Eye ultrasound may help monitor brain pressure during heart surgery
NCT ID NCT07253922
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether ultrasound measurements of the optic nerve sheath (the lining around the eye nerve) can detect changes in brain pressure during open-heart surgery when patients are on a heart-lung machine. Researchers measured the optic nerve sheath diameter in 40 adults at several points during surgery. The goal was to see if this simple, non-invasive technique could help monitor brain pressure when direct measurement isn't possible.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
What this could lead to
If successful, this could lead to a non-invasive way to monitor brain pressure during heart surgery, potentially improving patient safety.
What could go wrong
This is a small, completed observational study with only 40 participants. It does not test a treatment, and the method needs much larger studies to confirm it works reliably.
