Abstract

Purpose
We report two cases of corneal neovascularization (NV) after burn injury successfully treated by subconjunctival bevacizumab injections at 2-week intervals.
Case summary
Three bi-weekly subconjunctival injections of bevacizumab were administered to two patients with corneal NV after burn injury. In our first patient, corneal NV was markedly reduced by bevacizumab injection. The patient exhibited with a clear cornea and improved visual acuity (20/30) after treatment. Eleven weeks after the last injection, the cornea remained clear, with clinical regression of smaller vessels; the improvement in visual acuity was maintained. In the second case, the diameter of the vessels, hemorrhagic lesions, and corneal edema decreased/regressed, with improvement of the visual acuity to 20/25; these improvements persisted for 12 weeks after the last subconjunctival injection.
Conclusions
Our results suggest that bi-weekly subconjunctival injection of bevacizumab is well-tolerated and effective for inhibiting chronic corneal NV after burn injury.
