PURPOSE: To assess the proportion of pure anisometropic amblyopia in a sample Iranian (white) population. METHODS: A total of 2800 consecutive individuals who presented at a referral eye clinic for any reason were examined for the presence of pure anisometropic amblyopia. Anisometropia was reported when a spherical equivalent refraction difference of at least 1.0 D with or without a cylinder refraction difference of at least 1.0 D was present between the two eyes...

PURPOSE: Transscleral cyclodiode laser cyclophotocoagulation (TSCP) is often reserved for treatment of refractory glaucoma. This retrospective study investigates the safety and efficacy of TSCP among the Chinese population. METHODS: A retrospective review was performed on electronic patient records of all patients receiving TSCP between years 2009 to year 2016. Patient demographics, indication for laser, success and response rate, change in intraocular pressure (IOP), number of treatment sessions, laser energy, glaucoma medication, visual acuity, pain symptoms and complication rate were documented...

PURPOSE: To evaluate the effects of retinitis pigmentosa (RP) on time, frequency, and time-frequency components of Xenon flash ERG signals using Fourier and wavelet transforms. METHODS: Xenon flash ERG was done in 18 eyes of nine RP patients and 20 normal eyes. After examining latency and amplitude, Fourier and wavelet transforms were performed using MATLAB software. Then, we extracted the mode frequency from the Fourier transform and main frequencies and their occurrence time from the wavelet transform...

REVIEW
Alexandre de Carvalho Mendes Paiva, Adenilson de Souza da Fonseca
Selective laser trabeculoplasty (SLT) has been used for treatment of primary open-angle glaucoma, ocular hypertension, pigmenter and pseudoexfoliative glaucoma being considered a low-risk procedure. Therefore, transitory and permanent adverse effects have been reported, including corneal changes, subclinical edema, and reduction in endothelial cells and in central corneal thickness. Despite rarer, serious corneal complications after SLT can be permanent and lead to visual impairment, central corneal haze, opacity and narrowing...

PURPOSE: The present study aimed to evaluate the potential corneal endothelial cell toxicity of trypan blue (TB) and Brilliant Blue G (BBG), two dyes used to stain the anterior capsule in cataract surgery. METHODS: We conducted a single-center, prospective, randomized study in which 150 eyes of 117 patients were randomly divided into control (CT), TB, and BBG groups. Preoperative and postoperative (1, 3, and 6 months) values for corrected distance visual acuity (CDVA), corneal endothelial cell count, and central corneal thickness were compared among the three groups...

BACKGROUND: To evaluate the clinical results of standard, transepithelial (TE) and iontophoresis (I) corneal cross-linking (CXL), in patients with progressive keratoconus. METHODS: Thirty eyes of 30 patients with progressive keratoconus treated by CXL (10 by standard-CXL, 10 by TE-CXL and 10 by I-TE-CXL) with 12 months of follow-up. Pre- and postoperative ophthalmologic testing were: uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), refractive examination (spherical error, spherical equivalent), corneal topography (corneal astigmatism, simulated maximum, minimum and average keratometry), aberrometry (coma and spherical aberration), pachymetry and endothelial cell density...

PURPOSE: To compare the two-year outcomes of non-penetrating deep sclerectomy (NPDS) and Ex-PRESS glaucoma shunt. METHODS: A retrospective chart review of patients who had undergone NPDS or Ex-PRESS since 2012 was conducted. Patients were excluded if they had undergone eye surgery other than cataract extraction, were diagnosed with ocular pathology other than glaucoma or had less than two-year follow-up. Pre- and postoperative visual acuity, intraocular pressure (IOP), number of hypotensive drugs and visual fields were recorded, as well as intra- and postoperative complications...

PURPOSE: In this study, by using a two-dimensional (2D) electrophoresis-based experimental approach, we aimed at understanding the nature of alkali injuries and the underlying mechanisms. A secondary aim was to compare the effects of cross-linking (CXL) and amnion membrane transplantation (AMT) on corneal protein compositions at the end of the early repair phase after injured with alkali.

PURPOSE: We aimed to compare the neuroprotective effects of brimonidine tartrate (BRT) and melatonin (MEL) on retinal ganglion cells (RGCs) in a rat glaucoma model. METHODS: Thirty-six adult Wistar albino rats were allocated into six groups: control (C), glaucoma (G), BRT, MEL, G + BRT and G + MEL. After establishing the glaucoma model, intraocular pressure (IOP) of all animals measured at day 4 and day 30 was compared statistically with day 0 and day 4, respectively...

PURPOSE: To assess variability in the coefficient of variation (COV) in cell area estimates when using different numbers of cells for endothelial morphometry. METHODS: Using non-contact specular microscopy images of the corneal endothelium, 4 sets of 20 cases were selected that included 200 cells and had overall (global) COV values of less than 30 (group 1), 31-40 (group 2), 41-50 (group 3) and over 50% (group 4). Subjects could be normal, or had ophthalmic disease (such as diabetes), a history of rigid or soft contact lens wear or were assessed after cataract surgery...
