Are You at Risk For Glaucoma?
Everyone is at risk for glaucoma. However, certain groups are at higher risk than others.
People at high risk for glaucoma should get a complete eye exam, including eye dilation, every one or two years.
The following are groups at higher risk for developing glaucoma.
African-Americans
Glaucoma is the leading cause of blindness among African-Americans. It is six to eight times more common in African-Americans than in Caucasians.

People Over 60
Glaucoma is much more common among older people. You are six times more likely to get glaucoma if you are over 60 years old.
Family Members with Glaucoma
The most common type of glaucoma, primary open angle glaucoma, is hereditary. If members of your immediate family have glaucoma, you are at a much higher risk than the rest of the population.
Family history increases risk of glaucoma four to nine times.
Hispanics in Older Age Groups
Recent studies indicate that the risk for Hispanic populations is greater than those of predominantly European ancestry, and that the risk increases among Hispanics over age 60.
Asians
People of Asian descent appear to be at some risk for angle closure glaucoma. Angle closure glaucoma accounts for less than 10% of all diagnosed cases of glaucoma. Otherwise there is no known increased risk in Asian populations.
Steroid Users
Some evidence links steroid use to glaucoma. A study reported in the Journal of American Medical Association, March 5, 1997, demonstrated a 40% increase in the incidence of ocular hypertension and open angle glaucoma in adults who require approximately 14 to 35 puffs of steroid inhaler to control asthma. This is a very high dose, only required in cases of severe asthma.
Eye Injury
Injury to the eye may cause secondary open angle glaucoma. This type of glaucoma can occur immediately after the injury or years later.
Blunt injuries that “bruise” the eye (called blunt trauma) or injuries that penetrate the eye can damage the eye’s drainage system, leading to traumatic glaucoma.
The most common cause is sports-related injuries such as baseball or boxing.

Other Risk Factors
Other possible risk factors include:
- high myopia (nearsightedness)
- diabetes
- hypertension
- Central corneal thickness less than .5 mm.
