The anti-scar effect of tyrosine-kinase inhibitor nintedanib in experimental glaucoma filtration surgery in rabbits.

PURPOSE: To investigate the efficacy of nintedanib on preventing postoperative scar in formation following glaucoma filtering surgery (GFC) in rabbits in comparison with Mitomycin-C (MMC).

DESIGN: Experimental Animal Study.

METHODS: 24 New Zealand rabbits were divided randomly into 3 groups as Sham, Nindetanib and MMC(n = 8). Limbal-based trabeculectomy was performed on the right eyes of the rabbits. Left eyes that did'nt undergo surgery were included in the control group (n = 8). Following surgery, Intraocular pressures (IOP), postoperative complications and morphological changes in the bleb were evaluated. On the 28th day, eight eyes from each group were enucleated and histologically and immunohistochemically analyzed. Matrix metalloproteinase-2 (MMP-2), Transforming Growth Factor-1 (TGF-B1) and alpha-smooth muscle actin (a-SMA) were evaluated.

RESULTS: It was observed that nintedanib has no side effects and reduces subconjunctival fibrosis. Postoperative IOP values in the Nindetanib group were lower than the other groups (p < 0.05). The longest bleb survival was observed in the Nintedanib group and the shortest in the Sham group (p < 0.001). Conjunctival vascularity and inflammation was reduced in the Nintedanib group compared to the Sham group (p < 0.05). The highest subconjunctival fibrosis was observed in the Sham group and the least in the Nintedanib group (p < 0.05). Although the fibrosis score was found lower in the Nintedanib group compared to the MMC(p > 0.05). α-SMA TGF-β1, MMP-2 expressions were similar in Nintedanib and MMC groups (p > 0.05), however, it was observed that significantly decreased in both groups compared to Sham group (p < 0.05).

CONCLUSION: It has been observed that Nindetanib suppress fibroblast proliferation Thus, It may be a drug that can prevent subconjunctival fibrosis in GFC.
