Angle-closure glaucoma

Other Names:
Primary angle-closure glaucoma
Secondary angle-closure glaucoma
Narrow-angle glaucoma
Closed-angle glaucoma

Angle-closure glaucoma, also known as narrow-angle glaucoma, is caused by blocked drainage canals in the eye, resulting in a sudden rise of pressure in the eye. This is a much more rare form of glaucoma, which develops very quickly and demands immediate attention.


People who have farsightedness are at an increased risk for acute angle-closure glaucoma because their eyes are smaller, their anterior chambers are shallower, and their angles are narrower.

In the United States, fewer than 10% of glaucoma cases are due to angle-closure glaucoma. In Asia, angle-closure glaucoma is more common than open-angle glaucoma.

Certain races, i.e. Asians and Eskimos, have narrow angles and are more likely to develop angle-closure glaucoma than Caucasians. Angle-closure glaucoma among American Indians is lower than among Caucasians. In Caucasians, angle-closure glaucoma is three times higher in women than in men. In African Americans, men and women are affected equally.
