Letter to the Editor: Corneoscleral Melt 50 Years after Excision of Pterygium

PURPOSE To report a case of corneoscleral melt that occurred 50 years after resection of pterygium with postoperative administration of mitomycin C (MMC). RESULTS A 93-year-old woman developed acute corneal perforation and scleral melt in her left eye at 50 years after pterygium surgery with postoperative topical MMC. She underwent limbal transplantation. The anterior chamber reformed postoperatively and her intraocular pressure was normal. At 12 months after transplantation, best-corrected visual acuity was 20/500 and the graft-host junction was well apposed. CONCLUSION This case shows that corneoscleral melt can occur even 50 years after resection of pterygium combined with postoperative topical MMC.
