PURPOSE: To evaluate subfoveal choroidal thickness (SCT) in cases with chronic rhegmatogenous retinal detachment (RRD), before and after pars plana vitrectomy, and cases with acute RRD using optical coherence tomography. METHODS: This retrospective study included 24 eyes with chronic RRD and 26 eyes with recent-onset RRD. Best corrected visual acuity, intraocular pressure, and SCT were measured and compared between the two groups. Of 24 eyes with chronic RRD, 11 had primary pars plana vitrectomy...

AIM: To evaluate the whether intravitreal erythropoietin (EPO) administration has any beneficial or adverse effect in patients with late-stage optic neuropathy (ON) or not. METHODS: The study examined 16 eyes of 16 patients who had late-stage ON and ≥1/20 best-corrected visual acuity (BCVA) in their affected eye. There were nonarteritic ischemic ON in 10 (62.5%) eyes, traumatic ON in 4 (25.0%) eyes and methanol-induced ON in 2 (12.5%) eyes. Using pars plana approach, 2000 IU/0...

PURPOSE: Critical flicker fusion (CFF) frequency is a well-studied test for evaluating demyelinating optic neuritis (ON). Its use in evaluating other optic neuropathies is not well established. The purpose of this study was to compare CFF in ON and non-arteritic anterior ischemic optic neuropathy (NAION). METHODS: We performed a retrospective review to compare multiple variables for eyes with ON or NAION using two-sided T tests and Chi-square tests. A multivariate linear regression was performed for the dependent variable CFF...

Vinod Kumar, Devesh Kumawat, Sabin Dhakal
The authors describe leukemic retinopathy with foveal leukemic infiltrates as the presenting feature of chronic myeloid leukemia. Spectral domain optical coherence tomography (SD-OCT) features of leukemic foveal infiltrates are presented. Though the retinopathy resolved with remission of disease, visual recovery was not complete due to loss of ellipsoid zone on SD-OCT.

PURPOSE: Diabetic macular edema (DME) is a major cause of visual impairment in patients with diabetes and is influenced by various systemic factors. This study evaluates the effect of renal status on DME using estimated glomerular filtration rate (eGFR) as a study marker. METHODS: This was a prospective observational cross-sectional study. One hundred and ninety-five patients of diabetic retinopathy (DR) were included. Group 1 had patients of DR without DME (n = 100), and group 2 had patients of DR with DME (n = 95)...

PURPOSE: Seasonal allergic conjunctivitis (SAC) is an inflammatory disease of the conjunctiva. Red cell distribution width (RDW) is a widely accepted inflammatory marker. We aimed to investigate whether RDW level is associated with the development of SAC in pediatric population. METHODS: The present study consisted of 90 subjects (45 children with SAC and 45 age- and sex-matched healthy children). The demographic findings, complete blood count parameters including RDW and laboratory parameters, were evaluated...

INTRODUCTION: Previous studies suggested that total serum bilirubin levels are negatively associated with diabetic retinopathy (DR) and nephropathy in patients with diabetes mellitus. The objective of this study was to explore the relationship between serum total bilirubin levels and prevalence of DR in patients with type 1 diabetes (T1DM) and normal renal function. METHODS: Study included 163 T1DM with normal renal function (urinary albumin excretion rate <30 mg/24 h, estimated glomerular filtration rate (eGFR) >60 ml min(-1)1...

PURPOSE: To report a case of keratitis caused by Providencia alcalifaciens. METHODS: A 70-year-old man presented with pain, redness, and decreased vision in both of his eyes. On initial presentation, the visual acuity in both of his eyes was hand motion, and slit lamp examination showed diffuse infiltrates and total epithelial defects of the cornea, conjunctival hyperemia, and severe anterior chamber reactions with 2-mm-height hypopyon. The results of laboratory studies revealed elevated liver function tests, which indicated the presence of alcoholic liver disease...

PURPOSE: To evaluate macular volume, retinal nerve fiber layer, and macular and peripapillary choroidal thickness in acromegaly patients. METHOD: In this prospective, case-control study, 31 patients with acromegaly and 32 healthy subjects were recruited. Only right eyes were evaluated. Macular choroidal thickness (CT) was measured at three points, peripapillary CT was measured at eight points, and macular volume was measured at nine areas in the central 6 mm circle zone by spectraldomain optical coherence tomography (OCT)...

PURPOSE: To study the Scheimpflug's imaging and corneal biomechanics in primary pterygium. METHODS: A prospective observational study of 55 patients with unilateral primary nasal pterygium was done. The normal fellow eyes of patients with pterygium were taken as controls. Clinical parameters noted included visual acuity, values of corneal curvature by doing Scheimpflug imaging, wavefront aberrations in terms of higher and lower-order aberrations and corneal hysteresis (CH) as well as corneal resistance factor (CRF) values by using ocular response analyzer...

PURPOSE: To describe the OCT angiography characteristics of flat irregular pigment epithelial detachments (PEDs), an overlapping tomographic feature of various macular disorders. METHODS: Consecutive patients with a dimpled retinal pigment epithelium profile on OCT, referred for a second opinion, were enrolled. Fluorescein (FA) and indocyanine green angiography (ICGA) were performed in all patients and compared to previous examinations, when available. In all patients, enhanced depth imaging-OCT and OCT angiography were performed upon referral and at subsequent follow-ups...

PURPOSE: The aim of this study is to report surgical outcomes in patients undergoing phacoemulsification surgery (PE) with versus without ophthalmic viscosurgical devices (OVDs). METHODS: This is a comparative case series study. In total, 145 patients who performed PE with OVDs in 68 eyes (Group 1) and without OVD in 77 eyes (Group 2) were enrolled. A comprehensive ophthalmological examination was performed including slit-lamp, fundus examination. Best-corrected visual acuity (BCVA), intraocular pressure (IOP) specular endothelial microscopy (SM), and ultrasound pachymetry (UP) were also measured before surgery and at four-time points postoperatively...

PURPOSE: To evaluate the relationship between glaucoma diagnosis and the nailfold capillaroscopy pattern in patients with systemic sclerosis. METHODS: An observational study in a cohort of patients with SSc was conducted. Patients with at least one nailfold videocapillaroscopy and one ophthalmology examination at the same year were included. Data collected were: age, sex; type of systemic sclerosis according to the degree of skin impairment, self-reported ethnicity, disease duration, current use and dosage of systemic corticosteroid, current use and dosage of bosentan(®), intraocular pressure, central corneal thickness, diagnosis of glaucoma and capillaroscopy pattern...
