Computer Analysis of Spontaneous Nystagmus

Abstract

By principal component analysis, the difference between irritative nystagmus and paralytic nystagmus was clarified. In irritative nystagmus, slow phase factors together with fast phase factors were highly extracted at the first principal component. In paralytic nystagmus, slow phase factors were mainly extracted at the third and the fourth principal component. As a result, determination of the affected side in peripheral vestibular disorders is possible.
