The new trachoma grading system of WHO was followed in an epidemiologic survey of a rural sample population of 2,728 in Pingyin County, Shandong Province. The prevalence of trachoma was found to be 9.60%, and in children under 10 years of age, 3.69%. Trachoma was related with age; the rates of trachomatous inflammation-intense (TI), trachomatous scarring (TS), trachomatous trichiasis (TT) and corneal opacity (CO) all increased with aging. The epidemiologic significance of the grading system was discussed.
