[Alternating oblique deviation of the gaze. 3 cases].
Three cases of alternating skew deviation of gaze are reported. In two patients, it was associated with oculomotor disorders suggestive of a medial mesencephalic lesion. CT scan showed 3rd ventricule abnormalities accounting for the mesencephalic involvement. The third patient had a tuberculous meningo-encephalitis with basal symptoms. The pathophysiological mechanisms of the vertical interocular divergence is discussed. It was probably related to a bilateral disorder of the superior recti and an overaction of the inferior obliques. It suggested a medial supranuclear dysfunction.
