Abstract
Visual impairment in the elderly may alter their life style and functional independence. Visual alterations may cause depression, falls and a reduction in social interaction, altering the quality of life. The control of body balance may be impaired in individuals with visual deficits. The objective of this study was to review the last 15 years of literature on the impact of visual alterations through feedback from the visual system, on functional performance, on postural control and on balance in the elderly. The assessment of visual acuity may not be sufficient to identify those individuals who are at risk of falling. Other measurements related to visual function, such as contrast, sensitivity and depth perception, are also important. Many problems related to impaired vision in the elderly are correctable or treatable, either by the use of reflective vision correction or by extraction of cataracts, thus improving both visual and motor functions.
