| The tip of the optic nerve, seen inside the eye is called the optic disc. The major blood vessels to the retina (Central retinal
artery and vein) come out of the optic disc and then branch out. These blood vessels are the main source of nutrients and oxygen
to the retina, although a segment of the retina receives its nutrients from the layer below it (the choroid). The part of the retina
responsible for a persons best and central vision is called the macula. In the very center of the macula is the fovea which is
responsible for ones most fine central vision. |
