Does anesthesia flow affect eye pressure? new study investigates

This study looked at 80 adults having open gynecologic surgery to see if the amount of anesthesia gas affects the size of the nerve at the back of the eye. Researchers measured the optic nerve sheath using ultrasound before and during surgery with either minimal or high gas flow. The goal was to understand how different anesthesia techniques might influence eye pressure, but this was an observational study, not a treatment.
