About this study

Official title: Detection of Induced IOP Fluctuations by SENSIMED Triggerfish® in Pigmentary Syndrome and Glaucoma Patients

This study monitors the intraocular pressure (IOP) over 4 to 6 hours using the SENSIMED Triggerfish® device and Goldmann Applanation Tonometry (GAT) in pigment dispersion syndrome and pigmentary glaucoma patients. The aim of the study is to detect SENSIMED Triggerfish® output signal peak after induced fluctuation by physical exercise or pupil dilation.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. SENSIMED Triggerfish output values

    Patients will undergo 2 sessions of 4 to 6 hours SENSIMED Triggerfish continuous intraocular pressure monitoring in a selected eye, during and/or after physical exercise and pupile dilation

    Measured: during 4 to 6 hours

  2. Goldmann Applanation Tonometry values

    GAT IOP readings will be done in the other eye at regular intervals during 4 to 6 hours SENSIMED Triggerfish IOP monitoring

    Measured: During 4 to 6 hours

Timeline

From the start of the study to its completion; the mark is today. Estimated dates are the sponsor’s plan.

  1. First posted3 Dec 2010 (estimated)
  2. Study startSep 2010
  3. Primary completionNov 2011
  4. Study completionNov 2011

Why it stopped: Law agreement between Triggerfish signal and GAT IOP during both sessions. However, an increase in the Triggerfish signal was observed during jogging phase.

Questions about this trial

What is this clinical trial studying?

An observational study of Pigmentary Dispersion Syndrome and Pigmentary Glaucoma Patients, run by Sensimed AG at 1 site in Switzerland.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 24 Jan 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Switzerland. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was stopped early (reason given: Law agreement between Triggerfish signal and GAT IOP during both sessions. However, an increase in the Triggerfish signal was observed during jogging phase.). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

SENSIMED Triggerfish output values (time frame: during 4 to 6 hours). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Jan 2012.
