Visual function and retinal morphology were investigated to elucidate the influence of ischemia in patients with branch retinal vein occlusion (BRVO) and macular edema. In 41 consecutive patients with BRVO aged 68.9 ± 10.0 years (22 women and 19 men), the area of capillary nonperfusion was measured by fluorescein angiography. Retinal thickness and retinal volume were measured by optical coheren...

BACKGROUND Macular edema is a common cause of visual loss at uveitic patients. The aim of our study was to investigate retinal and choroidal thickness at the macula in anterior (AU) and intermediate (IMU) uveitis and in healthy individuals using spectral domain optical coherence tomography (SD-OCT). METHODS Case-control study of 21 patients with AU and 23 patients with IMU and 34 age-matched ...

PURPOSE To identify individual retinal layer thickness changes associated with visual acuity gain in diabetic macular edema treated with ranibizumab using layer segmentation on high-resolution optical coherence tomography scans. METHODS Retrospective observational case series. Thirty-three treatment-naive eyes with diabetic macular edema were imaged by spectral domain optical coherence tomogr...

PURPOSE To evaluate vitrectomy for diabetic macular edema (DME) in eyes with at least moderate vision loss and vitreomacular traction. DESIGN Prospective cohort study. PARTICIPANTS The primary cohort included 87 eyes with DME and vitreomacular traction based on investigator's evaluation, visual acuity 20/63-20/400, optical coherence tomography (OCT) central subfield >300 microns and no conc...

A 10-year-old Malay girl with underlying HbE/beta-thalassemia, on regular blood transfusion and deferoxamine iron chelation therapy, presented two-month history of bilateral blurring vision. On examination, her vision was 6/36 both eyes. Other optic nerve functions were normal. Anterior segment examination eyes unremarkable. Fundus revealed dull foveal reflex. Optical coherence tomography macul...

Purpose: To describe the macular thickness map of Iranian adult with normal retinal status as measured by Cirrus’ optical coherence tomography (OCT) instrument Methods: In this cross-sectional study, one eye of subjects with normal ocular examination and retinal status of at least one eye were recruited. The 512×128-scan pattern and scan area of 6×6 mm 2 with software version 4 protocol in Cirr...

purpose: to compare central corneal thickness (cct) measured by galilei and orbscan ii with that by ultrasonic (u/s) pachymetry in unoperated eyes. methods: cct was measured in 184 unoperated eyes of 92 healthy retractive surgery candidates using galilei, orbscan ii, and u/s pachymetry. considered as a benchmark, measurements by u/s pachymetry were compared to those obtained by the other two de...

PURPOSE To record the normative values for macular thickness and macular volume in normal Nepalese eyes. METHODS In all, 126 eyes of 63 emmetropic subjects (mean age: 21.17±6.76 years; range: 10-37 years) were assessed for macular thickness and macular volume, using spectral domain-optical coherence tomography over 6×6 mm(2) in the posterior pole. A fast macular thickness protocol was employe...

purpose: to compare thickness of central cornea measured using pentacam, orbscan ii, and ultrasound pachymeter methods: patients with no history of corneal diseases or systemic diseases affecting eyes, who did not wear contact lens or use eye medications, and who with no previous history of corneal surgery were selected for this study. central corneal thickness (cct) was measured by three metho...
