BACKGROUND/AIMS Bevacizumab and ranibizumab are routinely used to treat diabetic macular edema (DME). We aim to evaluate the usefulness of switching to ranibizumab therapy following bevacizumab treatment failure in eyes with DME. METHODS We performed a retrospective analysis of a consecutive group of patients with DME who received ranibizumab injections following the failure of bevacizumab in...
PURPOSE To explore the correlation between optical coherence tomography (OCT) and stereoscopic fundus photographs (FP) for the assessment of retinal thickening (RT) in diabetic macular edema (DME) within a clinical trial. METHODS OCT, FP, and best corrected visual acuity (VA) measurements were obtained in both eyes of 263 participants in a trial comparing two photocoagulation techniques for D...
purpose: to compare the preoperative and postoperative measurement of intraocular pressure (iop) using goldman applanation tonometry (gat), the air puff and pascal dynamic contour tonometers (pdct) in eyes undergoing myopic and myopic astigmatic photorefractive keratectomy (prk). methods: in a descriptional -analytic and prospective study, a complete examination was performed at the slit lamp, ...
We aimed to determine normal macular thickness using Cirrus high definition optical coherence tomography. In this cross-sectional survey, 112 subjects were selected using random sampling from the Rasht telephone directory. All subjects underwent complete eye examinations. Both eyes of each patient were evaluated. The creation of a macular thickness map using a macular cube 512 × 128 combo was o...
Older adults experience impairments in episodic memory, ranging from mild to clinically significant. Given the critical role of the medial temporal lobe (MTL) in episodic memory, age-related changes in MTL structure and function may partially account for individual differences in memory. Using ultra-high-field 7T structural MRI and high-resolution 3T functional MRI (hr-fMRI), we evaluated MTL s...
INTRODUCTION We studied the automated intraretinal segmentation on Fourier domain optical coherence tomography (OCT). MATERIALS AND METHODS Thirty eyes from 30 normal subjects were studied using the RTVue-100. Both radial and raster scan protocol were performed 3 times on each subject. The OCT software performs automated intraretinal segmentation and provides macular thickness measurements. ...
The aim of present study was to analyze early postoperative changes in the macular area using optical coherence tomography (OCT) after uncomplicated glaucoma filtration surgery. This prospective study included 32 patients (34 eyes) with open-angle glaucoma, which underwent trabeculectomy with or without use of mitomycin C. Exclusion criteria were macular edema, uveitis, age-related macular dege...
