Comparison of fibrin glue and sutures for attaching conjunctival autografts after pterygium excision.

PURPOSE: To compare the efficacy and safety of fibrin glue and suturing for attaching conjunctival autografts among patients undergoing pterygium excision.

DESIGN

Prospective, randomized, interventional case series.

PARTICIPANTS

Twenty-two patients undergoing excision of primary pterygium.

METHODS

A superior conjunctival autograft was harvested and transferred onto bare sclera after pterygium excision. Fibrin glue (Beriplast P) was used to attach the autograft in 11 eyes and nylon 10-0 suture was used to attach the autograft in 11 eyes. The patients were followed up for 2 months.

MAIN OUTCOME MEASURES: Graft success, recurrence rate, operating time, patient comfort.

RESULTS

All conjunctival autografts in both groups were successfully attached and were intact after 2 months. The average operating time for the fibrin glue group was significantly shorter (P<0.001). Postoperative symptoms were fewer for the fibrin glue group than the suture group. One patient (9%) from the fibrin group experienced subconjunctival hemorrhage, and 1 patient (9%) from the suture group experienced partial graft dehiscence.

CONCLUSIONS

Fibrin glue is a safe and effective method for attaching conjunctival autografts. The use of fibrin glue results in shorter operating times and less postoperative discomfort.
