Use of an Ocular Telemetry Sensor in Tafluprost Treated Patients

Study Overview
=================
Brief Summary
-----------------
This clinical trial is designed to investigate the performance of SENSIMED Triggerfish® during 24-hour continuous IOP fluctuation monitoring, defined as the number of valid recording intervals over the 24-hour period. The investigation will recruit male and female patients older than 18 years and diagnosed with glaucoma and treated with tafluprost in both eyes. 20 subjects will be enrolled in the study. Patients will be considered enrolled in the study upon signature of informed consent. A screening visit and one 24-hour IOP fluctuation monitoring session during a 36-hour hospitalisation, are planned for each patient.

Eligibility Criteria
-----------------
Inclusion Criteria: Older than 18 years. Untreated IOP of ≥22 mmHg in both eyes. Documented, typical glaucomatous visual field (VF) loss (nasal step, or arcuate, paracentral or Seidel's scotoma) determined by automated static threshold perimetry (Octopus 100), and glaucomatous optic nerve head cupping (neural rim notching or saucerization) in both eyes.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Acquisition of 24-hour Sensor output signal | Performance is assessed as the portion of valid data (actual number of valid data points recorded compared to expected number of recorded data points) during 24-hour recording. | After 24-hour continuous recording | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Possible IOP fluctuation | Fluctuation is defined as a change of 25% or more from the mean Sensor output over 24 hours for each participant. | After 24-hour recording with study device |
