Abstract
The retinal vasculature can be viewed directly and noninvasively, offering a unique and accessible window to study the health of the human microvasculature in vivo. The appearance of the retinal blood vessels is an important diagnostic indicator for much systemic pathology, including diabetes mellitus, hypertension, cardiovascular and cerebrovascular disease, and atherosclerosis [1–3]. There is mounting evidence supporting the notion that the retinal vasculature may provide a lifetime summary measure of genetic and environmental exposure, and may therefore act as a valuable risk marker for future systemic diseases [4]. Using its characteristics may provide early identification of people at risk due to diverse disease processes [5].
