There has been discussion regarding the definition of the clinical sign trachomatous trichiasis (TT) for the purposes of determining elimination of trachoma as a public health problem, and whether the definition should include the presence of trachomatous scarring (TS). A multi-country observational study was conducted in Ethiopia, Uganda, and Nigeria to assess whether TS grading by field graders using the WHO simplified system in trachoma surveys is comparable with expert grading of tarsal conjunctival scarring (TCS) using a detailed system.
