This 64 year-old male with MacTel2 had a visual acuity of 20/30 in each eye and was imaged with volume rendered OCTA with segmentation of the retinal cavitations from the structural OCT data. There are prominent right-angle veins in each eye. (A) The exit point of the right-angle vein from the substance of the retina in the right eye is at the nexus of a network of vessels, which appear to be drawn into a central focus. Retinal arterioles, venules, and small order vessels appear to be involved. The foveal avascular zone is distorted and appears to be pulled toward the temporal macula. There is a group of neighboring (and in the image, overlapping) foveal cavitations (cyan) that are on the temporal side of the foveal avascular zone. (B) Viewed from the choroidal side, the deeper penetrating vessels appear as yellow. This region corresponded to the area of late fluorescein staining. (C) More prominent traction on the vessels are evident in the left eye with pulling of the perifoveal vessels into an apex of a triangle (open arrow). (D) Viewed from the choroidal side the vessels deep to the deep vascular plexus are shown in yellow. The cystoid space in the left eye (cyan) has a complex outer boundary (From Spaide et al. Retina, 2017).
