Outcome Measures
Primary Outcomes (1)
Change From Baseline in Best Corrected Visual Acuity (BCVA) at Month 6
BCVA is measured in the study eye using an eye chart and is reported as the number of letters read correctly ranging from 0 (worst) to 100 letters (best). A positive number change in the number of letters read correctly means that the vision improved and a negative number change in the number of letters read correctly means that the vision has worsened.
Baseline, Month 6
Secondary Outcomes (11)
Change From Baseline in Central Retinal Thickness (CRT) at Month 6
Baseline, Month 6
Change From Baseline in BCVA at Month 12
