陕西省沙眼性倒睫和角膜混浊的控制现状

Prevalence of trachoma trichiasis and corneal opacity in the Shaanxi Province of China

目的：对陕西省沙眼性倒睫（trachoma trichiasis,TT）患病率进行估计,分析陕西省沙眼控制现状。方法：参照1987年WHO制定的沙眼简化分级标准,社区医生对陕西省居民共3 036.87万人口进行筛查,检查眼睑、睫毛、结膜和角膜组织,对陕西省沙眼性倒睫患病率进行估计,分析陕西省沙眼控制现状。结果：陕西省共收集987例TT,患病率为0.0325‰,其中男395例,女592例。年龄25~86岁,集中在60~80岁,〈50岁只有58例。12例TT患者合并角膜混浊（CO）,发生率1.2%。64例患者通过电解倒睫治愈,其余923例通过手术矫正。结论：陕西省TT患病率低于世界卫生组织对根治致盲性沙眼TT患病率降至1‰的定义,致盲性沙眼在陕西省不再属于公共卫生问题。

AIM： To assess the current situation of trachoma in Shaanxi Province and analyze its epidem iology and clinical features.METHODS： The World Health Organization（ WHO）sim plified trachom a grading system was used for the recognition and registration of cases of trachom a.Trachom a rapid assessm ent（ TRA） was conducted and30. 3687 m illion people from Shaanxi province were screened. Eyelids, eyelashes, conjunctiva and cornea were exam ined. The prevalence of trachom a trichiasis（ TT） in Shaanxi Province was estimated.RESULTS： Totally 987 cases with TT were collected in Shaanxi province,in which 395 cases were m ale and 592 cases were fem ale. The overall TT prevalence was0. 0325‰. The age of TT cases ranged from 25-86 years old,and concentrated in the 60-80 years old,only 58 cases were 〈50 years old. There were 12 cases of TT com bined corneal opacity（ CO） and the ratio was 1. 2%.Sixty-four patients were cured by electrolysis trichiasis,the rem aining 923 patients corrected by surgery interventions.CONCLUSION： Based on the results of this study,trachom a blind is no longer estim ated as a public health problem in Shaanxi province,as the detection rate of TT was less than 1‰ which is the goal of ＂elim ination of trachom a＂worldwide.
