2. Aim To evaluate the results of Conjunctival Limbal Autograft(CLAU) with Fibrin glue with Mitomycin-C (MMC)in the management of Recurrent Pterygium.

3. Methods Retrospective review of 12 eyes of 12 patients presenting with recurrent pterygium was done. All patients had previous failed pterygium surgeries in the form of recurrences.

4. Methods Surgical technique included Pterygium excision, followed by application of intra-operative 0.02% Mitomycin-C for 30 seconds, followed by sutureless Conjunctival Limbal Autograft (CLAU) which was affixed with Fibrin glue. Conjunctival-limbal autograft was measured and harvested from the superotemporal bulbar conjunctiva. If the superotemporal bulbar conjunctiva was unhealthy and scarred, the graft was harvested from the inferior bulbar conjunctiva or the superotemporal bulbar conjunctiva of the contralateral eye.

5. Surgical technique of Pterygium Excision with conjunctival autograft with Fibrin Glue

6. Results Mean age of the patients was 40.08+/-16.52 years. Mean follow up period was 10.5+/-3.6 months. Mean number of previous surgeries were 1.33+/- 0.65 (range 1-3). All patients were symptomatically comfortable in the immediate post-operative period. Post-operative surface inflammation was minimal.

7. Results No major post-operative complications were noted. One patient (8.3%) had a small granuloma at the recipient bed whereas One had retraction (8.3%) of the autograft at day one. There were no recurrences noted in any of the patients during the follow up period. (0%)

8. Recurrent Pterygium Pterygium Excision with Conjunctival limbal Autograft + MMC + Fibrin Glue 10 days post-operative

9. Recurrent Pterygium Pterygium Excision with Conjunctival limbalAutograft + MMC + Fibrin Glue 1 week post-operative

10. Discussion The use of conjunctival-limbal autograft is associated with an extremely low recurrence rate (0-5%) 1-4 Conjunctival autograft with Fibrin glue is associated with decreased surgical time, a quieter eye postoperatively, and better patient comfort. Fibrin glue is a biological tissue adhesive which imitates the final stages of the coagulation cascade when a solution of human fibrinogen is activated by thrombin, which are respectively the two components of the glue. The use of intraoperative Mitomycin C 0.02% further helps in reducing the postoperative recurrence and scarring. 5

11. Conclusions CLAU with Fibrin glue with MMC is an effective technique in the management of Recurrent Pterygium.
