Outline of Final Research Achievements

Visual evoked potential (VEP) is one of the intraoperative monitoring methods to avoid severe postoperative complications such as loss of vision, and is evoked by applying
flush light stimulus to the patients retina. In this project, a novel VEP pad which is flexible, disposable, and capable of applying complicated lighting patterns was designed with optical simulation using the Monte-Calro method. The fabricated VEP pad showed capability of visual hemifield stimulation and pupil detection even under eyelid closure.
