Purpose.: To test the hypothesis that the intravascular oxygen response to light flicker is
abnormal in diabetes. Methods.: Ten eyes of normal rats and 10 eyes of rats made diabetic …

Purpose.: We investigated the response of retinal vessel diameters and oxygen saturation to
flicker light stimulation of neuronal activity in patients with diabetic retinopathy. Methods.: We …

purpose. To investigate oxygen tension (P o 2) changes in the retinal and choroidal
vasculatures in response to visual stimulation by light flicker. methods. A previously …

Purpose.: Luminance flicker stimulation of the photoreceptors is known to increase retinal
blood flow. Elevated blood velocity was determined using laser Doppler velocimetry, and …

Purpose: Light flicker has been shown to stimulate retinal neural activity, increase blood
flow, and alter inner retinal oxygen metabolism (MO 2) and delivery (DO 2). The purpose of …

Purpose.: Diabetic retinopathy is characterized by retinal vascular impairment resulting in
retinal hypoxia. The disease can be treated by retinal photocoagulation, but the mechanism …

Purpose: The retinal blood vessels provide a unique way to directly examine the human
microvasculature, which is frequently damaged in individuals with diabetes. Previous …

purpose. Animal studies have indicated that retinal oxygen consumption is greater in dark
than light. In this study, oxygen saturation is measured in retinal vessels of healthy humans …

Purpose: To mathematically model the temporal dynamic responses of retinal vessel
diameter (D), oxygen saturation (SO 2), and inner retinal oxygen extraction fraction (OEF) to …

Purpose.: To determine the retinal oxygen saturation trend with onset of diabetes and
increasing severity of diabetic retinopathy by comparing diabetic groups with and without …
