Subconjunctival and Intracorneal Bevacizumab Injection for Corneal Neovascularization in Lipid Keratopathy

Abstract

Purpose: The purpose of this study was to evaluate the efficacy and safety of subconjunctival and corneal intrastromal bevacizumab injections on corneal neovascularization in patients with lipid keratopathy. Methods: Three eyes of 3 patients with lipid keratopathy accompanied by corneal neovascularization received at least 2 subconjunctival and corneal intrastromal injections of bevacizumab (1.25 mg/0.05 mL, respectively) at 1-month intervals. Ophthalmic examinations, including visual acuity, tonometry; slit lamp biomicroscopy, and corneal topography, were performed before injection and every month thereafter. Results: All patients had marked regression of corneal neovascularization. Reduction in lipid deposition was noted in one patient. There were no adverse ocular or systemic events, except for a small intracorneal hemorrhage noted in one patient, which quickly and spontaneously cleared. Conclusion: Subconjunctival and intracorneal bevacizumab is a well-tolerated and effective method for obliterating corneal neovascularization in lipid keratopathy.
