Purpose: To evaluate the long-term treatment outcomes of bevacizumab therapy in patients with myopic choroidal neovascularization (CNV).
Methods: A retrospective review was performed of medical records regarding 43 eyes with myopic CNV that were treated with intravitreal bevacizumab injection. Visual acuity at diagnosis was compared with that measured at the final follow-up; the incidence and timing of re-activation were evaluated. In addition, factors associated with final follow-up were analyzed.
Results: Mean patient age was 39.3 ± 12.9 years and mean spherical equivalent (SE) was -11.9 ± 4.4 diopters. Patients were followed- up at a mean of 42.1 ± 17.0 months. Re-activation of the lesion was noted in 17 eyes (39.5%). The mean time to first re-activation was 19.5 ± 15.4 months from the time that resolution of subretinal fluid/retinal fluid was confirmed after initial treatment. The mean visual acuity (the logarithm of the minimal angle of resolution) was 0.40 ± 0.25 at diagnosis and 0.26 ± 0.31 at the final follow-up. Visual acuity at the final follow-up was significantly improved when compared with the baseline value (p = 0.005). Patient age (p < 0.001), SE (p = 0.003), and visual acuity at diagnosis (p < 0.001) were significantly associated with visual acuity at the final follow-up.
Conclusions: Bevacizumab therapy was a useful method for long-term treatment of myopic CNV. The observation of relatively late re-activation after the initial treatment suggests a need for continuous long-term follow-up.
