Effect of surgery position on eye nerve sheath size
Part of Brain & nervous system clinical trials.
This study is for people having kidney stone surgery. It looks at how the position you are in during surgery affects the nerve sheath around your eye, which may help doctors monitor pressure in the brain.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are scheduled to have a type of kidney stone surgery called retrograde intrarenal surgery.
- You are between 18 and 65 years old.
- You are generally healthy or have only mild health problems (classified as ASA I or II).
- You are fully awake, alert, and able to follow instructions.
- You have not had brain surgery or eye surgery before.
- Your body mass index (BMI) is 30 or less.

This study looks at how different air pressure levels in the belly during laparoscopic (keyhole) gynecologic cancer surgery might affect the nerve at the back of the eye. Researchers measure the optic nerve sheath to see if pressure changes cause swelling.
This study uses a simple eye ultrasound to measure eye structures during gallbladder surgery. It aims to see if these measurements can help monitor pressure inside the head during the procedure.
This trial tests a non-invasive way to measure pressure inside the skull during brain tumor surgery. If it works, patients may avoid more invasive pressure monitors.
This study uses a painless ultrasound to measure the nerve behind your eye in pregnant women with preeclampsia. The goal is to see if this measurement can help doctors better manage anesthesia during delivery.
This study examines how the menstrual cycle may affect pressure in the optic nerve (the nerve connected to your eye) during laparoscopic gynecologic surgery. Researchers want to understand if the timing of surgery within your cycle matters for eye and brain safety.
This trial compares two ways of giving lidocaine (a numbing medicine) to see which better prevents a rise in pressure around the eye after a breathing tube is placed. It may help patients having planned surgery who are at low risk for eye or brain problems.
