We report on three patients who presented a rare, uniform clinical syn
drome consisting of ocular flutter and truncal ataxia. In all patients
the symptoms followed an upper respiratory infection and resolved wit
hout sequelae within a few weeks. Previous reports have emphasized the
apparent relationship of this entity to infectious disease, but the i
nfectious agent remained uncertain. In one patient we could find a sig
nificant rise in antibody titres to enterovirus. We are not aware of a
ny other similar documented case.
