Abstract

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. © 2018 Human Kinetics, Inc.
