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 mm2 with software version 4 protocol in cir...

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...

Objective: Remote Ischemic Preconditioning (RIPC) as the transient ischemia and reperfusion of the arm is a promising method for protecting different tissue from future ischemia. These effects might be mediated through vascular and endothelial growth factor (VEGF) pathway. We investigated the influence of RIPC on diabetic macular edema (DME) as a chronic ischemic condition in patients who were ...

PURPOSE To determine the effect of phacoemulsification on macular volume and thickness using spectral domain optical coherence tomography examinations. METHODS Twenty-seven eyes of 27 subjects who underwent phacoemulsification were studied. All nine areas of the macula were examined by spectral domain optical coherence tomography preoperatively and 2 months postoperatively. Effective phacoemu...

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, ...

Objective: To determine whether fingolimod, an oral sphingosine-1-phosphate receptor modulator approved for treatment of multiple sclerosis (MS), generally leads to increased retinal tissue volume. Methods: In this longitudinal observational study, we compared changes in macular volume on spectral-domain optical coherence tomography (OCT) between consecutive patients with MS who initiated fingo...

AIM To investigate the difference of retinal nerve fiber layer (RNFL) thickness and macular fovea thickness/volume between multiple sclerosis (MS) patients and healthy normal individuals using optical coherence tomography (OCT) and assess its association with visual field parameters. METHODS Thirty consecutive MS patients and 28 healthy controls were recruited in this prospective study. Compr...

BACKGROUND There is conflicting evidence as to whether Alzheimer disease (AD) is accompanied by loss of retinal ganglion cells. To evaluate this issue, we have used optical coherence tomography (OCT) to assess the thickness and volume of the retina. We have also sought to correlate our findings with visual function and cognitive impairment. METHODS We evaluated 28 eyes of 14 patients with AD ...

BACKGROUND The influence of serous retinal detachment (SRD) on retinal sensitivity in patients with branch retinal vein occlusion (BRVO) and macular edema remains unclear. This is despite the frequent co-existence of SRD and cystoid macular edema (CME) in BRVO patients on optical coherence tomography (OCT) and the fact that CME is the most common form of macular edema secondary to BRVO. We inve...
