Plain-language summary
The device being studied in this research is the investigational PIB, a tool designed to measure eye pressure without touching the eye. The device uses a very low-power, eye-safe infrared light and a gentle sound signal to detect tiny movements on the white part of the eye. A camera records these movements, and a computer analyzes the information to estimate eye pressure. The test takes only a few seconds and does not require eye drops or contact with the eye. The device rests near your face using a chin and forehead support, like equipment used in an eye doctor's office.
The PIB aims to provide the following possible benefits over the devices doctors may be using now including the GAT:
* No touching of the eye to lower the risk of infection and discomfort
* Improved accuracy and precision
* Faster eye pressure measurements
* Measurements that may be done by a patient at home without the need for a doctor
* A low-cost eye pressure measurement device that may be used in areas where there are fewer doctors
The PIB device is investigational, which means that it is not approved by the Food and Drug Administration (FDA). The GAT device has been approved by the FDA.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
