Abstract
Intraoperative monitoring of visually evoked potentials (VEPs) is sometimes unachievable because of light axis misalignments caused by frontal scalp-flap reflection and intraoperative manipulation. Here, we present a new method of intraoperative VEP monitoring that involves a sterilised photostimulation device that can be adjusted in position following disturbances from frontal scalp-flap reflection or intraoperative manipulation.
