Correlation between Visual Acuity and Optical Coherence Tomography-Measured Retinal Thickness in Diabetic Macular Edema
Background and Objective: Diabetic macular edema (DME) is one of the common complications of diabetes which significantly accounts for preventable visual impairment and blindness. Central macular thickness (CMT) is a feature found in DME patients. This study aims to determine the relationship between optical coherence tomography (OCT)-measured CMT and visual acuity (VA) in patients with DME bef...
متن کاملThe Relation between Visual Acuity and Illumination
1. Visual acuity varies in a definite manner with the illumination. At low intensities visual acuity increases slowly in proportion to log I; at higher intensities it increases nearly ten times more rapidly in relation to log I; at the highest illuminations it remains constant regardless of the changes in log I. 2. These variations in visual acuity measure the variations in the resolving power ...
متن کاملCorrelation between Fluorescein Angiographic Findings and Visual Acuity in Behçet Retinal Vasculitis
PURPOSE To identify significant fluorescein angiographic (FA) characteristics associated with visual acuity (VA) in Behçet retinal vasculitis. MATERIALS AND METHODS Retrospective review of 86 eyes of 48 patients (age: 35.6±10.2 years) with Behçet retinal vasculitis were performed. VA and FA findings as well as correlation between them were assessed. RESULTS The mean initial VA of eyes with ...
متن کاملCorrelation between Uncorrected Visual Acuity and Macular Distortion in Idiopathic Epiretinal Membrane Patients
PURPOSE To evaluate the association between degree of retinal abnormalities and uncorrected visual acuity (UCVA) in idiopathic epiretinal membrane (ERM) patients with a small amount of refractive error. METHODS We retrospectively reviewed 49 eyes (37 patients) of idiopathic ERM patients. We investigated the association between visual acuity and macular status (central macular thickness [CMT],...
متن کاملCorrelation between peripapillary macular fiber layer thickness and visual acuity in patients with open-angle glaucoma
PURPOSE To determine whether the best-corrected visual acuity (BCVA) is significantly correlated with the retinal nerve fiber layer thickness (RNFLT) in the different peripapillary areas in eyes with open-angle glaucoma (OAG). PATIENTS AND METHODS Two hundred twenty-nine eyes of 159 patients with OAG were studied. The overall RNFLT and the RNFLT in the superior (S), temporal (T), inferior (I)...
