Off-label topical bevacizumab therapy against corneal neovascularization secondary to different corneal diseases was generally well-tolerated for up to 12 months. Bevacizumab (Avastin) eye drops inhibit corneal neovascularization, and lead to a reduction of the vessel diameter. Our results suggest that off-label use of Bevacizumab eye drops is a relatively safe and well-tolerated option for the treatment of corneal neovascularization. Care should be taken in patients with epithelial defects and neurotrophic keratopathy.
In this pilot study, fine-needle feeder vessel coagulation combined with topical bevacizumab application for treatment of mature corneal NV seemed to be a well-tolerated new treatment option to regress corneal NV. This may not only improve corneal transparency but also "preconditions" such a cornea for future keratoplasty.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
