Combined up- and downgaze palsy associated temporarily with a unilateral midbrain infarction.
and reactive normally to light, associated with subtle left eyelid ptosis. Five days later, his diplopia had resolved. On voluntary vertical gaze, trace upward and downward movement returned. Oculocephalic maneuver elicited downward saccade but failed to hold the downward gaze, and elicited no upward gaze ( fig. 1 A). Vertical saccades and pursuit returned normal on follow-up examination 2 week...
متن کاملIsolated nuclear oculomotor nerve syndrome due to mesencephalic hematoma.
Unilateral third nerve palsy with bilateral superior rectus paresis and bilateral ptosis is a typical condition for nuclear oculomotor nerve syndrome. We report a case of nuclear oculomotor nerve syndrome due to midbrain hemorrhage, as a rare cause. A 73-year-old man presented with an abrupt onset of double vision and difficulty opening his eyes. He had uncontrolled hypertension in his history....
متن کاملUnilateral thalamic infarction presenting as vertical gaze palsy: a case report
INTRODUCTION Vertical gaze palsy is a recognized manifestation of midbrain lesions. It rarely is a consequence of unilateral thalamic infarction. CASE PRESENTATION We report the case of a 48-year-old African-American woman who presented to our facility with vertical gaze palsy and evidence of left medial thalamic infarct on diffusion-weighted imaging without coexisting midbrain ischemia. The ...
متن کاملMonocular elevation paresis and contralateral downgaze paresis from unilateral mesodiencephalic infarction.
A 26 year old woman presented with monocular elevation paresis of the right eye, contralateral paresis of downward gaze, and subtle bilateral ptosis. Magnetic resonance imaging disclosed a unilateral embolic infarction restricted to the mesodiencephalic junction involving the left paramedian thalamus. Preserved vertical oculocephalic movements and intact Bell's phenomenon suggested a supranucle...
متن کاملEyebrow Ptosis After Blowout Fracture Indicates Impairment of Trigeminal Proprioceptive Evocation That Induces Reflex Contraction of the Frontalis Muscle
OBJECTIVE The mixed levator and frontalis muscles lack the interior muscle spindles normally required to induce involuntary contraction of their slow-twitch fibers. To involuntarily move the eyelid and eyebrow, voluntary contraction of the levator nonskeletal fast-twitch muscle fibers stretches the mechanoreceptors in Müller's muscle to evoke trigeminal proprioception, which then induces reflex...
