“…1), can be clearly distinguished from opsoclonus and lightning eye movements; the latter are saccadic oscillations induced by upward gaze and characterized by a brief stationary period between successive jerks. In accordance with previous reports [4,9], ocular flutter was associated with flutter dysmetria, square-wave jerks and square-wave oscillations in our patients. Ellenberger [4] reported two cases of associated opsoclonus and ocular flutter, suggesting that these abnormal oscillations are related to each other.…”

We report on three patients who presented a rare, uniform clinical syndrome consisting of ocular flutter and truncal ataxia. In all patients the symptoms followed an upper respiratory infection and resolved without sequelae within a few weeks. Previous reports have emphasized the apparent relationship of this entity to infectious disease, but the infectious agent remained uncertain. In one patient we could find a significant rise in antibody titres to enterovirus. We are not aware of any other similar documented case.

“…DSP usually followed each other with a latency of 150-200 ms. Previously, one report described multiple DSP intermixed with square wave jerks, ocular flutter, and MSO in a patient with presumed MS which might have delayed the circuits controlling saccades and gave rise to saccadic oscillation [12]. However, no responsible lesion was defined in that patient.…”

“…All of these abnormali ties (except for the possible slowing of saccades), as well as the VH (Thurston et al, 1987;Verhagen et al, 1992;Huygen et al, 1994), can be localized to the (vestibulo)cerebellum (including the vermis cerebelli) (Doslak et al, 1983;Sharpe and Fletcher, 1984;Leigh and Zee, 1991). MRI of case 1 revealed mild cerebellar atro phy.…”

Neurological, auditory, vestibular and ocular motor examinations were performed on 3 definite and 3 p o ssib le h e t e r o z y g o u s carriers oi a previously described X-linked multi-system disorder with early childhood onset, rapid progression and a fa t a l o u tc o m e (A rts el al., 1993), The symptoms, i.e., delayed motor development, ataxia, hearing loss and subnormal intelligence, w e r e so e v id e n t in 2 oi I he possible carriers that they could be redesignated as probable carriers. Other symptoms in the definite and p ro b a b le c a r r ie r s w e re clubfeet, dysarthria, intention tremor and abnormal gait, while their signvs included dysdiadochokinesia, ataxic paraplegia, a b n o r m a l m u scle tendon reflexes and extensor plantar responses. All the symptomatic carriers developed moderate-to-severe se n so rin e u ra l h e a rin g loss wilh normal stapedial reflexes and brain stem auditory evoked potentials (B A E Ps) in those in whom this c o u ld b e e v a lu a te d . Speech discrimination was disproportionally poor unilaterally in one case from whom no B A E P s could be obtained b e c a u s e o f her degree o f hearing loss. Various combinations were found of high gain of the vestibulo-ocular reflex, spontaneous n y s t a g m u s and directional preponderance of vestibularly evoked nystagmus, slowing, hypometria or multi-stepping o f saccades, s a c c a d ic in tru sio n s o f eye movements (macro square wave jerks, double saccadic pulses), impairment of smooth pursuit eye movements a n d o p to k in e tic nystagm us, and failure of visual fixation suppression o f vestibularly evoked nystagmus. Such findings indicate m a jo r in v o lv e m e n t of the (vestibuio)cerebellum and the vermis. M R I in one carrier showed mild cerebellar atrophy.
