Summary

The management of ocular health in the rapidly aging United States population presents an ever expanding challenge to primary care providers, geriatricians and ophthalmologists alike. The United States defines visual impairment as vision with corrective lenses of worse than 20/40 but better than 20/200 in the better-seeing eye. Vision worse than 20/200 with corrective lens is the definition of legal blindness. Approximately 4.1 million Americans are visually impaired, and 1.2 million Americans 40 years and older are legally blind according to the most recent census. In a population-based study, the rate of visual impairment in individuals 80 years and older was 15 to 30 times greater than individuals 40-50 years old. In addition, because many eye diseases can be insidious in onset, the American Academy of Ophthalmology recommends a comprehensive eye exam every one to two years in otherwise healthy individuals over age 65. Preventing blindness is an important factor in assisting the elderly to function autonomously and lead productive lives. Blinding disorders can cause significant personal, familial, and societal burdens.
