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 measure macular thickness in normal subjects with respect to age and gender using cirrus hd-oct in rasht city. methods: in this cross-sectional study, 112 normal subjects were randomly selected. both eyes of each subject were included and all subjects underwent complete eye examinations. macular thickness map protocol with macular cube 512×128 was selected, and the average thickness...

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. ...

purpose: to evaluate the effectiveness of pars plana vitrectomy and posterior hyaloid stripping in decreasing macular thickness and improving vision in diabetic macular edema.          methods: this prospective interventional case series includes 30 eyes of 25 diabetic patients with diabetic macular edema with macular thickness exceeding 170 microns and thickened posterior hyaloid. bcva and mac...

purpose: to evaluate the influence of different confounding factors on the effect of intravitreal triamcinolone acetonide injection for refractory diabetic macular edema. methods: in a prospective placebo-controlled randomized clinical trial, 88 eyes with refractory diabetic macular edema were randomly assigned into two groups including 45 in the treatment group (4 mg intravitreal triamcinolone...

Assessment of the peripapillary nerve fiber layer and macular thickness can be determined in ophthalmology using optical coherence tomography (OCT). Decreased nerve fiber layer thickness and macular ganglion cell thickness in optic nerve ischemia have been correlated with visual field loss. OCT allows deep optic nerve head evaluation which helps understand pathophysiology of diseases.  Furtherm...

purpose: one of the major causes of visual acuity loss in diabetic patients is diabetic macular edema (dme). best-corrected visual acuity and central macular thickness changes are considered as two main outcomes in diabetic macular patients. the goal of this study was to compare the effect of intravitreal bevacizumab injection alone or combined with triamcinolone versus macular photocoagulation...

purpose : to determine the nerve fiber layer and macular thickness by optical coherence tomography (oct) in emmetropic, high-myopic and high-hyperopic eyes methods : one hundred five eyes of 55 randomly selected healthy subjects between 20 and 30 years old were included in this study. the eyes were categorized in three groups (high-myopic, emmetropic and high-hyperopic) according to their cyclo...
