[Clinical study of disorders of eye movements (voluntary and following) after acute vascular accidents involving the cerebral hemispheres (author's transl)].

Voluntary eye movements and following movements have been assessed on a 3 point scale in 33 cerebrovascular patients, examined immediately after the stroke and in 52 patients examined 6-9 days after the stroke. The two types of movements were found to be impaired to the same extent in the majority of patients, especially those with severe neurological deficits. The "agreement index" between them, though high, was significantly inferior to 1. This suggests that voluntary and following movements are subserved by adjacent, but not identical neuronal structures. The available neuro-radiological evidence points to the parieto-temporal cortex as the area critically involved in eye movement disorders.
