环境污染及过量辐射与白内障发病的关系——广西柳州市白内障流行病学调查分析

The relationship between cataract and environmental pollution and exposure to ultraviolet and infrared rays-cataract epidemiology investigations and analysis of Liuzhou City,Guangxi Province.

目的 调查柳州市白内障流行状况 ,为指导工业城市白内障的防治提供理论依据。方法 1 997年对柳州市 38个单位 2 80 75例 (561 4 6眼 )人群进行视力、眼前段、裂隙灯复查晶状体情况。结果 白内障患者共 3792例 (741 1眼 ) ,总患病率为 1 3 50 %。高温生产中 ,接触红外线波长为 0 7～2 .5μm的炼钢铸铁工人 ,其白内障患病率为 1 7 85%。长期野外作业 ,接触过量紫外线人员的白内障患病率为 1 4 31 %。结论 柳州市属白内障高发区 ,红外线。

Objective To investigate the prevalence of cataracts in Liuzhou city,develop a guide for cataract prevention and treatment in the industrial city and suggest a theory for prevention and treatment of cataracts.Methods In 1997,the visual acuity and the anterior segment of the eye of 28075 persons(56146 eyes) were checked.The lgns was reviewed by using a slit lamp.Results 3792 cases (7411 eyes) had cataracts an incidence of 13.5%.The incidence among steel makers who work in the environment with high temperature and 0.7～2.5 μm infrared light was 17.85%.Long term occupational exposure to ultraviloet for those working outside has an incidence of 14.31%.Conclusion Liuzhou city has a high proportion of the population suffering from cataracts.This may be a result of infrared and ultraviolet rays exposure and high pollution levels.
