ClinConnect Summary

This clinical trial is looking at how two types of anesthesia, desflurane and propofol, affect vision in patients who are lying on their stomachs during spinal surgery. The researchers want to understand if one of these anesthetics might be better at keeping eye pressure lower, which could help preserve vision quality after surgery.

To participate in this study, you would need to be between the ages of 18 and 75 and have a good level of alertness, as indicated by a score of 15 on the Glasgow Coma Scale. You should also be in good overall health, as defined by a classification system used by anesthesiologists. Participants should be undergoing spinal surgery that lasts less than three hours and should have a normal heart rhythm. However, if you have a serious neurological condition, lung disease, or a known allergy to propofol, you would not be eligible for this trial. The study is not yet recruiting participants, but it's designed to help improve our understanding of how anesthesia can affect vision during surgery.
