A 68-year-old male developed foreign body sensation in both eyes,photophobia and tearing in the right eye approximately 6 weeks after initiating dupilumab for severe atopic dermatitis.The right eye presented a crescent-shaped superficial-stromal ulcer in the peripheral cornea with an undermined edge,which was separated from the limbus of the cornea by a clear zone.The left eye had a pannus at the limbus of the cornea.Corneal scraping,bacterial culture,and fungal culture excluded infections.The patient was administered 0.1%fluorometholone eye drops and recombinant bovine basic fibroblast growth factor eye drops.The patient's condition continued to improve during the follow-up period.At the revisit 82 days after the initial diagnosis,the corneal lesions of the right eye were basically healed,and the corrected visual acuity increased from 0.5 to 1.0.
