Low vision: physician screening helps to improve patient function

Low vision is a common problem of older patients. As a primary care practitioner, you are not expected to treat most ocular problems, but you can play an important role by identifying patients with visual impairment. Familiarize yourself with the normal visual changes that occur with aging as well as the more common age-related ocular diseases, including glaucoma, cataracts, age-related macular degeneration, and diabetic retinopathy. You can identify patients with visual problems with a careful history and basic in-office tests of visual acuity. Refer patients found to have visual impairment to an eye care specialist for further evaluation.
