PURPOSE To assess the test-retest variability of central and sectorial macular thickness measurements obtained by Cirrus HD-OCT (Carl Zeiss Meditec, Dublin, CA) in neovascular age-related macular degeneration (nAMD). METHODS Macular thickness measurements of nine standard ETDRS subfields were obtained and analyzed. The repeatability of macular thickness measurements by Cirrus HD-OCT was asses...
OBJECTIVE To present the clinical spectrum of lamellar macular defects and describe the different subtypes based on their optical coherence tomography (OCT) configuration and visual prognosis. METHODS The retrospective observational case series reviewed OCT scans of 92 eyes with lamellar macular defects. Lamellar macular defects were categorised into subtypes of macular pseudohole (MPH), lame...
BACKGROUND Diabetic macular edema (DME) is one of the manifestations of diabetic retinopathy leading to loss of central vision and visual acuity. It manifests itself with swelling around the central part of the retina, the area responsible for sharp vision. Current treatment includes laser therapy and intravitreal steroids with preventative measures including diabetes control. No one treatment ...
This study was performed to evaluate optic disc appearance, retinal nerve fiber layer (RNFL) thickness, and macular thickness in normal, ocular hypertensive (OHT) and glaucomatous eyes using optical coherence tomography (OCT) 3000. One hundred fifty-eight eyes of 167 consecutive subjects were enrolled: 60 normal, 53 OHT, and 54 glaucomatous. OCT topographic parameters of cup diameter, cup area,...
BACKGROUND We present a case of a macular hole formation and its spontaneous closure after vitrectomy for vitreomacular traction. To our knowledge, it is the first description of spontaneous closure of the macular hole after vitrectomy for vitreomacular traction. CASE PRESENTATION A 78-year-old woman presented decreased visual acuity and metamorphopsia in the right eye due to vitreomacular tr...
The aim of present study was to analyze early postoperative changes in the macular area using optical coherence tomography (OCT) after uncomplicated glaucoma filtration surgery. This prospective study included 32 patients (34 eyes) with open-angle glaucoma, which underwent trabeculectomy with or without use of mitomycin C. Exclusion criteria were macular edema, uveitis, age-related macular dege...
Purpose: To report a quick reopening of a spontaneously closed full thickness macular hole. Design: Case report. Methods: A 68-year-old patient with stage III full thickness idiopathic macular hole in one eye was followed up for thirteen months with fundus photography and optical coherence tomography (OCT). Results: Twelve days after the first examination, that detected the macular hole, OCT sc...
BACKGROUND Acute severe postoperative endophthalmitis may lead to severe vision loss. The aim of this study was the analysis of macular microstructure imaged by spectral domain optical coherence tomography in patients after pars plana vitrectomy due to postcataract endophthalmitis. METHODS A cross sectional study was carried out in 17 patients who had cataract surgery in both eyes and underwe...
BACKGROUND The aim of this study was to evaluate the effect of uneventful phacoemulsification on the morphology and thickness of the macula, the submacular choroid, and the peripapillary choroid. METHODS In 14 eyes from 14 patients, retinal macular thickness, choroidal submacular thickness, and choroidal peripapillary thickness were measured preoperatively and at one week and one month after ...
