Eye ultrasound may replace needle for brain pressure checks
NCT ID NCT07286396
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study will test if a simple eye ultrasound can measure brain pressure in 60 adults before and after brain tumor surgery. The ultrasound looks at the optic nerve sheath diameter, which may change with pressure. If it works, it could offer a safer, non-invasive alternative to current methods.
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 provide a simple, non-invasive way to monitor brain pressure in brain tumor patients, reducing the need for invasive procedures.
- What could go wrong
- This is a small, early observational study (60 people) that only tests a measurement technique, not a treatment. The method may not be accurate enough for routine clinical use.
