PURPOSE: To evaluate the efficacy of pars plana vitrectomy (PPV) as an anti-inflammatory therapy in pediatric recurrent intermediate uveitis. METHODS: A retrospective study evaluated the long-term results of PPV indicated for intermediate uveitis with a mean observation period of 10.3 years (range 7-15.6 years) in 6 children (mean age 8 years, range 6-12 years). Pars plana vitrectomy was performed on 10 eyes in the standard manner and was initiated by vitreous sampling for laboratory examination...

PURPOSE: To report a case of a neurofibromatosis Type 2 with unusual clinical features. METHODS: Observational clinical case report. RESULTS: A 22-year-old woman was referred with bilateral blurred vision and macular "scars." Ocular examination revealed bilateral posterior subcapsular and cortical cataract, optic disk swelling, hyperpigmented macular lesions, epiretinal membrane, and macular temporal dragging. Spectral-domain optical coherence tomographic imaging showed bilateral epiretinal membranes, peripapillary nerve fiber layer thickening, and vitreoretinal tractional bands...

PURPOSE: To investigate the significance of difference in straylight of cataract eyes with different morphologies, as a function of age and visual acuity. METHODS: A literature review to collect relevant papers on straylight, age, and visual acuity of three common cataract morphologies leads to including five eligible papers for the analysis. The effect of morphology was incorporated to categorize straylight dependency on the two variables. We also determined the amount of progression in a cataract group using a control group...

REVIEW
Daisy Y Shu, Frank J Lovicu
Wound healing is one of the most complex biological processes to occur in life. Repair of tissue following injury involves dynamic interactions between multiple cell types, growth factors, inflammatory mediators and components of the extracellular matrix (ECM). Aberrant and uncontrolled wound healing leads to a non-functional mass of fibrotic tissue. In the eye, fibrotic disease disrupts the normally transparent ocular tissues resulting in irreversible loss of vision. A common feature in fibrotic eye disease is the transdifferentiation of cells into myofibroblasts that can occur through a process known as epithelial-mesenchymal transition (EMT)...

This study aimed to identify the type of cataract opacity associated with subjective sleep quality for cataract patients. A total of 180 consecutive patients (average age 74.2 years) underwent cataract surgery with implantation of an ultraviolet-blocking or blue light-blocking intraocular lens. The participants' subjective sleep quality was evaluated using the Pittsburgh sleep quality index (PSQI) before and at 2 months after surgery. Patients were divided into two groups for analysis: normal sleepers (preoperative PSQI ≤5) and poor sleepers (preoperative PSQI ≥6)...

OBJECTIVE: To examine the relationship between occupational exposure to ionizing radiation and the prevalence of lens changes in interventional cardiologists (ICs) and catheterization laboratory ("cath-lab") staff. BACKGROUND: Exposure to ionizing radiation is associated with the development of lens opacities. ICs and cath-lab staff can receive high doses of ionizing radiation without protection, and may thus be at risk for lens opacity formation. METHODS: We conducted a cross-sectional study at an interventional cardiology conference...

PURPOSE: To evaluate the relationship between gout and age-related cataracts (ARCs). METHODS: A comprehensive literature search of the PubMed and Web of Science databases was conducted to identify papers on the association between gout and cataract risk that had been published between February 1991 and January 2017. Pooled relative risks (RRs) or odds ratios (ORs) and their corresponding 95% confidence intervals (CIs) were calculated. The random-effects model was used instead of the fixed-effects model when heterogeneity was identified, as indicated by a Cochran's Q statistic P-value <0...

PURPOSE: 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. METHODS: 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...

A 50-year-old male patient presented to the neuro-ophthalmology clinic with chief complaints of gradual decrease in vision in both eyes, more in the left eye, for 6 years. On general examination, the patient had a hemiplegic gait. His presenting acuity was 20/50 in the right eye and 20/320 in the left eye, not improving further. He had dense posterior subcapsular cataracts in both eyes, and fundus examination revealed pale discs. Humphrey visual field tests 30-2 revealed a vertical nasal midline defect in the right eye and grossly depressed fields in the left eye...

Purpose: Posterior subcapsular cataract (PSC) is a frequent complication in patients with retinitis pigmentosa (RP). The risk factors for PSC formation in RP are largely unknown. The purpose of this study was to investigate the risk factors for PSC. Methods: We retrospectively studied a total of 322 eyes of 173 patients who were diagnosed with typical RP. We considered the following possible risk factors for PSC: age, sex, hypertension, diabetes mellitus, high myopia, asthma, history of steroid intake, and aqueous flare...

BACKGROUND: Cataracts are generally known to occur in hyperglycemic conditions in diabetic patients. In this case, cataract occurred in the course of glucose level control in a patient who had been in a hyperglycemic state. CASE PRESENTATION: A 42-year-old Korean man who had uncontrolled diabetes for more than a year presented with bilateral posterior subcapsular cataracts, which developed within days of initiating antihyperglycemic therapy. With control of his serum glucose level for several weeks, the cataracts regressed...

PURPOSE: To identify ocular factors that affect signal strength in spectral-domain optical coherence tomography (SD-OCT). METHODS: Data from 1312 participants of the population-based Singapore Malay Eye Study-2 (SiMES-2) were included in the analysis. All participants underwent standardized ophthalmic examination, including measurements of best-corrected visual acuity (BCVA), refractive error, axial length, corneal curvature and presence of cataracts. Optic disc and macular cube scans were acquired using the Cirrus HD-OCT (software version 6...
