The purpose of screening is early diagnosis and treatment. Screening tests are usually administered to people without current symptoms, but who may be at high risk for certain diseases or conditions.
A comprehensive eye examination screens for cataracts. This examination should include:
Visual acuity test—This eye chart test measures how well you see at various distances.
Slit lamp exam—This examination of the eye uses a specialized microscope that magnifies the eye.
Tonometry—This standard test measures fluid pressure inside the eye; increased pressure may be a sign of glaucoma
Dilated eye exam—The doctor gives you special eye drops to widen your pupil, which allows better examination of the lens and the structures of the back of the eye.
Ask your doctor for guidelines specific to your individual situation. The American Academy of Ophthalmology recommends the following general screening guidelines for healthy adults with no risk factors for eye disease:
At least once between age 20-29
At least twice between age 30-39
Age 40-64: every 2 to 4 years
Age 65 and older: every 1 to 2 years
You should be screened more often, as directed by your doctor, or if you:
Have risk factors for cataracts, glaucoma, or other eye diseases
Have a personal or family history of eye disease
Have had a serious eye injury in the past
Had eye surgery in the past
Are taking a corticosteroid medication
Have diabetes, high blood pressure, or other chronic illness
: If you currently have eye symptoms, you should call your provider immediately for an evaluation. In case of an emergency, call for an ambulance immediately.
