  • Using the simplified WHO grading system14: TF = trachoma inflammation–follicular; TI = trachoma inflammation–intense; TS = trachomatous scarring.

  • Others: hordeolum (5), subconjunctival haemorrhage (3), acute conjunctivitis (7), pterygium (1), corneal ulcer (1), iris coloboma (1), suspected glaucoma (1), post evisceration (1).
