Eye movements in children with the Dandy-Walker syndrome

Abstract

Although the effects of cerebellar lesions upon eye movements are well established, there has been no systematic attempt to define the defects of ocular motility that occur in the Dandy-Walker syndrome. The authors have studied the eye movements of four children with this syndrome; all had been treated successfully with ventricular shunts and none had any visual symptoms. Only one of the four patients showed an abnormality: a minor degree of saccadic dysmetria. These findings contrast with the deficits of ocular motility that occur when Dandy-Walker syndrome or other cerebellar disease presents later in life.
