Nine-Year Outcome of Ranibizumab Monotherapy for Choroidal Neovascularization Secondary to Pathologic Myopia

PURPOSE: The aim of this study was to evaluate the 9-year outcome of ranibizumab monotherapy for myopic choroidal neovascularization (mCNV). METHODS: This was a retrospective, nonrandomized, multicentric study to evaluate the long-term outcomes of mCNV treated with ranibizumab monotherapy for at least 9 years according to a strict pro re nata regimen. RESULTS: Seventeen eyes of 17 patients (12 women, mean age 57.9 ± 7.7 years) were included. The mean follow-up period was 112.4 ± 3.9 months (range 108-120). The mean difference in best-corrected visual acuity (BCVA) from baseline to the last follow-up was +1.2 ± 15.6 ETDRS letters (p = 0.004, between initial vs. 12 and 24 months). The mean total number of intravitreal injections for each patient was 1.24 ± 1.70 per year (range 2-25). No systemic adverse reactions related to the drug treatment were detected during the 9-year follow-up period. CONCLUSIONS: Long-term ranibizumab monotherapy treatment induces unchanged or better BCVA compared to baseline after a 9-year treatment in almost all eyes.
