Understanding which aspects of vision are related to falls is important. We examine the associations between tests of balance, mobility, fear of falling (FES-1) and aspects of vision in 72 adults aged 70+. Balance and mobility were examined using the One Legged Stance test (OLST), the Sit to Stand test (STST) and the 5 Meter Walking test (5MWT). Visual measures included visual acuity (VA), contrast sensitivity, stereoacuity, binocular vision (BV) measurements, Useful field of View (UFV) and Attended Field of View (AFOV). Reduced performance on the OLST and the STST was significantly correlated with abnormal BV and poorer intermediate VA. Poorer function on the 5MWT and the FES-I was also predicted by poor intermediate VA and poorer performance on the OLST, STST and the 5MWT was associated with UFV errors. The results are of high importance as many BV disorders are treatable and visual attention is trainable.
了解视力的哪些方面与跌倒有关很重要。我们研究了72名70岁及以上成年人的平衡测试、活动能力测试、跌倒恐惧（FES-1）与视力各方面之间的关联。使用单腿站立测试（OLST）、坐立测试（STST）和5米步行测试（5MWT）来评估平衡和活动能力。视觉测量包括视力（VA）、对比敏感度、立体视锐度、双眼视觉（BV）测量、有用视野（UFV）和注视视野（AFOV）。OLST和STST表现下降与异常BV和较差的中距离视力显著相关。中距离视力差以及OLST表现较差也预示着5MWT和FES-I功能较差，5MWT表现较差与UFV误差有关。这些结果非常重要，因为许多BV疾病是可治疗的，而且视觉注意力是可训练的。
