Resolution of Refractory Corneal Neovascularization with Subconjunctival Bevacizumab.

Abstract
Corneal neovascularization (CNV) has a variety of causes and threatens corneal clarity, thus optimal visual acuity. Conventional medical management includes topical steroids and matrix metalloproteinase inhibitors like doxycycline. Anti-vascular endothelial growth factor (anti-VEGF) agents have demonstrated promise but remain off-label for this indication. However, these agents hold value in cases refractory to first-line medical management. We report the case of a 63-year-old woman who presented with ocular rosacea and CNV affecting vision, on a background of acne rosacea. She was initially treated with fluorometholone and doxycycline, yet continued to deteriorate. Eventually she received two 1.5-mg subconjunctival injections of bevacizumab 2 months apart. CNV completely resolved and results were maintained at 4-year follow-up. This case demonstrates that refractory CNV can be effectively treated with subconjunctival injection of anti-VEGF bevacizumab. The resolution of CNV was also maintained years after injection with minimal adjunctive therapy during this period, and to our knowledge there are no other studies reporting a follow-up period of 4 years after treatment. This is a pertinent case for other clinicians treating patients in a similar situation.
