Topical retinoid treatment for dry eye disorders

We have demonstrated the clinical efficacy of topical all-trans retinoic acid ointment in the treatment of four severe cases of the following dry eye disorders: Keratoconjunctivitis sicca, Stevens-Johnson syndrome, drug-induced pseudopemphigoid, surgery-induced dry eye. In all four cases, impression cytology confirmed that improvements in symptoms, visual acuity, keratopathy, and Schirmer test resulted from reversal of the process of squamous metaplasia. This treatment represents the first nonsurgical approach with action directed specifically at the diseased ocular surface epithelia.
