NCT ID NCT04600570
First seen Jul 20, 2026 · Last updated Jul 21, 2026 · Updated 1 time
Summary
This study uses ultrasound to measure the diameter of the optic nerve sheath in healthy Taiwanese adults aged 20 and older. The goal is to establish normal reference values and identify factors like age or body size that may influence these measurements. The findings could help doctors better diagnose conditions that increase pressure inside the skull.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
