This article reports a rapid response of intravitreal aflibercept for the treatment of a case of neovascular age-related macular degeneration that developed tachyphylaxis to bevacizumab and ranibizumab. An 80-year-old man with neovascular age-related macular degeneration became unresponsive to monthly treatment with bevacizumab or ranibizumab after initial responsiveness, to as-needed treatment with these antivascular endothelial growth factor drugs for 49 months. Subretinal fluid and pigment epithelial detachment had sustained in spite of 14 bevacizumab and seven ranibizumab injections prior to intravitreal aflibercept treatment. After only one injection of intravitreal aflibercept, a marked improvement was seen within 1 week. Complete drying of subretinal fluid and marked subsidence of pigment epithelial detachment were noted 4 weeks after the first aflibercept injection and sustained for three consecutive monthly injections. This case reveals that shifting to aflibercept may be an effective alternative treatment for neovascular age-related macular degeneration that becomes tachyphylactic to bevacizumab or ranibizumab.
