Abstract
PURPOSE: We report, for the first time, 2 cases of corneal ulceration and perforation after treatment with dupilumab for atopic dermatitis. METHODS: A 30-year-old woman and a 44-year-old man developed unilateral severe corneal ulceration and perforation while on dupilumab therapy after 3 and 9 months, respectively. RESULTS: Corneal cultures were negative in both cases except for scanty growth of Staphylococcus species on enrichment. Both cases progressed to perforation despite intensive topical antibiotic treatment. The first case required a tectonic keratoplasty to restore globe integrity after failed attempts of corneal gluing and multilayer amniotic membrane transplantation, and the second case was managed successfully with a cyanoacrylate glue patch. CONCLUSIONS: Although there have been previous reports of conjunctival injection and dry eye after dupilumab, these are the first 2 reports of corneal ulceration with rapid progression to perforation in patients under treatment with dupilumab. The underlying pathophysiology for ulcerative keratitis in these cases remains unknown, but there is no doubt that cessation of dupilumab prevented progression of the melting. Severe ocular symptoms while on dupilumab require a prompt discussion with the dermatology team to potentially switch treatment and halt further keratitis progression.
