These are the optic nerves of a patient with glaucoma. There is very little rim tissue and large cupping in the middle. Glaucoma occurs primarily when high pressure in the eye pinches off the blood supply to nerve tissue, causing permanent damage to that tissue and stealing the vision slowly until complete blindness occurs.
