Various inflammations of the conjunctiva give rise to the formation of follicles that cannot be distinguished by inspection from those caused by trachoma; hence the formation of scar tissue is the one all important diagnostic feature of the disease. If trachoma had been called "scar producing conjunctivitis" much of the confusion of ideas and differences of opinion that now exist concerning the diagnosis of the disorder would never have arisen.
Clinically trachoma presents itself in two forms: (1) fulminating trachoma, and (2) slow trachoma.
