Intraoperative application of topical mitomycin C 0.05% for pterygium surgery.

Boletin de la Asociacion Medica de Puerto Rico 96(2):100 (2004) PMID 15580913

Pterygium recurrence is a common problem encountered by ophthalmic surgeons. Several methods have been suggested to avoid these recurrences. We studied the recurrence rate of pterygium after administration of a single intraoperative dosage of topical mitomycin C 0.05%. A retrospective analysis of fifty eyes in forty-nine patients who underwent pterygium excision by the same surgeon using intraoperative topical mitomycin C during the years 2002--2003. Mitomycin concentration was 0.05% applied to pterygium and adjacent areas after undermining and separation from sclera but prior to excision for three minutes. Postoperative follow up time was 12 months. The pterygium recurred in 4 (8%) eyes. Another four eyes (8%) had a cosmetically acceptable recurrence of < 2.0 mm. The only complication was a corneal dellen in one eye. Intraoperative administration of mitomycin C at 0.05% is safe and effective in preventing pterygium recurrences.
