[Nuclear magnetic resonance study of oculomotor alterations in multiple sclerosis].

The authors employing N.M.R. have studied 18 patients affected by M.S. with oculomotor alterations. In 16 cases a relation between location of the lesions and clinical features has been documented; in 2 cases with subclinical paralysis N.M.R. has not documented macroscopic lesions in the brainstem: the presence of multiple lesions in the cerebral white matter however is indicative of supranuclear centers involvement.
