ABSTRACT:
An apparatus for detecting abnormalities in spatial perception that consists of a first transparent screen in a close-vision field and a second screen seen through the first one and located in a far-vision field of a person being tested. The apparatus is provided with devices for forming images selectively on the first or second screen and with a device for tracking trajectories of the eye pupils while following the images. The method is based on detecting specific irregularities in trajectories of the eye pupils, such as nystagmuses, cut-offs, sudden drops of the gaze, etc., when a person follows the smooth trajectory of a moving image on a selected screen, or when the size and position of the eye pupil change with certain irregularity in response to instantaneous switching of images between the screens without changing the position of the person's head.
