Scleral melting 16 years after pterygium excision with topical Mitomycin C adjuvant therapy

To report a case of scleral melting noted 16 years after pterygium excision with postoperative adjuvant topical Mitomycin C (MMC). Case report. A 61-year-old Malay gentleman underwent right nasal pterygium excision using bare sclera technique followed by topical MMC 0.1% for a week, 16 years ago. He was noted to have a right nasal scleral thinning with calcified plaque and granuloma. He was successfully treated conservatively without further progression of the scleral melting. Long-term complication of pterygium excision with adjuvant topical Mitomycin C may occur. The case shows that early detection and recognition of the complication can be sight saving.
