PURPOSE: To report a case of punctal-canalicular stenosis after topical mitomycin C use for corneal dysplasia. To the authors' knowledge, this association has not previously been described. DESIGN: Observational case report. METHOD: A 62-year-old woman was noted to have a right inferotemporal corneal dysplastic lesion. She received a topical course of mitomycin-C 0.04% four times a day, which subsequently invoked a toxoallergic reaction. One month later, the patient developed right-sided epiphora. RESULTS: Probing demonstrated complete stenosis of the right lower canaliculus, 5 mm from the punctum. CONCLUSION: Mitomycin-C use may lead to lacrimal apparatus fibrosis and symptomatic epiphora when inciting a toxoallergic reaction.
