Fig. 16 Retinal termination at the posterior edge of an ora bay shows aging changes of outer plexiform layer cysts (1, 2) and a reticular cyst (asterisk) in the inner plexiform layer, imposed on the characteristic fusion of layers and malformed photoreceptors (arrow). The disappearance of the endothelium and the intramural pericytes of the superficial capillary (open arrow) is characteristic of the obliterated peripheral retinal capillaries, which are marked by their basement membranes.
