Rubbing of Mitomycin . C in the surgical treatment of pterygium versus Bare. Scleral technique

Abstract

Abstract Background: The recurrence rate of pterygia after excision is high. Objective: To determine the effect of rubbing mitomycin-C combined with operation on reduction of the recurrence rate of pterygia, compared to surgical treatment. Methods: 32 patients with pterygium who were operated by bare-scleral technique in Avi-Cina hospital of Qazvin during 1996 to 1998 were understudy in which 15 cases were treated by surgery (control group) and 17 cases by rubbing mitomycin-C (0.2 mg/ml) combined with surgery intraopratively and postopratively once a day for three consequative days. The average length of follow-up was 18 ± 3 months. Findings: The recurrences rate of pterygium operated by mitomycin-C was 5.9% which appeared four months after the operation and 40% in control group (P
