Glaucoma is a disease of the optic nerve that is often related to increased fluid pressure inside the eye. The increased pressure causes compression of the retina and the optic nerve, which can eventually lead to nerve damage. Without treatment, glaucoma can cause partial vision loss, with blindness as a possible eventual outcome.
