Primary Outcome Measures:
  • Proportion of Subjects Achieving a 20% or Greater Reduction in IOP From Baseline on the Same or Less Number of Medications [ Time Frame: 12 Months ]
    Proportion of subjects achieving a 20% or greater reduction in IOP from baseline on the same or less number of medications. Subjects who underwent a glaucoma-related secondary surgical intervention prior to the 12-month visit were considered failures in this analysis.

  • Mean Change in IOP From Baseline [ Time Frame: 12 Months ]
    Mean change in IOP from baseline was calculated for subjects who completed the 12-month visit and the worst within-eye IOP was used for subjects who underwent a glaucoma-related secondary surgical intervention.

Enrollment: 65
Study Start Date: January 2013
Study Completion Date: August 2016
Primary Completion Date: February 2016 (Final data collection date for primary outcome measure)
