Background/aim: The present study aimed to investigate the efficacy of mitomycin-C (MMC) and infliximab (INF) in reducing adhesion and fibrosis following strabismus surgery. Materials and methods: Forty eyes of 20 albino rabbits were separated into MMC and INF groups. Right and left eyes of rabbits were assigned to the drug and control groups, respectively. The superior rectus muscle was disinserted, the drug was administered to the surgical area for 5 min in the drug eyes (MMC 0.2 mg/mL or INF 5 mg/mL), and physiological saline was administered to the control eyes. Surgical areas were rinsed with 10 mL of physiological saline. The disinserted muscle was then sutured to the same area using 6.0 Vicryl. The rabbits were sacrificed after 4 weeks for histopathological examination. Results: Significant reduction was observed in fibrosis in the INF group as compared to the control group (P = 0.005). Although adhesion formation in the drug eyes reduced in the MMC and INF groups as compared to the control group, the difference was not significant (P = 0.280 and P = 0.579, respectively). Conclusion: This study demonstrated the fibrosis-preventing efficacy of IFN; thus, it can be a good option in reducing fibrosis in strabismus surgery.
