Inhibition of Corneal Neovascularization by Topical Bevacizumab (Anti-VEGF) and Sunitinib (Anti-VEGF and Anti-PDGF) in an Animal Model

Topical administration of both bevacizumab and sunitinib inhibits corneal neovascularization in rabbits. But vascular endothelial growth factor (VEGF) pathway blockade by bevacizumab was not sufficient for a profound inhibition. Blocking both VEGF and platelet-derived growth factor pathways using sunitinib was 3-fold more effective.
