Abstract
A device for monitoring eye movement and pupil response that comprises a first optical pathway for displaying one or more images to the eyes of a patient and a second optical pathway for obtaining images of the eyes of a patient. The device further comprises at least one screen for displaying an image to the left eye of the patient which is not visible to the right eye of the patient and for displaying an image to the right eye of the patient which is not visible to the left eye of the patient; a first camera for capturing images of the left eye of the patient; and a second camera for capturing images of the right eye of the patient at substantially the same time as the first camera is capturing images of the left eye of the patient. The device also comprises at least one IR light source for illuminating the eyes of the patient; and a processor for processing the obtained images and measuring pupil response and/or eye movements.
