About

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.

Trial design

3 participants in 2 patient groups

EEG Electrode Patch

Description:

The additional electrodes are modified EEG electrodes (used in clinical practice on the head already) placed in a silicone molding. These are placed lateral to the eye with the patient asleep. These are then wired to the same recording apparatus that is commonly used for recording.

Treatment:

Device: EEG Electrode Patch

Standard Needles

Description:

The current solution to monitor eye movement during surgery is to place standard needles in the muscles surrounding the eye.

Treatment:

Device: Standard Needles
