The range of polypoidal choroidal vasculopathy (PCV) and pachychoroid neovasculopathy covers to be discussed. When the usage of PCV is limited to “pachychoroid driven disease with polypoidal lesion”, pachychoroid neovasculopathy should cover the range of “pachychoroid-driven disease with choroidal neovascularization (CNV) but without polypoidal lesion” (A). When both “drusen-driven CNV with polypoidal lesion” and “pachychoroid-driven CNV with polypoidal lesion” into PCV, then “pachychoroid neovasculopathy without polypoidal lesion” should be true pachychoroid neovasculopathy and “drusen-driven neovascular AMD without polypoidal lesion” might have to be called “drusen-driven typical neovascular AMD” (B). When we apply pachychoroid neovasculopathy regardless of the existence of a polypoidal lesion, “drusen-driven neovascular AMD with polypoidal lesion” might be called PCV (C).
