1.2 Treatment of on-label naive AMD patients Recent randomized clinical trials (Marina, Anchor) have conclusively demonstrated that continued intravitreal therapy with ranibizumab in patients with subfoveal CNV from AMD leads to stabilization of vision in over 90% of patients and improvement in vision in at least a third of the patients and has led to the approval of ranibizumab (0.5 mg) for the treatment of neovascular AMD. Naive patients will be used in this study to determine if an improvement by ERG can be determined in those without prior therapy.
