A potential therapeutic strategy for inhibition of corneal neovascularization with new anti-VEGF agents.

The factors triggering corneal neovascularization involve various growth factors. The data supporting a causal role for vascular endothelial growth factor (VEGF) in corneal neovascularization are extensive. One possible strategy for treating corneal neovascularization is to inhibit VEGF activity by competitively binding VEGF with a specific neutralizing anti-VEGF antibody. The vireo-retinal service in the recent years enjoyed a high level of success in managing choroidal neovascularization using anti-VEGF strategies. Efficacy and tolerability have been demonstrated for drugs targeting VEGF. We herein hypothesize that topical application of new anti-VEGF agents such as pegaptanib, ranibizumab and bevacizumab are potentially useful for inhibiting corneal neovascularization and restoration of corneal clarity. Further investigations are needed to place these medical treatments alongside corneal neovascularization therapeutics.
