The example of optical coherence tomography angiography (OCTA) image in three groups. En face image (6 × 6 mm) of the corresponding layer of the superficial (A) and deep (B) capillary plexuses, and the area of the foveal avascular zone (FAZ) (C) was automatically calculated in Group I (0.445) (right eye, bilateral RB had a preserved eye with extramacular tumors). En face of the corresponding layer of the superficial (D) and deep (E) capillary plexuses, and the area of the foveal avascular zone (FAZ) (F) in Group II (0.224) (left eye, unilateral RB with a normal eye). En face of the corresponding layer of the superficial (G) and deep (H) capillary plexuses, and the area of the foveal avascular zone (FAZ) (I) in control Group (0.203) (left eye). Capillary density was calculated as percent of vessels per en face image for both plexuses. The mean superficial plexus capillary density did not demonstrate statistically significant difference in three groups. By contrast, mean deep plexus capillary density was significantly reduced in group I compared with controls
