Purpose: To report 7 cases of recurrent corneal neovascularization (NV) and lipid deposition after subconjunctival injection of bevacizumab for the treatment of corneal NV–induced lipid keratopathy.
Methods: We conducted a prospective interventional case series that included 20 eyes of chronic lipid keratopathy that received bevacizumab injection for the treatment of corneal NV and lipid deposition, including 7 eyes with recurrent corneal NV and lipid deposition after ceasing treatment. Repeated subconjunctival injections of bevacizumab were performed in 5 patients with recurrence. Penetrating keratoplasty was performed in 1 patient who had severely recurrent lipid deposition. Clinical presentation of corneal NV and lipid deposition, best-corrected visual acuity, and complications after treatments were recorded.
Results: Bevacizumab inhibited corneal NV and lipid depositions in 19 patients. Seven of the 20 patients (35%) had different patterns of recurrence of corneal NV/lipid deposition 6 to 15 months after discontinuing treatment. Five of the 7 patients in whom corneal NV/lipid deposition was recurrent received another course of repeated bevacizumab treatments. Three eyes had partial response to the second course of treatment. Two eyes had too short re-treatment course to have conclusions. One patient who received penetrating keratoplasty had successful result after surgery.
Conclusions: Corneal NV and lipid deposition may recur after ceasing the subconjunctival bevacizumab injections for lipid keratopathy. Some patients respond at least partially to repeated injections.
