Manual segmentation of an OCTA scan of the right eye of an 8-year-old patient with Stage 2B Coats disease. The patient had a central subfoveal scar, necessitating manual segmentation of the layers on the OCTA B-scan (bottom of image). The red and green lines delineate the superficial capillary plexus, as manually adjusted to bypass the scar. The top image is the resultant en face optical coherence tomography angiography scan.
