Adequate oxygen delivery to a tissue depends on sufficient oxygen content in arterial blood
and blood flow to the tissue. Oximetry is a technique for the assessment of blood …

Alzheimer's disease (AD) may manifest retinal changes preceding brain pathology. A
transversal case-control study utilized spectral-domain OCT angiography (SD-OCTA) and …

Introduction We propose a minimum data set framework for the acquisition and analysis of
retinal images for the development of retinal Alzheimer's disease (AD) biomarkers. Our goal …

Branching patterns are ubiquitous in nature; consequently, over the years many researchers
have tried to characterize the complexity of their structures. Due to their hierarchical nature …

Evidence is accumulating that cognitive function, and visual impairment may be related. In
this pilot study, we investigated whether multifractal dimension and lacunarity analyses …

The retinal neurovascular unit consists of blood vessel endothelial cells, pericytes, neurons,
astrocytes, and Müller cells that form the inner retinal blood barrier. A peripheral capillary …

Significance It has been hypothesized that abnormal microcirculation in the retina might
predict the risk of ischemic damages in the brain. Direct comparison between the retinal and …
