研究组 & 干预措施
Timolol/Dorzolamide
Timolol/Dorzolamide, 1 drop, twice daily, for 12 weeks
干预措施: timolol/dorzolamide combination (Drug)
结局指标
主要结局
Mean Change in the Peak Intraocular Pressure (IOP) Measured Two Hours After Study Drug Administration at Week 12 Compared to Baseline IOP.
时间窗: Baseline and 12 weeks
The therapeutic goal of normal tension glaucoma treatment includes lowering IOP to prevent progression of damage in optic nerves or vision. In this trial, IOP was measured with the same tonometer throughout the study. A decreased IOP from baseline is considered an improvement. IOP was measured in both eyes and the eye with the higher IOP was used for the participant.
次要结局
- Mean Change in Trough IOP Measured Right Before Study Drug Administration at Week 12 Compared to Baseline IOP.(Baseline and 12 weeks)
- Mean Change in IOP 8 Hours After the Study Drug Administration at Week 12 Compared to Baseline IOP(Baseline and 12 weeks)
