Glaucoma (Open-Angle Type)

Overview

This disorder damages the optic nerve at the rear of the eye, causing loss of vision. It can progress so gradually that the person doesn't notice until significant damage has occurred.

Anatomy

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

If the eye's drainage system becomes clogged or damaged, fluid pressure builds inside the eye. It pushes harmfully against the optic nerve.

Vision Damaged

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

Symptoms

There are no signs of a problem during the early stages of the disease. But as it progresses, the person may notice mild aching of the eyes, halos around lights, decreased night vision and loss of peripheral vision. If left untreated, this will progress to tunnel vision and then blindness.

Treatment

Glaucoma should be treated as soon as it is diagnosed to prevent further loss of vision. Regular checkups can help identify the disease in its early stages. Treatment options may include prescription eye drops, surgery or a combination of the two.
