    Differentiating veins from arteries on optical coherence tomography angiography by identifying deep capillary plexus vortices

    Purpose To introduce a simple method for differentiating retinal veins from arteries on optical coherence tomography angiography (OCTA). Design Cross-sectional pilot study. Methods Four default en face slabs including color depth encoded, greyscale full-thickness retina, superficial plexus, and deep capillary plexus (DCP) from 9 3x3 mm and 9 6x6 mm OCTA scans were exported and aligned. Nine ophthalmologists with minimum OCTA experience from 2 eye institutions were instructed to classify labeled vessels as arteries or veins in 3 stages. Classification was performed based on graders’ own assessment at Stage 1. Graders were taught that a capillary-free zone was an anatomic ...
