Outcomes
Primary Outcome Measures
Subjects observed at Month 12 who experience a mean medicated diurnal IOP reduction of ≥ 20% vs. baseline mean diurnal IOP
Primary: Subjects observed at the Month 12 visit who experience a mean diurnal IOP reduction of ≥ 20% vs. baseline mean diurnal IOP, had no glaucoma surgical procedures (incisional or laser surgery prior to the 12 month visit), and no postoperative procedure to reposition or remove the stent prior to the 12 month visit, or additional ocular hypotensive medications within 4 weeks of the Month 12 visit
Secondary Outcome Measures
Mean diurnal IOP < 18mm Hg
Secondary: Subjects observed at the Month 12 visit who experience a mean diurnal IOP < 18 mmHg, had no glaucoma surgical procedures (incisional or laser surgery) prior to the 12 month visit, and no postoperative procedure to reposition or remove the stent prior to the 12 month visit or additional ocular hypotensive medications within 4 weeks of the Month 12 visit
