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.: 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 …

In the retina, blood flow and neural activity are tightly coupled. Stimulation of the retina with
flickering light is accompanied by an increase in blood flow. The current study seeks to …

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 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: Malfunction of retinal blood flow or oxygenation is believed to be involved in
various diseases. Among them are retinal vessel occlusions, diabetic retinopathy and …

It has been shown that diffuse luminance flicker increases optic nerve head blood flow. The
current study has been performed to quantify changes in retinal blood flow during flicker …

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 …

Background Retinal vessel oxygenation saturation measurements have been the focus of
much attention in recent years as a potential diagnostic parameter in a number of ocular and …
