Outcome Measures

Primary Outcomes (1)

  • Percentage of Patients With at Least 10 Letters of Improvement in Best Corrected Visual Acuity (BCVA) From Baseline in the Study Eye

    BCVA is measured in the study eye using an eye chart and is reported as the number of letters read correctly (ranging from 0 to 100 letters). The lower the number of letters read correctly on the eye chart, the worse the vision (or visual acuity). An increase in the number of letters read correctly indicates improvement and a decrease in the number of letters read correctly indicates a worsening.

    Baseline, Month 12

Secondary Outcomes (4)

  • Change From Baseline in BCVA in the Study Eye

    Baseline, Month 12

  • Change From Baseline in Central Subfield Retinal Thickness in the Study Eye

    Baseline, Month 12

  • Change From Baseline in the Focal Leakage Area in the Study Eye

    Baseline, Month 12

  • Time to Retreatment in the Study Eye
