The most important causes of central and peripheral visual impairment in older adults include glaucoma, cataract, diabetic retinopathy, and macular degeneration. Most of these conditions can be controlled or, as in the case of cataracts, vision can be restored to a significant level to improve the
quality of life. Glaucoma and macular degeneration progression may be slowed with proper treatment. Regular eye examinations for older adults can detect early signs of ocular abnormalities and ensure that proper treatment is initiated. Generally, adults older than 40 years should have a complete examination at least every 3 years. After age 65, the examination should be at 1- to 2-year intervals.
