1987年，世界卫生组织（WHO）发布了一个简化的沙眼分级系统。该系统旨在供在社区一级工作的非专业人员使用，包括五种体征，每种体征在任何眼睛中都可能存在或不存在：（i）沙眼倒睫;（ii）角膜混浊;（iii）沙眼炎症-滤泡;（iv）沙眼炎症-强烈;和（v）沙眼瘢痕。虽然这些迹象对沙眼既不完全敏感，也不完全特异，但它们是识别需要干预以消除沙眼这一公共卫生问题的人群的重要工具。2018年，在世卫组织第四届全球沙眼科学会议上，对其中一种体征--沙眼倒睫的定义进行了修订，将只影响下眼睑的倒睫排除在外。本文件介绍了修订后的系统，更新了其介绍方式，提供了关于其使用的说明，并确定了正在进行辩论的领域。
A simplified grading system for trachoma was published by the World Health Organization (WHO) in 1987. Intended for use by non-specialist personnel working at community level, the system includes five signs, each of which can be present or absent in any eye: (i) trachomatous trichiasis; (ii) corneal opacity; (iii) trachomatous inflammation—follicular; (iv) trachomatous inflammation—intense; and (v) trachomatous scarring. Though neither perfectly sensitive nor perfectly specific for trachoma, these signs have been essential tools for identifying populations that need interventions to eliminate trachoma as a public health problem. In 2018, at WHO’s 4th global scientific meeting on trachoma, the definition of one of the signs, trachomatous trichiasis, was amended to exclude trichiasis that affects only the lower eyelid. This paper presents the amended system, updates its presentation, offers notes on its use and identifies areas of ongoing debate.
