简介：目的分析老年人视力损害的眼病病因及心理影响。方法收集眼科门诊60岁以上老人850例,分三组：60-69岁,70-79岁,≥80岁。检查视力、眼科仪器检查、评估心理状况,对数据进行统计分析。结果各视力级别的总比例：≥5.0（5.46%）,较好视力4.5-4.9（60.62%）,低视力4.0-4.4（24.34%）,盲〈4.0（9.58%）。在年龄组间随年龄增高,较好视力的比例下降（66.45%,57.11%,38.23%）,低视力（25.33%,35.54%,47.27%）和盲（5.12%,7.24%,14.50%）的比率升高,差异有统计学意义（P〈0.05）。随视力级别下降,心理状况水平优的人数比例而降低（90.13%,82.31%,34.24%,2.10%）,状况水平差的比例而升高（1.73%,5.46%,45.35%,85.44%）,差异有统计学意义（P〈0.05）。低视力和盲的主要眼病构成比：白内障52.33%,屈光不正20.11%,老年性黄斑变性14.32%,糖尿病视网膜病变7.02%,眼底静脉阻塞3.10%。结论老年人视力损害眼病前五位是白内障,屈光不正,老年性黄斑变性,糖尿病视网膜病变,眼底静脉阻塞。老年人低视力和盲的比例高,视力损害者不良心理状况比例高,视力损害对老年人心理状况的影响值得重视。

简介：过敏性眼表疾病是眼科门诊常见的眼部炎症。由于眼表暴露在各种各样的过敏原下,使眼部易导致过敏性反应。过敏性眼部疾病最特征的表现是眼部的瘙痒感,表现为双侧性,临床表现因人而异。
