Vertical Gaze Paralysis; Eye Movement Disorders
Description
A patient is shown with up, down, and leftward gaze palsies as a result of a presumed right-sided high midbrain lesion. (He was encountered prior to the introduction of CT scanning, so that localization could not be verified). He had normal vestibulo-ocular reflexes. In addition, he had a curious torsion of his eyes consequent to eye closure and rightward saccades. The torsion was conjugate so that extorsion of the left eye was accompanied by intorsion of the right eye, and the reverse.
