Primary Outcome Measures:
  • Percentage of Patients With a Visual Field Improvement in the Study Eye [ Time Frame: Baseline, Month 6 ] [ Designated as safety issue: No ]
    Visual field improvement in the study eye is determined using the Humphrey Field Analyzer (HFA 24-2) full threshold test and clinical expertise. The Humphrey Field Analyzer is a machine that helps to map the field (peripheral) of vision. An improvement is an increase in the field of vision. The percentage of patients with a visual field improvement in the study eye is reported.


Secondary Outcome Measures:
  • Change From Baseline in Best Corrected Visual Acuity (BCVA) in the Study Eye [ Time Frame: Baseline, Month 6 ] [ 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). A positive change from baseline indicates an improvement and a negative change from baseline indicates a worsening.
