ClinConnect Summary

This clinical trial is studying how eye pressure changes in patients having a type of back surgery called laminectomy, where the patient lies face down (prone position) during the procedure. Sometimes, being in this position can increase pressure inside the eye, which is rare but could potentially cause serious problems like vision loss after surgery. The study will use a special, gentle device that measures eye pressure without touching the eye, to see how the pressure changes during surgery and to understand what factors, like anesthesia or patient characteristics, might affect these changes.

People who might be eligible to join are adults scheduled for laminectomy surgery under general anesthesia, who are generally healthy enough for surgery (rated ASA I to III), do not have eye diseases like glaucoma, and can cooperate after the surgery. Participants will have their eye pressure measured several times during the surgery using the non-contact device. This information will help doctors find better ways to manage anesthesia and positioning during surgery to keep patients’ eyes safe. If you fit these criteria and agree to take part, the study team will closely monitor your eye health as part of your care.
