Plasma Levels of Vascular Endothelial Growth Factor Before and After Intravitreal Injection of Aflibercept

The purpose of this study is to examine the plasma concentration of vascular endothelial growth factor (VEGF) after standard treatment with one of the newest growth factor inhibitors, aflibercept (Eylea). Patients with exudative age-related macular degeneration (AMD) are treated today with anti-growth factors (anti-VEGF). Eylea appears to have a longer duration of action in the eye and a more powerful effect on the edema in the macula than previously used growth factor inhibitors. This means that the disease can be controlled with fewer number of injections into the eye and the investigators can therefore reduce the risk of complications associated with this type of treatment. It is unclear what the plasma VEGF concentration after treatment with Eylea into the eye in patients with wet age-related macular degeneration is.
