Study of the Long-Term Effect of Frequent Anti-VEGF Dosing on Retinal Function in Patients With Neovascular AMD

THis study aims to determine whether frequent dosing of intravitreal injections of Ranibizumab (Lucentis) or Bevacizumab (Avastin), which act as VEGF inhibitors, has a deleterious effect on the retina, studied by electrophysiologic testing.

This prospective, non-randomized clinical study will include patients assigned to intravitreal injection of Ranibizumab or Bevacizumab due to neovascular AMD. The patients will undergo repeat ophthalmic evaluation and intravitreal injections every 4-6 weeks, as long as will be deemed necessary. Periodic electrophysiologic evaluation including Electroretinogram (ERG), electro-oculogram (EOG) and Visual Evoked Potentials (VEP) tests will be performed every 3 months.
