Long-Term Results of Pro Re Nata Regimen of Aflibercept Treatment in Persistent Neovascular Age-Related Macular Degeneration.

Abstract：

PURPOSE:To determine the 24-month results of patients who had pro re nata (PRN) aflibercept treatment owing to recurrent or resistant neovascular macular degeneration. DESIGN:Retrospective, interventional, consecutive case series. METHODS:Eighty-one eyes of 78 patients with resistant or multiple recurrences of intraretinal or subretinal fluid while receiving monthly bevacizumab or ranibizumab injections and were switched to strict, as-needed aflibercept treatment with every-8-weeks spectral-domain optical coherence tomography (SDOCT)-guided monitoring were included. If there was a persistence of fluid despite this treatment, more frequent aflibercept injections were considered. Anatomic outcomes including maximum retinal thickness, central macular thickness, maximum pigment epithelial detachment height, maximum fluid height, and visual acuity (VA) were assessed at given follow-ups. RESULTS:All anatomic endpoints significantly improved following 3 consecutive aflibercept injections, which were maintained through 24 months (P < .05 for all endpoints at all visits). Thirty-seven eyes (45.6%) required more frequent injections with monthly SDOCT-guided monitoring at a median of 37 weeks (interquartile range, 30-62 weeks) to adequately treat the retinal fluid. Seventy-one of 81 eyes (87.7%) became completely dry on at least 1 follow-up visit; however, there was no significant improvement in VA during the study period. CONCLUSION:Aflibercept injection with an as-needed regimen was effective in many eyes previously treated with monthly bevacizumab or ranibizumab injections that had persistent or recurrent fluid. Despite significant improvement in anatomic outcomes, vision remained stable throughout the 2-year follow-up, likely because this cohort of patients had advanced choroidal neovascular membrane upon enrollment (recurrent or resistant).
