Treat-and-extend Using Aflibercept for Type 3 Neovascularization

Summary

Type 3 neovascularization is a subtype of neovascular age-related macular degeneration (AMD) that is characterized by intraretinal neovascularization. Treat-and-extend (TAE) regimen is a widely-used, effective anti-vascular endothelial growth factor treatment regimen for neovascular AMD, regardless of subtypes of AMD. The purpose of the present study is to investigate the 18-month treatment outcome of TAE in type 3 neovascularization.
