Purpose: To evaluate the medium- and long-term efficacy of anti-VEGF agents in the treatment of choroidal neovascularization secondary to pathologic myopia (mCNV).
Methods: We performed a retrospective analysis of patients with mCNV who had been treated with intravitreous anti-VEGF for at least 2 years. The best-corrected visual acuity (BCVA) and central retinal thickness (CRT) were compared before and after the treatment. The number of injections per year was also assessed.
Results: The results were analysed at 2 years for 67 eyes, at 3 years for 52 eyes, at 4 years for 28 eyes and at 5 years for 13 eyes. The mean change from baseline BCVA was significant at 2 years (+8.6 letters; p < 0.001) and this gain remained significantly stable for a period of 5 years. The mean CRT showed a significant decrease over time, with a nadir at 2 years (-104.0 μm; p < 0.001). The mean number of injections performed during the first year was 5.2, being lower in subsequent years (p < 0.001).
Conclusion: In this subset of patients with mCNV, an intravitreous therapy with anti-VEGF agents proved to have effective results over 5 years, with a sustained increase in BCVA.
