Visual impairment, although not routinely assessed, is an important risk factor for falls and hip fracture in older people. Impaired vision is highly prevalent and commonly unreported in the elderly population particularly in women and those living in nursing homes. Measurement of visual functions such as visual acuity, contrast sensitivity and depth perception may identify older people at risk of falls and hip fracture. Visual loss in older people is correctable in most cases. Intervention strategies, for example, change of glasses or cataract extraction may have the potential of improving visual function and preventing falls in older people.
视力障碍虽然并非常规评估项目，但却是老年人跌倒和髋部骨折的重要风险因素。视力受损在老年人群中高度普遍，且通常未被报告，尤其是在女性以及居住在养老院的人群中。对视敏度、对比敏感度和深度感知等视觉功能进行测量，可能会识别出有跌倒和髋部骨折风险的老年人。大多数情况下，老年人的视力丧失是可以矫正的。干预策略，例如更换眼镜或白内障摘除术，可能有改善老年人视觉功能并预防跌倒的潜力。
