Best-corrected visual acuity (BCVA), optical coherence tomography (OCT) at baseline and final visit, and drug-related adverse events were analyzed. Eyes with recurrent macular fluid on IVBr every 8 weeks were treated with a combination therapy alternating between IVBr and aflibercept every month.Results: Among 52 eyes (40 patients) on IVBr, all had been previously treated with other anti-VEGF therapy, with 73% having persistent macular fluid. After a mean follow-up of 46.2± 27.4 weeks on IVBr, the mean treatment interval for intravitreal therapy increased to 8.8± 2.1 weeks on IVBr from a baseline of 6.1± 3.1 weeks (p< 0.001). Macular fluid decreased and BCVA was stable/improved in 61.5% of eyes on IVBr. Ten eyes with increased macular fluid on IVBr monotherapy when extended to every 8 weeks were treated with combination therapy alternating betwe
