A variety of grading schemes have been proposed for the clinical classification of inflammatory trachoma. During a population based study of ocular disease conducted in southern Malawi we tested a simplified version of the current WHO grading scheme. Intraobserver agreement statistics were less than satisfactory for three of four graders. Interobserver agreement when compared against either a well experienced standard ophthalmologist or a consensus grade improved over time for two of the three graders. However, initial agreement for all three graders was only fair to moderate. Previous studies of trachoma grading schemes support these unsatisfactory results. A new system of classification is needed that is both accurate and reliable in a field setting.
针对炎性沙眼的临床分类，已提出了多种分级方案。在马拉维南部开展的一项基于人群的眼病研究中，我们对世界卫生组织现行分级方案的简化版进行了测试。四位分级者中有三位的观察者内一致性统计结果不尽人意。与经验丰富的标准眼科医生或共识分级相比，三位分级者中有两位的观察者间一致性随时间推移有所改善。然而，所有三位分级者的初始一致性仅为一般到中等。先前关于沙眼分级方案的研究支持了这些不尽人意的结果。需要一种在现场环境中既准确又可靠的新分类系统。
