Common Eye Conditions: Glaucoma

Glaucoma is an eye disease in which the passages that allow fluid to drain out of the eye become clogged. This results in the amount of fluid in the eye building up and causing increased pressure inside the eye. This increased pressure damages the optic nerve. The optic nerve is the main carrier of vision information to the brain. Damage to it results in less information sent to the brain and a loss of vision.

The exact cause of glaucoma is not known and, it cannot currently be prevented. It is one of the leading causes of blindness in the U.S. If detected at an early stage and treated promptly, glaucoma can usually be controlled with little or no further vision loss. That's why regular optometric examinations are so important. People of all ages can develop glaucoma, but it most frequently occurs in people:

Who are over age 40
Who have a family history of glaucoma
Who are very nearsighted
Who are diabetic
Who are black

Primary Open Angle Glaucoma develops gradually and painlessly, without warning signs or symptoms. This type of glaucoma is more common among African Americans and Asian males than Caucasians. It can cause damage and lead to blindness more quickly in blacks, making regular eye examinations, including tests for glaucoma particularly important for blacks over age 35.

Acute Angle-Closure Glaucoma may be accompanied by

Blurred vision
A loss of side vision
Appearance of colored rings around lights
Pain or redness in the eyes

Glaucoma can usually be treated effectively by using eye drops. In some cases surgery may be necessary. Unfortunately, any loss of vision from glaucoma cannot usually be restored. Early detection, prompt treatment and regular monitoring can enable you to continue living with normal eyesight.
