Blood supply to eye and optic nerve

An ophthalmic artery and a central retinal artery (an artery that branches off of the ophthalmic artery) provide blood to each eye. Similarly, ophthalmic veins (vortex veins) and a central retinal vein drain blood from the eye. These blood vessels enter and leave through the back of the eye.
