Spine surgery study: ventilator pressure may change eye nerve size
Knowledge-focused CompletedThis study looked at 105 adults having spine surgery to see if different ventilator pressure levels (5 vs 10 cmH2O) change the size of the optic nerve sheath, which can indicate pressure inside the brain. The goal was to understand how breathing machine settings might affect the …

Anesthetic showdown: which drug keeps eye pressure safer during surgery?
Knowledge-focused CompletedThis study looked at how two different anesthesia drugs—desflurane and propofol—affect the size of the optic nerve sheath (a measure of pressure around the eye) in 146 adults having gallbladder surgery. The goal was to see if one drug caused less pressure change than the other. R…
