    摘要： A housing (1) has a hollow section (3), and openings (2a,2b) are formed at both ends of the hollow section so as to communicate with the outside. An aperture is formed in the internal wall of the housing so as to oppose the opening, and a video camera (4) is fitted into the opening. A half mirror (5), a mirror (6), an optical lens (7), and light sources (8a,8b) are disposed within the hollow section (3). The light sources (8a,8b) are alternately illuminated while a patient wears equipment having such a construction. Light reflected from one eye passes through the half mirror (5) and enters a light receiving surface of the video camera (4). On the other hand, light reflected from the other eye is reflected from the mirror (6) and the half mirror (5) and, then, enters the light receiving surface of the video camera (4). The optical lens (7) corrects an error arising from a difference in length between the two optical paths.
