Purpose: To determine the efficacy and safety of pterygium excision with a small conjunctival graft harvested at the limbus. Methods: Patients presenting between November 2001 and November 2002 with symptomatic or visually significant pterygia underwent surgery. Conventional excision of the pterygium head was followed by a superficial mini-conjunctival graft harvested from the superior limbus. The dimensions of the mini-conjunctival graft were 1-1.5 mm in width (including an edge of superficial cornea) by 2-3 mm in length. This was grafted over the area of the removed pterygium using four interrupted vicryl sutures. The eye was patched with tobradex ointment postoperatively. All operations were performed under topical anesthesia in a minor procedure room with an operating microscope. Results: Thirty-six patients with a total of 49 eyes operated on were included in the study. Two eyes had temporal pterygia while 47 were nasal. One eye had recurrent pterygium while 48 were primary. Six patients were African American while the remaining 30 were Hispanic. Seventeen patients were male and 19 were female. All patients tolerated the procedure well. Recurrence was defined as pterygium growth over the limbus of 2mm or more. In 49 eyes operated on with the mini-conjunctival graft there was one recurrence. Conclusions: This series of patients showed the pterygium excision with mini-conjunctival graft, performed under topical anesthesia in a minor procedure setting, can be done safely and effectively.
