Anti-VEGF therapy in myopic choroidal neovascularization: long-term results.
OBJECTIVE
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).


CONCLUSIONS
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.
