What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Decrease From Baseline in Intraocular Pressure |  | Baseline, week 8 predose | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Intraocular Pressure at Week 8 Predose | Comparison of each group in intraocular pressure at Week 8 Predose. The number of subjects showed in the Participant Flow comes from all the subjects administered IMP. For efficacy analysis, on the other hand, several subjects were excluded from the analysis according to the statistical analysis plan. For example, subjects without IOP after administration were excluded. In addition, IOP measurement at 8 hours was not mandatory. That is why there are differences between the number in the Participant Flow and Outcome. | Week 8 Predose | 
| Intraocular Pressure at Week 8 at 2 Hours After IMP Administration | Comparison of each group in intraocular pressure at Week 8 at 2 hours after IMP administration. The number of subjects showed in the Participant Flow comes from all the subjects administered IMP. For efficacy analysis, on the other hand, several subjects were excluded from the analysis according to the statistical analysis plan. For example, subjects without IOP after administration were excluded. In addition, IOP measurement at 8 hours was not mandatory.
