目的:探讨张家界市贫困白内障患者防盲术后低视力的影响因素。方法:统计2009-01/2010-12我市进行防盲手术的贫困白内障患者临床资料。650例患者以性别、年龄、文化程度、是否吸烟喝酒、相关疾病、核的硬度、术中并发症、术后并发症8个临床观察因素作为自变量(X),低视力作为因变量,对术后3d及术后3mo进行非条件Logistic回归分析,研究防盲术后低视力的影响因素。结果:对变量进行非条件Logistic回归分析:术后3d统计,χ2=16.325,P=0.000,筛选出年龄(P=0.028)、相关疾病(P=0.002)、术中并发症(P=0.015)、术后并发症(P=0.008)是影响低视力的危险因素。术后3mo统计,χ2=23.012,P=0.000,筛选出年龄(P=0.016)、相关疾病(P=0.001)是影响低视力的危险因素。结论:年龄、相关疾病、术中并发症、术后并发症是影响防盲术后早期低视力的危险因素,长期效果来看防盲术后低视力主要和基础眼病以及年龄有关。

AIM:To explore the factors of low vision after blindness prevention of poor cataract patients in Zhangjiajie.METHODS:The clinical data of poor cataract patients having surgery of prevention of blindness from January 2009 to December 2010 in our hospital were collected statistically.There were 650 cases.Eight clinical observation factors:gender,age,educational level,smoking and alcohol consumption,associated diseases,nuclear hardness,intraoperative complications and postoperative complications as independent variables(X),and low vision as the dependent variable were analysed with non-conditional Logistic regression analysis to study the factors of low vision after blindness prevention in 3 days and 3 months.RESULTS:The variables were analysed by the the non-conditional Logistic regression.The age(P=0.028),injury-related diseases(P=0.002),intraoperative complications(P=0.015),postoperative complications(P=0.008) were the risk factors of low vision in 3 days’ statistics.And the age(P=0.016),injury-related diseases(P=0.001),were the risk factors of low vision in 3 months’ statistics.CONCLUSION:The age,related diseases,intraoperative complications,postoperative complications are the risk factors of low vision in the surgery of blindness prevention in early postoperative stage,and it is related to the original ocular diseases and advanced age in the long-term.
