Also known as nystagmus. A condition in which the eyes move rhythmically. Depending on the direction, there are horizontal, vertical, rotational, and other types. Physiologically, it can occur when tracking a rapidly moving object or making vigorous rotational movements. Pathologically, it can occur due to disorders or diseases of the visual organs, labyrinth, brain, or related central nervous system. In this case, it may not be rhythmic, and is often accompanied by dizziness. Source : Heibonsha Encyclopedia About MyPedia Information |
