Could surgery gas pressure harm your eyes? new study investigates
NCT ID NCT07155109
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study looks at how different gas pressures used during laparoscopic surgery for gynecologic cancers affect the optic nerve sheath diameter, which is a marker of pressure inside the skull. Researchers will measure this in 100 women aged 18-65 using ultrasound. The goal is to see if lower gas pressure leads to less pressure on the brain and eyes.
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 help surgeons choose safer pressure settings to reduce the risk of increased brain pressure during laparoscopic surgery.
- What could go wrong
- This is a small, early-stage observational study, not a treatment trial. It measures a surrogate marker (optic nerve diameter) rather than direct patient outcomes, so clinical benefits are uncertain.
