Glaucoma is a group of diseases that damage the eye’s optic nerve and can result in vision loss and blindness. However, with early detection and treatment, you can often protect your eyes against serious vision loss. Several large studies have shown that eye pressure is a major risk factor for optic nerve damage, yet it can develop without increased eye pressure.
The most common type of glaucoma is open-angle. At first, open-angle has no symptoms. It causes no pain, vision stays normal, and it can develop in one or both eyes. Without treatment, people with the condition will slowly lose their peripheral (side) vision. They seem to be looking through a tunnel. Over time, straight-ahead (central) vision may decrease until no vision remains. Learn more about glaucoma symptoms here.
Age, race, family history, and medical history are all factors that can increase your risk. However, anyone can develop it. Some people, listed below, are at higher risk than others:
