Optical coherence tomography guided artery-vein classification in retinal OCT angiography of macular region

摘要

Differential artery-vein analysis is valuable for early detection of diabetic retinopathy (DR) and other eye diseases. As anew optical coherence tomography (OCT) imaging modality, emerging OCT angiography (OCTA) provides capillarylevel 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 vesseltracking algorithm, we report here the feasibility of using near infrared OCT oximetry to guide artery-vein classificationin OCTA of macular region.
