Glaucoma of all types is one of the most common cause of legal blindness in the United States.1
Open-angle glaucoma (OAG)
The most common type of glaucoma is open-angle glaucoma.
- OAG is more common in older people. The risk of glaucoma increases rapidly after a person reaches age 40. People age 70 and older are about 4 to 7 times more likely to develop glaucoma than people 40 to 50 years old.2
- OAG is 3 times more common among African Americans than in non-Hispanic whites.1
Closed-angle glaucoma (CAG)
It is estimated that closed-angle glaucoma accounts for about 10% of all glaucoma cases in the United States.3
- CAG is more common in farsighted people and in women. It is least common in whites.
- Acute closed-angle glaucoma is uncommon in African Americans.
- CAG is less common among Native Americans than whites, but it is more common among Canadian, Alaskan, and Greenland Inuit peoples and among people from East Asia or with East Asian ancestry.
Congenital glaucoma
Congenital glaucoma is rare.
