To determine if reducing the area of internal limiting membrane (ILM) peeling in inverted ILM flap technique results satisfactory outcomes for repair large Stage IV idiopathic macular holes.Prospective comparative interventional study 87 consecutive eyes. Participants were randomized into two treatment groups. In Group A, classic was performed. B, a modification this procedure, temporal technique, modified restricted to side fovea only--the hole then covered with flap.There no significant...

To present the anatomical and functional results of vitrectomy with "inverted internal limiting membrane flap technique" in myopic macular holes without retinal detachment.A prospective interventional study 19 eyes a spherical equivalent >-6 diopters 18 consecutive patients. Preoperative postoperative visual acuity spectral domain optical coherence tomography images were evaluated. The main outcome measure was hole closure rate.Mean improved from 1.2 logMAR to 0.56 logMAR. We confirmed all...

The aim of this article was to estimate the natural course vitreomacular traction (VMT) disorder using high-resolution spectral-domain optical coherence tomography.Nineteen eyes 19 patients with idiopathic symptomatic VMT and who underwent tomographic follow-up examinations were included in retrospective observational study. average observation period all examination 8 months (±4.4 months). We observed microstructural changes macula position, length, vector forces attached vitreous macular...

Purpose: The aim of this study was to describe spectral domain optical coherence tomography characteristics and evolution non–full-thickness macular holes, with a bed retinal tissue present in the outer layers, which author will henceforth refer as holes (NFMHs). Methods: Retrospective observational 10,239 consecutive tomographic examinations conducted, select patients idiopathic NFMH. We measured following parameters: visual acuity, type NFMH, coexistence epiretinal membranes, photoreceptor...

Purpose . To report choroidal thickness and volume in healthy eyes using swept source optical coherence tomography (SS-OCT). Methods A prospective observational study of 122 patients examined with OCT (DRI-OCT, Topcon, Japan). In each eye, we performed 256 horizontal scans, 12 mm length centered on the fovea. We calculated manually a built-in caliper automatically DRI-OCT mapping software. Choroidal was also calculated. measured axial low-coherence reflectometry (Lenstar LS 900, Haag-Streit,...

To define the morphology of outer choroidal margins in swept-source optical coherence tomography.This is a prospective observational study 180 eyes: 20 eyes healthy volunteers, myopic patients, and from each following groups: macular hole, lamellar epiretinal membranes, drusen, dry age-related degeneration (AMD), neovascular AMD, vitreomacular traction. A single 12-mm wide tomography image for examined consisting 1,024 A-scans has been created. The main outcome measure selected was to...

Purpose To evaluate anatomic and functional results in patients with macular edema retinal vein occlusion (RVO), treated pars plana vitrectomy (PPV) internal limiting membrane (ILM) peeling, depending on the timing of surgery. Methods A total 35 consecutive underwent PPV ILM peeling. Visual acuity, fluorescein angiography, optical coherence tomography/spectral tomography were performed preoperatively 6–12 months postoperatively. Results Anatomic improvement was achieved 29 (82.9%). In 6...
