简介：目的：评价青光眼患者的生存质量并探讨影响其生存质量的因素。方法：采用国家眼科研究所视功能问卷-25,对126例青光眼患者的生活质量进行评价。结果：青光眼患者的生存质量普遍下降,不同程度的视力损害明显影响着患者的生存质量得分（P〈0.01）。多因素逐步直线回归显示：生存质量的得分与年龄、经济收入、遵医行为有密切关系（P〈0.05）。结论：在保护青光眼患者视功能的同时,要重视其社会、心理等因素,给予其必要的健康教育和心理辅导,以期提高其生存质量。

简介：目的：比较白内障超声乳化吸除人工晶状体植入术后和小切口囊外门内障摘除人工品状体植入术后患者生存质量的变化。方法：分别于术前和术后1／4，1，3mo，观察I组108例单眼行白内障超声乳化吸除人工晶状体植入术后患者和II组94例单眼行小切口白内障囊外摘除人工晶状体植入的眼部情况，使用生存质量调杏量表记录分数。结果：术前生存质量总分数和各指标分数，术后1mo和3mo的生存质量总分数，I组和Ⅱ组比较差异均无显著意义（P〉0．05）。术后1／4mo生存质量总分数和各指标分数，I组高于Ⅱ组，两组比较差异有显著意义（P〈0．05）。结论：白内障超声乳化吸除人工品状体植入术患者的生存质量在短期内就得到明显提高。手术效果优于小切口囊外白内障摘除术。中期效果I组和Ⅱ组无明显差异，远期结果尚待进步深入探讨。
