[Flutter-opsoclonus: report on three cases (author's transl)].

Three cases of spontaneous saccadic ocular movements are reported, each with one or several electrooculographic recordings. Case 1 is a typical ocular flutter during a myoclonic encephalitis with cerebellar signs. Case 2 is an ocular flutter occurring in the course of an acute inflammatory polyneuropathy with cerebellar signs after cytomegalovirus infection. Case 3 began with permanent dissociated opsoclonus, then conjugated opsoclonus and ended with vertical flutter in a patient suffering from bronchial carcinoma. While some definitions are unclear, clinical, electrooculographic and etiological data support a unicist point of view on flutter-opsoclonus.
