OBJECTIVES To investigate optical coherence tomography consistency on foveal thickness, foveal volume, and macular volume measurements in patients with and without diffuse diabetic macular edema. INTRODUCTION Optical coherence tomography represents an objective technique that provides cross-sectional tomographs of retinal structure in vivo. However, it is expected that poor fixation ability, ...

Background: optical coherence tomography is one of the most valuable imaging techniques in the evaluation of macula. Objective: to investigate the repeatability and reproducibility of OCT  in measuring the macular thickness in normal eyes before and after pupil dilation. Methods: A total of 44 eyes were enrolled. All subjects underwent macular thickness measurement using the Cirrus SD-OCT ma...

OBJECTIVE To compare the macular ganglion cell complex (GCC) with peripapillary retinal fiber layer (RNFL) thickness map in glaucoma suspects and patients. SUBJECTS AND METHODS Forty participants (20 glaucoma suspects and 20 glaucoma patients) were enrolled. Macular GCC and RNFL thickness maps were performed in both eyes of each participant in the same visit. The sensitivity and specificity o...

Statement: This study was conducted to determine the properties for thickness map of 11 retinal layers in fovea and 8 surrounding sectors. Retinal boundaries were determined automatically and the thickness results were compared between genders and for variety of ages. Abstract Purpose. This study was conducted to determine the thickness map of eleven retinal layers in normal subjects by spectra...

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...
