AIMS To evaluate the scanning retinal thickness analyser (RTA), a novel non-invasive imaging instrument, in diagnosing and quantitatively characterising diabetic macular oedema, and to investigate the relation between central macula thickness measured by RTA and other clinical examinations. METHODS Central macular thickness was measured using the RTA in 40 normal subjects and 60 patients with...

PURPOSE To report an asymmetry analysis of macular inner retinal layers using swept-source optical coherence tomography (OCT) and to evaluate the utility for glaucoma diagnosis. DESIGN Observational, cross-sectional study. PARTICIPANTS Seventy normal healthy subjects and 62 glaucoma patients. METHODS Three-dimensional scans were acquired from 70 normal subjects and 62 open angle glaucoma ...

OBJECTIVE To determine macular volume and central foveal thickness measurements in normal eyes of healthy Nigerian adults using Stratus optical coherence tomography. SUBJECTS AND METHODS Consenting 100 adults Nigerians with normal eyes were recruited and examined using Carl Zeiss Stratus Optical Coherence Tomographer (OCT) machine Model 3000 software version 4.0. A fast macular thickness map ...

OBJECTIVE The purpose of the study was to investigate if absolute values and reproducibility of thickness maps obtained from 2 optical coherence tomography (OCT) scanning protocols, regular high-resolution and fast low-density mode, differ in patients with diabetic macular edema. METHODS A total of 26 consecutive patients undergoing fluorescein angiography and Stratus OCT scanning for the eva...

PURPOSE To compare macular thickness of the normal fellow eye to that of the amblyopic eye using optical coherence tomography (OCT) in children with unilateral high myopia. Relationships between macular thickness and magnitude of myopic anisometropia, axial length, and visual acuity (VA) were investigated. METHODS Thirty-one children with a mean age of 9.56 years were recruited. Macular thick...

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...

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...

We retrospectively reviewed the records of 142 eyes of 138 patients with idiopathic full-thickness macular hole. Spontaneous closure of idiopathic full-thickness macular hole was observed in five eyes (3.5%) of four patients before the planned vitrectomy. In the era when surgical treatment was not available for macular hole, the rate of spontaneous closure of idiopathic full-thickness macular h...

PURPOSE We examined the relationship between relative afferent pupillary defects (RAPDs) and macular structural damage measured by macular thickness and macular ganglion cell-inner plexiform layer (mGCIPL) thickness in patients with glaucoma. METHODS A cross-sectional study was done of 106 glaucoma patients and 85 healthy individuals from the Diagnostic Innovations in Glaucoma Study. All subj...

INTRODUCTION Peripapillary retinal nerve fiber layer (RNFL) thickness analysis is a subjective method of analysis of glaucomatous damage. As almost 50% of retinal ganglion cells are located in the macula, assessment of macular thickness can be an alternative method for diagnosis of glaucoma. OBJECTIVES To evaluate the changes in macular and retinal nerve fiber layer thickness in controls, gla...
