Glaucoma study: XyCAM with oxygen
Official title Ocular Blood Flow Imaging for Glaucoma Assessment
ClinicalTrials.gov ID: NCT05726058
What this study is testing
- What it's testing
- The study wants to find out if the XyCAM imaging system can tell the difference between eyes with early glaucoma and healthy eyes, and if it can take pictures and measure blood flow at the same time.
- Who it's for
- People who have early glaucoma or are healthy controls matched for age and other factors.
- What's involved
- Participants will have their blood pressure, heart rate, height, and weight measured, their pupils dilated with a drop, and then be scanned with the XyCAM device, a fundus camera, an optical coherence tomography machine, and a standard eye‑field test while breathing 100% oxygen through a mask.
- Time commitment
- The visit lasts about an hour and includes several eye tests and measurements, with no follow‑up visits required.
