“…Chronic blepharoconjunctivitis, Stevens-Johnson syndrome, herpes zoster, allergies, membranous or pseudomembranous conjunctivitis, and the long-term use of certain eyedrops, such as, idoxuridine, dipivefrin hydrochloride, or antiglaucoma topicals, are the causes of cicatricial entropion in the United States, although worldwide the most common cause of cicatricial entropion is trachoma. 1,2,[4][5][6] In the present study, the most common causative factor for cicatricial entropion was longstanding antiglaucoma eyedrops use. This condition is called 'pseudopemphigoid' because light microscopy, electron microscopy, and immunofluorescence microscopy demonstrate no differences between ocular cicatricial pemphigoid and a drug-induced pemphigoid-like condition.…”
