobre todo la artritis reumatoide. El diagnóstico de esta patología puede requerir un abordaje multidisciplinar y la colaboración de oftalmólogos con neurólogos, internistas o reumatólogos. En este artículo se describe un caso de escleritis posterior bilateral idiopática.Posterior scleritis is an inflammatory process of the posterior part of the sclera.

    To evaluate the phacoemulsification and intraocular lens implantation in patients with sensory exotropia subsequent to senile cataract. The authors prospectively studied the role of phacoemulsification and intraocular lens implantation on 25 patients by observing visual acuity, ocular alignment, binocular vision and diplopia pre-, 1 month post- and 3 months post-operation. The patients underwent follow-up for three months. Postoperatively, one patient had a corrected visual acuity of 20/50, and 24 patients had 20/40 or better. The ocular alignment, binocular vision and diplopia were resolved spontaneously. Phacoemulsification and intraocular lens implantation performed together is effective on sensory exotropia subsequent to senile cataract.

    Full Text Available PURPOSE: To compare the intraoperative safety of two techniques of capsulorhexis for intumescent white cataracts: traditional one-stage continuous curvilinear capsulorhexis and two-stage continuous curvilinear capsulorhexis. METHODS: This prospective comparative randomized study included two groups: the 1-CCC group (11 patients received traditional one-stage continuous curvilinear capsulorhexis with 5-6 mm diameter, and the 2-CCC (13 patients group received a deliberately small continuous curvilinear capsulorhexis that was secondarily enlarged, or a two-stage continuous curvilinear capsulorhexis. Patients were stratified according to cataract subset, which was characterized echographically. Six patients were considered as type 1, fifteen as type 2 and three as type 3. Type 1 included intumescent white cataracts with cortex liquefaction and extensive internal acoustic reflections, type 2 included white cataracts with voluminous nuclei, a small amount of whitish solid cortex, and minimal internal acoustic reflections, and type 3 included white cataracts with fibrous anterior capsules and few internal echo spikes. RESULTS: With the one-stage technique, 46.15% of patients had leakage of the liquefied cortex; in addition, the surgeon perceived high intracapsular pressure in 61.53% of cases. Anterior capsule tears occurred in 23.07% of cases, discontinuity of capsulorhexis in 30.79% of cases and no posterior capsular rupture occurred. With the two-stage technique, leakage of the liquefied cortex occurred in 45.45% of cases; additionally, the surgeon perceived high intracapsular pressure in 36.36% of cases. No anterior capsule tears, discontinuity of capsulorhexis or posterior capsular rupture occurred. Considering each cataract subset, there was a higher incidence of leakage for type 2 as compared to types 1 and 3. CONCLUSIONS: Two-stage continuous curvilinear capsulorhexis helps prevent unexpected radial tears of the initial capsulotomy from high

    The optimal management of cataract in the glaucoma patient must be constantly updated as advances in both subspecialties impact the surgical decision. The primary considerations at this time include combining the procedures as opposed to sequential operations and optimizing the effectiveness of the operations while reducing complications. Recent findings would certainly suggest an individualized approach based not only on the glaucoma and cataract condition of the patient but also on the experience of the surgeon with varied techniques. Further time and research are required to determine whether certain approaches or techniques will become more universally adopted. At present, there certainly is support for a variety of approaches.

    Full Text Available Morgagni hernia is a rare congenital diaphragmatic hernia. It is seen rarely bilaterally. Patients are usually asymptomatic. Therefore, diagnosis may be delayed until adulthood. Significant morbidity can occur in case complications arise and diagnosis is delayed. The patient, a 74 year-old female, presented in this article, was admitted to the emergency department with abdominal pain, vomiting, and shortness of breath. The plain abdominal radiograph of the patient revealed bowel obstruction and suspicious appearence in favor of the diaphragmatic hernia on both sides of the sternum. Computed tomography revealed bilaterally incarcerated Morgagni hernia with strangulated omentum in the right side of the sternum and a part of colon in the left side of sternum. Incarcerated organs were withdrawn to peritoneal cavity and defects of hernia were sutured primarily on laparatomy. Because bilateral incarcerated Morgagni hernia can be seen rarely, this case was reported.

    Osteomas are the most common benign osteoclastic tumours of the paranasal sinuses. However, nasal cavity and turbinate osteomas are extremely rare. Only nine middle turbinate, three inferior turbinate and one inferior turbinate osteoma cases have been reported to date. The present case report describes the management and follow-up of symptomatic bilateral inferior turbinate osteoma. A 60-year-old female presented with symptoms of bilateral nasal obstruction and right-sided epiphora. Radiological investigation found hypertrophic bony changes involving both inferior turbinates. The patient was managed successfully by endoscopic inferior turbinectomies in order to achieve a patent airway, with no further recurrence of tumour after 3 months postoperatively. To the best of our knowledge, this is the first reported case of bilateral inferior turbinate osteoma. We describe a safe and minimally invasive method of tumour resection, which has a better cosmetic outcome compared with other approaches. PMID:27534890

    Cataract is the first blinding eye disease in the world and China. However, due to various reasons, cataract surgery rate (CSR) in China is much lower than in developed countries and even some developing countries. Properly and standardized training of cataract surgery for ophthalmologists from primary hospital and young eye doctors is one of the key point to improve CSR. For above, we had explored actively to establish an appropriate and suitable training model of cataract surgery. Ophthalmologist in primary hospital can provide high quality medical services to cataract patients in accordance with their own conditions after training and promote the sustainable development of blindness prevention work.

    In order to clarify the role of tryptophan in the patogenesis of senile cataract, we have studied the serum total and free levels of tryptophan in cataract patients as compared with age and sex-matched controls, and the urinary excretion of 10 metabolites after oral load of the amino acid. This excretion increases in the cataract group both as total per cent and as kynurenine. No difference has been found in the free and total serum tryptophan between normal subjects and cataract patients. A possible role of the kynurenines in the pathogenesis of senile cataract is suggested.

    Full Text Available PURPOSE: Dynamic visual acuity (DVA is a relatively independent parameter for evaluating the ability to distinguish details of a moving target. The present study has been designed to discuss the extent to which age-related cataract impacts DVA in elderly individuals and to determine whether it could be restored after bilateral phacoemulsification combined with intraocular lens implantation surgery. METHODS: Twenty-six elderly cataract patients scheduled for binocular cataract surgery and 30 elderly volunteers without cataract were enrolled in the study. DVA at 15, 30, 60 and 90 degree per second (dps was assessed, and velocity-dependent visual acuity decreases between consecutive speed levels were calculated. RESULTS: Compared with the control group, the patient group exhibited significantly worse DVA performance at all speed levels (p<0.001, and the decreases in velocity-dependent visual acuity were more serious in the patient group at the intervals of 0-15 dps (p<0.001, 15-30 dps (p = 0.007 and 30-60 dps (p = 0.008. Postoperatively, DVA performance at every speed level in the patient group clearly improved (p<0.001 and recovered to levels compatible to the control group. The decrease in visual acuity with increasing speed was less pronounced than during the preoperative phase (p0-15 dps = 0.001, p15-30 dps<0.001 and p30-60 dps = 0.001 and became similar to that of the control group. The postoperative visual benefit regarding DVA was more pronounced than the improvement in static visual acuity (p15 dps = 0.001 and p<0.001 at 30 dps, 60 dps and 90 dps. CONCLUSIONS: The impact of age-related cataract on DVA was more severe than its effects on static visual acuity. After cataract surgery, not only static vision of the patients was restored markedly, but also the dynamic vision. DVA could be an important adjunct to the current evaluation system of functional vision, thereby meriting additional attention in clinical assessment.

    PurposeThe purpose of this study was to determine the long-term complications and outcomes of secondary intraocular lens (IOL) implantation in patients with congenital cataracts.Patients and MethodsThe medical records of children operated for secondary IOL implantation surgery between 2000 and 2014 were retrospectively reviewed. Those who had undergone their initial congenital cataract surgery before 7 months of age were included and were analyzed for intra- and postoperative factors and postoperative refractive outcomes. We focused on three complications: visual axis opacification (VAO), glaucoma, and IOL exchange after at least 1 year of follow-up.ResultsA total of 49 eyes of 49 patients were analyzed for intraoperative indications. Of those, 37 eyes of 37 patients had at least 1 year of follow-up and were analyzed for postoperative outcomes. The mean age at secondary implantation was 55.2±21.6 months. At secondary implantation, 69.4% of eyes were implanted in the capsular bag, 28.6% in the sulcus, and 2.0% that were angle-supported. There was no significant correlation between the site of secondary IOL implantation and age at implantation (P=0.216). The mean follow-up after implantation was 57.6±33.6 months. The rate of VAO was 5.4%, the rate of glaucoma occurring after secondary implantation was 16.2%, and the rate of IOL exchange was 2.7%. The median visual acuity at final follow-up was 20/40. For patients with unilateral cataracts it was 20/60 and for bilateral patients it was 20/30.ConclusionsThe secondary IOL implantation in children is a relatively safe procedure associated with low rates of postoperative complications. Visual outcomes are acceptable and are better for bilateral patients than for unilateral patients.

    Full Text Available A randomized single blinded clinical trial to compare the cost-effectiveness of cataract surgery between extracapsular cataract extraction (ECCE and phacoemulsification (PEA was conducted at Hospital Universiti Kebangsaan Malaysia (HUKM from March 2000 until August 2001. The cost of a cataract surgery incurred by hospital, patients and households were calculated preoperatively, one week, two months (for both techniques and six months (for ECCE only. Effectiveness of cataract surgery was assessed using Visual Function 14 (VF-14, quality of life measurement specifically for vision. The cost analysis results from each 50 subjects of ECCE and PEA group showed that average cost for one ECCE after six months post-operation is USD 458 (± USD 72 and for PEA is USD 528 (± USD 125. VF-14 score showed a significant increased after a week, two months and six months post-operation compared to the score before operation for both techniques (p<0.001. However, there was no significant difference between them (p = 0.225. This study indicated that ECCE is more cost effective compared to PEA with cost per one unit increment of VF-14 score of USD 14 compared to USD 20 for PEA.

    Purpose. The purpose of this study was to investigate the thiol repair systems of thioltransferase (TTase) and thioredoxin (Trx) and oxidation-damaged proteins in human cataractous lenses. Methods. Cataractous lenses in humans (57–85 years of age) were classified into cortical, nuclear, mixed, mature, and hypermature cataract types by using a lens opacity classification system, and were obtained by extracapsular cataract extraction (ECCE) procedure. Cortical and nuclear cataracts were grouped by decreasing order of visual acuity into optical chart reading (R), counting fingers (CF), hand motion (HM), and light perception (LP). ECCE lens homogenate was analyzed for glutathione (GSH) level and enzyme activities of TTase, glutathione reductase (GR), Trx, and thioredoxin reductase (TR). Cortical and nuclear cataractous lenses (8 of each) with visual acuity better than HM were each dissected into cortical and nuclear portions for measurement of glyceraldehyde 3-phosphate dehydrogenase (G3PD) activity. Clear lenses (in humans 49–71 years of age) were used as control. Results. Compared with control, all cataractous lenses lost more than 80% GSH and 70% GR; TR and Trx activity; and 40% to 70% TTase activity, corroborated with the loss in visual acuity. Among cataracts with R and CF visual acuity, cortical cataract lost more cortical G3PD activity (18% of control) than that of nuclear cataract (50% of control), whereas GSH depletion and TTase inactivation were similar in both cataracts. Conclusions. Thiol repair systems were damaged in all types of cataracts. Cortical and nuclear cataracts showed differential G3PD inactivation in the cortex, implying those 2 type of cataracts might be formed through different mechanisms. PMID:25537203

The KAMRA™ small aperture inlay was the first such inlay to receive Conformité Européenne (CE marking in 2005. It has been shown to improve uncorrected near and intermediate visual acuity without adversely affecting uncorrected distance visual acuity. Due to the age of presbyopic patients, they may eventually develop cataracts. In two such cases, we found that cataract surgery with the KAMRA implant left in place was not technically more difficult, and that the surgical procedure could be improved by additional ocular rotations to improve visualization. Biometry readings were reliable, and it appeared that the SRK/T formula was accurate for calculation of intraocular lens power. Cataract surgery with the KAMRA implant left in situ is a viable option for patients. Keywords: cataract surgery, KAMRA, corneal inlay, AcuTarget, presbyopia

    McMullen, R J; Utter, M E

    2010-03-01

    The purpose of this review is to discuss the evolution of equine cataract surgery over the past 50 years to its current stage. Equine cataract surgery is performed similarly compared with the techniques used in human ophthalmology and in other veterinary species. However, enough differences exist to make surgical lens removal and intraocular lens implantation in the horse an intrinsically unique endeavour. Due to the size of the adult equine globe, the introduction of species-specific instrumentation has provided the cornerstone to many of the changes made regarding surgical technique over the last 15-20 years. The continuing development of an equine specific, foldable intraocular lens implant (IOL) has provided much needed data supporting the use of such lenses in the horse to improve upon the post operative visual outcome. Finally, the methods utilised to assess visual capacity and the effects of intraocular lens implantation on the globe (e.g. ocular ultrasonography, electroretinography and streak retinoscopy) are gradually becoming more important in preoperative patient assessment and IOL development in the horse. It is the hope of the authors that a broader group of equine veterinarians will become aware of the many changes that have taken place in equine cataract surgery over the last half-century. Although aspiration was implemented nearly 40 years ago in foals for the treatment of congenital cataracts, phacofragmentation (phacoemulsification) techniques have only recently become routine in mature horses undergoing lens extraction.

    Full Text Available X-linked juvenile retinoschisis is a rare hereditary retinal disease characterized by a tangential splitting of the neurosensory retina which may cause early-onset visual impairment. Existence of the retinal neurosensory layer splitting on cross-sectional images of optical coherance tomography (OCT and the absence of leakage on fluorescein angiography (FA help confirming the diagnosis. Such diagnostic tests are also helpful in determining the management of the disease. However, most of the retinoschisis cavities remain stable and rarely extend to the posterior pole, many authors suggest laser prophylaxis to avoid the potential risk of retinal detachment due to holes in the outer retinal layer. Herein, we report a case with bilateral foveal retinoschisis accompanying unilateral peripheral retinoschisis who was evaluated with detailed ophthalmologic examination. Visual acuity, fundoscopy, OCT, and FA remained stable in the second year of follow-up after prophylactic argon laser treatment.

Methods: This retrospective comparative study was conducted on patients who had undergone a triple procedure. The technique of cataract extraction was either opensky extracapsular cataract extraction (ECCE or phacoemulsification (PE. In the ECCE group, the posterior chamber intraocular lens (PCIOL was implanted in the ciliary sulcus, while in the PE group PCIOLs were fixated within the capsular bag. Outcome measures included best spectacle corrected visual acuity (BSCVA, refractive results, graft clarity and complications. Results: Seventy-six eyes of 69 consecutive patients with mean age of 61.4±14.2 years were enrolled. Mean follow-up period was 61.4±37.2 months over which mean BSCVA was significantly improved from 1.40±0.68 to 0.44±0.33 LogMAR (P<0.001. Mean postoperative spherical equivalent refractive error was -2.13±3.02 D, which significantly differed from the target refraction (-0.73±0.29 D, P=0.004. At final follow-up, 89.5% of the corneal grafts remained clear. Conclusion: The triple procedure is a safe and effective approach to restore vision in patients with coexisting corneal pathologies and cataracts. However, unacceptable postoperative refractive error can be anticipated.

    Full Text Available Abstract Background If decisions on health care spending are to be as rational and objective as possible, knowledge on cost-effectiveness of routine care is essential. Our aim, therefore, was to evaluate the cost-utility of routine cataract surgery in a real-world setting. Methods Prospective assessment of health-related quality of life (HRQoL of patients undergoing cataract surgery. 219 patients (mean (SD age 71 (11 years entering cataract surgery (in 87 only first eye operated, in 73 both eyes operated, in 59 first eye had been operated earlier filled in the 15D HRQoL questionnaire before and six months after operation. Direct hospital costs were obtained from a clinical patient administration database and cost-utility analysis performed from the perspective of the secondary care provider extrapolating benefits of surgery to the remaining statistical life-expectancy of the patients. Results Mean (SD utility score (on a 0–1 scale increased statistically insignificantly from 0.82 (0.13 to 0.83 (0.14. Of the 15 dimensions of the HRQoL instrument, only seeing improved significantly after operation. Mean utility score improved statistically significantly only in patients reporting significant or major preoperative seeing problems. Of the subgroups, only those whose both eyes were operated during follow-up showed a statistically significant (p Conclusion Mean utility gain after routine cataract surgery in a real-world setting was relatively small and confined mostly to patients whose both eyes were operated. The cost of cataract surgery per quality-adjusted life year gained was much higher than previously reported and associated with considerable uncertainty.

METHODS: We conducted a population-based cross-sectional survey (from randomly selected block groups of Chinese Bai Nationality aged ≥50 years in southwestern China. Presenting visual acuity (PVA, best corrected visual acuity (BCVA were recorded and a detailed eye examination was carried out. For all aphakic and pseudophakic subjects identified, information on the date, setting, type, and complications of cataract surgery were recorded. In eyes with VA <20/63, the principal cause of visual impairment was identified. RESULTS: Of 2133 (77.8% of 2742 subjects, 99 people (129 eyes had undergone cataract surgery. The prevalence of cataract surgery was 4.6%. Surgical coverage among those with PVA <20/200 in both eyes because of cataract was 52.8%. Unoperated cataract was associated with older age. The main barrier to cataract surgery was lack of awareness and knowledge, cost, and fear. Among the 129 cataract-operated eyes, 22.5% had PVA of ≥20/32, 25.6% had PVA of 20/40 to 20/63, 23.3% had PVA <20/63 to 20/200, and 28.7% had PVA<20/200. With BCVA, the percentages were 42.6%, 23.3%, 10.9%, and 23.3%, respectively. Aphakia (odds ratio [OR], 8.49; P<0.001 and no education (OR, 10.18; P = 0.001 or less education (OR, 6.49; P = 0.014 were significantly associated with postoperative visual impairment defined by PVA, while aphakia (OR, 8.49; P<0.001 and female gender (OR, 4.19; P = 0.004 were significantly associated with postoperative visual impairment by BCVA. The main causes of postoperative visual impairment were refractive error, retinal disorders and glaucoma. CONCLUSIONS: Half of those with bilateral visual impairment or blindness because of cataract remain in need of cataract surgery in Bai population. Surgical uptake and visual outcomes should be further improved in the future.

    Congenital absence of tibia is a rare anomaly. We report a case of bilateral tibial hemimelia born to phenotypically normal parents. The two amputated legs with tibial dysplasia obtained from a 3-year-old boy were studied by radiography and anatomical dissection. The radiological evaluation revealed a normal hip joint. The lower end of femur was normal without any bifurcation, shortening or bowing. Fibula was present on both legs and there was no sign of bowing or doubling. Both right and left tibiae were absent. In addition, on the right side, five tarsal bones, two metatarsals and the corresponding digital rays were absent. On the left side, three tarsal bones were absent. Dissection of the amputated segments showed the presence of extensor digitorum longus, peroneus tertius, peroneus longus and brevis, gastrocnemius, and soleus. Following bilateral knee disarticulation the patient was fitted with prosthesis and is doing well.

    The author reports the case of a well and fit patient who presented herself to the emergency department and was found to have bilateral emphysematous pyelonephritis. She was admitted to the intensive care where she was initially treated conservatively with antibiotics, percutaneous drainage and continuous renal replacement therapy, but her condition deteriorated. She underwent a left total nephrectomy and a partial right nephrectomy that resulted in remarkable improvement. The patient started passing urine spontaneously, so no haemofiltration was required. She was discharged home and her case was followed-up by an urologist and nephrologist. This case lays emphasis on thoroughly investigating and managing a patient with bilateral emphysematous pyelonephritis and, in relation to its management, on the dilemma of whether the treatment of choice should be conservative or surgical.

    Juvenile mammary papillomatosis is a benign proliferative disease of young patients, generally under 30 years of age. The most frequent clinical presentation is the existence of an elastic and mobile lymph node of the breast. Anatomopathologically, it is characterized because it presents ductal epithelial hyperplasia, sometimes with marked atypia, and there are numerous cysts having different sizes among the findings. It has been associated with an increase in the incidence of breast cancer, both in the patient herself as well as her family. We review the literature on the subject and present the mammographic and ultrasonographic findings of a 22 year old woman diagnosed of juvenile mammary papillomatosis. (Author) 12 refs.

    Full Text Available As we near the end of this century, refractive cataract surgery has become a reality through concerted contributions from ultrasonic phacoemulsification, foldable intraocular lens (IOL implantation technology and keratorefractive surgery. As we enter the new millennium, our sights are set on realizing another dream: accommodative IOL surgery. Towards achieving this goal, many advances have been made in both techniques and technology of cataract removal. Lasers in particular have been under investigation for cataract removal for nearly two decades. The technology has now reached a stage where cataract can indeed be removed entirely with laser alone. Neodymium:YAG and erbium:YAG are the laser sources currently utilized by manufacturers of laser phaco systems. Initial clinical experience reported in the literature has served to highlight the capabilities of lasers and the need for further refinement. Despite the excitement associated with the availability of this alluring new technology for cataract removal, it is necessary to develop more effective laser systems and innovative surgical techniques that optimize its capabilities if laser phaco surgery is to be a genuine improvement over current techniques.

The demographic details of patients, type of surgery done, as well as type of anaesthesia used and experience of the surgeon were noted. The types of intraoperative and postoperative complications were recorded. The final best corrected visual outcome was recorded.RESULTS: Complications occurred in 11.1% of the total 1007 patients operated. Posterior capsule rupture(3.6%was the most common complication. The experience of the surgeon and the type of anaesthesia used did not affect complications during surgery. Intracapsular cataract extraction(ICCEand phacoemulsification converted to extracapsular cataract extraction(ECCEwere significantly associated with more complications(PPCONCLUSION: The occurrence of complications during cataract surgery significantly affected the visual outcome. The type of surgery done was associated by the occurrence of complications. However, the experience of the surgeon and the type of anaesthesia used did not affect the occurrence of complications. We recommend that particular attention be given to ICCE and phacoemulsification converted to ECCE to minimise the complications and thereby reducing the chances of poor vision postoperatively.

    2014-01-01

    Full Text Available Aims: To report the technique and outcomes of sutureless manual cataract extraction via a subconjunctival limbus oblique incision for mature cataracts. Materials and Methods: This retrospective study comprised of 112 eyes of 83 patients with mature cataract who all had manual cataract extraction via a subconjunctival limbus oblique incision. A transconjunctival tunnel is fashioned with a 3.0 mm keratome, 0.5 mm behind the limbal vascular arcades. A limbal tunnel, with a transverse extent of 9 mm in the cornea and 7.0 mm in the limbus, is created beneath the conjunctival/Tenon′s tissue using an angled bevel-up crescent blade. Outcome measures included visual acuity, intraoperative complications, surgically induced astigmatism, endothelial cell loss rate and surgery time. Results: Self-sealing wound was achieved in 112 eyes (98.2%. The nucleus was delivered in whole in 108 eyes (96.4%. Intraoperative complications included hyphema in 3 eyes (2.7%, iridodialysis in 2 eyes 1.8%, posterior capsular rupture and zonular dialysis in 2 eyes (1.8%. At the 3-month follow-up, 91% patients achieved a best-corrected visual acuity of 20/20 or better, the mean of surgically induced astigmatism was -0.62 ± 0.41 Diopters and endothelial cell loss was 4.2%. Average surgical time was 3.75 min per case. Conclusion: This subconjunctival limbus oblique incision has the potential to serve as safe and effective technique for mature cataracts.

    Gayadine-Harricham, Y; Amzallag, T

    2017-06-01

    In our practice, patients undergoing bilateral cataract surgery complain of more significant pain after the 2nd eye surgery. The goal of this study was to compare postoperative pain between the 1st and 2nd eyes with cataract surgery under topical anesthesia and to identify the causes of this pain. We conducted a prospective observational study between May and September 2015. We included 69 consecutive adults scheduled for bilateral cataract surgery under topical anesthesia within 2 months by the same surgeon. A self-assessment questionnaire of anxiety (the Amsterdam Preoperative Anxiety and Information Scale [APAIS]) was completed before each procedure. Postoperative pain was assessed by the visual analogue scale (VAS) in the recovery room. Among the 69 included patients (mean age: 70±1.3 years), 13 (19%) experienced more pain after the 2nd eye procedure. The median VAS was 0 (EI: 0-1) after the first eye versus 0 (EI: 0-2) after the second eye (P=0.836). The patients with the most pain after the second eye surgery had a median anxiety score of 5 (EI: 4 to 9.5), which was comparable to those without pain (P=0.589). On bivariate analysis, women had more pain after second eye surgery (27%) than men (4%) (P=0.026). However, this association lost its significance when the analysis was adjusted for the level of anxiety (adjusted OR 7.7, 95% CI [0.91; 64.6]). In fact, women were more anxious [median anxiety score of 6 (EI: 4 to 8.5)] before 2nd eye surgery than men [median score: 4 (EI: 4-6); P=0.013]. Pain levels appeared to be very moderate on both sides when measured postoperatively, as opposed to statements often made in the immediate postoperative period. There is a discrepancy with the literature data. However, each study had small sample sizes. We did not find any significant difference in pain between 1st and 2nd eye cataract surgery under topical local anesthesia. While postoperative pain appeared greater among women, we have noted the possible influence of

    Cataract and insufficient vitamin D intake are both increasing worldwide concerns, yet little is known about the relationship between serum 25-hydroxyvitamin D (25(OH)D) levels and age-related cataract. We performed this study to determine the association between serum 25(OH)D levels and age-related cataract in adults. Study participants comprised 16,086 adults aged 40 years or older who had never been diagnosed with or undergone surgery for cataract using Korean National Health and Nutrition Examination Survey data from 2008 to 2012. Participants were assessed to have cataract when diagnosed with cortical, nuclear, anterior subcapsular, posterior subcapsular, or mixed cataract. Odds ratios (ORs) and 95% confidence intervals (CIs) were used to evaluate the magnitude and significance of the association between serum 25(OH)D levels and cataract in multivariable logistic regression models. The OR for nuclear cataract with the highest quintile of serum 25(OH)D levels was 0.86 (95% CI 0.75-0.99) compared to the lowest quintile. A linear trend across quintiles was significant. Natural log-transformed serum 25(OH)D levels were also significantly associated with nuclear cataract (OR 0.84, 95% CI 0.75-0.95). The opulation-attributable fraction of nuclear cataract due to serum 25(OH)D insufficiency (D levels were inversely associated with the risk of nuclear cataract. Prospective studies investigating the effects of serum 25(OH)D levels on the development of nuclear cataract are needed to confirm our findings.

    Full Text Available Cataract surgery is one of the most successful and frequently performed operations worldwide, and yet cataract remains the commonest cause of global blindness. This is in part due to the shortage and uneven distribution of trained personnel in some countries. More worryingly, a high rate of cataract blindness also reflects poor visual outcomes after surgery, as has been documented in many RAAB (rapid assessment of avoidable blindness studies.

  3. Elevated frequency of cataracts in birds from chernobyl.

    Directory of Open Access Journals (Sweden)

    Timothy Alexander Mousseau

    Full Text Available BACKGROUND: Radiation cataracts develop as a consequence of the effects of ionizing radiation on the development of the lens of the eye with an opaque lens reducing or eliminating the ability to see. Therefore, we would expect cataracts to be associated with reduced fitness in free-living animals. METHODOLOGY/PRINCIPAL FINDINGS: We investigated the incidence of lens opacities typical of cataracts in more than 1100 free-living birds in the Chernobyl region in relation to background radiation. The incidence of cataracts increased with level of background radiation both in analyses based on a dichotomous score and in analyses of continuous scores of intensity of cataracts. The odds ratio per unit change in the regressor was 0.722 (95% CI 0.648, 0.804, which was less than odds ratios from investigations of radiation cataracts in humans. The relatively small odds ratio may be due to increased mortality in birds with cataracts. We found a stronger negative relationship between bird abundance and background radiation when the frequency of cataracts was higher, but also a direct effect of radiation on abundance, suggesting that radiation indirectly affects abundance negatively through an increase in the frequency of cataracts in bird populations, but also through direct effects of radiation on other diseases, food abundance and interactions with other species. There was no increase in incidence of cataracts with increasing age, suggesting that yearlings and older individuals were similarly affected as is typical of radiation cataract. CONCLUSIONS/SIGNIFICANCE: These findings suggest that cataracts are an under-estimated cause of morbidity in free-living birds and, by inference, other vertebrates in areas contaminated with radioactive materials.

    To report a series of cases involving neovascularization within the human crystalline lens-a normally avascular structure-after ocular trauma. This is a retrospective, consecutive observational case series with review of the prevailing literature. Four individuals with a history of ocular trauma and subsequent cataract development were examined between May 2004 and April 2007. All had hypermature cataracts and intraocular inflammation, presumably secondary to phacolysis; two of the four had concurrent hyphema and ocular hypertension in the involved eye. All subjects in this series were found to display a discrete network of blood vessels within the structure of the crystalline lens, just beneath the anterior lens capsule. Neovascularization of the crystalline lens has received little attention in the ophthalmic literature, having been described only rarely in individual case reports. This manuscript details the first known case series involving lenticular neovascularization, and offers insight into its possible developmental mechanism.

  6. Management of the hard posterior polar cataract.

    Chee, Soon-Phaik

    2007-09-01

    I describe a technique for managing the posterior polar cataract with a dense nucleus by initially sculpting a central trough to the depth of the polar opacity. The nucleus is partially cracked in the periphery, avoiding the polar opacity, and then chopped into quadrants without rotating. Next, the phaco tip engages the core of the nuclear quadrant while a cleavage plane is manually dissected along the lenticular lamellae using a Nagahara phaco chopper, with the tip rotated slightly so it points somewhat toward the equator of the lens, to a depth estimated to leave a nuclear shell, sparing the polar cataract. The nucleus is peeled away from the outer nucleus shell, which is kept in place by the phaco chopper. The intact nuclear plate is removed last and any capsular defect managed accordingly. This technique minimizes the risk for losing a nuclear fragment into the vitreous cavity.

    The purpose of this study was to describe and analyze the prevalence and pattern of corneal astigmatism in cataract surgery candidates. In a prospective cross-sectional study, preoperative demographics, and keratometric and refractive values of cataract surgery candidates were collected from January 2013 to December 2014. Axial length (AL) and flat and steep keratometry measurements were optically measured by a partial coherence interferometry device (IOLMaster). This study consisted of 2156 eyes of 1317 patients with a mean age of 64.92 ± 11.48 (SD) (30-88 years). The mean of AL was 23.33 ± 1.37 mm, and the mean of corneal astigmatism was 1.12 ± 1.10 diopter (D) (range 0.0-7.00), in all patients. Furthermore, the mean of flat and steep keratometry were 43.70 ± 1.70 and 44.83 ± 1.79 D, respectively. Corneal astigmatism was 1.50 D or less in 1590 eyes (73.7 %), more than 1.50 D in 566 eyes (26.2 %), 3.00 D or more in 161 eyes (7.4 %), WTR in 796 eyes (36.9 %), ATR in 1010 eyes (46.8 %), and oblique in 350 eyes (16.2 %). ATR astigmatism axis significantly increased with the increase in age. Corneal astigmatism of most cataract surgery candidates fell between 0.50 and 1.50 D. The results of our study however is confined to our demographics might provide useful data for cataract patients, surgeons, and intraocular lens manufacturers for different purposes.

    Full Text Available Abstract Background Consensus techniques have been used previously to create explicit criteria to prioritize cataract extraction; however, the appropriateness of the intervention was not included explicitly in previous studies. We developed a prioritization tool for cataract extraction according to the RAND method. Methods Criteria were developed using a modified Delphi panel judgment process. A panel of 11 ophthalmologists was assembled. Ratings were analyzed regarding the level of agreement among panelists. We studied the effect of all variables on the final panel score using general linear and logistic regression models. Priority scoring systems were developed by means of optimal scaling and general linear models. The explicit criteria developed were summarized by means of regression tree analysis. Results Eight variables were considered to create the indications. Of the 310 indications that the panel evaluated, 22.6% were considered high priority, 52.3% intermediate priority, and 25.2% low priority. Agreement was reached for 31.9% of the indications and disagreement for 0.3%. Logistic regression and general linear models showed that the preoperative visual acuity of the cataractous eye, visual function, and anticipated visual acuity postoperatively were the most influential variables. Alternative and simple scoring systems were obtained by optimal scaling and general linear models where the previous variables were also the most important. The decision tree also shows the importance of the previous variables and the appropriateness of the intervention. Conclusion Our results showed acceptable validity as an evaluation and management tool for prioritizing cataract extraction. It also provides easy algorithms for use in clinical practice.

First-year, second-year, and third-year residents performed a mean of 2, 25, and 155 phacoemulsification surgeries, respectively, as a primary surgeon. Only 1 program (2%) required residents to perform extracapsular cataract extraction (ECCE) before performing phacoemulsification. Clear corneal phacoemulsification was the first technique taught to trainees at 91% of programs. More than two thirds (71%) of program directors indicated that their program had a cataract surgery training curriculum designed to transition residents gradually to the operating room. These curricula included structured wet laboratory (92%) and lecture (89%) components. Inadequate resident knowledge and surgical skill base (57%) and anticipation of increased surgical complication risk (37%) were the most commonly reported factors impeding earlier exposure to phacoemulsification in residency. Results show that residents today begin surgical training with phacoemulsification rather than ECCE, perform a higher number of phacoemulsification surgeries than is required by the ACGME, and begin performing phacoemulsification as early as their first or second year of residency. Despite these evolutions, 29% of respondent ACGME-accredited ophthalmology residency programs reported not having a formal cataract surgery training curriculum. Copyright © 2016 ASCRS and ESCRS.

    Full Text Available Seasonal adaptation is a ubiquitous behavior seen in many species on both global hemispheres and is conveyed by changing photoperiods. In humans this seasonal adaptation is less apparent, in part because changes in daylength are masked by the use of electrical lighting at night. On the other hand, cataracts which reduce light transmission, may compound seasonal changes related to the reduced daylength of winter. To better understand the effects of different photoperiod lengths in healthy adults without and with cataracts, we tested their melanopsin-mediated light responses in summer vs. winter. Fifty-two participants (mean age 67.4 years; 30 with bilateral cataracts and 22 age-matched controls with clear lenses; pseudophakes were tested twice, once in summer and once in winter. At each test session we assessed the electroretinogram and pupil responses during daytime and we determined melatonin suppression, subjective sleepiness and mood in response to light exposure in the evening. Circadian rest-activity cycles and sleep from activity recordings were also analyzed for both seasons. Both groups had similar visual function. There were no seasonal differences in the electroretinogram. For the pupil responses to bright blue light, the post-illumination pupil response (PIPR was greater in winter than summer in pseudophakes, but not in cataract participants, whereas melatonin suppression to acute light exposure showed no differences between both groups and seasons. Overall, intra-daily variability of rest-activity was worse in winter but participants felt sleepier and reported worse mood at the laboratory in evening time in the summer. Those with cataracts had poorer sleep quality with lower sleep efficiency, and higher activity during sleep in winter than summer. In this study, the PIPR showed a seasonal variation in which a larger response was found during winter. This variation was only detected in participants with a clear intraocular lens. In

    Full Text Available : INTRODUCTION: Ocular trauma is the leading cause of unilateral blindness all over the world.[1] The incidence of ocular trauma varies in different parts of the world. From India, the reported incidence is 20.53%.[2] Any strategy for prevention requires knowledge of the cause of injury, which may enable more appropriate targeting of resources towards preventing such injuries.[3] Eye trauma represents a large, potentially preventable burden on both victims and society as a whole. Traumatic cataracts occur secondary to blunt or penetrating ocular trauma, Infrared energy (glass-blower's cataract, electric shock and ionizing radiation are other rare causes of traumatic cataracts.[4] It form a separate category of cataracts as they present with other ocular morbidity like corneal tears, iris injury, vitreous hemorrhage and retinal tears; and they are to some extent, preventable. The methods used to evaluate the visual outcome in eyes managed for traumatic cataracts and senile cataracts are similar, but the damage to other ocular tissues owing to trauma may compromise the visual gain in eyes treated surgically for traumatic cataracts.[5] Hence, the success rates may differ between eyes with these two types of cataract. The aim of this study was to evaluate the final visual outcome of a patient with surgical extraction of traumatic cataract along with demographic features and modes of trauma.

    to evaluate the efficiency of new torsional phacoemulsification software (Ozil IP system) in hard nucleus cataract extraction. 45 eyes with hard senile cataract (degree III and IV) underwent phacoemulsification performed by the same surgeon, using the same technique (stop and chop). Infiniti (Alcon) platform was used, with Ozil IP software and Kelman phaco tip miniflared, 45 degrees. The nucleus was split into two and after that the first half was phacoemulsificated with IP-on (group 1) and the second half with IP-off (group 2). For every group we measured: cumulative dissipated energy (CDE), numbers of tip closure that needed manual desobstruction the amount of BSS used. The mean CDE was the same in group 1 and in group 2 (between 6.2 and 14.9). The incidence of occlusion that needed manual desobstruction was lower in group 1 (5 times) than in group 2 (13 times). Group 2 used more BSS compared to group 1. The new torsional software (IP system) significantly decreased occlusion time and balanced salt solution use over standard torsional software, particularly with denser cataracts.

    Full Text Available Methylphenidate hydrochloride (Ritalin is the drug of choice for attention deficit hyperactivity disorder (ADHD. However, an association of Ritalin with glaucoma has been reported. We report a case of Ritalin-associated cataract and glaucoma. A 10-year-old boy was diagnosed with ADHD and had received methylphenidate hydrochloride, 60 mg/day for 2 years. He presented with blurred vision. Best-corrected visual acuity was 6/60 in both eyes. Ocular examinations revealed intraocular pressure (IOP of 30 mmHg under medication, dense posterior subcapsular opacity of lens, pale disc with advanced cupping, and marked constriction of visual field. Despite maximal anti-glaucomatous medication, IOP still could not be controlled. The patient then received combined cataract and glaucoma surgery. Visual acuity improved and IOP was within normal limits in both eyes postoperatively. Large dose of methylphenidate may cause cataract and glaucoma. The mechanism remains unclear. Doctors should be aware of the possible ocular side effects of methylphenidate.

    Full Text Available In infants& children variety of conditions and syndromes are associated with difficult Airway. Anaesthetic management becomes a challenge if it remains unrecognized until induction and sometimes results in disaster, leading to oropharyngeal trauma, laryngeal oedema, cardiovascular& neurological complications. A 4-month-old child with multiple congenital anomalies was posted for cataract extraction for early and better development of vision. He had history of post birth respiratory distress, difficulty in feeding, breath holding with delayed mile stones. He was treated as for Juvenile asthma. This child was induced with inhalation anaesthesia. There was difficulty in laryngoscopic intubation and could pass much smaller size of the tube than predicted. He developed post operative stridor and desaturation. The problems which we faced during the anaesthetic management and during postoperative period are discussed with this case.

    Bilateral optic neuropathy with bilateral putaminal lesions may be caused by methanol or cyanide poisoning or mitochondrial disorders including Leber hereditary optic neuropathy and Leigh syndrome. We report the case of a 34-year-old Japanese man who developed bilateral visual loss 5 days after the development of gastrointestinal symptoms. Magnetic resonance imaging of the brain on admission revealed high-intensity signal areas in the bilateral putamina on diffusion-weighted and T2-weighted images as well as a high-intensity signal area in the left middle cerebellar peduncle that had been identified 3 years previously. We diagnosed bilateral optic neuropathy with bilateral putaminal lesions caused by preceding infection-triggered demyelination. We administered methylprednisolone, but his vision did not recover.

    The subscapular artery arises from the third part of the axillary artery and gives off the circumflex scapular and the thoracodorsal arteries. Although anatomical variations of the axillary artery are very common, the existence of a unilateral accessory thoracodorsal artery has been described in the literature only once. There are no reports of bilateral accessory thoracodorsal artery, in the literature. In the present study, a bilateral accessory thoracodorsal artery, originating on either side of the third part of the axillary artery, is described in a 68-year-old female cadaver. All the other branches of the axillary artery had a typical origin, course, distribution and termination. This extremely rare anatomical variation apart from the anatomical importance also has clinical significance for surgeons in this area. Especially, during the dissection or mobilization of the latissimus dorsi that is partly used for coverage problems in many regions of the body and also in dynamic cardiomyoplasty, any iatrogenic injury of this accessory artery may result in ischemia and functional loss of the graft.

    Full Text Available BACKGROUND Control of childhood blindness is one of the priorities identified for achieving the goals of Vision-2020 by WHO. This is considered a priority because blind-years (number of years that a blind person lives after going blind due to childhood blindness are second only to cataract and half of childhood blindness is avoidable (treatable/preventable. Paediatric cataract accounts for 12% of the 1.4 million blind children globally. The prevalence of childhood cataract has been reported as 1 to 15 cases in 10,000 children in developing countries. Compared to industrialised countries, this figure is 10 times higher. Early detection and timely treatment of various childhood disorders such as congenital cataract are the most crucial factors for successful outcome. A suitable measure to address amblyopia and posterior capsule opacification post operatively is imperative for successful visual rehabilitation of such children. The objectives of this study were- 1 To study the clinical profile of paediatric cataract. 2 To evaluate the visual outcome after cataract surgery in these patients. 3 To evaluate different causes of visual impairment following management. MATERIALS AND METHODS A prospective study conducted at Karnataka institute of medical sciences department of ophthalmology from October 2015 to September 2016. All children below 14 years of age presenting with cataract will undergo thorough ophthalmologic examination and cataract surgery. RESULTS The results of the present study with 25 paediatric patients (36 eyes indicates that excellent vision can be expected after cataract surgery and posterior chamber IOL implantation coupled with appropriate amblyopia therapy. CONCLUSION The paediatric cataract patients are referred from primary health centers, and district hospital from north Karnataka to KIMS Hubli. All paediatric patients are from lower socio economic status. Early detection of cataracts and referrals to the ophthalmologist can

    Sexual offending by juveniles accounts for a sizable percentage of sexual offenses, especially against young children. In this article, recent research on female juvenile sex offenders (JSOs), risk factors for offending in juveniles, treatment, and the ways in which these youth may differ from general delinquents will be reviewed. Most JSOs do not go on to develop paraphilic disorders or to commit sex offenses during adulthood, and as a group, they are more similar to nonsexual offending juvenile delinquents than to adult sex offenders. Recent research has elucidated some differences between youth who commit sex offenses and general delinquents in the areas of atypical sexual interests, the use of pornography, and early sexual victimization during childhood.

    The endothelium should be carefully evaluated when choosing a surgical technique for cataract removal. Therefore, we aimed to study the effects of different cataract surgery techniques on endothelial cell loss in transplanted corneal grafts. A total of 54 patients who received complicated cataract surgery in post-penetrating keratoplasty (PKP) eyes at the Shandong Eye Institute between February 2001 and June 2014 were included, and clinical records were reviewed. Baseline demographic details, clinical characteristics, endothelial cell density (ECD), and best-corrected visual acuity (BCVA) were recorded. Wilcoxon rank-sum test and Wilcoxon signed-rank test were used to test the equality of medians. A regression model was constructed to compare the reduced rate of ECD. Of the 54 eyes included in this study, extracapsular cataract extraction (ECCE) was performed in 34 eyes of 33 patients (ECCE group) whereas phacoemulsification was performed in 20 eyes of 20 patients (phacoemulsification group). There was no significant difference in the median age (P = 0.081) or preoperative ECD (P = 0.585) between the two groups. At 6 months after cataract surgery, ECD in ECCE group was significantly higher than that in phacoemulsification group (P = 0.043). In addition, the endothelial cell loss rate in ECCE group was significantly lower than that in phacoemulsification group at 2 months (P = 0.018), 4 months (P ECCE group (P ECCE in transplanted corneal grafts (P ECCE is more suitable than phacoemulsification in cataract surgery in complicated cataract after PKP.

    the small-incision cataract surgery is gaining popularity among the ophthalmic surgeons. to compare the visual outcome of conventional extra-capsular cataract extraction (ECCE) and small-incision cataract surgery (SICS) in a hospital based community cataract program. aprospective interventional study without randomization was carried out including the patients undergoing cataract surgery by either conventional ECCE or manual SICS. They were followed up for 6 weeks postoperatively. The visual outcomes were compared between the two groups. the statistical program Epi-Info version 2000 was used to analyze the data. Mean values with standard deviations, 95% CI and p value were calculated. The p value ofECCE and 41 (M: F=15:26) SICS (RR= 0.71, 95% CI=0.42-1.2, p value=0.16). Unaided visual acuity on the 1st postoperative day in the ECCE group was e"6/ 18 in 22.7%,ECCE group was e"6/18 in 79.5%,ECCE and SICS are good procedures for hospital based community cataract surgery but within the 6 weeks postoperative period SICS gives better visual outcome. Remarkably higher number of female patients can be provided service in a hospital based community cataract programme as compared to males.

    Abstract Purpose: To evaluate the clinical results of toric trifocal diffractive intraocular lens in eyes with cataract and mild keratoconus. Methods: Five keratoconus patients (10 eyes) that had bilateral AT LISA 939 implantation were selected and had followed in 3-time horizons of 1, 3, and 6 months. Patients were 46 to 65 years old age, corneal astigmatism of (2.00 D at 6.75 D) and cataract that all of them needed cataract surgery. The distance, intermediate and near visual acuities, defocus curve, ocular aberrations, contrast sensitivity, were measured as effectiveness criteria. Results: Average of binocular uncorrected distance visual acuity (UDVA) improved from 0.72 log MAR ± 0.11 (SD) to 0.04 ± 0.04 (P < 0.05) log MAR, average of uncorrected binocular intermediate visual acuity (UIVA) (80 cm) improved from 0.52 ± 0.07 log MAR to 0.14 ± 0.04 (P < 0.05) log MAR, and average of binocular uncorrected near visual acuity (UNVA) improved from 0.48 ± 0.09 log MAR to 0.02 ± 0.07 (P < 0.05) log MAR at 6 months, respectively. Contrast sensitivity testing showed acceptable results, the binocular defocus curve corroborate were in appropriate good visual acuity even at the intermediate distances, by a gentle slope less than log MAR 0.2 at −1.5 D, with regard to the best distance visual acuity at the 0 D defocus. Conclusions: Trifocal AT LISA 939MP IOLs provided appropriate distances, near and intermediate of the visual results. Prediction of the refractive results and optical performances were good.

    Introduction Fuchs Heterochromic Iridocylitis (FHI) is a rare form of uveitis which is frequently complicated by cataract and glaucoma, but it does not show typical features of uveitis like pain, redness and posterior synechia. Aim To study the clinical characteristics and outcome of cataract extraction with Intra Ocular Lens (IOL) implantation in patients with FHI. Materials and Methods The present prospective study was carried out in the Postgraduate Department of Ophthalmology, Sher-i-Kashmir Institute of Medical Sciences (SKIMS), Bemina from March 2012 to January 2015. The study included 33 eyes of 32 patients of FHI who underwent thorough clinical examination and cataract surgery with IOL implantation and were evaluated based on their visual outcome and intra and post-operative complications. Post-operative follow-up was done on 1st day, one week, one month, two month, six month and at twelve months. Results Mean age of our study group was 33.9 years (Range 18 to 65 years). No male or female preponderance was seen. There was bilateral involvement of eyes in only one case. Cataract and stellate keratic precipitates were present in all cases whereas, heterochromia was present in only six eyes (18.75%). Best Corrected Visual Acuity (BCVA) showed a significant improvement following cataract surgery (p 6/12). Most common causes of decreased vision post-operatively were vitreous opacities in nine eyes (27.27%) followed by glaucoma in eight eyes (24.24%) and posterior capsular opacification in six eyes (18.18%). Conclusion Cataract extraction with IOL lens implantation in FHI is a safe procedure associated with good visual prognosis and few complications. However, glaucoma is one of the main concerns and should be closely monitored both pre and post-operatively. PMID:28208900

  13. A COMPARATIVE STUDY OF THE AMOUNT OF ASTIGMATISM FOLLOWING CONVENTIONAL EXTRACAPSULAR CATARACT EXTRACTION AND MANUAL SMALL INCISION CATARACT SURGERY

    Full Text Available BACKGROUND Cataract is the principal cause of avoidable blindness in India and throughout the world. Surgical removal of the cataractous lens remains the only effective treatment for management of cataract blindness. The success of cataract surgery is determined by best and earliest visual recovery. But the occurrence of postoperative astigmatism has become a major hurdle in achieving this goal. AIMS The study was designed to compare the amount of astigmatism following conventional extracapsular cataract extraction (ECCE and manual small incision cataract surgery (SICS. MATERIALS AND METHODS The study was carried out in 100 eyes of 75 patients aged between 50 and 80 years admitted for cataract surgery. Out of these, 50 eyes were operated by conventional extracapsular cataract extraction and 50 eyes by manual small incision cataract surgery. The patients were followed up at 2 nd , 4 th , 6 th and 8 th weeks. At each follow-up visual acuity, refraction and acceptance and keratometry were recorded and the findings analysed for astigmatism. RESULTS In the current study, the mean (SD astigmatism developed at the end of the 2 nd , 4 th and 6 th of follow-up was significantly lower in the SICS group as compared to the ECCE group (P<0.000. At the end of 8 weeks of follow-up, the mean (SD astigmatism of the SICS group was 0.64±0.56 D as compared to the mean (SD of the ECCE group of 1.39±86 D and the difference was found to be significant (p<0.014. CONCLUSION The current study concludes that manual small incision cataract surgery is a better technique to control postoperative astigmatism than conventional extracapsular cataract extraction.

    Summary Background To evaluate the safety, etiology and outcomes of patients undergoing bilateral thoracentesis. Methods This is a prospective cohort study of 100 consecutive patients who underwent bilateral thoracenteses in an academic medical center from July 2009 through November 2010. Pleural fluid characteristics and etiologies of the effusions were assessed. Mean differences in levels of fluid characteristics between right and left lungs were tested. Associations between fluid characteristics and occurrence of bilateral malignant effusions were evaluated. The rate of pneumothorax and other complications subsequent to bilateral thoracentesis was determined. Results Exudates were more common than transudates, and most effusions had multiple etiologies, with 83% having two or more etiologies. Bilateral malignant effusions occurred in 19 patients, were the most common single etiology of exudative effusions, and were associated with higher levels of protein and LDH in the pleural fluid. Among 200 thoracenteses performed with a bilateral procedure, seven resulted in pneumothoraces, three of which required chest tube drainage and four were ex vacuo. Conclusions More often than not, there are multiple etiologies that contribute to pleural fluid formation, and of the combinations of etiologies observed congestive heart failure was the most frequent contributor. Exudative effusions are more common than transudates when bilateral effusions are present. Malignancy is a common etiology of exudative effusions. This study suggests that the overall complication rate following bilateral thoracentesis is low and the rate of pneumothorax subsequent to bilateral thoracentesis is comparable to unilateral thoracentesis.

    Full Text Available Cataract remains the leading cause of blindness in Africa. We performed a systematic literature search of articles reporting barriers to cataract surgery in Africa. PubMed and Google Scholar databases were searched with the terms "barriers, cataract, Africa, cataract surgery, cataract surgical coverage (CSC, and rapid assessment of avoidable blindness (RAAB." The review covered from 1999 to 2014. In RAAB studies, barriers related to awareness and access were more commonly reported than acceptance. Other type of studies reported cost as the most common barrier. Some qualitative studies tended to report community and family dynamics as barriers to cataract surgery. CSC was lower in females in 88.2% of the studies. The variability in outcomes of studies of barriers to cataract surgery could be due to context and the type of data collection. It is likely that qualitative data will provide a deeper understanding of the complex social, family, community, financial and gender issues relating to barriers to uptake of cataract surgery in Africa.

    Purpose To evaluate the long-term visual outcomes and complications of cataract surgery in eyes previously treated for retinoblastoma. Methods We reviewed the medical records of patients who underwent cataract extraction and intraocular lens implantation at Seoul National University Children's Hospital for a secondary cataract that developed after retinoblastoma treatment. Results During the period between 1990 and 2014, 208 eyes of 147 patients received eye-salvaging treatment (radiotherapy, chemotherapy, and local therapy) for retinoblastoma at Seoul National University Children's Hospital. Among these eyes, a secondary cataract was detected in 17 eyes of 14 patients, and five eyes of five patients underwent cataract surgery. The median age of cataract formation was 97 months (range, 38 to 153 months). The medial interval between the diagnosis of retinoblastoma and cataract formation was 79 months (range, 29 to 140 months). All patients received posterior chamber intraocular lens insertion after irrigation and aspiration of the lens through a scleral tunnel incision. Anterior vitrectomy and posterior capsulotomy were performed in two eyes and a laser capsulotomy was subsequently performed in one eye. No intraoperative and postoperative complications occurred. The median follow-up after surgery was 36 months (range, 14 to 47 months). The final best corrected visual acuities were improved in all five eyes. No intraocular tumor recurrences or metastases occurred. Conclusions After retinoblastoma regression, cataract extraction in our series was not associated with tumor recurrence or metastasis. Visual improvement was noted in every patient. PMID:28243024

    Full Text Available Pur po se: To evaluate the long-term visual outcome and to determine the surgical complications after cataract surgery in patients with unilateral childhood cataract. Ma te ri al and Met hod: We retrospectively reviewed the records of 18 cases with unilateral childhood cataract who had undergone cataract surgery before the age of seven. Primary intraocular lens (IOL implantation was made in children who were older than 1 year of age. Secondary IOL implantation was made after 18 months in children who were operated before the age of 1 year and were left aphakic. Occlusion therapy was performed to all children for amblyopia postoperatively. Visual acuity and complications were evaluated in a mean follow-up period of 4.8 years. Re sults: The mean age of the 18 patients (9 female/9 male at the time of surgery was 43.6±33.7(1-84 months. Eleven (61% patients had cataract surgery after 1 year of age. Secondary IOL implantation was performed at mean 28th month in 4 of 7 aphakic patients (57% who had cataract surgery before one year of age. In 3 (43% aphakic patients, secondary IOL implantation could not be performed because of ocular pathologies such as microophthalmia. Final visual acuity was 0.5 or better in 7 eyes (39%, between 0.1 and 0.5 in 6 eyes (33%, and worse than 0.1 - in 5 eyes (28%. Of 5 eyes that had visual acuity worse than 0.1, 4 (80% had at least one additional ocular pathology such as microphthalmia, strabismus and nystagmus. Nd:YAG laser posterior capsulotomy was performed at mean 8th month in 7 of 8 (87% children whose posterior capsules were left intact at surgery. Dis cus si on: Favorable visual outcomes can be achieved with surgical intervention and complementary amblyopia treatment in children with unilateral cataract. Preoperative microphthalmia, nystagmus and strabismus are not entirely an obstacle to visual development, but they are important factors leading to low visual acuity.

    Full Text Available Bloody tear is a rare and distinct clinic phenomenon. We report a case presenting with the complaint of recurrent episodes of bilateral bloody tearing. A 16-year-old girl presented to our clinic with complaint of bloody tearing in both eyes for 3 months. Bloody tearing was not associated with her menses. A blood-stained discharge from the punctum was not observed during the compression of both nasolacrimal ducts. Nasolacrimal passage was not obstructed. Imaging studies such as dacryocystography and gradient-echo magnetic resonance imaging (MRI of nasolacrimal canal were normal. Intranasal endoscopic evaluation was normal. We collected samples from bloody tears two times and pathological examination was performed. Pathological analysis showed lots of squamous cells and no endometrial cells; dysplastic cells were found. Further evaluations for underlying causes were unremarkable. No abnormalities were found in ophthalmologic, radiologic, and pathologic investigations. This condition is likely a rare abnormality and the least recognized aetiology for the idiopathic phenomenon.

    Cochlear implant surgery became the standard of care in hearing rehabilitation of patients with severe to profound sensorineural hearing loss. This procedure may alter the lives of children and adults enabling them to integrate with the hearing population. In the past, implantation was performed only in one ear, despite the fact that binaural hearing is superior to unilateral, especially in noisy conditions. Cochlear implantation may be performed sequentially or simultaneously. The "sensitive period" of time between hearing loss and implantation and between the two implantations, when performed sequentially, significantly influences the results. Shorter time spans between implantations improve the hearing results after implantation. Hearing success after implantation is highly dependent on the rehabilitation process which includes mapping, implant adjustments and hearing training. Bilateral cochlear implantation in children is recommended as the proposed procedure in spite of the additional financial burden.

    Thirteen eyes of 55 consecutive patients treated with brachytherapy for malignant melanoma of the choroid developed postirradiation cataracts. Cataract development was more common in older patients and in patients with larger and more anterior tumors. Eleven eyes had extracapsular cataract extraction and intraocular lens implantation. Initial visual improvement occurred in 91% of eyes, with an average improvement of 5.5 lines. Visual acuity was maintained at 20/60 or better in 55% of the eyes over an average period of follow-up of 24 months (range, 6 to 40 months). These data suggest that, visually, cataract extraction can be helpful in selected patients who develop a cataract after brachytherapy for malignant melanoma of the choroid.

  6. Surgical options for correction of refractive error following cataract surgery.

    2014-01-01

    Refractive errors are frequently found following cataract surgery and refractive lens exchange. Accurate biometric analysis, selection and calculation of the adequate intraocular lens (IOL) and modern techniques for cataract surgery all contribute to achieving the goal of cataract surgery as a refractive procedure with no refractive error. However, in spite of all these advances, residual refractive error still occasionally occurs after cataract surgery and laser in situ keratomileusis (LASIK) can be considered the most accurate method for its correction. Lens-based procedures, such as IOL exchange or piggyback lens implantation are also possible alternatives especially in cases with extreme ametropia, corneal abnormalities, or in situations where excimer laser is unavailable. In our review, we have found that piggyback IOL is safer and more accurate than IOL exchange. Our aim is to provide a review of the recent literature regarding target refraction and residual refractive error in cataract surgery.

    Full Text Available Shambhu D VarmaDepartment of Ophthalmology and Visual Sciences, Biochemistry and Molecular Biology, University of Maryland School of Medicine, Baltimore, MD, USAAbstract: Previous biochemical and morphological studies with animal experiments have demonstrated that caffeine given topically or orally to certain experimental animal models has significant inhibitory effect on cataract formation. The present studies were undertaken to examine if there is a correlation between coffee drinking and incidence of cataract blindness in human beings. That has been found to be the case. Incidence of cataract blindness was found to be significantly lower in groups consuming higher amounts of coffee in comparison to the groups with lower coffee intake. Mechanistically, the caffeine effect could be multifactorial, involving its antioxidant as well as its bioenergetic effects on the lens.Keywords: caffeine, cataract, cataract blindness, cataractogenic process, intraocular pressure, vision impairment

  8. The genetic and molecular basis of congenital cataract

    Full Text Available Congenital cataracts are one of the most treatable causes of visual impairment and blindness during infancy, with an estimated prevalence of 1 to 6 cases per 10,000 live births. Approximately fifty percent of all congenital cataract cases may have a genetic cause. All three types of Mendelian inheritance have been reported for cataract; however, autosomal dominant transmission seems to be the most frequent. The transparency and high refractive index of the lens are achieved by the precise architecture of the fiber cells and the homeostasis of the lens proteins in terms of their concentration, stability, and supramolecular organization. Research on hereditary congenital cataract led to the identification of several classes of candidate genes that encode proteins such crystallins, lens specific connexins, aquaporine, cytoskeletal structural proteins, and developmental regulators. The purpose of this study was to review the literature on the recent advances made in understanding the molecular genetic basis of congenital cataracts.

    Full Text Available AIM: To observe the diopter after cataract surgery for vision gain in high myopia and its effect on visual outcomes. METHODS: Sixty(120 eyeshigh myopia combined with cataract cases received phacoemulsification and intraocular lens implantation in our hospital were retrospective studied. The patients were divided into three groups based on postoperative diopter: -1.0~-2.0D(group A, -2.25~-3.0D(group Band -3.25~-4.0D(group C. The uncorrected distance visual acuity(UCDVA, best corrected distant visual acuity(BCDVA, uncorrected near visual acuity(UCNVAand questionnaire of Activities of Daily Vision Scale(ADVSwere collected to assess the vision gain at 3mo after cataract surgery. RESULTS: At 3mo after surgery, UCDVA of group A was better than that of group B, and UCDVA of group B was better than that of group C. There were no differences in BCDVA among groups. There were significant differences between the three groups' UCNVA, it was best for the group C, followed by the group B, group A was the worst. For questionnaire, no difference was observed in patients' satisfactory for surgical results, but a significant difference was detected in postoperative glasses wearing frequency between groups. CONCLUSION:For cataract surgery in high myopia combined cataract, postoperative diopter should be calculated based on patients' daily requirements. For patients had not used to wearing glasses and near distant working condition, it's appropriated to reserve a minor degree of myopia. Conversely, for patients require near distant working and received wearing moderate and low hyperopia mirror, higher degree of myopia can be reserved.

  10. Are entry criteria for cataract surgery justified?

    Directory of Open Access Journals (Sweden)

    Daniel Böhringer

    Full Text Available PURPOSE: The German Ophthalmological Society (GOS recently proposed surgical entry criteria, i.e. 300 cataract surgeries. We herein correlate the surgical hands-on experience with the risk of posterior capsule ruptures in order to assess whether this number is appropriate. METHODS: We identified all cataract operations that had been performed at the University Eye Hospital Freiburg since 1995. For each surgeon, we assigned a running number to his/her procedures in the order they had been performed. Thereafter, we excluded all combined procedures and the second eyes. We then selected the 5475 surgical reports between November 2008 and November 2012 for detailed review. We additionally classified each surgery into low- vs. high- à priori risk for posterior capsule ruptures. We fitted a multifactorial logistic regression model to assess the GOS recommendation of 300 surgeries under supervision. In the low-risk group, we additionally visualized the 'typical' learning curve by plotting the posterior capsule ruptures against the respective rank numbers. RESULTS: The odds ratio for posterior capsule ruptures of 'learning-mode' (one of the respective surgeon's 300 first procedures vs. the non-learning-mode was 3.8 (p<0.0001. By contrast, classification into the low-risk group lowered the risk of posterior capsule ruptures three fold (p<0.0001. According to the low-risk plot, the surgeons started with a complication rate of 4% and continuously improved towards 0.5% after 1500 operations. Thereafter, the rate increased again and stabilized around one percent. CONCLUSION: The learning curve with respect to posterior capsule ruptures is surprisingly flat. The GOS entry criterion of 300 cataract procedures is therefore most likely justified. Careful selection of low-risk patients for the training surgeons may help in reducing the rate of posterior capsule ruptures during training.

    Full Text Available Purpose: To develop an uniform method of the treatment for patients with progressive keratoconus (stage 1‑2 and cataract. Patients and methods: 4 patients (5 eyes with cataract and progressive keratoconus stage 1‑2 were enrolled in the study. Mean age was 42 years. In all patients, standard ophthalmic examination as well corneal topography, anterior segment optical coherence tomography, biometry, and IOL power calculations using IOLMaster were performed. Mean uncorrected visual acuity (UCVA was 0.1 while mean best-corrected visual acuity (BCVA was 0.4. Surgical technique included two steps. The first step was the creation of corneal tunnels with femtosecond laser with subsequent phaco and monofocal aspheric IOL implantation. The second step (1‑2 weeks later was the implantation of intrastromal ring segments based on corneal topography and corneal crosslinking.Results: After the first step, all patients had myopic refraction (from –1.0 D to –2.5 D. Cylindrical component was almost unchanged. After the second step, the patients reported the vision improvement, mainly due to UCVA. Both spherical (myopic and cylindrical components decreased, mainly due to the steep meridian. After the treatment, optical power of the cornea decreased, mainly due to the steep meridian. UCVA was 0.6 or more in 60 % of cases, final BCVA was 0.8‑1.0 in 80 % of cases. Neither intraoperative nor postoperative (follow-up was 2 years complications were observed.Conclusions: Combined phaco and prior creation of corneal tunnels with subsequent intrastromal ring segment implantation and crosslinking in patients with cataract and progressive keratoconus stage 1‑2 is safe, provides good predictable outcome and significantly reduces rehabilitation period.

Ma te ri al and Met hod: We retrospectively evaluated 51 previously vitrectomized eyes of 51 patients who had undergone phacoemulsification and intraocular lens (PHACO+IOL implantation surgery. PHACO+IOL surgery was performed in our clinic between October 2008 and May 2011. Intraoperative complications and postoperative best-corrected visual acuity (BCVA outcomes were analyzed. Re sults: In this study, 31 out of 51 eyes had posterior subcapsular cataract. Cataract surgery was performed after a mean of 21.39±26.4 (6- 120, median 10.75 months following PPV. Mean preoperative and postoperative BCVA was measured to be 1.52±0.88 logMAR and 0.74±0.73 logMAR, respectively. In 25 eyes which had been filled with silicon oil, mean BCVA was 1.95±0.91 logMAR preoperatively and 1.15±0.84 logMAR postoperatively. In 18 (35.3% eyes which had been filled with sulfur hexafluoride tamponade, mean BCVA was 1.17±0.47 logMAR preoperatively and 0.38±3.6 logMAR postoperatively. Peroperative zonular dialysis with instable deep anterior chamber occurred in two eyes, and posterior capsular tear occurred in one eye. Four eyes had Nd:YAG capsulotomy due to the posterior capsular opacity during the follow-up period. Dis cus si on: Despite the well-known difficulties encountered in vitrectomized eyes such as zonular weakness, increased mobility of the lens-iris diaphragm, posterior capsular instability and posterior capsular plaques, phacoemulsification in vitrectomized eyes proved to be a safe surgery, and increase in visual acuity can be achieved.

    Aims: To describe liquefied after cataract (LAC) and its surgical management following an uneventful phacoemulsification with posterior chamber in-the-bag intraocular lens (IOL) implantation and continuous curvilinear capsulorrhexis (CCC). Design: Interventional case series. Materials and Methods: Eleven patients with LAC, following uneventful phacoemulsification with CCC and in-the-bag IOL implantation were enrolled. After the basic slit lamp examination, each case was investigated with Scheimpflug photography and ultrasound biomicroscopy (UBM). Each case was treated with capsular lavage. Biochemical composition of the milky fluid was evaluated and ring of anterior capsular opacity (ACO) was examined under electron microscope. Results: All 11 cases presented with blurring of vision after 6-8 years of cataract surgery with IOL implantation. All cases had IOL microvacuoles, 360° anterior capsule, and anterior IOL surface touch along with ACO, ring of Soemmering, and posterior capsule distension filled with opalescent milky fluid with whitish floppy or crystalline deposits. Biochemically, the milky fluid contained protein (800 mg/dl), albumin (100 mg/dl), sugar (105 mg/dl), and calcium (0.13%) and was bacteriologically sterile. Histologically, the dissected ACO showed fibrous tissue. All cases were successfully treated with capsular lavage with good visual recovery and with no complication. There was no recurrence of LAC during 2 years postoperative follow-up in any of the cases. Conclusions: LAC is a late complication of standard cataract surgery. It may be a spectrum of capsular bag distension syndrome (CBDS) without shallow anterior chamber and secondary glaucoma. Capsular bag lavage is a simple and effective treatment for LAC and a safe alternative to neodymium-doped yttrium aluminum garnet (Nd-YAG) capsulotomy. PMID:24881605

    Full Text Available Purpose: The aim was to assess the impact of cataract surgeries in reducing visual disabilities and factors influencing it at three institutes of India. Materials and Methods: A retrospective chart review was performed in 2013. Data of 4 years were collected on gender, age, residence, presenting a vision in each eye, eye that underwent surgery, type of surgery and the amount the patient paid out of pocket for surgery. Visual impairment was categorized as; absolute blindness (no perception of light; blind (<3/60; severe visual impairment (SVI (<6/60-3/60; moderate visual impairment (6/18-6/60 and; normal vision (≥6/12. Statistically analysis was performed to evaluate the association between visual disabilities and demographics or other possible barriers. The trend of visual impairment over time was also evaluated. We compared the data of 2011 to data available about cataract cases from institutions between 2002 and 2009. Results: There were 108,238 cataract cases (50.6% were female that underwent cataract surgery at the three institutions. In 2011, 71,615 (66.2% cases underwent surgery. There were 45,336 (41.9% with presenting vision < 3/60 and 75,393 (69.7% had SVI in the fellow eye. Blindness at presentation for cataract surgery was associated to, male patients, Institution 3 (Dristi Netralaya, Dahod surgeries after 2009, cataract surgeries without Intra ocular lens implant implantation, and patients paying <25 US $ for surgery. Predictors of SVI at time of cataract surgery were, male, Institution 3 (OM, phaco surgeries, those opting to pay 250 US $ for cataract surgeries. Conclusion: Patients with cataract seek eye care in late stages of visual disability. The goal of improving vision related quality of life for cataract patients during the early stages of visual impairment that is common in industrialized countries seems to be non-attainable in the rural India.

    A 41-year-old man with liver cirrhosis of unknown aetiology for 6 years was admitted to our department to confirm the diagnosis of Wilson's disease. He consulted an ophthalmologist who suspected the presence of a sunflower cataract and Kayser-Fleischer ring. At admission, his liver function tests were modestly impaired (Child-Pugh C, 10 pts). Neurological examination was normal, but cognitive functions were mildly impaired. Based on the copper metabolism abnormalities and clinical manifestation, we diagnosed Wilson's disease (Ferenci score, 6 pts) and started treatment with d-penicillamine. Presenting the case we would like to emphasise the significance of the ophthalmological examination in Wilson's disease diagnosis.

    Full Text Available Abstract Background Trunk asymmetry (TA is a common phenomenon in children, but its incidence in juveniles is not known. The present cross sectional study reports TA in normal juveniles and provides data which describe the evolution of TA from early childhood to adolescence. Materials and methods The scoliometer readings in both standing and sitting forward bending position (FBP of 3301 children, (1645 boys, and 1656 girls aged from 3 to 9 years old were studied. TA was quantified by measuring angle of trunk rotation (ATR and children were categorized as symmetric (ATR = 0°, mild asymmetric (ATR 1° – 6° and severely asymmetric (ATR ≥ 7°. The difference of TA between standing and sitting FBP as well as differences between boys and girls in frequency of TA were also calculated. The scoliometer readings were analyzed by age to reveal at which age the juvenile pattern of TA changes into the adolescent one. Results 74.2% of boys and 77% of girls were symmetric (ATR = 0° in the thoracic region in standing FBP, while 82.7% of boys and 84.1% of girls were symmetric in the thoracic region in sitting FBP. Juvenile girls are more symmetric than boys but severe TA was found almost the same between the two genders. A significant reduction in the frequency of mild TA from standing into sitting FBP, in all the examined regions in both boys and girls was found, but in severe TA this reduction is very small. Analysing scoliometer readings by age it appears that significant TA changes take place between 8–9 years of age for boys and between 6–7 and 8–9 years for girls. TA in boys is changing into the adolescent pattern at a later age than in girls. Conclusion Juveniles were found more symmetric than adolescents, who were studied previously in a different study. Furthermore, juvenile girls were found more symmetric than boys. Juvenile TA pattern seems to be in accordance with the higher incidence of juvenile idiopathic scoliosis in boys. Furthermore

  2. Juvenile Incarceration and Health.

    Barnert, Elizabeth S; Perry, Raymond; Morris, Robert E

    2016-03-01

    Addressing the health status and needs of incarcerated youth represents an issue at the nexus of juvenile justice reform and health care reform. Incarcerated youth face disproportionately higher morbidity and higher mortality compared to the general adolescent population. Dental health, reproductive health, and mental health needs are particularly high, likely as a result of lower access to care, engagement in high-risk behaviors, and underlying health disparities. Violence exposure and injury also contribute to the health disparities seen in this population. Further, juvenile incarceration itself is an important determinant of health. Juvenile incarceration likely correlates with worse health and social functioning across the life course. Correctional health care facilities allow time for providers to address the unmet physical and mental health needs seen in this population. Yet substantial challenges to care delivery in detention facilities exist and quality of care in detention facilities varies widely. Community-based pediatricians can serve a vital role in ensuring continuity of care in the postdetention period and linking youth to services that can potentially prevent juvenile offending. Pediatricians who succeed in understanding and addressing the underlying social contexts of their patients' lives can have tremendous impact in improving the life trajectories of these vulnerable youth. Opportunities exist in clinical care, research, medical education, policy, and advocacy for pediatricians to lead change and improve the health status of youth involved in the juvenile justice system.

    Congenital cataracts can occur as a non-syndromic isolated ocular disease or as a part of genetic syndromes accompanied by a multi-systemic disease. Approximately 50% of all congenital cataract cases have a heterogeneous genetic basis. Here, we describe three generations of a family with an autosomal dominant inheritance pattern and common complex phenotypes, including bilateral congenital cataracts, short stature, macrocephaly, and minor skeletal anomalies. We did not find any chromosomal aberrations or gene copy number abnormalities using conventional genetic tests; accordingly, we conducted whole-exome sequencing (WES) to identify disease-causing genetic alterations in this family. Based on family WES data, we identified a novel BRD4 missense mutation as a candidate causal variant and performed cell-based experiments by ablation of endogenous BRD4 expression in human lens epithelial cells. The protein expression levels of connexin 43, p62, LC3BII, and p53 differed significantly between control cells and cells in which endogenous BRD4 expression was inhibited. We inferred that a BRD4 missense mutation was the likely disease-causing mutation in this family. Our findings may improve the molecular diagnosis of congenital cataracts and support the use of WES to clarify the genetic basis of complex diseases. PMID:28076398

    Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease of childhood, with JIA-associated uveitis its most common extra-articular manifestation. JIA-associated uveitis is a potentially sight-threatening condition and thus carries a considerable risk of morbidity. The aetiology of the condition is autoimmune in nature with the predominant involvement of CD4(+) T cells. However, the underlying pathogenic mechanisms remain unclear, particularly regarding interplay between genetic and environmental factors. JIA-associated uveitis comes in several forms, but the most common presentation is of the chronic anterior uveitis type. This condition is usually asymptomatic and thus screening for JIA-associated uveitis in at-risk patients is paramount. Early detection and treatment aims to stop inflammation and prevent the development of complications leading to visual loss, which can occur due to both active disease and burden of disease treatment. Visually disabling complications of JIA-associated uveitis include cataracts, glaucoma, band keratopathy and macular oedema. There is a growing body of evidence for the early introduction of systemic immunosuppressive therapies in order to reduce topical and systemic glucocorticoid use. This includes more traditional treatments, such as methotrexate, as well as newer biological therapies. This review highlights the epidemiology of JIA-associated uveitis, the underlying pathogenesis and how affected patients may present. The current guidelines and criteria for screening, diagnosis and monitoring are discussed along with approaches to management.

    Postoperative endophthalmitis is a very devastating complication and every step should be taken to reduce its occurrence. Unattended air conditioning filter systems are often the culprits and regular maintenance of the filters is of paramount importance. Shedders of pathogenic organisms amongst the theater personnel should be identified by regular screening and should be promptly treated. In addition to the use of Povidone iodine 5% solution in the conjunctival sac few minutes prior to surgery, proper construction of wound, injectable intraocular lenses, use of prophylactic intracameral antibiotics or prophylactic subconjunctival antibiotic injection at the conclusion of cataract surgery, placing a patch after the surgery for at least 4 h and initiating topical antibiotics from the same day of surgery helps to lower the frequency of postoperative endophthalmitis. Intraoperative posterior capsule rupture and anterior vitrectomy are risk factors for acute endophthalmitis, and utmost care to prevent posterior capsular rent should be taken while performing cataract surgery. Also, in case of such complication, these patients should be closely monitored for early signs of endophthalmitis in the postoperative period. In the unfortunate event of endophthalmitis the diagnosis should be prompt and treatment must be initiated as early as possible.

    Full Text Available Cataract surgery is most common in human surgery and comprises 80% of eye surgery programs. Owing to sophisticated technologies, it has become a routine surgery with lowered complications rate; hence, the functional outcome is more conditioned by operative trauma. The aim of this study was to demonstrate the significance of specular microscopy in the evaluation of operative trauma during extra-capsular cataract extraction (ECCE and phacoemulsification (P, in a controlled environment. The study included 100 consecutive patients who met the established criteria, and groups were formed according to the type of surgery by the assignment of successive numbers from a random number table. Examination and photographs of the corneal endothelium, as well as pachymetry were performed on Keeler-Konan Poclington Specular Microscope (KSP. The obtained results revealed significant dissimilarity in endothelial cell reduction (9.17% in group E, and 4.72% in group P, which generated statistically significant correlation of pre-operative and post-operative pachymetry in the group E (p=0.0004. On the basis of the results obtained by specular microscopy, it was concluded that under the same conditions phacoemulsification caused reduced operative trauma of the corneal endothelium.

    Full Text Available Purpose. To determine how different grades of cataract affect sensitivity threshold and saccadic reaction time (SRT in eye movement perimetry (EMP. Methods. In EMP, the visual field is tested by assessing the saccades that a subject makes towards peripheral stimuli using an eye tracker. Forty-eight cataract patients underwent pre- and postoperative EMP examination in both eyes. The subjects had to fix a central stimulus presented on the eye tracker monitor and to look at any detected peripheral stimulus upon its appearance. A multilevel mixed model was used to determine the factors that affected the sensitivity threshold and the SRT as a function of cataract grade. Results. We found no effect of cataract severity (LOCS III grades I through IV on SRT and the sensitivity thresholds. In cataract of LOCS III grade V, however, we found an increase by 27% and 21% (p<0.001, respectively, compared to the SRT and the sensitivity threshold in LOCS III grade I. Eyes that underwent cataract surgery showed no change in mean SRTs and sensitivity thresholds after surgery in LOCS III grade IV and lower. Conclusion. The present study shows that EMP can be readily used in patients with cataract with LOCS III grade IV and below.

    Full Text Available Background: Cataract has emerged as the most important cause of blindness in children worldwide, and has been one of the priorities of VISION 2020, the global initiative to eliminate avoidable blindness by 2020. More than 2500 children are estimated to be blind from cataract in Madagascar. The aim of this study was to investigate the burden and causes of pediatric cataract in a busy eye clinic in Madagascar and measure service delivery. Materials and Methods: This was a retrospective case series of all children aged 15 and below, receiving cataract surgery at the busiest eye clinic in Southern Madagascar. Data on all children operated on at the eye clinic between September 1999 and July 2009 were retrieved from theatre logs and patient charts. Results: One hundred and fourteen eyes of 86 children were operated on during the study period, with congenital cataract being the diagnosis in 53.5% of the children. For the catchment area of 5.8 million inhabitants 2.7% of incident cases of non-traumatic pediatric cataracts had surgery, with a mean CCSR per year for the entire catchment area of 1.1/million population. Conclusions: The Southern part of Madagascar is underserved for pediatric cataract surgical services, hence the need for a childhood blindness program.

    2016-02-01

    Congenital cataract is the common cause of visual disability in children. Nearly one third of congenital cataract cases may have a related genetic mutation. With the development of molecular genetics, especially gentechnik, more and more genes, such as crystallin genes, membrane protein genes, eytoskeletal protein genes and regulatory protein genes have been confirmed to participate in the process of congenital cataract. Furthermore, crystallin genes account for most of these genes and the crystallin has the highest amount of the whole protein in lens.It has been found that nearly one hundred mutations in crystallin genes are associated with the onset of congenital cataract. Researchers are exploring how these mutations further affect the function of cellular biology and eventually lead to cataract. Although more and more research results gradually reveal the pathogenesis of congenital cataract from the level of gene and protein, the specific pathogenesis is still unclear. The recent progression about inherited congenital cataract related with crysallin genes is summarized in this review.

    In sub-Saharan Africa, cataract surgical services are highly inadequate and surgical uptake for cataract is low. This paper describes cataract surgical uptake among older adults in Ghana. This work was based on World Health Organization's multi-country Study on global Ageing and adult health (SAGE), conducted in six countries including Ghana. Wave one of SAGE in Ghana was conducted in 2007-2008 as collaboration between WHO and Department of Community Health, University of Ghana Medical School. A nationally representative sample of 5571 older adults (≥50 years) and a small sample of persons 18-49 years were interviewed. Data was obtained on uptake of cataract surgery in older adults and analyzed using descriptive measures and chi square for associations in categorical outcome measures. Overall surgical uptake was 48.9% among older adults and was slightly higher among older men (49.1%) than women (48%). Cataract surgical uptake was relatively higher in the 60-69 years group (55%), urban residents (52.6%) and those living without partners (50%). Educational and income levels of older persons did not affect cataract surgical uptake. Regional differences in cataract surgical uptake existed; was less than 60% in all ten regions (except one), and the two regions with most self-reported cataracts (Ashanti and Greater Accra) had less than 50% uptake. Intensive public education, engagement of community groups and increased access to cataract surgery at health facilities and outreach services need consideration at national/sub-national levels. Further investigations to garner equity in national eye care efforts are recommended.

    Objective To estimate the prevalence of cataract, surgicalcoverage rate and the bilateral cataract-blindness burden among adults aged 50 or above in Shunyi District of Beijing, China, for evaluating the cataract status and the efficacy of the prevention blindness program in more than 10 years. Methods Cluster sampling was used in randomly selected individuals aged 50 years or older in 28 villages in Shunyi District in fall, 1996. 5 084 individuals received visual acuity test and eye examination, including lens examination by slit lamp. The cataract operation status was also evaluated. Results The prevalence of cataract was 23.31% among adults aged 50 or above. The prevalence of cataract was increasing by aging. The prevalence of cataract in women and illiterates was significantly higher statistically. The cataract surgical rate had been increasing since 1984. When the bilateral pinhole vision <3/60 was defined as the blindness criterion, the cataract blindness surgical coverage rate was 56.36%, and the bilateral cataract-blindness burden was 1.63%. When the bilateral presenting vision <6/60 was defined as the blindness criterion, the cataract blindness surgical coverage rate was 47.79%, and the bilateral cataract-blindness burden was 2.22%. The cataract surgical coverage rates were much lower and the bilateral cataract-blindness burden much higher in women, illiterates and persons aged 70 or above. Conclusions The prevalence of cataract is higher and bilateral cataract-blindness burden is heavier in elder individuals. Cataract blindness is still a serious public health problem in elder, women and illiterates after the prevention blindness program having been actively conducted for more than ten years.%目的 调查北京市顺义区50岁及以上人群中白内障患病率、白内障盲人手术覆盖率和白内障盲人社会负担率,以此了解白内障的患病状况及评价10余年来该区实施以白内障手术治疗为主的防盲治盲工作的

    Application of femtosecond lasers to cataract surgery has added unprecedented precision and reproducibility but ocular safety limits for the procedure are not well-quantified. We present an analysis of safety during laser cataract surgery considering scanned patterns, reduced blood perfusion, and light scattering on residual bubbles formed during laser cutting. Experimental results for continuous-wave 1030 nm irradiation of the retina in rabbits are used to calibrate damage threshold temperatures and perfusion rate for our computational model of ocular heating. Using conservative estimates for each safety factor, we compute the limits of the laser settings for cataract surgery that optimize procedure speed within the limits of retinal safety.

    To survey the surgical routines with regards to prophylactic strategies in a sample of Italian hospitals and compare these with European Society for Cataract and Refractive Surgery (ESCRS) guidelines. Six private and 18 public hospitals were included in this clinical-based retrospective study. The overall volume of cataract operations in the 24 centers in 2013 was 43,553. Main outcome measure was incidence of endophthalmitis per 1,000. An incidence of less than 0.13% was considered acceptable. Our study provides the first Italian data on the use of intracameral antibiotics in cataract surgery as recommended by the ESCRS. Thirteen centers (54%) used intracameral cefuroxime at the end of surgery. Of the 13 centers that used cefuroxime, 8 (62%) had an incidence of endophthalmitis less than 0.13%. Of the 7 (29%) centers that did not use intracameral cefuroxime, all had an endophthalmitis rate of greater than 0.13%. This difference was statistically significant (p<0.05). Among the 4 centers not included, 2 used vancomycin in the infusion bottle, 1 a fluoroquinolone, and the last a combination of antibiotics. The majority of surgeons (71%) used preoperative antibiotic eyedrops, but this measure was not shown to be significantly protective. Slightly more than half of the centers surveyed in this study adhered to the recommendations of the ESCRS and routinely employed prophylactic intracameral cefuroxime. An incidence of endophthalmitis greater than 0.13% was encountered significantly more frequently among centers that did not employ intracameral cefuroxime.

    The combination of Turner syndrome with other genetic disorders such as congenital cataract has been reported, but its association with a congenital form with autosomal dominant inheritance and incomplete penetrance has not been previously reported in the literature. There are no reports on its presentations with rearrangements on chromosome 17. We report the exceptional case of a 20 months old girl with a constellation of major and minor anomalies, diagnosed with mosaic Turner syndrome by isochromosome Xq associated with a microduplication 17p13.3p13.2, who also had bilateral congenital nuclear cataract autosomal dominant with incomplete penetrance. We reviewed in the literature the origin and cause of these genetic alterations and we provided an approach to the hypothesis of the pathogenesis of the association of two of these genetic disorders in the same patient.

  18. Early acute aseptic iritis after cataract extraction.

    Science.gov (United States)

    Allen, H F; Grove, A S

    1976-01-01

    Severe iritis which occurs within the first five days after cataract extraction may be categorized as (1) bacterial endophthalmitis, (2) toxic iritis, or (3) aseptic iritis. These entities can sometimes be distinguished because of their clinical features. If bacterial endophthalmitis is suspected, anterior chamber paracentesis should be considered and appropriate antibiotic treatment should be initiated. Acute iritis may result from the introduction of toxic agents into the eye, and may follow the use of products sterilized with ethylene oxide. Early acute aseptic iritis probably occurs more often than has previously been recognized. Response to intensive anti-inflammatory treatment is usually prompt and dramatic. The judicious use of cryoextraction and the careful manipulation of intraocular tissues may minimize the incidence and the severity of postoperative inflammation.

    2011-01-01

    Full Text Available To evaluate the safety, efficacy, advantages, and limitations of femtosecond laser-assisted cataract surgery through a review of the literature. A PubMed search was conducted using topic-appropriate keywords to screen and select articles. Initial research has shown appropriate safety and efficacy of femtosecond laser-assisted cataract surgery, with improvements in anterior capsulotomy, phacofragmentation, and corneal incision. Limitations of these studies include small sample size and short-term follow-up. Cost-benefit analysis has not yet been addressed. Preliminary data for femtosecond laser-assisted cataract surgery shows appropriate safety and efficacy, and possible advantage over conventional cataract surgery. Questions to eventually be answered include comparisons of long-term postoperative complication rates-including infection and visual outcomes-and analysis of contraindications and financial feasibility.

    To demonstrate the feasibility of a new methodology for cataract hardness characterization and automatic classification using ultrasound techniques, different cataract degrees were induced in 210 porcine lenses. A 25-MHz ultrasound transducer was used to obtain acoustical parameters (velocity and attenuation) and backscattering signals. B-Scan and parametric Nakagami images were constructed. Ninety-seven parameters were extracted and subjected to a Principal Component Analysis. Bayes, K-Nearest-Neighbours, Fisher Linear Discriminant and Support Vector Machine (SVM) classifiers were used to automatically classify the different cataract severities. Statistically significant increases with cataract formation were found for velocity, attenuation, mean brightness intensity of the B-Scan images and mean Nakagami m parameter (p hardness characterization and automatic classification.

    The authors have developed a new method for removal of congenital cataract in children, by taking into account its clinical forms, namely, combined laser instrumental extraction including YAG-laser anterior capsular rhexis, followed by removal of lens debris by the aspiration-irrigation technique. A differential technology of YAG-laser anterior capsular rhexis has been developed, by taking into account of age-specific features of the lens and eyes in children. The optimum energy modes and techniques have been defined for different clinical forms of congenital forms of congenital cataracts. An analysis of the outcomes and complications of extraction of congenital cataracts has indicated that the authors' combined laser instrumental extract procedure (75 operations) assures the better quality of anterior capsular excision, improves optical and functional effects, and reduces the frequency of some complications as compared to the routine instrumental procedure (107 operations) (p instrumental extraction is indicated for the treatment of any forms of congenital cataracts in children.

    Full Text Available Objective: To assess cataract incidence in the cohort of workers occupationally exposed to prolonged radiation. Material and Methods: Cataract incidence was studied in the cohort of workers of the first Russian nuclear enterprise — the Mayak, who were firstly employed at one of the main facilities (reactors, radiochemical and plutonium production plants in 1948‑1958 and followed up to the end of 2008 (12210 persons. Total of 3100 cataract cases were registered in the study cohort. All cataract cases were reviewed and verified by experts; the study included only confirmed senile cataracts. All workers of the study cohort were exposed to external gamma-rays; mean cumulative dose from external gamma-rays was 0.91±0.01 Gy in males and 0.65±0.01 Gy in females. Statistical analysis provided non-standardized and standardized incidence rates per 100 000 workers. Standardization by sex and age was performed by indirect method using internal reference.Results: 2523 cases of senile cataract were included in the study. Mean age of cataract diagnosis was 62.88±0.26 years in males and 64.88±0.28 years in females. Standardized incidence rates of cataract in females were significantly higher as compared to males and increased with workers age. Comparison between the subcohorts of workers with / without diagnosed cataracts demonstrated that among workers with cataracts the proportions of the following groups of workers were significantly higher: workers employed before 1954; workers employed at reactors; smoking workers; workers with the smoking index exceeding 20 pack*years; workers who consumed alcohol; workers with excessive body weight; workers with glaucoma and arterial hypertension. Moreover the mean cumulative dose from external gamma-rays and / or neutron exposure was significantly higher in the subcohort of workers diagnosed with cataracts than that in the subcohort of workers free of the disease.

    Full Text Available Cataract is a principal cause of blindness in the world and is characterized by clouding of eye’s natural lens. Surgery is the major therapeutic step taken to cure cataract; however, it is having its own limitations and complications such as iris prolapse, raised IOP, infection, cystoid macular edema and posterior capsular opacification (PCO. So world is looking toward more robust and natural ways to prevent cataract. One of the important factors that can play a role in prevention of any and many diseases is diet of the people. The inclusion of certain naturally occurring food and nutraceuticals is coming up as a best alternative for curing cataract because of their presumed safety, potential nutritional and therapeutic effects. Some nutraceuticals can act as an anticataract agent through some or the other molecular mechanism if consumed by normal population deliberately or inadvertently.

    Hong-Wei Zhou; Li-Xin Xie

    2016-01-01

    Background:The endothelium should be carefully evaluated when choosing a surgical technique for cataract removal.Therefore,we aimed to study the effects of different cataract surgery techniques on endothelial cell loss in transplanted comeal grafts.Methods:A total of 54 patients who received complicated cataract surgery in post-penetrating keratoplasty (PKP) eyes at the Shandong Eye Institute between February 2001 and June 2014 were included,and clinical records were reviewed.Baseline demographic details,clinical characteristics,endothelial cell density (ECD),and best-corrected visual acuity (BCVA) were recorded.Wilcoxon rank-sum test and Wilcoxon signed-rank test were used to test the equality of medians.A regression model was constructed to compare the reduced rate of ECD.Results:Of the 54 eyes included in this study,extracapsular cataract extraction (ECCE) was performed in 34 eyes of 33 patients (ECCE group) whereas phacoemulsification was performed in 20 eyes of 20 patients (phacoemulsification group).There was no significant difference in the median age (P =0.081) or preoperative ECD (P =0.585) between the two groups.At 6 months after cataract surgery,ECD in ECCE group was significantly higher than that in phacoemulsification group (P =0.043).In addition,the endothelial cell loss rate in ECCE group was significantly lower than that in phacoemulsification group at 2 months (P =0.018),4 months (P < 0.001),and 6 months (P < 0.001) after cataract surgery.Endothelial cell loss rate after cataract surgery increased over the 6-month study duration in both ECCE group (P < 0.00 l) and phacoemulsification group (P < 0.001),but phacoemulsification resulted in a greater reduction in ECD than that of ECCE in transplanted corneal grafts (P < 0.001).There was no significant difference in postoperative BCVA between the two groups (P =0.065).Conclusion:ECCE is more suitable than phacoemulsification in cataract surgery in complicated cataract after PKP.

    Objective We investigated whether previously reported single nucleotide polymorphisms (SNPs) of EPHA2 in European studies are associated with cataract in India. Methods We carried out a population-based genetic association study. We enumerated randomly sampled villages in two areas of north and south India to identify people aged 40 and over. Participants attended a clinical examination including lens photography and provided a blood sample for genotyping. Lens images were graded by the Lens Opacification Classification System (LOCS III). Cataract was defined as a LOCS III grade of nuclear ≥4, cortical ≥3, posterior sub-capsular (PSC) ≥2, or dense opacities or aphakia/pseudophakia in either eye. We genotyped SNPs rs3754334, rs7543472 and rs11260867 on genomic DNA extracted from peripheral blood leukocytes using TaqMan assays in an ABI 7900 real-time PCR. We used logistic regression with robust standard errors to examine the association between cataract and the EPHA2 SNPs, adjusting for age, sex and location. Results 7418 participants had data on at least one of the SNPs investigated. Genotype frequencies of controls were in Hardy-Weinberg Equilibrium (p>0.05). There was no association of rs3754334 with cataract or type of cataract. Minor allele homozygous genotypes of rs7543472 and rs11260867 compared to the major homozygote genotype were associated with cortical cataract, Odds ratio (OR) = 1.8, 95% Confidence Interval (CI) (1.1, 3.1) p = 0.03 and 2.9 (1.2, 7.1) p = 0.01 respectively, and with PSC cataract, OR = 1.5 (1.1, 2.2) p = 0.02 and 1.8 (0.9, 3.6) p = 0.07 respectively. There was no consistent association of SNPs with nuclear cataract or a combined variable of any type of cataract including operated cataract. Conclusions Our results in the Indian population agree with previous studies of the association of EPHA2 variants with cortical cataracts. We report new findings for the association with PSC which is particularly prevalent

    This literature review is aimed at the evaluation of the potential for cataract prevention in Europe. It was performed using PubMed with Mesh and free-text terms. Studies included were (i) performed on a population of Caucasian origin at an age range of 40-95 years, (ii) cataract was clinically verified, (iii) drug record of prescriptions, their indication, a record of every diagnosis, dosage and quantity of prescribed medicine were available, (iv) sample size >300 and (v) published between 1990 and 2009. The results of 29 articles were reviewed. Former [3.75 (2.26-6.21)] or current smoking [2.34 (1.07-5.15)], diabetes of duration >10 years [2.72 (1.72-4.28)], asthma or chronic bronchitis [2.04 (1.04-3.81)], and cardiovascular disease [1.96 (1.22-3.14)] increased the risk of cataract. Cataract was more common in patients taking chlorpromazine during ≥90 days with a dosage ≥300 mg [8.8 (3.1-25.1)] and corticosteroids >5 years [3.25 (1.39-7.58)] in a daily dose >1600 mg [1.69 (1.17-2.43)]. Intake of a multivitamin/mineral formulation [2.00 (1.35-2.98)] or corticosteroids [2.12 (1.93-2.33)] also increased the risk of cataract. Corticosteroids applied orally [3.25 (1.39-7.58)], parenteral [1.56 (1.34-1.82)] or inhalational [1.58 (1.46-1.71)] lead to cataract more frequently than those applied topically: nasal [1.33 (1.21-1.45)], ear [1.31 (1.19-1.45)] or skin [1.43 (1.36-1.50)]. Outpatient cataract surgery was negatively associated with total cataract surgery costs, and chlorpromazine, corticosteroids and multivitamin/mineral formation increase the risk of posterior subcapsular cataract dependent on dose, treatment application and duration. This review presented a comprehensive overview of specific and general cataract risk factors and an update on most recent experimental studies and randomized control trials directed at cataract prevention. © 2012 The Authors.

    Bilateral chronic anterior uveitis is an extra-articular feature of juvenile idiopathic arthritis. Although figures vary, uveitis occurs in approximately 11%-13% of patients with this disease and is most commonly associated with the female gender, oligoarthritis, and presence of antinuclear antibodies. The disease has an insidious onset and is often asymptomatic. Managing patients with juvenile idiopathic arthritis-associated uveitis remains challenging as the disease may prove to be refractory to traditional treatment regimens. Stepwise immunomodulatory therapy is indicated, with new biologic drugs being used last in cases of refractory uveitis. Small scale studies and practice have provided the evidence to undertake randomized control trials to evaluate the efficacy, safety, and cost-effectiveness of anti-tumor necrosis factor-α therapies, such as infliximab and adalimumab. These have demonstrated promising results, with further data awaited from ongoing trials for adalimumab (as SYCAMORE and ADJUVITE trials). Lower grade evidence is supporting the use of newer biologics such as rituximab, daclizumab, tocilizumab, and abatacept in those cases refractory to anti-tumor necrosis factor-α therapy.

    2013-01-01

    Uveitis is the most common extra-articular manifestation of juvenile idiopathic arthritis, which is the most common systemic cause of uveitis in children. Known risk factors for uveitis include antinuclear antibody seropositivity, young age of arthritis onset, specific juvenile idiopathic arthritis subtype and short duration of disease. Risk markers for severe ocular disease include gender, age and complications at initial visit. Due to the risk for vision-compromising sequelae such as cataracts, band keratopathy, glaucoma, vision loss and blindness, an understanding of the risk factors for uveitis development and severe ocular disease is crucial to help prevent serious visual disability and complications. This paper reviews the pathogenesis of uveitis, known risk factors for uveitis development and severe visual outcome, and addresses the need for additional biomarkers of uveitis risk, prognosis and remission.

RESULTS: In whole city there were 16 operating microscopes, 43 slit lamp microscopes, 12 non-contact tonometers, 1 intraocular lens Master, 8 optical A/B type ultrasonic examination systems, 4 YAG lasers and 12 phacoemulsification instruments. There 15 doctors could complete cataract surgery independently, and 5 of them were phacoemulsification surgeons. The total number of completed cataract surgeries reached 6 211 eyes, containing 3 564 eyes for Phaco+IOL(57%(preoperative visual acuity ≥0.3 in Phaco+IOL1 were 1 520 eyes, 24%and 2 647 eyes for ECCE+IOL(43%(1 533 eyes in ECCE+IOL1, 25%. In various groups, off-blindness rate was 94.80%-100%, off-disability rate was 90.41%-100%, and 94.96%-100% received intraocular lens implantation, intraoperative complication rate was 1.00%-15.10%. CONCLUSION: The distribution of surgeons and equipments in the whole city is unbalanced, and the utilization rate of phaco equipment is low. The levels are different in various hospitals on surgical technique

    Full Text Available Abstract Background The most common causes of hemotympanum are therapeutic nasal packing, epistaxis, blood disorders and blunt trauma to the head. Hemotympanum is characterized as idiopathic, when it is detected in the presence of chronic otitis media. A rare case of spontaneous bilateral hemotympanum in a patient treated with anticoagulants is presented herein. Case presentation A 72-year-old male presented with acute deterioration of hearing. In the patient's medical history aortic valve replacement 1 year before presentation was reported. Since then he had been administered regularly coumarinic anticoagulants, with INR levels maintained between 3.4 and 4.0. Otoscopy revealed the presence of bilateral hemotympanum. The audiogram showed symmetrical moderately severe mixed hearing loss bilaterally, with the conductive component predominating. Tympanograms were flat bilaterally with absent acoustic reflexes. A computerized tomography scan showed the presence of fluid in the mastoid and middle ear bilaterally. Treatment was conservative and consisted of a 10-day course of antibiotics, anticongestants and temporary interruption of the anticoagulant therapy. After 3 weeks, normal tympanic membranes were found and hearing had returned to previous levels. Conclusion Anticoagulant intake should be included in the differential diagnosis of hemotympanum, because its detection and appropriate treatment may lead to resolution of the disorder.

    Juvenile ultracool dwarfs are late spectral type objects (later than ~M6) with ages between 10 Myr and several 100 Myr. Their age-related properties lie intermediate between very low mass objects in nearby star-forming regions (ages 1-5 Myr) and field stars and brown dwarfs that are members of the disk population (ages 1-5 Gyr). Kinematic associations of nearby young stars with ages from ~10-100 Myr provide sources for juvenile ultracool dwarfs. The lowest mass confirmed members of these groups are late-M dwarfs. Several apparently young L dwarfs and a few T dwarfs are known, but they have not been kinematically associated with any groups. Normalizing the field IMF to the high mass population of these groups suggests that more low mass (mainly late-M and possibly L dwarf) members have yet to be found. The lowest mass members of these groups, along with low mass companions to known young stars, provide benchmark objects with which spectroscopic age indicators for juvenile ultracool dwarfs can be calibrated and...

    We introduce a new type of multiple zeta functions, which we call bilateral zeta functions, analogous to the Barnes zeta functions. The bilateral zeta function is a periodic function and shares certain basic properties of Barnes zeta function. Especially, we prove that the bilateral zeta function has a nice Fourier series expansion and the Barnes zeta function can be expressed as a finite sum of bilateral zeta functions. By these properties of the bilateral zeta functions, We obtain simple pr...

    Full Text Available Background/Aim. Cataract surgery has become one of the safest procedures in medicine thanks to advances in technology and surgical techniques. Although minimal, we still witness different complications. The aim of this study was to compare visual outcome and complication rate in different techniques of cataract surgery, ie in cataract surgeries with various corneal incision width. Methods. The study included 3,457 consecutive patients, ie 4,670 eyes that had undergone cataract surgery. The used surgical techniques were: extracapsular cataract extraction, phacoemulsification/ forceps IOL implantation, phacoemulsification/ injector IOL implantation, microincision cataract surgery (MICS. Patient follow up was 6 months. Patients were evaluated for: visual aquity, corneal astigmatism, cellular reaction in the anterior chamber, IOL position. Results. Uncorrected visual aquity 30 days postoperatively was ≥ 0.5 in 30% of the eyes - ECCE; 54.7% of the eyes - phacoemulsification/forceps IOL implantation; 63.0% of the eyes - phacoemulsification/injector IOL implantation; 5/8 of the eyes - MICS. Endophthalmitis was detected in 0.15% of the eyes - ECCE and 0.1% of the eyes - phacoemulsification/forceps IOL implantation. In eyes with phacoemulsification/injector IOL implantation or microincision cataract surgery (MICS there were no cases of endophthalmitis. After a 6-month period intraocular lens were dislocated in 7.2% of the eyes - ECCE, and 0.6% of the eyes - phacoemulsification/PMMA IOL. There was no IOL dislocation in other surgical techniques. Conclusion. Shorter corneal incision implies less complications, less operative trauma, faster visual rehabilitation and better visual outcome.

    Eye lenses from human donors with and without Alzheimer's disease (AD) were studied to evaluate the presence of amyloid in cortical cataract. We obtained 39 lenses from 21 postmortem donors with AD and 15 lenses from age-matched controls provided by the Banco de Ojos para Tratamientos de la Ceguera (Barcelona, Spain). For 17 donors, AD was clinically diagnosed by general physicians and for 4 donors the AD diagnosis was neuropathologically confirmed. Of the 21 donors with AD, 6 had pronounced bilateral cortical lens opacities and 15 only minor or no cortical opacities. As controls, 7 donors with pronounced cortical opacities and 8 donors with almost transparent lenses were selected. All lenses were photographed in a dark field stereomicroscope. Histological sections were analyzed using a standard and a more sensitive Congo red protocol, thioflavin staining and beta-amyloid immunohistochemistry. Brain tissue from two donors, one with cerebral amyloid angiopathy and another with advanced AD-related changes and one cornea with lattice dystrophy were used as positive controls for the staining techniques. Thioflavin, standard and modified Congo red staining were positive in the control brain tissues and in the dystrophic cornea. Beta-amyloid immunohistochemistry was positive in the brain tissues but not in the cornea sample. Lenses from control and AD donors were, without exception, negative after Congo red, thioflavin, and beta-amyloid immunohistochemical staining. The results of the positive control tissues correspond well with known observations in AD, amyloid angiopathy and corneas with lattice dystrophy. The absence of staining in AD and control lenses with the techniques employed lead us to conclude that there is no beta-amyloid in lenses from donors with AD or in control cortical cataracts. The inconsistency with previous studies of Goldstein et al. (2003) and Moncaster et al. (2010), both of which demonstrated positive Congo red, thioflavin, and beta

    This report describes the induction of stationary radiation cataracts in postmetamorphic bullfrogs following ocular irradiation with a 10 Gy dose of X-rays. The eyes of non-irradiated animals and animals irradiated with 25 Gy served as controls. The 25 Gy irradiated lenses rapidly progressed to complete opacification (4+) by 26 weeks, while lenses exposed to 10 Gy advanced to the 2.5+ stage by 35 weeks and progressed no further. In the lower dose lenses, transparent cortex began to appear anteriorly and posteriorly between the capsule and opaque fibers at 45 weeks. As the clear fibers accumulated, the disrupted region came to occupy increasingly deeper cortex. Histologically, opacities in both groups were preceded by disorganization of the bow cytoarchitecture, meridional row disorganization, and the appearance in the lens epithelium of nuclear polymorphism, fragmented nuclei, micronuclei, clusters of nuclei, and abnormal mitotic figures. In the lenses exposed to the 25 Gy dose, this damage continued to worsen, so that the 4+ stage was characterized by extensive epithelial cell death, absence of the lens bow, degenerated fiber masses, and liquefied substrata. In contrast, prior to the appearance of transparent cortex in the 10 Gy group, the lens epithelial aberrations, arc of the bow, and meridional row disorganization were all observed to improve. Further, by 69 weeks, the lens epithelium appeared as a largely homogeneous population, and the meridional rows and the arc of the bow had become reestablished. (author).

    To evaluate the results of extracapsular cataract extraction (ECCE) and phacoemulsification (PHACO) performed in previously vitrectomized eyes. In this retrospective study, 56 vitrectomized eyes that had ECCE and 60 vitrectomized eyes that had PHACO were included in the study group while 65 eyes that had PHACO in the control group. The evaluated parameters were the incidence of intra-operative and postoperative complications (IPC) and visual outcomes. Chi-squared, independent samples and paired samples tests were used for comparing the results. Deep anterior chamber (AC) was significantly more common in the PHACO group of vitrectomized eyes (PGVE) and observed in eyes that had undergone extensive vitreous removal (p ECCE group and the PGVE (p > 0.05). Some of the intra-operative conditions such as posterior synechiae, primary posterior capsular opacification (PCO) and postoperative complications such as retinal detachment (RD), PCO were significantly more common in vitrectomized eyes than the controls (p ECCE group and the PGVE (p > 0.05). Deep AC is more common in eyes with extensive vitreous removal during PHACO than ECCE. Decreasing the bottle height is advised in this case. Except for this, the results of ECCE and PHACO are similar in previously vitrectomized eyes. Posterior synechiaes, primary and postoperative PCO and RD are more common in vitrectomized eyes than the controls.

    Full Text Available The aim of study was to achieve complete cortical cleanup and avoid problems related with sideport during Small Incision Cataract Surgery (SICS so as to have a good visual out come with minimal recovery period, and a better quality of life. After nucleus delivery, cortical cleanup is an important step in any cataract surgical procedure. Cortex especially subincisional area (11 to 1 o’clock is difficult to manage intraoperatively. Bimanual irrigation aspiration through two side ports, aspiration by J cannula, iris massage manoeuver, ice cream scoop manoeuver are various techniques of cortical matter aspiration. We acquired the technique of aspiration of subincisional cortex without using side port in all cases by paying attention on type of cataract, status of pupil, use of Adrenalin mixed BSS intraoperatively, Tunnel construction, Capsulorhexis size and capsular rim size at 12 o’clock. MATERIAL AND METHODS In this retrospective study of 1 year from 2013 to 2014, 60 patients (60 eyes aged 40 years or older attending the General Ophthalmic Department were included in the study group with another group of 60 patients (60 eyes as controls.

    an effective method for cataract surgery should be identified to combat cataract blindness. to study the surgical outcome of conventional extracapsular cataract extraction versus manual small-incision cataract surgery. a randomized clinical trial was carried out including one hundred eyes (88 patients) which were divided into two groups using systematic randomization: groups of conventional extracapsular cataract extractionwith posterior chamber intraocular lens (ECCE with PCIOL) implantation and manual small-incision cataract surgery (MSICS). The postoperative parameters/variables studied were the unaided and best-corrected visual acuity and astigmatism. epi info 2000 version statistical software was used for data analysis and calculation of relative risk, 95% CI and p value. The p value of less than 0.05 was considered as significant. in the immediate postoperative period, unaided visual acuity of =or> 6/18 was achieved in 24 subjects in MSICS group versus 7 in ECCE with PCIOL group (RR=2.05, 95% CI= 1.44 - 2.94, p = 0.0002), whereas the same at 6 - 8 weeks postoperatively was found in 28 and 22 subjects in those groups respectively (RR=1l.27, 95% CI=0.86-1.89, p=0.23). The astigmatism of =or> 2 at6 - 8 weeks was found in 35 and 17 subjects from the conventional and MSICS groups respectively ( R=2.28, 95% CI= 1.39-3.73, p=0.0002). both MSICS and conventional ECCE with PCIOL are safe and effective techniques for treatment of cataract patients. A more rapid recovery of good vision can be achieved with MSICS than with conventional ECCE with PCIOL in the immediate postoperative period.

Visual acuity, the refractive and the loss ratio of cornea endothelia cells were observed and compared after surgery. RESULTS: Uncorrected visual acuity of 33 eyes(10.78%and 76 eyes(24.84%was >1.0 in 7d and 3mo after MSICS. The loss ratio of cornea endothelia cells was 8.7%, The recursive of corneal astigmatism was on average 0.75D compared with preoperation. Uncorrected visual acuity of 63 eyes(20.59%and 92 eyes(30.07%was >1.0 in 7d and 3mo after phacoemulsification. The loss ratio of cornea endothelia cells was 21.67%. The average corneal astigmatism was -0.5DC and -0.45DC in MSICS group and Phaco group respectively, but 3mo after surgery, there was no significant difference on corneal astigmatism between the two groups(P>0.05.CONCLUSION: Due to the use of Phaco machine, the cost is higher in Phaco group, and the Phaco mechanical stimulation, injury, ultrasonic energy and perfusion solutions have effects on corneal endothelium, visual acuity recovery at early postoperative is slow. However, MSICS dose not use Phaco machine, works by hands, the cost is lower, and visual acuity recovery at early postoperative is faster.

  1. Nanotechnology for the Prevention and Treatment of Cataract.

    Cetinel, Sibel; Montemagno, Carlo

    2015-01-01

    The purpose of this article was to review recent advances in the applications of nanotechnology in cataract treatment and prevention strategies. A literature review on the use of nanotechnology for the prevention and treatment of cataract was done. Research articles about nanotechnology-based treatments and prevention technologies for cataract were searched on Web of Science, and the most recent advances were reported. Nonsteroid anti-inflammatory drugs, natural antioxidants, biologic and chemical chaperones, and chaperones such as molecules have found great application in preventing and treating cataracts. Current scientific research on new treatment strategies, which focuses on the biochemical basis of the disease, will likely result in new anticataract agents. However, none of the drug formulations will be approved for use unless efficient delivery is promised. Nanoparticle engineering together with biomimetic strategies enable the development of next-generation, more efficient, less complex, and personalized treatments. The only currently available treatment for cataracts, surgical replacement of the opacified lens, is not an easily accessible option in developing countries. New treatment strategies based on topical drugs would enable treatment to reach massive populations facing the threat of blindness and more effectively deal with the postsurgical complications. Nanotechnology plays a key role in improving drug delivery systems with enhanced controlled release, targeted delivery, and bioavailability to overcome diffusion limitations in the eye.

    Objective: To study the differences in expression of nuclear factor-κB (NF-κB) between human traumatic cataract and normal lenticular epithelial cells.Methods: Total RNA of anterior capsule specimens was taken under the microscope from normal cadaveric eyes donors and those suffering from traumatic cataract to make semi-quantitative RT-PCR and conduct analysis of differences in expression of NF-κB between them.Results: As compared with the mcan of 0. 8337 in normal control group, the expression equivalent of NF-κB was 0.9074 for the lenticular epithelial cells in traumatic cataract sufferers, and the differences are of noticeable significance (t = 2. 447, P < 0.05) accordingly.Conclusions: NF-κB is likely a kind of transcription factor necessary to maintain metabolism of normal lenticular epithelial cells. Higher NF-κ B available in the traumatic cataract sufferer's lenticular epithelial cells means NF-κB is of possible relevance to occurrence and development of traumatic cataract.

    Objective To compare ocular biometric values in angle closure glaucoma and cataract in senile population.Methods Ocular biometry was performed in eyes classified to have angle closure glaucoma (29 eyes) and senile cataract (31 eyes). Ocular biometry readings between two groups were compared and analyzed statistically. Intraocular pressure was also recorded before and after lens extraction.Results Anterior chamber depth was shallower in patients with angle closure glaucoma group [(1.79±0.56) mm] compared with senile cataract group [(2.69±0.40) mm] (P<0.01). Lens thickness was greater in angle closure glaucoma group [(5.30±0.61) mm] than that in senile cataract group [(3.84±0.61) mm] (P<0.01). Phacoemusification was performed in 5 patients with persistent acute attack of angle closure glaucoma. IOPs were controlled in all five cases after lens extraction.Conclusion Eyes with angle closure glaucoma seems to have significantly shallow anterior chamber and greater lens thickness compared to senile cataract eyes in the same age. Lens extraction might be effective in those cases with such anatomy features.

    We decided to evaluate the decrease in intraocular pressure six months after cataract surgery. We evaluated patients' IOP using an applanation tonometer. The patients then underwent cataract surgery. Six months after cataract surgery, we reevaluated the IOP by the same method, and we determined the post-operative change. Among the 147 operated eyes, 123 eyes or 83.67% exhibited a decrease in IOP. The mean preoperative IOP for the operative eye was 15.61±4.5mmHg; the mean post-operative IOP was 12.57±3.5mmHg; the mean IOP decrease after surgery was 3.16±4mmHg, for a mean decrease of 20%. This decrease is statistically significant, Pdecrease in IOP varies proportionally to the initial IOP. In glaucomatous patients, the mean preoperative IOP was 23.16±5.68mmHg and mean post-operative IOP was 14.5±2.7mmHg, a decrease of 37.39%. The decrease in IOP after cataract surgery was generally moderate. However, this IOP decreased proportionally to the initial IOP, thus giving significant decreases for higher IOPs. This decrease in IOP, well known after phacoemulsification, was also obtained after Manual Small Incision Cataract Surgery, a surgical technique which is increasingly employed in developing countries.

    The aim was to assess the impact of cataract surgeries in reducing visual disabilities and factors influencing it at three institutes of India. A retrospective chart review was performed in 2013. Data of 4 years were collected on gender, age, residence, presenting a vision in each eye, eye that underwent surgery, type of surgery and the amount the patient paid out of pocket for surgery. Visual impairment was categorized as; absolute blindness (no perception of light); blind (visual impairment (SVI) (visual impairment (6/18-6/60) and; normal vision (≥6/12). Statistically analysis was performed to evaluate the association between visual disabilities and demographics or other possible barriers. The trend of visual impairment over time was also evaluated. We compared the data of 2011 to data available about cataract cases from institutions between 2002 and 2009. There were 108,238 cataract cases (50.6% were female) that underwent cataract surgery at the three institutions. In 2011, 71,615 (66.2%) cases underwent surgery. There were 45,336 (41.9%) with presenting vision visual disability. The goal of improving vision related quality of life for cataract patients during the early stages of visual impairment that is common in industrialized countries seems to be non-attainable in the rural India.

    Full Text Available Ajay E Kuriyan, Harry W Flynn Jr, Sonia H YooDepartment of Ophthalmology, Bascom Palmer Eye Institute, University of Miami, Miami, FLAbstract: This case report describes the optical coherence tomography (OCT findings and clinical management of a patient with traumatic subluxed cataract. The patient presented with a traumatic subluxed cataract and vitreous prolapse into the anterior chamber. The anterior segment OCT showed vacuoles in the anterior subcapsular regions of the crystalline lens. The patient was treated with pars plana lensectomy, vitrectomy, and placement of an anterior chamber intraocular lens. The patient's best corrected visual acuity improved from hand motion at presentation to 20/25 during 3 years of follow-up. Anterior segment OCT demonstrates that the clinically visible vacuoles in traumatic cataract are located in the anterior subcapsular part of the lens. This is the first report in the literature using anterior segment OCT to visualize the subcapsular vacuolar changes in a traumatic cataract.Keywords: traumatic cataract, subluxed lens, vacuoles, anterior chamber intraocular lens, anterior segment optical coherence tomography

    Full Text Available La miastenia gravis juvenil (MGJ es un trastorno crónico auto inmune en el cual existen anticuerpos séricos que al unirse a los receptores de acetilcolin nicotínicos de la membrana muscular de la placa motora alteran la transmisión neuromuscular. El resultado es fatiga muscular precoz con progresión a la parálisis durante estados de contracción muscular iterativos (movimientos o sostenidos (posturas y más raramente parálisis permanente durante el reposo. Los músculos inervados por los nervios craneales, especialmente los extraoculares y elevadores de los párpados, tienen más tendencia a la debilidad muscular persistente que los inervados por otros pares craneales y las extremidades. Las formas clínicas de presentación son generalizadas, oculares y respiratorias. El diagnóstico se sospecha mediante la anamnesia, la fatiga anormal se comprueba mediante el examen físico y la estimulación eléctrica iterativa del nervio que inerva al músculo afectado pero no paralizado. Se corrobora mediante la administración de inhibidores de la acetilcolin esterasa (IACE que al aumentar la cantidad de acetilcolin en la hendidura sináptica, corrigen la fatiga o la debilidad muscular transitoriamente. Se hace el diagnóstico de certeza mediante la demostración sérica de anticuerpos contra los receptores de acetilcolin (ACRA. El tratamiento es a largo plazo sintomático con IACE y etiopatogénico con inmunosupresores, plasmaféresis, gamma globulina endovenosa y timectomía. El curso es crónico.

    Full Text Available Simultaneous bilateral primary pneumothorax is a very rare (1.6 / 100,000 and life-threatening condition. Clinical presentation may vary from mild dyspnea to tension pneumothorax. It may be milder particularly in younger patients, but more severe in patients with advanced age, and tube thoracostomy is a life preserver in the latter group. Since mortality and recurrence rates following tube thoracostomy are high, endoscopic approaches to bilateral hemithorax have been reported in literature. Apical wedge resection and pleural procedures are recommended in video thoracoscopy or mini thoracotomy even if no bulla and/or bleb are detected. Bilateral surgical interventions and additional pleural procedures are associated with increased rate of post-operative complications and longer postoperative hospital-stays. As a first-line approach, the surgical method toward any side of lung with air leakage following a previous tube thoracostomy is considered less invasive, especially in younger patients. Here, we present a case of simultaneous bilateral primary spontaneous pneumothorax (SBPSP in a 21-year old male with no history of smoking and chronic pulmonary disease. A unilateral surgical intervention was performed, and no recurrence was observed during 5-year follow up.

    Specimens of the anterior lens capsule with an attached monolayer of lens epithelial cells (LECs) were obtained from patients (=52) undergoing cataract surgery. Specimens were divided into three groups based on the type of cataract: nuclear cataract, cortical cataract and posterior subcapsular cataract (PSC). Clear lenses (=11) obtained from donor eyes were used as controls. Expression was studied by immunofluorescence, real-time PCR and Western blot. Statistical analysis was done using the student’s -test. Immunofluorescence results showed punctate localization of Cx43 at the cell boundaries in controls, nuclear cataract and PSC groups. In the cortical cataract group, cytoplasmic pools of Cx43 without any localization at the cell boundaries were observed. Real-time PCR results showed significant up-regulation of Cx43 in nuclear and cortical cataract groups. Western blot results revealed significant increase in protein levels of Cx43 and significant decrease of ZO-1 in all three cataract groups. Protein levels of alpha-catenin were decreased significantly in nuclear and cortical cataract group. There was no significant change in expression of beta-catenin in the cataractous groups. Our findings suggest that ZO-1 and alpha-catenin are important for gap junctions containing Cx43 in the LECs. Alterations in cell junction proteins may play a role during formation of different types of cataract.

    Histone acetylation plays key roles in gene expression, but its effects on superoxide dismutase 1 (SOD1) expression in senile cataract remains unknown. To address this problem, the study was to investigate the influence of histone acetylation on SOD1 expression and its effects in the pathogenesis of senile cataract. Senile cataract was classified into three types—nuclear cataract (NC), cortical cataract (CC), and posterior subcapsular cataract (SC)—using the Lens Opacities Classification System III. In senile cataracts, SOD1 expression decreased significantly. Both H3 and H4 were deacetylated at −600 bp of the SOD1 promoter of cataract lenses, and hypoacetylated at −1500, −1200, and −900 bp. In hypoacetylated histones, the hypoacetylation pattern differed among the cataracts. In vitro, anacardic acid (AA) significantly reduced H3 and H4 acetylation at the SOD1 promoter, decreased protein expression, and induced cataract formation in rabbits. AA also inhibited HLEC viability and increased cell apoptosis. In contrast, trichostatin A (TSA) was able to efficaciously stop AA’s effects on both rabbit lenses and HLECs. Decreased histone acetylation at the SOD1 promoter is associated with declined SOD1 expression in senile cataracts. Histone acetylation plays an essential role in the regulation of SOD1 expression and in the pathogenesis of senile cataracts. PMID:27703255

    To determine the risk factors for the development of cataract in children with uveitis of any etiology. Cohort study. Two hundred forty-seven eyes of 140 children with uveitis were evaluated for the development of vision-affecting cataract. Demographic, clinical, and treatment data were collected between the time of presentation and the first instance cataract was recorded or findings at final follow-up. Main outcome measures included the prevalence of cataract and distribution by type of uveitis, incidence of new onset cataract time to cataract development, and risk factors for the development of cataract. The prevalence of cataract in our cohort was 44.2% and was highest among eyes with panuveitis (77.1%), chronic anterior uveitis (48.3%), and intermediate uveitis (48.0%). The overall incidence of newly diagnosed cataract was 0.09 per eye-year, with an estimated 69% to develop uveitis-related cataract with time. The main factors related with cataract development were the number of uveitis flares per year (hazard ratio [HR] = 3.06 [95% confidence interval {CI}, 2.15-4.35], P uveitis and is most strongly related to the extent of inflammation recurrences and ocular complications. We suggest that controlling the inflammation, even using higher doses of systemic and topical corticosteroids, is of importance in preventing ocular complications, such as cataract.

    2014-01-01

    Full Text Available Osteomyelitis of the pubis symphysis is a rare condition. There have been various reports in the literature of inflammation and osteomyelitis as well as septic arthritis of pubic symphysis. However, due to the fact that these conditions are rare and that the usual presenting symptoms are very nonspecific, osteomyelitis of the pubic symphysis is often misdiagnosed, thus delaying definitive treatment. We present a case that to our knowledge is the first case in literature of osteomyelitis of the pubic symphysis in a 17-year-old boy with juvenile idiopathic arthritis (JIA, which was initially misdiagnosed and progressed to bilateral adductor abscesses. A high suspicion of such condition should be considered in a JIA patient who presents with symphysis or thigh pain.

Haydarpasa Numune Education and Research Hospital, Ophthalmology Clinic, Istanbul, Turkey. Clinical trial. Eyes with hard nuclear cataract that had previous PKP were randomly assigned to have phacoemulsification or ECCE. Noncontact specular microscopy was performed preoperatively and 1, 3, and 6 months postoperatively. Twenty-six eyes of 26 patients were enrolled (14 phacoemulsification; 12 ECCE). Six months postoperatively, the mean corneal ECD was statistically significantly lower in the phacoemulsification group (1869.50 cells/mm(2) ± 158.05 [SD]) than in the ECCE group (1996.00 ± 127.96 cells/mm(2)) (P=.024). The mean percentage of endothelial cell loss at 6 months was 20.3% and 12.7%, respectively (P.05). Extracapsular cataract extraction seemed to cause less endothelial cell damage than phacoemulsification in post-PKP patients with hard nuclear cataract. Copyright © 2011 ASCRS and ESCRS.

  12. [Incisions for biaxial and coaxial microincision cataract surgery].

    2010-02-01

    Microincision cataract surgery (MICS) represents a new level in the development of cataract surgery. Phacoemulsification with intraocular lens (IOL) implantation via incisions of phaco tip (C-MICS), or by the biaxial approach, with separation of the phaco tip and irrigation (B-MICS). Compared with standard small-incision cataract surgery, the advantages of MICS are less corneal astigmatism and fewer corneal surface irregularities, with favorable implications for visual quality and early rehabilitation. In the effort toward smaller incisions, special interest should be given to wound integrity, especially regarding the risk of endophthalmitis. With limited corneal elastic capacity, irreversible expansion of the incision with tissue laceration may occur. Smaller incisions are superior only if they cause less trauma. This requires an optimized relationship between incision size and manipulation during IOL implantation as well as attention to safety issues. MICS offers a platform for new benchmarks in phacoemulsification.

  13. Cataract related blindness in India & its social implications.

    The prevalence of blindness in India is 14.9 per 1000. Eighty per cent of this blindness is due to cataract alone. Most of the cataract blinds in the country are in the rural areas while the surgical service delivery network is concentrated in the urban areas. Thus a large proportion of patients in the rural areas continue to remain blind. This situation has many social implications. There is loss of productivity, breakdown of interpersonal relationships, depressive manifestations, loss of self esteem and most patients lead an isolated humiliating life. Patients lack information on the available services and continue to remain blind for years even after being diagnosed as operable. This is unfortunate because cataract surgery is one of the most cost effective health interventions known and most operated patients, irrespective of the surgical technique, are immensely satisfied with the level of visual rehabilitation after surgery.

    To determine the incidence of and associated risk factors for uveitis after cataract surgery. A total of 17,757 eyes were identified and records of 42 eyes that developed uveitis and 2320 eyes that did not were reviewed. Postsurgical uveitis was defined as persistent inflammation for ≥ 6 months after surgery. Forty-two eyes of 35 patients developed uveitis (0.24%). Eleven patients underwent consecutive cataract surgery but developed unilateral uveitis, and intraoperative complications occurred in 55% of uveitic eyes compared to 0% in fellow eyes (p < 0.05). Median duration of inflammation was 8 and 11.5 months in eyes with and without vitrectomy (p < 0.05). Intraocular complications occurred in 44 and 8.3% of eyes that did and did not develop uveitis, respectively (p = 0.01). Postsurgical uveitis developed after approximately 1 in 400 cataract surgeries and occurred more frequently in eyes experiencing intraoperative complications.

    1994-01-01

    An 82-year-old man had pain and decreased vision in his right eye 15 months after uncomplicated cataract surgery. Examination revealed a large corneoscleral abscess with a 2 mm x 1 mm area of fluorescein staining at the base of a broken protruding 10-0 nylon suture. Streptococcus pneumoniae was isolated from both the suture and base of the ulcer. Despite intensive topical, subconjunctival, and systemic antibiotics, a large corneal perforation developed, necessitating a 10 mm tectonic penetrating keratoplasty. Long-term follow-up of patients after cataract surgery is important and should include an inspection of the limbal wound and removal of loose or broken exposed sutures. Suture-related complications will be eliminated if clinical studies prove the safety and efficacy of sutureless cataract surgery.

    Full Text Available A cataract is considered a disease of great magnitude and importance due to the decrease of visual acuity it causes and because it is widespread in the world. A descriptive study was conducted in order to describe the results of cataract surgery by extracting the extracapsular lens and placing an intraocular lens in elderly people operated on at the "Camilo Cienfuegos" General Hospital in the province of Sancti Spiritus, belonging to Jatibonico municipality in the period from January 3 to December 31, 2008. The population consisted of all cataract surgery patients aged 60 and over. 187 patients. The following variables were used: sex, age, eye diseases associated complications and visual results after placing an intraocular lens. Age between 60 and 69 years (78%, and female sex (29% were predominant. Posterior capsule rupture (34% and its opacity (34% were the main intraoperative and postoperative complications. Despite complications, there was an improvement of visual acuity evident after the completion of surgery.

    Full Text Available This study was done to compare the results of posterior continuous curvilinear capsulorhexis created using forceps with those created using vitrector in eyes suffering from congenital cataract. Vitrectorhexis term was first used by Wilson et al in 1999. [1] Fifty eyes with congenital and developmental cataract were included in this study. The posterior capsulorhexis was created using utrata forceps in 17 eyes or through a vitrector in 33 eyes. Forceps capsulorhexis was performed before IOL implantation, while vitrectorhexis was performed after IOL implantation in the bag. The results of both the surgery were compared using the following criteria: incidence of extension of rhexis, ability to achieve posterior rhexis of appropriate size, ability to implant the IOL in the bag, the surgical time, and learning curve. Vitrectorhexis after IOL implantation was an easy to learn alternative to manual posterior continuous curvilinear capsulorhexis in pediatric cataract surgery. It was more predictable and reproducible, with a short learning curve and lesser surgical time.

    Aggressive juvenile fibromatosis of the jawbones is a rare tumor presenting as infiltrative mass with unpredictable evolution. We report herein a 17-year-old student with a 6-month history of radiologically proven resorption of a part of the mandible, lingual displacement of tooth 34 and malocclusion. Alveolar ridge resorption and three dark-brown foci in the bone were seen after the tooth was extracted. Histological study showed the tumor tissue to have a bundle-like structure; immunohistochemically it was positive for vimentin, smooth muscle actin, beta-catenin, Ki-67 (5%), and negative for desmin and cytokeratin 34bE12. The golden standard in the diagnostics of desmoid fibromatoses is the nuclear or membrane expression of beta-catenin, which is found in 90% of the cases. Differential diagnosis include mandibular fibroma, well-differentiated fibrosarcoma, fibrosing histiocytoma, and infiltration from adjacent soft-tissue tumor. Aggressive juvenile fibromatosis should be managed by radical excision. Local recurrences are not rare, but metastases do not develop. In rare cases this type of fibromatosis has been known to regress spontaneously. Aggressive fibromatosis is a diagnostic challenge, since it remains in the grey zone between benign and malignant lesions of the oral cavity.

    We report on three siblings with a novel mental retardation (MR) syndrome who were born to distantly related Iranian parents. The clinical problems comprised severe MR, cataracts with onset in late adolescence, kyphosis, contractures of large joints, bulbous nose with broad nasal bridge, and thick lips. Two patients also had uni- or bilateral iris coloboma. Linkage analysis revealed a single 10.4 Mb interval of homozygosity with significant LOD score in the pericentromeric region of chromosome 4 flanked by SNPs rs728293 (4p12) and rs1105434 (4q12). This interval contains more than 40 genes, none of which has been implicated in MR so far. The identification of the causative gene defect for this syndrome will provide new insights into the development of the brain and the eye.

With a view to exploring the clinical usefulness of these findings, this study examined its preventive effect when administered topically as an eye drop.Methods: Diabetes was induced by intraperitoneal injections of streptozotocin. At the onset of diabetes, an eye drop preparation containing 2.5% sodium pyruvate was administered six times a day at 90-minute intervals. Treatment was continued for 6 weeks. Cataract formation was monitored ophthalmoscopically after mydriasis with 1% tropicamide eye drops. Subsequently, the treated and untreated diabetic animals and the age-matched normal controls were euthanized, their eyes enucleated, and the lenses isolated for biochemical assessment of protein glycation and glutathione levels.Results: Treatment with pyruvate eye drops was found to be significantly effective in inhibiting protein glycation. Glutathione levels were also better maintained. In addition, ophthalmoscopic examination revealed that the incidence of cataract in the pyruvate-treated group was only 12% as compared with the untreated diabetics in whom the incidence was 73%. Cataracts at this stage were largely equatorial.Conclusion: The results demonstrate that topical application of pyruvate can potentially be useful in attenuating or preventing cataract formation induced by diabetes and other conditions of oxidative stress.Keywords: pyruvate eye drops, diabetic cataract, protein glycation, oxidative stress

    Full Text Available Background: Cases of cataract surgery without penetrating keratoplasty in patients with Peters' anomaly are very rare. We report a case of Peters' anomaly type 2 with tilted lens due to synechia between the lens and iris that was treated with cataract surgery without penetrating keratoplasty. Case Presentation: A 16-year-old girl had Peters' anomaly in both eyes. Corneal opacity was severe in the left eye due to high-grade dysgenesis of the anterior segment. In the right eye, corneal opacity had spread from the center of the cornea to the inferotemporal side, and there was synechia between the iris and corneal endothelium from the inferonasal side to the inferotemporal side. Opacity was observed in the anterior pole of the lens, and there was synechia between the anterior iris and the lens. Ultrasound biomicroscopy (UBM revealed that the lens was tilted because of synechia. The tilted lens induced astigmatism, which reduced visual acuity to 20/250, in conjunction with a cataract. Cataract surgery was performed; the synechia between the lens capsule and the iris was severed, an intraocular lens was inserted, and the tilt was repaired. UBM was used postoperatively to confirm that the lens capsule synechia had been corrected and that the intraocular lens was not tilted. As a result, visual acuity improved to 20/100; glaucoma and expansion of corneal opacity were not observed. Conclusions: Severing of the synechia between the cataract and iris, during cataract surgery, in a patient with Peters' anomaly type 2 resulted in favorable postoperative visual acuity.

    Full Text Available Zoltan Z NagyDepartment of Ophthalmology, Semmelweis University, Budapest, HungaryAbstract: Femtosecond lasers represent a new frontier in cataract surgery. Since their ­introduction and first human treatment in 2008, a lot of new developments have been achieved. In this review article, the physical principle of femtolasers is discussed, together with the indications and side effects of the method in cataract surgery. The most important clinical results are also presented regarding capsulotomy, fragmentation of the crystalline lens, corneal wound creation, and refractive results. Safety issues such as endothelial and macular changes are also discussed. The most important advantage of femtolaser cataract technology at present is that all the important surgical steps of cataract surgery can be planned and customized, delivering unparalleled accuracy, repeatability, and consistency in surgical results. The advantages of premium lenses can be maximally used in visual and presbyopia restoration as well. The advantages of ­premium lenses can be maximally used, not only in visual, but in presbyopia restoration as well. Quality of vision can be improved with less posterior chamber lens (PCL tilt, more centralized position of the PCL, possibly less endothelial damage, less macular edema, and less posterior capsule opacification (PCO formation. This technological achievement should be followed by other technical developments in the lens industry. Hopefully this review article will help us to understand the technology and the results to ­demonstrate the differences between the use of femtolasers and phacoemulsification-based cataract surgery. The most important data of the literature are summarized to show ophthalmologists the benefits of the technology in order to provide the best refractive results to the patient.Keywords: femtosecond laser-assisted cataract surgery, capsulotomy, lens fragmentation, corneal wound, arcuate keratotomy, safety

    Pathophysiological mechanisms of cataract formation include deficient glutathione levels contributing to a faulty antioxidant defense system within the lens of the eye. Nutrients to increase glutathione levels and activity include lipoic acid, vitamins E and C, and selenium. Cataract patients also tend to be deficient in vitamin A and the carotenes, lutein and zeaxanthin. The B vitamin riboflavin appears to play an essential role as a precursor to flavin adenine dinucleotide (FAD), a co-factor for glutathione reductase activity. Other nutrients and botanicals, which may benefit cataract patients or help prevent cataracts, include pantethine, folic acid, melatonin, and bilberry. Diabetic cataracts are caused by an elevation of polyols within the lens of the eye catalyzed by the enzyme aldose reductase. Flavonoids, particularly quercetin and its derivatives, are potent inhibitors of aldose reductase. Glaucoma is characterized by increased intraocular pressure (IOP) in some but not all cases. Some patients with glaucoma have normal IOP but poor circulation, resulting in damage to the optic nerve. Faulty glycosaminoglycan (GAG) synthesis or breakdown in the trabecular meshwork associated with aqueous outflow has also been implicated. Similar to patients with cataracts, those with glaucoma typically have compromised antioxidant defense systems as well. Nutrients that can impact GAGs such as vitamin C and glucosamine sulfate may hold promise for glaucoma treatment. Vitamin C in high doses has been found to lower IOP via its osmotic effect. Other nutrients holding some potential benefit for glaucoma include lipoic acid, vitamin B12, magnesium, and melatonin. Botanicals may offer some therapeutic potential. Ginkgo biloba increases circulation to the optic nerve; forskolin (an extract from Coleus forskohlii) has been used successfully as a topical agent to lower IOP; and intramuscular injections of Salvia miltiorrhiza have shown benefit in improving visual acuity and

  5. Low-Dose Radiation Cataract and Genetic Determinants of Radiosensitivity

    The lens of the eye is one of the most radiosensitive tissues in the body. Ocular ionizing radiation exposure results in characteristic, dose related, progressive lens changes leading to cataract formation. While initial, early stages of lens opacification may not cause visual disability, the severity of such changes progressively increases with dose until vision is impaired and cataract extraction surgery may be required. Because of the transparency of the eye, radiation induced lens changes can easily be followed non-invasively over time. Thus, the lens provides a unique model system in which to study the effects of low dose ionizing radiation exposure in a complex, highly organized tissue. Despite this observation, considerable uncertainties remain surrounding the relationship between dose and risk of developing radiation cataract. For example, a growing number of human epidemiological findings suggest significant risk among various groups of occupationally and accidentally exposed individuals and confidence intervals that include zero dose. Nevertheless, questions remain concerning the relationship between lens opacities, visual disability, clinical cataract, threshold dose and/or the role of genetics in determining radiosensitivity. Experimentally, the response of the rodent eye to radiation is quite similar to that in humans and thus animal studies are well suited to examine the relationship between radiation exposure, genetic determinants of radiosensitivity and cataractogenesis. The current work has expanded our knowledge of the low-dose effects of X-irradiation or high-LET heavy ion exposure on timing and progression of radiation cataract and has provided new information on the genetic, molecular, biochemical and cell biological features which contribute to this pathology. Furthermore, findings have indicated that single and/or multiple haploinsufficiency for various genes involved in DNA repair and cell cycle checkpoint control, such as Atm, Brca1 or Rad9

    Diplopia is an infrequent but distressing adverse outcome after uncomplicated cataract surgery. Many factors may contribute to the occurrence of this problem, including prolonged sensory deprivation resulting in disruption of sensory fusion, paresis of one or more extraocular muscles, myotoxic effects of local anaesthesia, optical aberrations (for example, aniseikonia) and pre-existing disorders (for example, thyroid orbitopathy). The purpose of this review is to present the aetiology and clinical features of diplopia after cataract surgery and to discuss the possible modalities for the prevention and treatment of this frustrating complication.

    The authors describe a technique to improve the control and safety of vertical chopping during hard cataract surgery. Whereas the conventional vertical chop technique uses a sharp vertical chopper, the proposed technique uses a short blunt chopper. This requires complete engagement of the central nucleus by a phaco tip. The authors first drilled a hole into the endonucleus. By rotating the Kelman phaco tip clockwise, the nucleus was deeply impaled horizontally and firmly engaged with the phaco tip. This was followed by vertical chopping. This technique results in safer and more effective vertical chopping in patients with hard cataracts. Copyright 2012, SLACK Incorporated.

    Diabetes mellitus succeeded by diabetic cataract was induced to experimental animals (Wistar rats) by applying an Alloxan injection. Eye properties deterioration were monitored from clinical standpoint and using Raman and infrared spectroscopies. All cases of developed cataract were followed by important changes in vibrational spectra, but Raman spectroscopy proved to be more useful because of larger number of resolved bands. Each kth Raman spectrum of diseased lens (in our notation k denotes disease age and cataract degree as described in chapter Alloxan diabetes) can be expressed as a sum of the Raman spectrum of healthy lens, I R, multiplied by a suitable constant ck, and the fluorescent background spectrum, I FB. We introduce the ratio of integrated intensities IFB and ck* IR as a physical parameter called fluorescent background index F FB. It turns out that FFB grows as cataract progresses and has its maximum at approx. 4, whence it decreases. FFB values are larger for 200-1800 cm -1 spectral interval than for 2500-4000 cm -1 interval. In the same manner another quantity called water band index FW is defined for each Raman spectrum of diseased lens in the 2800-3730 cm -1 interval. It is the ratio of the integrated intensity from 3100 to 3730 cm -1 (water band interval) divided by the integrated intensity of the 2800-3100 cm -1 interval (C-H stretching region). FW increases monotonously with cataract progression with maximum at the end of monitored period (5 months). These two indices helped us to formulate a model describing disease development from the earliest molecular changes to its macroscopic manifestation. As glucose and other small saccharide molecules enter the lens tissue, they bind to crystallin and other proteins via O- and S-glycosidic linkages which occur probably at tyrosine and cystein sites. In Raman spectrum this corresponds to broad bands at 540 and 1100 cm -1 which grow together with the fluorescent background, because both contributions

    When cataract surgery and glaucoma surgery are combined, the theoretical advantages of pressure control, removal of the visual impairment, and protection against an increase in intraocular pressure (IOP) in the immediate postoperative period are gained. The authors' objective was to determine whether ab interno laser thermal sclerostomy (LTS) combined with cataract surgery would be as effective as trabeculectomy combined with cataract surgery. Ab interno LTS was compared with trabeculectomy, retrospectively, for patients who had undergone combined cataract and glaucoma surgery. There was no significant difference in the numbers of patients using no medications or fewer medications at 6 and 12 months. There was a greater reduction in IOP in the LTS group. LTS may be better than trabeculectomy in combined cataract and glaucoma surgery because it reduces the IOP more. Compared with trabeculectomy, LTS is simpler to perform and adds less operating time to cataract surgery. Continued follow-up is recommended.

    As the second century of partnership begins, child psychiatry and juvenile justice face continuing challenges in meeting the mental health needs of delinquents. The modern juvenile justice system is marked by a significantly higher volume of cases, with increasingly complicated multiproblem youths and families with comorbid medical, psychiatric, substance abuse disorders, multiple family and psychosocial adversities, and shrinking community resources and alternatives to confinement. The family court is faced with shrinking financial resources to support court-ordered placement and treatment programs in efforts to treat and rehabilitate youths. The recognition of high rates of mental disorders for incarcerated youth has prompted several recommendations for improvement and calls for reform [56,57]. In their 2000 annual report, the Coalition for Juvenile Justice advocated increased access to mental health services that provide a continuum of care tailored to the specific problems of incarcerated youth [58]. The specific recommendations of the report for mental health providers include the need for wraparound services, improved planning and coordination between agencies, and further research. The Department of Justice, Office of Juvenile Justice and Delinquency Prevention has set three priorities in dealing with the mental health needs of delinquents: further research on the prevalence of mental illness among juvenile offenders, development of mental health screening assessment protocols, and improved mental health services [59]. Other programs have called for earlier detection and diversion of troubled youth from juvenile justice to mental health systems [31,56]. Most recently, many juvenile and family courts have developed innovative programs to address specific problems such as truancy or substance use and diversionary or alternative sentencing programs to deal with first-time or nonviolent delinquents.

    Full Text Available OBJECTIVE: To evaluate the efficacy and safety of bilateral pallidotomies in five patients with generalized dystonia. BACKGROUND: Generalized dystonias are frequently a therapeutic challenge, with poor responses to pharmacological treatment. GPi (globus pallidus internus pallidotomies for Parkinson's disease ameliorate all kinds of dyskinesias/dystonia, and recent studies reported a marked improvement of refractory dystonias with this procedure. METHODS: Five patients with generalized dystonias refractory to medical treatment were selected; one posttraumatic and four idiopathic. The decision to perform bilateral procedures was based on the predominant axial involvement in these patients. Dystonia severity was assessed with the Burke-Fahn-Marsden Dystonia Scale (BFM. Simultaneous procedures were performed in all but one patient, who had a staged procedure. They were reevaluated with the same scale (BFM by an unblinded rater at 1, 2, 3, 30, 60, 90, 120 and 180 days post-operatively. RESULTS: The four patients with idiopathic dystonia showed a progressive improvement up to three months; the patient with posttraumatic dystonia relapsed at three months. One patient had a marked improvement, being able to discontinue all the medications. A mean decrease in the BFM scores of 52,58% was noted. One patient had a trans-operative motor seizure followed by a transient hemiparesis secondary to rack hemorrhage; other was lethargic up to three days after the procedure. CONCLUSIONS: Our results show that bilateral GPi pallidotomies may be a safe and effective approach to medically refractory generalized dystonias; it can also be speculated that the posttraumatic subgroup may not benefit with this procedure.As distonias generalizadas são freqüentemente um desafio terapêutico, com pobres respostas aos tratamentos farmacológicos.

    Full Text Available Lhermitte-Duclos disease (LDD is a pathologic entity with progrediating, diffuse hypertrophy chiefly of the stratum granulosum of the cerebellum. Typically LDD is a unilateral lesion of the cerebellum or in vermis. Here we report a case of LDD with bilateral lesions of cerebellar hemispheres managed surgically. A 28-year-old woman presented with one-year history of progressive headache, nausea, vomiting, and blurred vision. Neurologic examination revealed a bilateral mild papilledema, mild dysmetria, and dysdiadochokinesia. The cerebellar lesions caused moderate mass effect in posterior fossa with hydrocephalus, and Chiari type I malformation. We performed the suboccipital-retrosigmoid approach, and removed completely the left intracerebellar mass. Symptoms related to elevated intracranial pressure disappeared in a short period postoperatively.

    Full Text Available The need for punishment of juveniles occurred from the time when there was no clear line separating them from the adult criminal population. At the same time, the evolution of the juvenile punishment is not in itself involve substantial changes to their criminal status. On the contrary, the status of minors in society did not show serious differences regarding the status of young adults, as well as the adult elderly. On the other hand, on the ground of their punishment is recorded deviations that go in the direction of application of mild corporal punishment. Closing the minor was performed in a physically separate parts of the general penal institutions with the use of a lower degree of restrictions while serving juvenile prison. Due to the different treatment of minors during the evolution of their criminal status leads to their different treatment in comparative law. That is why we are witnessing the existence of numerous differences in the juvenile punishment in some countries in the world. On the European continent there is a wide range of different legal solutions when it comes to punishing juveniles. There are considerable differences in the procedure pronouncing juvenile prison and in particular penal treatment of juveniles in penitentiary institutions. For these reasons, the author has decided to show the basic statutory provisions in the part that relates to the issue of punishment of minors in the legislation of individual countries.

    Juvenile myasthenia gravis is a relatively rare autoimmune neuromuscular disorder. The pathophysiology of juvenile myasthenia gravis is similar to that of adult myasthenia gravis, though there remain important differences regarding presentation and therapeutic options. We review the pathophysiology, clinical presentation, and treatment options for juvenile myasthenia gravis. Randomized clinical studies of myasthenia gravis have been carried out primarily in adult populations. As juvenile myasthenia gravis is rare, it has been difficult to collect prospective randomized controlled data to evaluate treatment outcomes and efficacy. A recent retrospective series suggests that, as in adult myasthenia gravis, thymectomy is a viable therapeutic option for selected cases of generalized juvenile myasthenia gravis. This is corroborated by the clinical experience of the authors in a referral center with a cohort of patients affected by juvenile myasthenia gravis over a number of years. Recent studies illustrate that some, but not all, adult research on myasthenia gravis is applicable to children and adolescents with juvenile myasthenia gravis. Adult research can inform pediatric studies, but should not be regarded as a substitute for dedicated research in those populations.

    To determine the value of serial personal photographs in timing the onset of unilateral cataracts in children over 6 months of age. Personal photographs from children with unilateral cataracts who underwent cataract extraction and intraocular lens implantation when > or =6 months of age were reviewed. Photographs were evaluated for changes in the red reflex, which might indicate the presence of a cataract. Twelve children underwent cataract surgery at a mean age of 37 months. They were followed for a mean of 32 months. Ten children were diagnosed as having an acquired cataract by photographic review documenting a previously normal red reflex. The visual acuity in the affected eye of 4 of these children improved to > or =20/60. Cataracts were visible on photographs prior to clinical diagnosis in 6 patients, from 0.5 to 22 months prior to clinical diagnosis. Visual outcomes did not relate closely to the photographically documented duration of the cataract prior to treatment. Photographs were not helpful in timing the onset of cataract in 2 children due to the poor quality of the images. Serial personal photographs are sometimes helpful in determining whether cataracts are acquired. However, the usefulness of personal photographs alone in predicting the visual outcome after cataract surgery was limited in this small, retrospective study.

    Management of the patient with coexisting cataract and AMD presents unique challenges to the cataract surgeon, the retina specialist, and the patient. A common clinical scenario is the patient in whom both the cataract and macular pathology appear to be contributing to decreased visual acuity. As with any surgery, the expectations from cataract removal must be evaluated thoroughly and understood clearly by both the patient and the cataract surgeon. Most patients with AMD who undergo cataract surgery feel that the surgery is worthwhile, and they report improvement of visual function and quality of life. In patients with mild AMD, improvement in central visual acuity and attainment of driving vision are realistic and achievable goals. In an eye with central disciform scarring or geographic atrophy there may be potential for improvement in color discrimination, contrast, or clarity of peripheral vision. In cases of dense cataract obscuring macular detail, cataract removal may be necessary to allow for adequate biomicroscopy and angiography, especially in an eye that may be at high risk for the development of choroidal neovascularization. It is often challenging to estimate the relative impact on visual impairment made by the lens opacities and the macular changes and the benefits and risks of cataract surgery in eyes with AMD should be carefully evaluated. Is cataract surgery justified in these patients? Does cataract surgery aggravate AMD in some patients?

    Full Text Available Cataract is a leading cause of curable blindness. Hence, in its global declaration of ‘Vision 2020 Right to Sight’, the World Health Organization (WHO encouraged its member countries to address the problem of incident cataract. Many factors are related to the cataract surgical coverage rate, such as gender and diabetes mellitus. The objective of this study was to determine the cataract surgical coverage rate and investigate the determinants factors of cataract surgical coverage rate among adults 40 years old and above with cataract. A cross sectional study was conducted using National Basic Health Research (Riskesdas 2007 data. Cataract surgery was defined as surgery conducted within the last 12 months before the survey was performed. There were 6939 subjects (3105 male, 3834 female who fulfilled the study criteria. The cataract surgical coverage rate was 19.3%. The cataract surgical coverage rate was lower in subjects with low education, in the group of farmers/fishermen/laborers, in the 40-49 years age group, in rural areas, and in subjects of low socioeconomic status (p0.05. Determinants that were related to cataract surgical coverage rate were age, type of area of residence, socioeconomic status, and region of residence (p<0.001. The implementation of educational programs and reforms to local ophthalmic health services may improve the cataract surgical coverage rate.

  3. Compensation following bilateral vestibular damage

    Full Text Available Bilateral loss of vestibular inputs affects far fewer patients than unilateral inner ear damage, and thus has been understudied. In both animal subjects and human patients, bilateral vestibular hypofunction (BVH produces a variety of clinical problems, including impaired balance control, inability to maintain stable blood pressure during postural changes, difficulty in visual targeting of images, and disturbances in spatial memory and navigational performance. Experiments in animals have shown that nonlabyrinthine inputs to the vestibular nuclei are rapidly amplified following the onset of BVH, which may explain the recovery of postural stability and orthostatic tolerance that occurs within 10 days. However, the loss of the vestibulo-ocular reflex and degraded spatial cognition appear to be permanent in animals with BVH. Current concepts of the compensatory mechanisms in humans with BVH are largely inferential, as there is a lack of data from patients early in the disease process. Translation of animal studies of compensation for BVH into therapeutic strategies and subsequent application in the clinic is the most likely route to improve treatment. In addition to physical therapy, two types of prosthetic devices have been proposed to treat individuals with bilateral loss of vestibular inputs: those that provide tactile stimulation to indicate body position in space, and those that deliver electrical stimuli to branches of the vestibular nerve in accordance with head movements. The relative efficacy of these two treatment paradigms, and whether they can be combined to facilitate recovery, is yet to be ascertained.

    Bilateral patellae fractures represent a rare entity, accounting for approximately 2.9% of all lesions interesting in this anatomical district. In most cases found in the published work, they are described as stress fractures or as complications of chronic diseases such as osteoporosis, renal failure and secondary hyperparathyroidism. Although many pathogenetic mechanisms have been supposed, none have been proved for certain. Insufficiency fractures of the patellae are rare events and no data has been published on their incidence. We present a case of bilateral fracture of the patellae due to an indirect trauma occurring in an 85-year-old patient affected by Parkinson's disease, osteoporosis and diffuse degenerative osteoarthritis. X-ray of the knees (anteroposterior and lateral) and magnetic resonance imaging evaluation confirmed the fractures. The patient was treated conservatively. She had a good result, returning to her previous autonomous ambulation. This case is unusual because there was no direct trauma to the knees because of bilaterality, but confirmed previous observations about insufficiency fractures of patellae in the presence of comorbidity. Insufficiency fractures of patellae can be an insidious condition in elderly people. Prepatellar pain, a common symptom in the relapse phase of degenerative arthritis of the knee, should not be underestimated, particularly in patients with diseases influencing metabolism of bone and with an elevated risk of fall. A periodical clinical and instrumental follow up should be done in these patient. Moreover, we underline the necessity of a multidisciplinary approach.

    As the world's population ages, cataract-induced visual dysfunction and blindness is on the increase. This is a significant global problem. The most common symptoms of cataracts are glared and blurred vision. Usually, people with cataract have trouble seeing and reading at distance or in low light and also their color perception is altered. Furthermore, cataract is a sneaky disease as it is usually a very slow but progressive process, which creates adaptation so that patients find it difficult to recognize. All this can be very difficult to explain, so we built and tested an optical device to help doctors giving comprehensive answers to the patients' symptoms. This device allows visualizing how cataract impairs vision mimicking the optical degradation of the crystalline related cataracts. This can be a valuable optical tool for medical education as well as to provide a method to illustrate the patients how cataract progression process will affect their vision.

    Childhood cataracts have become a leading cause of preventable childhood blindness in many areas of the world. Here we summarize regional focus group discussions from the 4th Annual International Congenital Cataract Symposium on the current situation, challenges, and recommendations for the management of congenital cataracts in sub-Saharan Africa, the Middle East and North Africa, South Asia, Central America, South America, and developed nations. Strategies for managing congenital cataracts must be adapted and developed according to regional conditions. A basic framework for acceptable outcomes must focus on developing systems to address the critical components of education, access, quality care, and good follow-up.

    Full Text Available Pediatric cataract is a leading cause of childhood blindness. This study aimed to determine the genetic cause of pediatric cataract in Australian families by screening known disease-associated genes using massively parallel sequencing technology. We sequenced 51 previously reported pediatric cataract genes in 33 affected individuals with a family history (cases with previously known or published mutations were excluded using the Ion Torrent Personal Genome Machine. Variants were prioritized for validation if they were predicted to alter the protein sequence and were absent or rare with minor allele frequency 60% of familial pediatric cataract in Australia, indicating that still more causative genes remain to be identified.

    Full Text Available A 13-year-old male patient with a recent history of hyperglycemia developed an acute bilateral posterior subcapsular cataract, consisting of fine feathery streak-like opacities. On examination, his uncorrected visual acuity was 20/50 and J4 at near in both eyes. Under cycloplegia, a moderate hypermetropic refraction was noted in both eyes. He was diagnosed with acute posterior subcapsular cataract secondary to diabetes mellitus. Two weeks after resolution of the hyperglycemic state, the bilateral feathery streak-like posterior subcapsular opacities regressed completely, hypermetropic refraction decreased and uncorrected visual acuity improved to 20/20 and J1 in both eyes.Paciente de 13 anos, com história recente de hiperglicemia, desenvolveu subitamente, catarata subcapsular posterior em ambos os olhos, consistindo de finas opacidades dispostas em forma de pena. A acuidade visual não corrigida era de 20/50 e de J4 para perto, em ambos os olhos. Sob cicloplegia, verificou-se em ambos os olhos uma moderada refração hipermetrópica. Foi, então, diagnosticado caso agudo de catarata subcapsular posterior secundária ao diabetes mellitus. Observou-se resolução total da opacidade subcapsular posterior em ambos os olhos duas semanas após regressão do quadro hiperglicêmico, assim como redução da refração hipermetrópica com melhoria da acuidade visual.

    1995-05-01

    The nomenclature and classification criteria for arthritis in children should be dealt with initially as separate issues, although they are undoubtedly intertwined. The classification criteria should aim to delineate homogeneous patient populations, yet should be flexible enough to incorporate advances in disease knowledge. It should be recognized that arriving at an international consensus for classification criteria will merely provide a set of operational definitions to facilitate research, and not a set of diagnostic criteria. Indeed the only point to obtaining consensus is to begin a process of systematic ongoing review of the criteria. The labels attached to any of these diseases should facilitate accurate communication. In view of the heterogeneous nature of childhood arthritis, consideration should be given to using a broad umbrella term such as juvenile or childhood arthritis only for communicating with the lay public. Medical nomenclature should be formulated to reflect accurately homogeneous subgroups of arthritis, and should not artificially proscribe a relationship between paediatric and adult disease.

    The new classification of juvenile idiopathic arthritis (JIA) is described in this review. Clinical characteristics divide JIA in to subtypes: systemic, oligoarticular (persistent and extended type), RF-positive and--negative polyarticular, enthesitis-related arthritis and psoriatic arthritis. In addition to the clinical characteristics, genetic and biochemical differences suggest that JIA could be regarded as a general term covering various diseases. Complications described are uveitis, temporomandibular joint affection and growth disturbances. The therapeutic strategy should be planned individually according to age, subtype and disease activity and carried out as teamwork with several specialties. Drugs showing significant effectiveness in controlled studies are primarily methotrexate and sulphasalazine. An immunomodulating agent, etanercept, a soluble TNF alpha-receptor fusion protein, has shown a promising effect in severe polyarticular JIA refractory to methotrexate treatment.

    Full Text Available Juvenile hyaline fibromatosis is a rare, autosomal-recessive disease characterized by papular and nodular skin lesions, gingival hyperplasia, joint contractures and bone involvement in variable degrees. It is a connective tissue disorder with aberrant synthesis of glycosaminoglycans by fibroblasts. We report a 5-year-old female born of first-degree consanguineous marriage who presented with multiple, recurrent, painless, variable-sized nodules. Fine needle aspiration cytology smears and the subsequent histopathological examination from the nodules showed benign spindle cells in a Periodic acid Schiff-positive myxoid background. The disease has a relentlessly progressive course, with most patients surviving only up to the 4 th decade. As of now, there is no specific treatment for this disorder. Genetic counseling is essential to explain to parents about a 25% chance of having a diseased baby in any pregnancy. With the gene being mapped recently, techniques for antenatal diagnosis are likely to be established.

    Juvenile Dermatomiositis (JD) is autoimmune disease that progresses with time; JD's main differentiated syndromes are rash on the skin, poor function of muscles, and often developing invalidism. If the health practitioners manage to diagnose the JD on an early stage and prescribe the adequate treatment the disease will not progress aggressively. This approach is tangible for practical rheumatology and pediatric. The article aims to present the reasons of the development of the JD and calcinosis. The study based on the description of the patients with JD. There are distinguished the main symptoms of the disease in children: frequent and acute developments of muscles calcinosis, occasionally with diffuse character followed with hypotrophy of the muscles, contractures and invalidism. One of the patient cases that describe the article is the thirteen-year boy with JD indicating repeated sequence of the disease, with diffusive calcinosis, cellulitis followed with secondary infection and impaired vision.

    Full Text Available Juvenile Idiopathic Arthritis (JIA is the most chronic musculoskeletal disease of pediatric population. The chronic course of disease has a great impact on oral health. Temporomandibular joint is involved in JIA causing limited mouth opening with progressive open bite, retrognathia, microgenia and bird like appearance. Joints of upper and lower extremities are also involved. Effect on upper limb function leads to difficulty with fine motor movements required for brushing and flossing. This increases incidence of caries and periodontal disease in children. The cause of JIA is still poorly understood and none of the available drugs for JIA can cure the disease. However, prognosis has improved as a result of progress in disease classification and management. The dental practitioner should be familiar with the symptoms and oral manifestations of JIA to help manage as multidisciplinary management is essential.

    Limited information exists on juvenile homosexual homicide (JHH), that is, youths who perpetrate sexual homicides against same-sex victims. Only a handful of cases from the United States and internationally have been described in the literature. This study, the first of its kind, examines the epidemiology, victimology, victim-offender relationship, and weapon-use patterns in JHH offenders using a large U.S. database on homicide spanning three decades. The data for this study were derived from the Federal Bureau of Investigation's Supplementary Homicide Reports (SHRs) for the years 1976 through 2005. A total of 93 cases of JHH were identified. On average, three of these crimes occurred annually in the U.S., and there was a marked decline in its incidence over the study period. Ninety-five percent were male offender-male victim cases and 5% were female offender-female victim cases. JHH offenders were over-represented amongst all juvenile sexual murderers, similar to their adult counterparts. The majority of these boys were aged 16 or 17 and killed adult victims. They were significantly more likely to kill adult victims than other age groups, to be friends or acquaintances of the victims, and to use contact/edged weapons or firearms. Most offenders killed same-race victims, although Black offenders were significantly more likely than White offenders to kill interracially. A case report is provided to illustrate JHH. Further research is needed to promote our understanding of the pathogenesis, etiology, and associated risk factors for this aberrant form of murder by children.

    There is not yet a commonly accepted, standardized approach in the treatment of juvenile idiopathic uveitis when initial steroid therapy is insufficient. We sought to assess current practice patterns within a large cohort of children with juvenile uveitis. This is a cross-sectional cohort study of patients with uveitis enrolled in the Childhood Arthritis and Rheumatology Research Alliance (CARRAnet) registry. Clinical information including, demographic information, presenting features, disease complications, and medications were collected. Chi-square and Fisher's exact tests were used to assess for associations between medications and clinical characteristics. Ninety-two children with idiopathic and 656 with juvenile idiopathic arthritis (JIA)-associated uveitis were identified. Indication (arthritis or uveitis) for medication use was not available for JIA patients; therefore, detailed analysis was limited to children with idiopathic uveitis. In this group, 94 % had received systemic steroids. Methotrexate (MTX) was used in 76 % of patients, with oral and subcutaneous forms given at similar rates. In multivariable analysis, non-Caucasians were more likely to be treated initially with subcutaneous MTX (P = 0.003). Of the 53 % of patients treated with a biologic DMARD, all received a tumor necrosis factor (TNF) inhibitor. TNF inhibitor use was associated with a higher frequency of cataracts (52 % vs 21 %; P = 0.001) and antinuclear antibody positivity (49 % vs 29 %; P = 0.04), although overall complication rates were not higher in these patients. Among idiopathic uveitis patients enrolled in the CARRAnet registry, MTX was the most commonly used DMARD, with subcutaneous and oral forms equally favored. Patients who received a TNF inhibitor were more likely to be ANA positive and have cataracts.
