10 9. Clinical Presentation of Trachoma Trachoma: Grading System TF = Trachomatous inflammation - (follicles): five or more follicles, at least 0.5mm in size, on the 'flat' surface of the upper tarsal conjunctiva. TI = Trachomatous inflammation - (intense): inflammatory thickening of the upper tarsal conjunctiva with more than half of the normal deep tarsal vessels obscured. TS = Trachomatous scarring: scarring of the tarsal conjunctiva (fibrosis). TT = Trachomatous trichiasis: at least one eyelash rubbing on the eyeball or evidence of eyelash removal. CO = Corneal Opacity: where at least part of the pupil is blurred or obscured.
