Glaucoma is a group of serious eye diseases that can cause permanent vision loss and blindness. It is caused when fluid doesn’t drain from the eye properly and the pressure build-ups in the eye.
More than 2.7 million Americans over age 40 have glaucoma and about half do not know they have it. The National Eye Institute predicts this number to increase to 4.2 million in the next 15 years. There are currently 120,000 Americans who have become blind because of glaucoma.
Glaucoma does not usually have signs or symptoms until vision loss has occurred. A person may lose up to 40 percent of their vision before noticing the change. The vision loss usually begins around the edges of vision or peripheral vision.
