Central retinal artery
The central retinal artery , also called the central artery of the eye, is actually an arteriole . It arises from the ophthalmic artery , then runs in the optic nerve (nervus opticus) to its papilla ( blind spot ), where it usually divides into four branches. It is an end artery and is responsible for supplying the inner layers of the retina with oxygen and nutrients. Their closure can lead to what is known as amaurosis fugax . The outer layers of the retina (especially the photoreceptors) are supplied by the blood vessel system of the choroid (choroid).
The arteria hyaloidea is a terminal branch of the arteria centralis retinae, which supplies the developing lens with nutrients during the embryonic development and which regresses before birth .
