These include changes in lowlight vision, color vision, binocularity (ability to focus on an object with both eyes), contrast sensitivity, accommodation (ability to change focus), and stereopsis (depth perception), as well as visual field loss (areas in the field of view in which objects cannot be seen). Impaired visual acuity refers to decreased clarity or sharpness of vision and is affected by a number of factors. Recommendation The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of screening for impaired visual acuity in older adults.

The evidence is lacking, and the balance of benefits and harms cannot be determined. Population Asymptomatic adults 65 years or older who present in primary care without known impaired visual acuity and are not seeking care for vision problems.Įvidence Assessment The USPSTF concludes that the evidence is insufficient to assess the balance of benefits and harms of screening for impaired visual acuity in asymptomatic older adults. Objective To update its 2016 recommendation, the US Preventive Services Task Force (USPSTF) commissioned a systematic review to evaluate the benefits and harms of screening for impaired visual acuity in older adults. Impaired visual acuity is consistently associated with decreased quality of life in older persons, including reduced ability to perform activities of daily living, work, and drive safely, as well as increased risk of falls and other unintentional injuries. The number of persons 60 years or older with impaired visual acuity (defined as best corrected visual acuity worse than 20/40 but better than 20/200) was estimated at 2.91 million in 2015, and the number who are blind (defined as best corrected visual acuity of 20/200 or worse) was estimated at 760 000. Importance Impairment of visual acuity is a serious public health problem in older adults.
