Abstract
Differential artery-vein analysis is valuable for early detection of diabetic retinopathy (DR) and other eye diseases. As a new optical coherence tomography (OCT) imaging modality, emerging OCT angiography (OCTA) provides capillary level resolution for accurate examination of retinal vasculatures. However, differential artery-vein analysis in OCTA, particularly for macular region in which blood vessels are small, is challenging. In coordination with an automatic vessel tracking algorithm, we report here the feasibility of using near infrared OCT oximetry to guide artery-vein classification in OCTA of macular region.
