High pressure in the eyes. OAG is
often linked with higher-than-normal pressure in the eyes (intraocular pressure, or IOP). Not all people with OAG have high IOP. But this is one treatable risk factor that doctors look for.
Age. The risk for glaucoma increases rapidly after
Race. Blacks are
more likely than whites to have glaucoma.
Family history of glaucoma. You're at risk for OAG if a relative has primary OAG, which is OAG that's not caused by another condition.
Prior loss of vision in one eye from glaucoma. Damage in one eye from glaucoma is linked with a higher risk
of future damage in the other eye.
Diabetes. People who have diabetes tend to have higher
pressure in their eyes than those who don't have the disease. People who have diabetes are
also at risk for a type of secondary glaucoma where new blood vessels grow into
and block the drainage angle of the eye.
Race. People from East Asia or with East Asian
ancestry, as well as Inuit peoples, are more
likely than other people to develop CAG.1
Age. People over age 40 are at increased risk for
Being female. Older women are more likely than older men to
Farsightedness. People who are farsighted are more
likely to develop this condition. That's because their eyes are smaller and the
drainage angles of the eyes tend to be narrower, which allows them to become
blocked more easily.
Family history. People who have a family history of
CAG are more likely to develop the condition.
Having CAG in one eye. This increases the risk of getting the condition
in the other eye. About half of the people who have had acute closed-angle
glaucoma in one eye develop CAG in the second eye within 5
Infection in the mother during pregnancy. Babies
born to mothers who have certain viral infections such as
rubella during pregnancy are more likely to have the condition.
Family history. A small number of infants with
congenital glaucoma inherit the condition.
