Eye ultrasound may spot spinal headache risk

NCT ID NCT07100158

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tested whether measuring the optic nerve sheath with ultrasound can predict postdural puncture headache (PDPH) after spinal anesthesia. 176 adults having knee replacement surgery were scanned before and after the procedure. The goal was to see if changes in nerve sheath diameter could identify who would develop a headache that worsens when sitting or standing.

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 give doctors a simple, non-invasive way to predict and monitor postdural puncture headache after spinal anesthesia.
What could go wrong
This is a completed diagnostic study, not a treatment trial. The findings may not apply to all patients or settings, and the measurement technique requires training.
