The Effects of the Water Drinking Test on Intraocular Pressure
The Effects of the Water Drinking Test on Intraocular Pressure of Glaucoma Patients Undergoing 24 Hour Continuous Monitoring With the SENSIMED Triggerfish
This clinical trial is designed to investigate the efficacy profile of the SENSIMED Triggerfish® during 24-hour IOP monitoring in patients with glaucoma or ocular hypertension, done three times at monthly intervals under different therapeutic regimen. This trial will also evaluate the efficacy of SENSIMED Triggerfish® to detect changes in intraocular pressure (IOP) after the water drinking test (WDT) will be investigated.
