Glaucoma
Glaucoma is a condition of 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. Glaucoma can cause partial vision loss, with blindness as a possible eventual outcome. Glaucoma affects an estimated 3 million Americans, with 120,000 blind due to the condition.
