Primary Outcome Measures:
  • Average Change From Baseline in Best Corrected Visual Acuity (BCVA) in the Study Eye [ Time Frame: Baseline, 12 Months ] [ Designated as safety issue: No ]
    BCVA is measured using an eye chart and is reported as the number of letters read correctly (ranging from 0 to 100 letters) in the study eye. The lower the number of letters read correctly on the eye chart, the worse the vision (or visual acuity). The average BCVA is calculated across study visits for each patient. A positive number change from baseline indicates an improvement and a negative number change from baseline indicates a worsening.


Secondary Outcome Measures:
  • Change From Baseline in Foveal Thickness Measured by Optical Coherence Tomography (OCT) in the Study Eye [ Time Frame: Baseline, Month 12 ] [ Designated as safety issue: No ]
    OCT is a laser based non-invasive diagnostic system providing high-resolution imaging sections of the fovea (part of the retina) in the study eye after pupil dilation. A negative change from baseline indicates an improvement (less foveal thickness) and a positive change from baseline indicates a worsening (more foveal thickness).

  • Change From Baseline in Total Area of Macular Leakage in the Study Eye Measured on Fluorescein Angiography (FA) [ Time Frame: Baseline, Month 12 ] [ Designated as safety issue: No ]
    FA is a technique for examining the circulation of the retina (and detecting any leakage) using a dye-tracing method. Photographs are taken with a specialized low-power microscope with an attached camera designed to photograph the interior of the eye, including the retina and optic disc. A negative change from baseline indicates a decrease in leakage (improvement) and a positive change from baseline indicates an increase in leakage (worsening).
