A new simplified grading system for trachoma, which is based on the presence or absence of five selected key signs, has been assessed. The level of inter-observer variation and of variation for individual observers (intra-observer variation) showed that the system had good reproducibility following a training period that included interactive clinical teaching. The grading scheme was quickly learned by experienced ophthalmologists and auxiliary health personnel (ophthalmic nurses). The scheme should therefore be suitable for widespread application in field surveys of trachoma.
一种基于五个选定关键体征的有无的新的简化沙眼分级系统已得到评估。观察者间变异水平和个体观察者的变异（观察者内变异）表明，在包括互动临床教学的培训期后，该系统具有良好的可重复性。经验丰富的眼科医生和辅助卫生人员（眼科护士）能很快学会该分级方案。因此，该方案应适用于沙眼现场调查的广泛应用。
