JAMA PATIENT PAGE. Screening for Impaired Visual Acuity in Older Adults.

What Is Impaired Visual Acuity? Visual acuity refers to how sharp or clear a person’s vision is. Impaired visual acuity refers to vision that is blurry, distorted, or otherwise not normal. Common causes of impaired visual acuity include refractive error (nearsightedness or farsightedness), cataracts, glaucoma, macular degeneration (loss of the center of the field of vision), and presbyopia (farsightedness that occurs with aging). Vision impairment due to cataracts, presbyopia, and agerelated macular degeneration is common in older adults. The March 1, 2016, issue of JAMA contains the updated USPSTF recommendations on screening for impaired visual acuity in older adults.
