Glaucoma (Angle Closure Type)

Overview

This disorder damages the optic nerve at the rear of the eye, causing rapid loss of vision. It can strike suddenly and progress quickly.

Problem Develops

Glaucoma is commonly linked to a buildup of fluid pressure inside the eyeball. Fluid normally drains out of the trabecular meshwork, or "angle" - the area at the outer edge of the iris.

Pressure Builds

An eye's angle may be abnormally narrow. Some people are born with a thickened or bulging iris or an unusually shallow area above the iris. A change in fluid pressure can suddenly seal the angle shut, causing pressure in the eye to rapidly build.

Optic Nerve Affected

This pressure pushes harmfully against the optic nerve.

Vision Damaged

The pressure causes the erosion of the optic nerve, which permanently damages vision.

Symptoms

Narrow angle glaucoma can strike without warning and progress rapidly, causing severe eye pain, nausea, a clouding of the corneas, halos around lights and decreased vision. It can cause total blindness in as little as 3 to 5 days.

Treatment

Narrow angle glaucoma is a medical emergency that requires immediate medical treatment. Regular checkups can help identify those at risk for the disease. Treatment options may include prescription eye drops, surgery or a combination of the two.
