Does glaucoma always lead to blindness?
No. Although glaucoma is a leading cause of blindness in the United States, it can be controlled and vision maintained if it is caught early. Because the disease usually produces no symptoms until it has begun to steal a person’s sight, many of those who have it don’t know it. In fact, the Glaucoma Research Foundation estimates that over four million Americans have glaucoma and half of them don’t know it. That’s why comprehensive eye examinations are recommended at least every two years for those at increased risk for the disease.
