A simple grading system for trachoma, based on the presence or absence of five selected "key" signs, has been developed. The method was tested in the field and showed good observer agreement, the most critical point being the identification of severe cases of the disease. It is expected that the system will facilitate the assessment of trachoma and its complications by non-specialist health personnel working at the community level.
一种基于五个选定“关键”体征的有无的沙眼简易分级系统已被开发出来。该方法在实地进行了测试，显示出观察者之间有良好的一致性，最关键的一点是对该疾病严重病例的识别。预计该系统将便于社区层面的非专业卫生人员对沙眼及其并发症进行评估。
