Trachoma is a bilateral, chronic, and recurrent keratoconjunctivitis, following infection
by the bacterium Chlamydia trachomatis, which leads to painful corneal abrasion and
profuse modifications of the ocular surface, eventually causing blindness. It is considered
accountable for the visual impairment of about 2.2 million people worldwide, of whom
1.2 million are irreversibly blind, and is estimated to be endemic in more than fifty
countries. [

] Clinical findings of this disease include involutions of the peripheral cornea due
to intense follicular conjunctivitis (Herbert pits), thickening and papillary hypertrophy
of the upper tarsal conjunctiva with the presence of thick white, fibrotic bands (Arlt´s
line), trichiasis and severe dry eye [

] Corneal changes are the hallmark of the final blinding stage which embraces the
clinical triad of pannus, epithelial vascularisation and infiltration [
