Study Details

Study Description

Brief Summary

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.

Condition or Disease Intervention/Treatment Phase
  • Device: SENSIMED Triggerfish
N/A

Detailed Description

The investigation will recruit male and female patients 18-80 years old and diagnosed with glaucoma or ocular hypertension requiring hypotensive ocular treatment. Up to 100 subjects will be enrolled in the study to ensure a minimum of 80 completing three IOP fluctuation monitoring sessions. Patients will be considered enrolled in the study upon signature of informed consent. A screening visit and three 26-hour IOP fluctuation monitoring sessions are planned for each patient. IOP monitoring sessions will be carried out in ambulatory mode at 4 week intervals (plus/minus 7 days). All subjects will be monitored during the same period of the day (± 1hr). The expected duration of participation for each patient is of 3.5 days over three to four months. Patients will be recruited over a 16-month period. The total expected study duration is 16 months.
