ABSTRACT
To study the results of primary pterygium excision through bare sclera technique with and without intraoperative Mitomycin C use. This was an experimental study with randomised controlled trial. This study was conducted at Eye A unit, Khyber Teaching Hospital, Peshawar from May, 2007 to April,2009. One hundred patients with primary pterygium were selected from ophthalmology Deptt. OPD at Khyber Teaching Hospital, Peshawar. Detailed history was taken. Complete ocular examination done and those fulfilling inclusion criteria were included in the study. Anesthesia used was topical proparacaine 0.5% and local infiltration of 2% lignocaine. Mitomycine C [MMC] 0.02% [0.2mg/ml] was applied through a cotton swab at the bare part of the sclera for five minutes in 50 of these patients. Patients were followed up till three months. In bare sclera technique without MMC, recurrence rate was 70% [35 patients] while in MMC group, it was 16% [08 patients].There was one punctuate epithelial keratitis in MMC group and two cases of conjuntival granuloma one in each group. Pterygium excision through simple bare sclera technique had significantly high recurrence rate as compared to intraoperative use of MMC
