Outcome results
Change of Intraocular Pressure (IOP) From Baseline to Week 8
Value at Week 8 minus value at baseline
Time frame: Baseline to Week 8
Population: The primary efficacy analysis population was the Intent-to-treat population (ITT) which consisted of all subjects treated with the study drug as randomized. If there were any missing IOP values at Week 8, the data were supplemented by LOCF (Last Observation Carried Forward) using data at Week 4.
