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 …

Background Longstanding diabetes mellitus results in a disturbed microcirculation. A new
imaging oximeter was used to investigate the effect of this disturbance on retinal vessel …

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.: This study investigated the responses of retinal vessels to flickering light in
diabetic patients with various stages of diabetic retinopathy (DR). Methods.: This cross …

Background/aim: Stimulation of the retina with flickering light increases retinal arterial and
venous diameters in animals and humans, indicating a tight coupling between neural activity …

Aim Retinal oxygen metabolism is thought to be affected in diabetic retinopathy. The aim of
this study was to test whether retinal vessel oxygen saturation is different in patients with …

Purpose Diabetic retinopathy is characterized by morphological lesions in the retina
secondary to disturbances in retinal blood flow which may influence the supply of oxygen to …

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

Purpose.: A variety of studies have shown that flicker-induced vasodilatation is reduced in
patients with diabetes. It is, however, unclear whether reduced neural activity or abnormal …
