Further study details as provided by University of Zurich:

Primary Outcome Measures:
  • Change of endothelial function after 2 intravitreal injections and 8 weeks follow-up with ranibizumab or bevacizumab in patients with neovascular macular degeneration compared to patients with dry AMD. [ Time Frame: 8 weeks ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Change in inflammation markers, in oxidative stress, in mean, systolic und diastolic 24-hour blood pressure, in vascular compliance. Correlation of endothelial function with the number of endothelial progenitor cells. [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]

Estimated Enrollment: 75
