The pilot study of alteration of retinal nerve fiber layer thickness in Thai patients whom underwent spinal surgery by optical coherence tomography (OCT)
Completed
- Conditions
- Patients undergo spine surgery in prone position.spine surgery, prone
- Registration Number
- TCTR20231031002
- Lead Sponsor
- /A
- Brief Summary
In summary, our findings reveal a decrease in RNFL thickness in the inferior quadrant at the 6-week follow-up after spine surgery. The prone position during surgery may play a significant role in the development of postoperative posterior ischemic optic neuropathy (PION) in patients undergoing spine surgery in this position.
