Glaucoma Screening - Topic Overview
The American Academy of Ophthalmology recommends that all people be screened for glaucoma before the age of 40.1 But after reviewing all of the research, the U.S. Preventive Services Task Force (USPSTF) has not recommended for or against glaucoma screening for all adults.2 Still, it is especially important for people who are at increased risk for glaucoma to be tested every year. People at increased risk include those who:
- Are older than 65.
- Are African Americans (for open-angle glaucoma).
- Are East Asians and people with East Asian ancestry (for closed-angle glaucoma).
- Are farsighted (greater risk of developing closed-angle glaucoma).
- Have had an eye injury or eye surgery, such as cataract surgery.
- Have diabetes.
- Have high blood pressure (hypertension).
- Have been taking corticosteroid medicines.
- Have a family history of glaucoma.
Because people with glaucoma may have normal pressures in their eyes, measuring eye pressure (tonometry) should not be used as the only test for glaucoma. It needs to be combined with other tests before glaucoma can be diagnosed.
Night Vision Problems: Halos, Blurred Vision, and Night Blindness
Are you having problems with night vision? Millions of Americans do. Poor night vision may simply be an early sign of progressive cataracts.
