Summary
Flash visual evoked potential (FVEP) monitoring is feasible and reliable for assessing visual function during orbital surgery, helping to detect optic nerve injury and reduce surgical errors.
Area of Science:
- Ophthalmology
- Neuroscience
Context:
- Orbital surgery presents challenges in monitoring visual function.
- Maintaining optic nerve integrity is crucial during these procedures.
Purpose:
- To assess the feasibility and reliability of using flash visual evoked potential (FVEP) for intraoperative visual function monitoring.
- To compare intraoperative visual function (IOVF) with postoperative visual function (POVF) using FVEP.
Summary:
- FVEP monitoring was successfully performed in 69 out of 82 cases during orbital surgery.
- A high degree of agreement between IOVF and POVF was observed (67 cases), with minimal false positives (1) and false negatives (1).
Impact:
- Intraoperative FVEP monitoring effectively identifies optic nerve damage and procedural issues.
- This technique can significantly decrease the rate of surgical blindness associated with orbital procedures.
