OBJECTIVE: Superior conjunctival graft is commonly used in pterygium surgery, which may adversely affect the outcome of future filtration surgery. We retrospectively studied the success rate of inferior conjunctival autografting for primary pterygia in our unit. DESIGN: A noncomparative, retrospective, interventional case series. PARTICIPANTS: Thirty eyes of 27 patients treated between August 1996 and February 2001 with primary pterygia. INTERVENTION: Excision of pterygium followed by conjunctival autograft harvested from the inferior bulbar conjunctiva. Surgeries were performed by an experienced surgeon (CL) in 23 patients and by trainees in the remaining four cases. MAIN OUTCOME MEASURES: Recurrence of the pterygium and complications. RESULTS: Mean follow-up was 27 months (range, 8-53). Recurrence occurred in one eye (3.3%). This was a white female in her early fifties, with recurrence detected 3 months after the surgery. Conjunctival scarring at the donor site was observed in 11 eyes (36.66%). There was no symblepharon formation. There was no restriction of up gaze. Hemorrhage under the conjunctival graft developed in three eyes, corneal dellen near the limbus developed in four eyes, and epithelial inclusion cysts at the recipient site developed in two eyes. CONCLUSIONS: Inferior conjunctival autografting is an effective technique with a low recurrence rate. This is a useful technique in cases in which it is not possible or desirable to use the superior conjunctiva as a donor source.
