Case Reports[Oculographic findings in the Arnold-Chiari malformation type I].
The paper deals with 5 adults carriers of this syndrome diagnosed by means of nuclear magnetic resonance (NMR). Neither the conventional radiography nor the plain computerized tomography showed indicative clues of the deformity. ⋯ In all cases appeared an altered smooth pursuit and a lack of suppression fixation of the vestibular nystagmus. The AA. emphasize the diagnostic value of the electronystagmography (which tracings could spare several other, sometimes expensive, examinations) and suggest a prompt MRI.
