Purpose: To determine the 5-year outcome of intravitreal ranibizumab (IVR) for myopic choroidal neovascularization (CNV).

Method: We retrospectively analyzed the medical records of 51 eyes of 51 consecutive patients with myopic CNV who had been treated with IVR with a minimum follow-up period of 5 years after the initial IVR injection. The factors that predicted the best-corrected visual acuity (BCVA) at 5 years after IVR were determined by multiple regression analysis.

Results: The mean age of the subjects was 63.6 years, and the mean axial length was 29.4 mm. The mean number of IVR was 1.6, and 34 eyes (66.7%) had only a single IVR. At the baseline and at the 1-year, 2-year, 4-year, and 5-year period, the mean BCVAs were 20/49, 20/37, 20/41, 20/45, and 20/42, respectively. Stepwise multiple regression analysis showed that the BCVA at 5-year period was significantly correlated with the baseline BCVA, the number of IVR injections, and the size of the CNV-related macular atrophy.

Conclusion: Intravitreal ranibizumab provide a 5-year visual benefit in eyes with myopic CNV compared with the natural course. A lack of enlargement of the CNV-related macular atrophy, a better baseline BCVA, and a minimum number of IVR injections were associated with better visual outcomes.

The vision of 51 eyes with an active choroidal neovascularization was significantly improved over the baseline vision at 1 year after intravitreal injections of ranibiizumab but not at 2, 4, and 5 years. At 5 years, the visual acuity was significantly correlated with the size of the macular atrophy.
