【摘要】 目的 调查458例≥80岁老年人的视力状况并分析其影响因素。 方法 常规检查≥80岁老人日常生活视力及眼部情况，对合作者验光矫正屈光不正，对疑似眼病采用相应的辅助检查；统计老年人视力并比较验光矫正前后的视力；分析影响视力及致盲和低视力的原因。 结果 ≥80岁老年人的日常生活视力平均057±044，盲和低视力患病率分别为39%和55%；矫正屈光不正后平均视力072±043，较验光前提高，差异有显著性；≥80岁老人平均患有2种眼病，最常见眼病是白内障，严重影响视力的眼病主要是老年性黄斑病变，其次为青光眼和各种类型的视神经萎缩。 结论 ≥80岁老人视力下降既有眼病因素，也有屈光不正和生理老化因素。为改善老年人的视力，除积极治疗相关眼病外，还应重视屈光不正的矫正。【主题词】 屈光不正； 视力，低； 盲； 老年人
