A concussion screening device includes an illumination unit, an image sensor array, a processing unit, and system memory. The concussion screening device displays stimuli on the illumination unit and receives a plurality of images on the image sensor array. The stimuli correspond to a concussion test. The processor processes the plurality of images, which includes detecting one or more pupils of an evaluated person during the concussion test. Based on the processing, the concussion screening device determines whether or not an evaluated person has suffered a concussion. The results are displayed to a user and/or the evaluated person.
