What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Decrease From Baseline in Intraocular Pressure at Week 8 Predose	Comparison of each group in change from baseline in intraocular pressure. Arm of "a treatment group coming together with latanoprost / carteolol" is a reference group． As for "Primary Outcome" and "Secondary Outcome" analysis , the OPC-1085EL group was compared only to the carteolol group, not to the latanoprost/carteolol concomitant group.	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. Arm of "a treatment group coming together with latanoprost / carteolol" is a reference group． As for "Primary Outcome" and "Secondary Outcome" analysis , the OPC-1085EL group was compared only to the carteolol group, not to the latanoprost/carteolol concomitant group. 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. Arm of "a treatment group coming together with latanoprost / carteolol" is a reference group． As for "Primary Outcome" and "Secondary Outcome" analysis , the OPC-1085EL group was compared only to the carteolol group, not to the latanoprost/carteolol concomitant group.
