Glaucoma affects a wide spectrum of daily essential activities in older adults. This study examined whether older adults with moderate and advanced stages of glaucoma exhibit differences in visuomotor task performance compared with age- and gender-matched ophthalmologically healthy control subjects and estimated the effects of physical activity (PA) levels, age, and severity of visual impairment on patients' visuomotor task performance. Sixty older adults with moderate glaucoma, advanced glaucoma, and normal sight participated in the study. Visuomotor processing was assessed using laboratory-based simple and complex visuomotor reaction tasks. Monocular Humphrey Visual Field and binocular Humphrey Esterman Visual Field tests were used to estimate visual field defect severity. The International Physical Activity Questionnaire was used to assess PA levels. Participants with glaucoma had poorer scores in visuomotor tasks compared to participants with normal sight. Glaucoma patients' PA levels, age, and binocular visual field defect explained 54% of the variation in complex reaction time. Low PA levels were identified as a risk factor for visuomotor processing decline. Compensatory mechanisms to improve the efficiency of visual field scanning in patients with more severe visual field defects may exist.
青光眼影响老年人广泛的日常基本活动。本研究旨在探讨中晚期青光眼患者与年龄和性别匹配的眼科健康对照组相比，在视动任务表现上是否存在差异，并评估身体活动 (PA) 水平、年龄和视力损害严重程度对视动任务表现的影响。共有 60 名中晚期青光眼、晚期青光眼和视力正常的老年人参与了研究。视动加工通过基于实验室的简单和复杂视动反应任务进行评估。单眼 Humphrey 视野和双眼 Humphrey Esterman 视野测试用于估计视野缺损严重程度。国际体力活动问卷用于评估 PA 水平。与视力正常的参与者相比，青光眼患者在视动任务中的得分较低。青光眼患者的 PA 水平、年龄和双眼视野缺损解释了复杂反应时间变化的 54%。低 PA 水平被认为是视动加工下降的危险因素。可能存在补偿机制，以提高严重视野缺损患者的视野扫描效率。
