The retinal and cerebral microvasculatures share many morphological and physiological
properties. Assessment of the cerebral microvasculature requires highly specialized and …

There is a growing body of evidence suggesting that vascular dysfunction is related to
several prominent ophthalmic diseases, including glaucoma. The vast majority of studies …

Purpose To investigate changes in retinal vessel diameter and blood velocity in high myopia
using laser Doppler velocimetry. Methods Thirty-nine subjects (39 eyes) were enrolled in the …

Since vascular impairment has been hypothesized to play a role in several ocular diseases
including glaucoma, diabetic retinopathy and age-related macular degeneration, the non …

The objective of this study was to establish the baseline retinal hemodynamic characteristics
of stratified groups of diabetic patients at increasing risk for the development of diabetic …

Purpose Previous studies report that the response of retinal vessels to a decrease in oxygen
(hypoxia) is vasodilation, thus increasing blood flow. We aimed to characterize the changes …

Purpose To assess the repeatability of blood flow velocity index (BFVi) metrics obtained with
a recently Food and Drug Administration–cleared laser speckle contrast imaging device, the …

Key points Vascular reactivity, the response of the vessels to a vasoactive stimulus such as
hypoxia and hyperoxia, can be used to assess the vascular range of adjustment in which the …

Studies have shown that vascular impairment plays an important role in the etiology and
pathogenesis of various ocular diseases including glaucoma, age-related macular …

Background The purpose of this study was to test the reliability of vessel diameter
measurements with a newly developed retinal oximeter. Methods Twelve healthy individuals …
