Glaucoma is a group of eye diseases that can lead to vision loss and blindness. It occurs more often in adults over 60, in African Americans over 40, and in people with a family history of the disease. In the early stages, glaucoma has no warning signs, but if left untreated, changes in vision eventually become noticeable. If you are at risk for glaucoma, there are things you can do to protect your vision.
