General physicians have an essential role in preventing vision loss in older people. However, most vision-threatening eye disorders are initially asymptomatic and often go underdiagnosed. Therefore screening, early detection, and timely intervention are important in their management. The most common cause of visual impairment is uncorrected or undercorrected refractive error, followed by cataract, age-related macular degeneration, glaucoma, and diabetic retinopathy. Spectacles and cataract surgery can successfully restore sight for uncorrected refractive error and cataract, respectively. Visual impairment as a result of age-related macular degeneration, glaucoma, and diabetic retinopathy can be prevented with appropriate treatment if they are identified early enough. This chapter provides an overview of common age-related eye disease and visual impairment.
