Laser photocoagulation has been used successfully for the treatment of clinically significant macular oedema to reduce the risk of loss of vision in diabetic patients. A quantitative method for measuring retinal thickness was applied to 20 patients with diabetic macular oedema before and 4 months after focal laser treatment to assess the reduction in retinal thickening and its relation to visua...

PURPOSE Recently demonstrated neuronal loss in the inner nuclear layer of the retina in multiple sclerosis (MS) and glaucoma raises the question of a primary (possibly immune-mediated) or secondary (transsynaptic) mechanism of retinal damage in these diseases. In the present study we used optical coherence tomography to investigate retrograde retinal transsynaptic degeneration in patients with ...

PURPOSE To investigate retinal changes prior to vascular signs in patients with type 2 diabetes without diabetic retinopathy or with mild non proliferative diabetic retinopathy. METHODS A cross-sectional study was performed in three groups: patients without diabetes, patients with type 2 diabetes without diabetic retinopathy, and patients with diabetes with mild diabetic retinopathy. Analysis...

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 examine the topographic correlation between retinal morphology and retinal sensitivity by mesopic and scotopic fundus-controlled perimetry (FCP) in eyes with intermediate AMD. Methods Thirty-five eyes from 32 patients (mean age 70.9 years) and 29 age-matched controls prospectively underwent spectral-domain optical coherence tomography (SD-OCT) imaging. Mesopic (Goldman III, 200 ms,...

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...

Purpose: The present study aimed to review the effect of dehydration during Ramadan fasting on the health and ocular parameters leading to changes in eye function. Methods: Articles included in the study were taken from Pub Med, Ovid, Web of Science and Google Scholar up to 2014.Related articles were also obtained from scientific journals in fasting and eye. Results: Dehydration and nutrition c...

OBJECTIVE To examine differences in individual retinal layer thicknesses measured by spectral domain optical coherence tomography (SD-OCT) (Spectralis®) produced with age and according to sex. DESIGN Cross-sectional, observational study. METHODS The study was conducted in 297 eyes of 297 healthy subjects aged 18 to 87 years. In one randomly selected eye of each participant the volume and me...

PURPOSE To assess the relationship between the retinal thickness analyzer (RTA) parameters, and those of the GDx VCC scanning laser polarimeter (GDx VCC), Stratus OCT optical coherence tomography (Stratus OCT), and Heidelberg retinal tomograph II confocal scanning laser ophthalmoscopy (HRT II). METHODS Twenty-nine primary open-angle glaucoma patients were retrospectively included in this stud...

PURPOSE To determine the diagnostic ability of retinal vessel diameter (RVD) measurements and the factors related to retinal vascular diameters in patients with open-angle glaucoma (OAG). METHODS This retrospective observational study included 145 patients with OAG (63 with high-tension and 82 with low-tension glaucoma) and 60 healthy controls. The central retinal arteriolar equivalent (CRAE)...
