Outcome Measures

Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. 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 ]

Secondary Outcome Measures :
  1. Change in cardiovascular and ophthalmological parameters. [ Time Frame: 8 weeks ]
    Secondary outcomes include evaluation of retinal thickness as measured by optical coherence tomography (OCT), change in best-corrected visual acuity (BCVA), "Early Treatment Diabetic Retinopathy Study" (ETDRS) letters, ambulatory blood pressure, vascular compliance, biomarkers of vascular function and platelet function.
