Glaucoma

Because glaucoma develops slowly, many people can have the disease without being aware of it until they have suffered irreversible damage to their vision. Initially, exfoliation glaucoma causes no symptoms. Your central vision remains normal and there is no pain.

The main sign of glaucoma is a gradual loss of peripheral vision in one or both eyes. Left untreated, your field of vision can gradually narrow until it seems that you are looking through a tunnel. Be sure to see an eye doctor if you are not seeing objects that are off to the side, even though you can clearly see things straight in front of you. Other possible symptoms include:

• Trouble adjusting to seeing in a dark room
• Difficulty focusing
• Distorted lines and edges that seem wavy
