Detailed Description:

Patients enrolled in this study will use the new Travatan compliance monitoring dispenser for 6 weeks. Patients will be informed that some, but not all, patients' compliance will be monitored by the device. Patients are randomly assigned to one of three groups (proportionally in a 2/2/1 ratio):

  1. Fully functional Travatan compliance monitor
  2. Travatan compliance monitor with LCD display and alarms disabled, but compliance monitoring intact
  3. Travatan compliance monitor with LCD display, alarms and compliance monitor disabled.

At end of study, patients fill out questionnaire assessing

  1. Patient opinion regarding device: ease of use of new device; preference vs Travatan use without device, etc
  2. patient's belief as to whether their compliance was monitored or not

Rates of adherence are compared across groups and with regard to patients' reported beliefs as to whether they were monitored.

The design of this study should allow the clinicians to ethically monitor compliance in patients who do and do not believe that they are being monitored. The use of monitoring devices without a functioning display and alarm should lead to some patients believing that they are not being monitored. As patients are told at the outset that they may or may not be monitored, this should be an ethically acceptable design. However, the collected data will allow a preliminary assessment of the impact of the patients' beliefs as to whether they are being monitored on their actual compliance, and hence an additional potential value of the device.
