Abstract

Introduction: Pterygium is a benign conjunctivo-elastic neoformation. Its surgical treatment is based on conjunctival autograft after complete surgical excision. The objective of our study is to evaluate the effectiveness of biological fibrin glue in the fixation of the conjunctival graft in comparison to 8/0 absorbable sutures. Patients and methods: we conducted a comparative study of a series of cases of pterygium operated using two different methods over a period of one year between January and December 2022 at the ophthalmology department of the international university Cheikh Khalifa hospital of Casablanca. Results: 30 cases were enrolled, the mean age was respectively 54 and 55.5 years in group 1 (sutures surgery) and group 2 (biological fibrin glue surgery). There was no gender predominance in the two groups. Regarding the stage of the pterygium, 3 were classified as stage 1, 12 classified as stage 2 and 15 classified as stage 3. In the both groups, no displacement of the limbo-conjunctival graft was found during the follow-up. Patients in group 2 (biological fibrin glue) showed fewer irritative symptoms compared to group 1 (sutures). The duration of the intervention was significantly reduced in group 2 (24,4 minutes) compared to group 1 (40,5 minutes). Furthermore, there were no significant differences in complication rate between the two groups. Conclusion: Despite a slight additional cost, the autologous limbo-conjunctival autograft fixed using biological fibrin glue could become the reference technique for the surgical management of pterygium due to its quickness and efficiency.
