Intraoperative Non-invasive Eye Movement Monitoring

Completed
Conditions
Surgery
Registration Number
NCT03046615
Lead Sponsor
Mayo Clinic
Brief Summary

For procedures involving proximity to the nerves responsible for eye movement, the need to monitor eye movement exists. The current solution is to place needles in the muscles surrounding the eye. The Investigators have invented a non-invasive electrode and software designed to monitor eye movements non-invasively. The electrode is placed on the skin on the corner of the eye and using the natural dipole of the eye, detects the horizontal and vertical movements of the eye. The Investigators would like to prove efficacy compared to the standard monitoring.

The current method of measuring eye movement is to place needles in the muscles surrounding the eye. For the non-invasive method, the electrode is placed on the skin on the corner of the eye and using the natural dipole of the eye, detects horizontal and vertical movements of the eye. The signal comparison for the two methods would be a biphasic dipole representing eye movements compared to the compound muscle action potential of the invasive method.
