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 …

Purpose.: To correlate retinal function with vascular response to flicker light in normotensive
patients with diabetes without diabetic retinopathy (DR). Methods.: Twenty-eight …

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 …

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. Various studies have shown that retinal vessels in patients with diabetes mellitus
have a reduced capacity to adapt to changes in perfusion pressure and to stimulation with …

Background Diabetic retinopathy is accompanied with changes in the autoregulation of
retinal blood flow secondary to changes in the systemic blood pressure and the retinal …

AIMS: Investigation of retinal vasodilation under flickering light is considered a dynamic
analysis in contrast to the static analysis of retinal vessel equivalents (mean retinal vessel …

Flickering light stimulation of retinal photoreceptors induces retinal vessel dilation in
humans. In the present study the effect of high blood glucose levels on this neuro-vascular …

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 …

Purpose.: Subtle changes in retinal vascular caliber have been shown to predict diabetic
retinopathy and other diabetic complications. This study was undertaken to investigate …
