[Ocular diskinesia].

The clinical findings and the electro-oculogram were correlated in four cases (3 postinfectious, 1 vascular) with ocular dyskinesias, of a mixed type in two of them. This correlation led to a more precise recognition of the pattern of opsoclonus, flutter and ocular dysmetria. Ocular dyskinesias have certain resemblances with voluntary saccadic movements; the effects of ocular following and optokinetic stimulation are described. The role of brainstem and cerebellar structures in relation with the physiopathology of these dyskinetic ocular movements is discussed.
