Intravitreal Aflibercept for Therapy of Patients With Pseudoxanthoma Elasticum (PXE) (EyNeP)

May 5, 2019 updated by: Frank G. Holz, University Hospital, Bonn

Intravitreal Aflibercept (Eylea) for Therapy of Choroidal Neovascularization (CNV) and Fibrovascular Proliferation (FVP) in Patients With Pseudoxanthoma Elasticum (PXE)

The purpose of this study is to determine whether Aflibercept (Eylea) is effective in the treatment of choroidal neovascularization and fibrovascular proliferation in patients with pseudoxanthoma elasticum (PXE) in terms of preservation or improvement of visual acuity.
