Abstract
Purpose: To report the incidence of retinal pigment epithelium tears in eyes treated with aflibercept for neovascular age-related macular degeneration and compare it with ranibizumab, and to describe long-term visual outcomes of retinal pigment epithelium tears after intensive anti-vascular endothelial growth factor treatment.
Methods: Retrospective analysis of clinical charts, spectral domain optical coherence tomography and fundus fluorescein angiography imaging of consecutive naive patients treated with intravitreal aflibercept or ranibizumab for neovascular age-related macular degeneration.
Results: Eight hundred consecutive eyes were included in the study (300 treated with ranibizumab and 500 with aflibercept) with 34.0 ± 9.1 months of follow-up. The incidence of tears in the aflibercept group was 3.2% and 2.3% after ranibizumab (P = 0.52). Twenty-nine eyes with retinal pigment epithelium tears were followed for a mean of 30.76 months. Visual acuity at baseline was 20/100 (50.7 ± 19.3 Early Treatment Diabetic Retinopathy Study letters) and 20/200 (36.1 ± 26.1 Early Treatment Diabetic Retinopathy Study letters) at the end of follow-up. The mean number of injection was 7.3 at 12 months and 13.9 ± 8.1 at the end of the study. The number of injections positively correlated with the final visual outcome.
Conclusion: There was a low rate of retinal pigment epithelium tears after aflibercept injections, similar to ranibizumab. The correlation between the number of anti-vascular endothelial growth factors received and visual outcomes supports the need for continuing anti-vascular endothelial growth factor therapy.
