Normal functioning of the eye depends on a proper supply of blood to the retina. Light entering the eye passes through the cornea, the lens, and the vitreous body before reaching the retina, where it stimulates the nerves. If the retina contains too few or too many blood vessels – i.e., if it is under- or oversupplied with blood – a number of severe, often blinding eye diseases can develop.
