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。

METHODS: The World Health Organization(WHO)simplified trachoma grading system was used for the recognition and registration of cases of trachoma. Trachoma rapid assessment(TRA)was conducted and 30.3687 million people from Shaanxi province were screened. Eyelids, eyelashes, conjunctiva and cornea were examined. The prevalence of trachoma trichiasis(TT)in Shaanxi Province was estimated.

RESULTS: Totally 987 cases with TT were collected in Shaanxi province, in which 395 cases were male and 592 cases were female. The overall TT prevalence was 0.0325‰.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 combined corneal opacity(CO)and the ratio was 1.2%. Sixty-four patients were cured by electrolysis trichiasis, the remaining 923 patients corrected by surgery interventions.

CONCLUSION: Based on the results of this study, trachoma blind is no longer estimated as a public health problem in Shaanxi province, as the detection rate of TT was less than 1‰ which is the goal of “elimination of trachoma” worldwide.
