Outline of Final Research Achievements

By the analysis of abnormal nystagmus using our three-dimensional eye movement analyzing system developed in this study, we made certain that the abnormal nystagmus rotates around the axis perpendicular to the plane of semicircular canal when the cause of disease is peripheral lesion and that the abnormal nystagmus does not rotate around the axis perpendicular to the plane of semicircular canal when the cause of disease is central lesion. By analyzing the rotational axis of abnormal nystagmus it is possible to distinguish the disease with central lesion from the disease with peripheral lesion.
