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...

Purpose To test the hypothesis that macular choroidal thickness is lower in patients with pseudoexfoliation syndrome (PXS) as compared to healthy control subjects. Methods In this cross-sectional, observational study, 38 non-glaucomatous PXS subjects and 37 healthy volunteers were enrolled in a tertiary care Glaucoma Clinic. The macular region was scanned with the enhanced depth imaging (EDI)...

The Purpose of this study was to evaluate the efficacy of IVTA as rescue therapy in patients with DME refractory to intravitreal ranibizumab. This is a prospective interventional non-comparative study that included diabetic patients with persistent CSME and associated visual loss despite previous treatment with intravitreal ranibizumab. Main outcome measures were improvement of BCVA 3 Snellen l...

PURPOSE To determine the repeatability of Stratus optical coherence tomography (OCT) measures of retinal thickness and volume in patients with neovascular age-related macular degeneration (nAMD) METHOD: Fifty-one eyes of 51 consecutive patients with nAMD underwent an OCT imaging session in which two fast macular thickness map (FMTM) protocol scans sets were acquired by a single experienced oper...

BACKGROUND The purpose of this study was to evaluate the incidence and amount of macular edema by optical coherence tomography (OCT) after combined small gauge sutureless vitrectomy with phacoemulsification and intravitreal triamcinolone. METHODS This retrospective case series included 194 consecutive eyes undergoing nonemergent vitrectomy with phacoemulsification and intravitreal triamcinolo...

PURPOSE To integrate parameters on spectral-domain optical coherence tomography (SD-OCT) in diabetic retinopathy (DR) based on the self-organizing map and objectively describe the macular morphologic patterns. METHODS A total of 336 consecutive eyes of 216 patients with DR for whom clear SD-OCT images were available were retrospectively reviewed. Eleven OCT parameters and the logarithm of the...

purpose: to evaluate the rate of optical coherence tomography (oct) grid decentration in a routine practice and its effect on thickness measurements methods: topcon spectral domain oct scans from various macular diseases including age related macular degeneration, diabetic macular edema, macular pucker and central serous chorioretinopathy (cscr) were studied in all patients visited during seven...

OBJECTIVE To evaluate optical coherence tomography (OCT) measurements and methods of analysis of OCT data in studies of diabetic macular edema (DME). DESIGN Associations of pairs of OCT variables and results of 3 analysis methods using data from 2 studies of DME. PARTICIPANTS Two hundred sixty-three subjects from a study of modified Early Treatment of Diabetic Retinopathy Study (mETDRS) ver...

we aimed determine normal macular thickness by using cirrus hd-oct in  rasht city, iran. in this cross-sectional survey, 112 were selected with random sampling. all subjects underwent complete eye examinations. both eyes of each patient were evaluated. optional protocol was macular thickness map with macular cub 512×128 and the average thickness of the retina was determined in 9 etdrs regions. ...
