The retina receives blood from two sources, the choroidal capillaries and the central retinal artery. The retinal and choroidal blood vessel pattern is unique to every person. The branches of the central artery and vein, for instance, diverge from the optic disc in a distinctive pattern that varies considerably across individuals. These retinal blood vessels are readily visible on a regular fundus photograph taken with visible light, whereas the choroidal blood vessels, forming a matting behind the retina, become visible when observed with near-infrared illumination.
