方法：纳入96例年龄相关性白内障术前患者作为受试者，使用综合性视觉功能指数(visual-functioning index，VF-7)问卷法评估受试者的综合性视觉功能。根据其结果进行分组，比较组间的跌倒影响因素差异性，包括视力、平衡功能、移动功能、认知及抑郁状态、对跌倒的担心等。

结果：其中VF-7得分较低组的受试者，其年龄通常较大，有抑郁倾向，以及更担心跌倒； 得分较低组的受试者视力、平衡功能和移动功能也较差。

结论：不同水平的综合性视觉功能指数的年龄相关性白内障老年患者，其跌倒影响因素，包括视力、平衡功能、移动功能之间有显著的差异。综合性视觉功能指数作为一种简单方便的自评检查方式，可以用作对年龄相关性白内障患者的跌倒风险监测。

METHODS:Ninety-six patients with age-related cataract were interviewed using a seven-item visual function questionnaire(VF-7), then classified into poor, moderate, or good visual function group. The differences of the three groups on visual acuity, balance and mobility function, cognition, depressive symptoms, self-reported fear of falling were analyzed.

RESULTS:The patients in poor visual function group had older age, tendency to depression, was more afraid of falling, compared with groups with higher score in VF-7, and they had worse visual acuity, performed worse on all balance and mobility tests.

CONCLUSION:Poor visual function is related to worse visual acuity, weaker balance and mobility performance in patients with age-related cataract. The VF-7, as a simple and convenient self-reported method, can be used as a falling risk monitoring in patients with age-related cataract.
