Glaucoma Evaluation

What is glaucoma?

In a healthy eye, clear fluid is constantly being made behind the iris and leaving the eye through a microscopic drainage canal in the front of the eye. If this drainage channel becomes blocked, the pressure inside the eye goes up and often causes glaucoma damage to the optic nerve. This is the nerve that connects the eye to the brain so damage to it causes loss of vision.

Who is at risk?

While the causes of glaucoma are not completely known, we do know that risk factors for its development include a family history of glaucoma, race, and older age. Glaucoma may affect people of any age from newborns to the elderly but is more common in adults as they approach their senior years. African-Americans, Hispanics, and people with diabetes are also at increased risk of developing the disease.

The only sure way to diagnose glaucoma is with a complete eye exam. A glaucoma screening that only checks eye pressure is not enough to find glaucoma. One of the problems with glaucoma, especially open-angle glaucoma, is that there are typically no symptoms in the early stages. Many people who have the disease do not know they have it. This is why it is important, especially as you get older, to have regular medical eye exams by an Eye M.D.
