Open Angle Glaucoma

Back

In open-angle glaucoma, the angle in your eye where the iris meets the cornea is as wide and open as it should be, but the eye's drainage canals become clogged over time, causing an increase in internal eye pressure and subsequent damage to the optic nerve.

SYMPTOMS

Promptly go to an emergency room or an eye doctor's (ophthalmologist's) office if you experience some of the symptoms of acute angle-closure glaucoma, such as severe headache, eye pain and blurred vision.

CAUSES

Open-angle glaucoma is the most common form of the disease. The drainage angle formed by the cornea and iris remains open, but the trabecular meshwork is partially blocked. This causes pressure in the eye to gradually increase. This pressure damages the optic nerve.
