Epidemiological survey on incidence of cataract in persons of 50 years or over in a resident district

目的 调查河南省商丘市梁园区50岁及以上人群中白内障患病率、白内障手术情况、手术覆盖率和白内障致盲率.方法 采用整群随机抽样方法.2008年9月至2008年12月在该区对50岁及以上5010例进行眼科检查,包括评价晶状体浑浊程度和白内障手术情况.应用多元逻辑回归分析受检者的年龄、性别和受教育程度、白内障患病率、白内障手术覆盖率.结果 在5010例受检者中,发现白内障1158例,患病率为23.11％.高龄、女性人群白内障患病率明显增高,差异均有统计学意义（P＜0.01）.在施行白内障手术的83例（96眼）中,采用现代白内障囊外摘出术联合人工晶状体（IOL）植入术49眼（51.04％）、采用晶状体超声乳化联合IOL植入术5眼（5.21％）,IOL植入率为56.25％.结论 白内障是河南省梁园区50岁及以上人群的主要致盲性眼病.该区白内障手术覆盖率较低,IOL植入率偏低.

Objective To investigate the prevalence of cataract,cataract surgery,cataract surgical coverage and the rate of blindness caused by cataract in persons of ≥50 years old in Liangyuan Residential District of Shangqiu City,Henan.Methods Cluster sampling was used in the study.Total of 5010 individuals aged ≥50 years from Liangyuan Residential District were selected randomly during Sep.2008 to Dec.2008.All individuals received eye examination,including the evaluation degree of lens opacity and cataract surgical conditions by slit lamp biomicroscopy.The age,sex,education status,prevalence of cataract and cataract surgical coverage rate were analyzed by the multivariate regression analysis.Results In 5010 individuals,cataract was found in 1158 cases （23.11%）.The prevalence of cataract was higher in the elderly female （P 〈 0.01）.In 96 eyes of 83 cases with cataract surgery,the modem extra-capsular cataract extraction was performed in 49 eyes （51.04%） and phocoemusification in 5 eyes（5.21%） respectively.The rate of intraocular lens implantation was 57.29%.Conclusion Cataract is the most common eye disease which lead to blindness and among elderly adults ≥ 50 years in Liangyuan District,Henan.In the district,there are low cataract coverage rate and the rate of intraocular lens implantation.
