Rescue effects of intravitreal aflibercept in the treatment of neovascular age-related macular degeneration

We reported the rescue results of intravitreal aflibercept in patients with treatment-resistant neovascular age-related macular degeneration (AMD). We retrospectively analyzed eyes with neovascular AMD resistant to posterior subtenon triamcinolone, intravitreal ranibizumab, and/or bevacizumab treatment in a tertiary medical center in middle Taiwan between December 2013 and October 2014. We then switched treatment to 2.0 mg aflibercept. The main outcome included changes in best-corrected visual acuity and central foveal thickness measured by optical coherence tomography during monthly follow-up. There were 204 patients with neovascular AMD, and the percentage of refractory cases was 1.96% (4 of 204 cases). Our study included five eyes of four patients that were resistant to multiple treatments and subsequently switched to aflibercept. The mean age was 71.25 ± 11.09 years (range 57–83 years). Treatments were on average 6.6 times previously. Upon switching to aflibercept treatment, the average central foveal thickness on optical coherence tomography was 505.6 ± 270.86 μm (range 150–815 μm). After aflibercept treatment, the average central foveal thickness was 192 ± 51.76 μm (range 149–274 μm). All patients showed anatomic improvement, and 80% of the eyes (4 of 5 eyes) had improved best-corrected visual acuity and 20% of the eyes (1 of 5 eyes) had stable visual acuity. Patients tolerated the treatment well without serious adverse events. This short-term st...
