Eye ultrasound during gallbladder surgery
Part of Brain & nervous system clinical trials.
This study uses a simple ultrasound of the eye to measure eye structures. It aims to see if these measurements can help doctors check for pressure inside the head during your gallbladder surgery.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 80 years old.
- You are scheduled to have your gallbladder removed using minimally invasive (laparoscopic) surgery.
- You are in good general health or have only mild health issues (classified as ASA I or II).
- You have no history of brain masses, high pressure in the head, abdominal trauma, or eye/orbit injuries.

This study tests a non-invasive way to monitor pressure inside the skull during brain tumor surgery. It may help guide treatment without the need for invasive monitors.
This study uses eye scans to see if changes in the retina can help doctors measure pressure inside the skull. It may help find a safer way to check for high pressure in the brain without needing a needle in the back.
This study checks if a simple, painless eye ultrasound can help predict confusion (delirium) after heart surgery. It may help doctors identify patients at risk earlier and improve recovery.
This study uses a safe ultrasound test that looks at the nerve at the back of your eye to check for pressure inside the skull after a head injury. It may help doctors monitor you more easily without more invasive procedures.
This study uses a special ultrasound on the eye to measure the optic nerve sheath, which can help detect increased pressure in the brain without needing an invasive test. It aims to provide a rapid, bedside method to identify patients who need urgent treatment.
This trial uses a simple eye ultrasound (like the ones used for pregnant women) to check if there is extra pressure in the brain after a head injury. It compares this quick test with a CT scan (the standard X-ray picture) to see if it can safely help doctors decide on treatment faster.
