What is glaucoma?

Glaucoma is frequently called the “sneak thief of sight,” because there are often no symptoms before severe vision loss occurs. This is the leading cause of blindness in the United States. An estimated 1 out of 50 adults are affected by this disease. Loss of sight from glaucoma is preventable with early detection and treatment by your optometrist or ophthalmologist. Glaucoma is a series of diseases of the optic nerve. The optic nerve is the messenger between the eyes and the brain. When it becomes damaged, vision is impaired.
