Abstract

The purpose of this study is to use optical coherence tomography (OCT) to characterize the reflectance profiles of retinal blood vessels and to use these features for artery-vein classification in OCT angiography (OCTA). The retinal arteries and veins show unique features in the depth-resolved OCT. Both the upper and lower side of the retinal arteries have hyperreflective boundaries. However, retinal veins reveal only hyper-reflective boundary at the upper side. In both small and large arteries, relatively uniform lumen intensity was observed. On the other hand, the vein lumen intensity was dependent on the vessel size; the bottom half of the lumen of small veins show a hyper-reflective zone while the bottom half of the lumen of big veins a hypo-reflective zone.
