Glaucoma is a group of diseases that damage the eye’s optic nerve.
Fluid pressure in the eye builds up and causes damage to the optic nerve fibers over time.
Glaucoma can cause blindness if it is left untreated. Only about half of the estimated three million Americans who have glaucoma are even aware that they have the condition. Glaucoma develops with few, if any, early symptoms and progresses slowly. In this way, glaucoma can steal your sight very gradually. Fortunately, early detection and treatment (with glaucoma eye drops, glaucoma surgery or both) can help preserve your vision.
