Abstract Purpose To investigate the relationship between metamorphopsia and retinal structural changes using optical coherence tomography angiography (OCTA) images before after macular hole (MH) surgery. Study design Retrospective, consecutive, case series. Methods Twenty-seven eyes of 27 patients undergoing MH surgery with internal limiting membrane peeling were studied. M-CHARTS (MC) was used to evaluate metamorphopsia. Retinal distances measured two sets vessel bifurcations that cross...

To evaluate the usefulness of spectral-domain optical coherence tomography (SD OCT)-determined ganglion cell complex thickness to total retinal ratio (G/T ratio) in diagnosing glaucoma.A 99 eyes with primary open-angle glaucoma and 35 normal were enrolled study. SD OCT (RTVue-100) was used measure macular thickness, outer circumpapillary nerve fiber layer (RNFL) thickness. A new parameter, G/T ratio, also calculated. The ability each parameter diagnose examined by analyzing area under...

Abstract Metamorphopsia is an important visual symptom of macular disease. We determined predictors for metamorphopsia investigating the relationships hole (MH) diameter and retinal layer thicknesses with after MH surgery. Forty-two eyes 42 consecutive patients undergoing surgery were retrospectively studied. was measured M-CHARTS. Inner nuclear (INL) outer (OR) 1000 μm away from central fovea at using Spectralis. Preoperative M-CHARTS scores correlated diameters (P = 0.007–0.031) changes...

To examine 1-year outcomes of metamorphopsia and tangential retinal displacement after epiretinal membrane surgery identify predictors for score at 1 year its improvement from baseline.M-CHARTS were used to measure metamorphopsia. Distances between the intersections two sets vessels measured with infrared or autofluorescence images. Predictors scores their differences baseline identified multivariate regression analysis.Ninety-two eyes 90 consecutive patients included. The vertical...

Purpose . To compare optical coherence tomography angiography (OCT-A) and laser speckle flowgraphy (LSFG) for the diagnosis of normal-tension glaucoma (NTG). Methods Twenty-eight eyes 28 patients with NTG 25 normal subjects matched age, refractive errors, systemic blood pressure, central corneal thickness were evaluated. OCT-A was used to measure whole image vessel density, inside disc peripapillary density; using LSFG, mean blur rate (MBR) optic nerve head (ONH) area (MBR A ), MBR V )...

To assess the relationship between macular ganglion cell complex and outer retinal thicknesses.Case-control study.Forty-two normal eyes 91 with primary open-angle glaucoma were studied.Spectral-domain optical coherence tomography (RTVue-100) was used to measure thickness. Ganglion thickness ratio also calculated.The relationships thicknesses evaluated.There a positive correlation in group (r = 0.53, P < 0.001 r 0.42, 0.001, respectively). In that respect, there no both groups -0.07, 0.657,...

Purpose . To evaluate the relationship between macular ganglion cell complex (mGCC) thickness, which is sum of retinal nerve fiber, cell, and inner plexiform layers, measured with a spectral-domain optical coherence tomograph optic head topography confocal scanning laser ophthalmoscope in glaucomatous eyes visual field defects localized predominantly to either hemifield. Materials Methods The correlation mGCC thickness hemispheres corresponding hemifields without (damaged intact hemispheres,...

We examined the influence of high myopia on conventional spectral-domain optical coherence tomographic parameters and assessed macular ganglion cell complex thickness to outer retinal ratio as a new tomography parameter.Prospective cross-sectional study.Sixty normal 30 highly myopic eyes (refractive error more than -6 D).We used RTVue-100 measure circumpapillary nerve fibre layer thickness, global loss volume, focal volume then calculated ratio.Each parameter was compared between two groups....

Purpose . To evaluate the relationships among optic nerve head (ONH) area, macular ganglion cell complex (mGCC) thickness, circumpapillary retinal fiber layer (cpRNFL) and visual field defects in patients with primary open angle glaucoma (POAG). Methods This retrospective study included 90 eyes of POAG. The ONH rim mGCC cpRNFL thickness were measured using optical coherence tomography. Mean deviation (MD) was standard automated perimetry. clinical factors including age, refraction, MD...

Purpose. We evaluated the association between optic nerve head (ONH) microcirculation and macular ganglion cell complex (mGCC) thickness in patients with untreated normal tension glaucoma (NTG) a hemifield defect. Methods. The medical records of 47 NTG were retrospectively reviewed. Laser speckle flowgraphy was used to obtain mean blur rate (MBR), relative measure blood flow. Average total deviation (TD), mGCC, circumpapillary retinal fiber layer (cpRNFL) also analyzed. Results. All...

The purposes of this study were to report the surgical success rate scleral buckling surgery (SB) for rhegmatogenous retinal detachment (RRD) in a single academic hospital, analyze incidence cystoid macular edema (CME) after SB using optical coherence tomography (OCT), and reveal factors associated with development CME. This was retrospective observational patients RRD who underwent from 2010 2020 hospital. anatomical initially achieved 267 288 eyes (92.7%), finally (100%). After excluding...

Abstract Even after idiopathic macular hole (MH) surgery and with successful closure of MH, aniseikonia is a common postoperative symptom. We investigated the correlation MH diameter, retinal displacement layer thicknesses in 41 eyes patients undergoing internal limiting membrane peeling. Aniseikonia was measured New Test. Retinal (RD%) defined as change distance between temporal margin optic papilla intersection vessels. Changes inner nuclear (INL%) outer (OR%) were calculated. improved...

Purpose: To investigate correlations of the optical coherence tomography–based epiretinal membrane (ERM) classification with metamorphopsia and tangential retinal displacement after ERM surgery. Methods: stage (stage 1–4) was defined as originally described. Metamorphopsia scores at baseline, 1 month, 3 months, 6 months surgery were measured M-CHARTS (Inami, Co, Tokyo). Tangential described previously. Eyes cysts, lamellar hole proliferation, or retinoschisis excluded. Results: One hundred...
