Primary Outcome Measures:
  • Change from screening in mean diurnal IOP (mm Hg) at the Month 12 visit. [ Time Frame: 12 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Change in mean diurnal IOP vs. screening [ Time Frame: Month 24 ] [ Designated as safety issue: No ]
  • Change in screening in time-wise IOPs [ Time Frame: Various Month 12-60 ] [ Designated as safety issue: No ]
  • Proportion of responders [ Time Frame: Various 12-60 months ] [ Designated as safety issue: No ]
    A responder is defined as a subject with a certain target IOP value or a certain reduction of IOP as compared to screening. In the iStent inject group, a responder must not be on an ocular hypotensive medications or have had a postoperative procedure to reposition or remove stent(s) prior to the visit. Due to the lack of a complete consensus on the definition of a clinical responder, a set of target IOP values (e.g., downwards from 22 mm Hg in steps of 1 mm Hg) and reductions of IOP (e.g., downwards from the highest reduction in IOP in steps of 5%) will be evaluated.

Other Outcome Measures:
  • Adverse event reporting [ Time Frame: 0-60 months ] [ Designated as safety issue: Yes ]

    Rate of ocular adverse events through 60 months

    • Findings from IOP, best corrected visual acuity, visual field
    • Findings from slit-lamp, fundus and gonioscopic examinations
