This study is looking at a new way to assess glaucoma using a special imaging device called XyCAM RI and XyCAM FC. Researchers want to see if this device can measure blood flow in your eyes to tell the difference between healthy eyes and eyes with early-stage glaucoma. They also want to confirm that the XyCAM FC can take both regular pictures of your eye and measure blood flow at the same time. You might be able to join if you are 18 to 88 years old, have healthy vision, are being checked for glaucoma, or have moderate to severe glaucoma. The study involves imaging your eyes and inhaling 100% oxygen during some imaging. The main goal is to measure blood flow velocity in your eyes over about one year.

Study design

This is an interventional study planning to enroll 150 participants. It is not specified if it is randomized or blinded.

What's involved

You will have your blood pressure, heart rate, height, and weight measured, and your pupils will be dilated with eye drops (tropicamide). You will undergo several eye imaging tests, including some while inhaling 100% oxygen. The imaging sessions will take about 80 minutes, with an additional 60 minutes for other procedures.

Compensation

Not stated in the trial record.

Follow-up

Blood flow velocity will be measured through study completion, which is an average of 1 year.
