Fibrin glue conjunctival autograft for primary pterygium: Overall outcomes and outcomes in expert versus trainee ophthalmologists.

INTRODUCTION

To determine outcomes of conjunctival autograft attached with fibrin glue (FG) for primary pterygium, and compare these outcomes in expert versus closely supervised trainee ophthalmologists.

METHODS

This was a retrospective, comparative, non-randomized, interventional study. Patients were recruited among those with primary nasal pterygium undergoing FG conjunctival autograft. Surgery was performed by expert (136 eyes) or closely supervised trainee (128 eyes) ophthalmologists. Mean follow-up was 7.82±8.23months. Main outcome measures were recurrence rate, reoperation rate and complications.

RESULTS

The study sample comprised 264 eyes of 225 patients. Participants were of mean age 47.09±12.89years; 46.7% were male, 28.4% Caucasian and 70.5% Hispanic. Recurrence was recorded in 6.4%: 5.9% in the expert group and 7% in the trainee group (P=0.704) and reoperation in 1.9%: 0.7% and 3.1% (P=0.202), respectively. Both groups showed similar rates of complications such as transient graft edema, graft dehiscence, hematoma or ocular hypertension. Reoperation was slightly more frequent in patients younger than 40years (P=0.064).

CONCLUSIONS

Good outcomes were observed for FG conjunctival autografting in primary pterygium surgery, with no differences recorded between supervised trainee and expert surgeons. Our findings suggest the need to supervise pterygium surgeries during training.
