目的：沙眼是世界范围内感染性失明的主要原因。众所周知，这与贫困、获得保健服务和水的机会有限密切相关。2003年，世界卫生组织估计有8400万人患有活动性沙眼，760万人因沙眼而严重视力受损或失明：这项研究根据最新的可用信息提供了对全球沙眼患病率的最新估计。方法：对57个流行国家最近发表和未发表的调查进行了文献检索：调查的结果，使用世界卫生组织沙眼分级系统和其他信息，从区域和国家的专家作为一个基础，以确定沙眼的患病率在每个county.Results：人口为基础的调查提供了最新的信息，为42个流行的57个国家。40.6据估计，200万人患有活动性沙眼，820万人估计有倒睫。结论：目前估计的沙眼患病率低于以前的世卫组织估计：这可以解释的成功实施控制策略，更准确的数据，以及流行国家的社会经济发展。
Objectives: Trachoma is the leading cause of infectious blindness worldwide. It is known to be highly correlated with poverty, limited access to healthcare services and water. In 2003, the WHO estimated that 84 million people were suffering from active trachoma, and 7.6 million were severely visually impaired or blind as a result of trachoma: this study provides an updated estimate of the global prevalence of trachoma based on the most recent information available.Methods: A literature search of recent published and unpublished surveys in the 57 endemic countries was carried out: the result of surveys that used the WHO trachoma grading system and additional information from regional and country experts served as a basis to determine the prevalence of trachoma in each country.Results: Population-based surveys provided recent information for 42 out of 57 endemic countries. 40.6 million people are estimated to be suffering from active trachoma, and 8.2 million are estimated to have trichiasis.Conclusions: The current estimate of prevalence of trachoma is lower than the previous WHO estimates: this can be explained by the success in implementing control strategy, by more accurate data, as well as by socioeconomic development in endemic countries.
