The retinal vasculature allows direct noninvasive visualization of the body's
mircrovasculature. Because the retina and other end organs (brain and kidney) share similar …

This paper presents a novel three-stage blood vessel segmentation algorithm using fundus
photographs. In the first stage, the green plane of a fundus image is preprocessed to extract …

This paper presents a novel unsupervised iterative blood vessel segmentation algorithm
using fundus images. First, a vessel enhanced image is generated by tophat reconstruction …

Endothelial dysfunction is a key pathogenic mechanism of CVD. The retinal microvascular
network offers a unique, non‐invasive window to study endothelial function. Recently …

Diabetes affects the structure of the blood vessel walls. Since the blood vessel walls are
made of birefringent organized tissue, any change or damage to this organization can be …

Retinal vessels are similar to cerebral vessels in their structure and function. Moderately low
oscillation frequencies of around 0.1 Hz have been reported as the driving force for …

Cerebral microcirculation is critical for the preservation of brain health, and vascular
impairment is associated with age-related neurodegenerative diseases. Because the retina …

Purpose: The purpose of this study was to analyze factors determining retinal arterial and
venous responses to stimulation with diffuse luminance flicker in healthy subjects. Methods …

Reliable assessment of endothelial function is important for the diagnosis, risk prediction
and treatment-monitoring in cardiovascular disease. Numerous techniques exist such as …

Blood vessel walls are made of organized fibrous tissue with intrinsic birefringence. Even in
its very early stages, hypertension can change the structure of a blood vessel wall. In this …
