Periodic saccadic oscillations and tinnitus.
A man with essential hypertension developed stereotyped cycles of oscillopsia and bilateral "sparking" tinnitus. Eye movement recordings showed cycles of disconjugate opsoclonus, square-wave jerks, and saccadic dynamic overshoot disrupting stable fixation. Neuroimaging studies were normal. We postulate a lesion episodically disturbing saccade-related neurons and central auditory neurons in the pons.
