As a major cause of vision loss, glaucoma may impair performance on many activities of daily living, such as reading, driving, and walking.1 In fact, because of the important role of vision in balance control and environment navigation, it is not surprising that glaucoma damage may affect gait and increase the risk of falls, a leading cause of injury-associated death in older people.2-4 However, the specific mechanisms associating glaucoma with falls or a decline in walking performance have not yet been fully elucidated, to my knowledge.
