Corneal melting after pterygium removal followed by topical mitomycin C therapy

Right corneal melting and scleral necrosis developed in a 77-year-old man 5 months after pterygium excision followed by topical administration of mitomycin C drops (0.4 mg/mL) for 4 weeks. We believe that these were delayed complications of the mitomycin C therapy, and we caution against prolonged use of the drug postoperatively.
