Glaucoma is a group of diseases that can damage the optic nerve.
There are often no symptoms or pain associated with the onset of disease. Left untreated, glaucoma can cause permanent vision losseven blindness.
Glaucoma can be detected through a dilated eye exam. A dilated eye exam allows an eye care professional to see inside the eye to check for signs of glaucoma and other vision problems.
While anyone can get glaucoma, the National Eye Institute (NEI) encourages those at higher risk to get a dilated eye exam every one to two years. Individuals at higher risk include African Americans over age 40; everyone over age 60, especially Mexican Americans; and people with a family history of glaucoma.
