Continuous Intraocular Pressure (IOP) Monitoring in Pigmentary Dispersion Syndrome and Pigmentary Glaucoma Patients

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01253109
Recruitment Status : Terminated (Law agreement between Triggerfish signal and GAT IOP during both sessions. However, an increase in the Triggerfish signal was observed during jogging phase.)

Brief Summary:
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.

SENSIMED Triggerfish Device: SENSIMED Triggerfish
Contact lens-based device for continuous IOP monitoring

Primary Outcome Measures :
  1. SENSIMED Triggerfish output values [ Time Frame: during 4 to 6 hours ]
    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

  2. Goldmann Applanation Tonometry values [ Time Frame: During 4 to 6 hours ]
    GAT IOP readings will be done in the other eye at regular intervals during 4 to 6 hours SENSIMED Triggerfish IOP monitoring
