Outcome Measures

Primary Outcome Measures

  1. Change from screening in mean diurnal IOP (mm Hg) at the Month 12 visit. [12 months]

Secondary Outcome Measures

  1. Change in mean diurnal IOP vs. screening [Month 24]

  2. Change in screening in time-wise IOPs [Various Month 12-60]

  3. Proportion of responders [Various 12-60 months]

    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

  1. Adverse event reporting [0-60 months]

    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
