Treatment of Polypoidal Choroidal Vasculopathy in Pachychoroid

Summary

This study will evaluate patients with diagnosis of polypoidal choroidal vasculopathy (PCV) in pachychoroid treated with combined therapy, consisting in photodynamic therapy (PDT) and 3 intravitreal therapy (IVT) of Aflibercept monthly. This is a single center, prospective case-series study. The investigators are going to evaluate Corrected Distance Visual Acuity (CDVA), disease activity, retinal and choroidal thicknesses and number of injection per year, during a twelve month follow up. The aim of this study is to verify if the combined therapy can act on the insult induced by the pachychoroid and on the neovascular lesion itself in this sub-population of patients with PCV in pachychoroid,
