Early visual changes in diabetic patients with no retinopathy measured by color discrimination and electroretinography
Early visual changes caused by diabetes include color vision losses and an abnormal full-field electroretinogram. The purpose of this study was to evaluate color vision in type 2 diabetic patients with no clinically detectable retinopathy using an objective psychophysical color vision test, evaluate retinal function assessed by full-field electroretinography (ffERG), and verify the agreement am...
متن کاملA Decision Support System for Early-Stage Diabetic Retinopathy Lesions
Retina is a network layer containing light-sensitive cells. Diseases that occur in this layer, which performs the eyesight, threaten our eye-sight directly. Diabetic Retinopathy is one of the main complications of diabetes mellitus and it is the most significant factor contributing to blindness in the later stages of the disease. Therefore, early diagnosis is of great importance to prevent the ...
متن کاملDiabetic retinopathy is associated with early autonomic dysfunction assessed by exercise-related heart rate changes.
Diabetic retinopathy has been associated with cardiac autonomic dysfunction in both type 1 and type 2 diabetes mellitus (DM) patients. Heart rate (HR) changes during exercise testing indicate early alterations in autonomous tonus. The aim of the present study was to investigate the association of diabetic retinopathy with exercise-related HR changes. A cross-sectional study was performed on 72 ...
متن کاملLocal multifocal oscillatory potential abnormalities in diabetes and early diabetic retinopathy.
PURPOSE To study retinal dysfunction in diabetes and early nonproliferative diabetic retinopathy (NPDR) using a new method to analyze local multifocal electroretinogram oscillatory potentials (mfOPs). METHODS One eye of each of 26 normal subjects, 16 diabetic subjects without retinopathy (NoR), and 16 diabetic subjects with early NPDR was examined. Slow-flash multifocal electroretinograms (sf...
متن کاملRetinylamine Benefits Early Diabetic Retinopathy in Mice.
Recent evidence suggests an important role for outer retinal cells in the pathogenesis of diabetic retinopathy (DR). Here we investigated the effect of the visual cycle inhibitor retinylamine (Ret-NH2) on the development of early DR lesions. Wild-type (WT) C57BL/6J mice (male, 2 months old when diabetes was induced) were made diabetic with streptozotocin, and some were given Ret-NH2 once per we...
