Carbon dioxide pressure and eye nerve sheath in kidney surgery
Part of Eyes & vision, Kidney & urinary clinical trials.
This study looks at how the carbon dioxide gas used during keyhole kidney cancer surgery affects the pressure behind your eye. The goal is to see if changes in gas pressure influence the nerve sheath that surrounds the optic nerve.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 31 and 69 years old.
- You have been diagnosed with kidney cancer and are scheduled for a laparoscopic (keyhole) surgery to remove part or all of your kidney.
- You do not have any eye injury, severe swelling around the eye, or other eye problems that would block a measurement behind your eye.
- You can safely lie on your side (45-degree angle) for surgery without problems like severe scoliosis, breathing issues, or spine instability.
- You do not have any known brain condition (such as a tumor, fluid buildup, or recent head injury) that would increase pressure inside your skull.

This trial compares two types of needles used for spinal anesthesia to see if one type causes less pressure change around the optic nerve. If you are having lower leg or knee surgery with a tourniquet and are generally healthy, this study may be for you.
This study looks at how the steep head-down position (Trendelenburg) and gas inflation during robot-assisted prostate surgery affect the sheath around the optic nerve. It aims to understand eye pressure changes to improve safety.
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 study compares two types of breathing tubes used during general anesthesia in children to see how they affect the size of the optic nerve sheath, which can indicate pressure changes in the brain.
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.
This trial checks if measuring the nerve sheath in your eye can help doctors predict brain-related problems after carotid artery surgery. It aims to improve safety during the procedure.
