Management of Vertical Gaze Palsy in Bilateral Thalamic Infarct

Acute Phase Management

The primary management approach for vertical gaze palsy in bilateral thalamic infarct is urgent neurological evaluation with neuroimaging to confirm the extent of midbrain-thalamic involvement, followed by acute stroke management and supportive care with prism correction for persistent diplopia, as recommended by the American Academy of Neurology 1
Perform urgent MRI brain imaging with high-resolution T2-weighted sequences of the brainstem to confirm bilateral thalamic infarction and assess for associated midbrain involvement, according to the American Heart Association 1, 2
Assess both vertical saccades and smooth pursuit, vestibular eye movements, and horizontal gaze to distinguish supranuclear from nuclear causes, as suggested by the American Academy of Neurology 1

Apply standard acute ischemic stroke management including consideration of thrombolysis if within appropriate time window and no contraindications exist, as recommended by the American College of Emergency Physicians 3
Maintain cerebral perfusion pressure >60 mmHg through volume replacement and/or catecholamines if necessary, according to the American Heart Association 4
Implement general intensive care measures including strict blood glucose control, treatment of hyperthermia, and early enteral nutrition, as suggested by the American Heart Association 4

For patients with symptomatic vertical diplopia, prism correction may be necessary for persistent deficits, as recommended by the American Academy of Ophthalmology 1
Small vertical deviations can be managed with prism glasses, though lateral incomitance may limit successful implementation, according to the American Academy of Ophthalmology 5, 6

Initiate early rehabilitation already in the intensive care unit once the patient is stable, as suggested by the American Heart Association 4
Progressive mobilization should begin after resolution of acute phase and absence of signs of significant intracranial hypertension, according to the American Heart Association 4

Do not assume benign etiology: Vertical gaze palsy is a specific indicator of central pathology requiring immediate investigation, even if the remainder of the neurological examination appears normal, as warned by the American Academy of Neurology 2
Do not delay imaging: High-resolution brainstem imaging is essential as standard CT may miss small thalamic-mesencephalic infarcts, as recommended by the American Academy of Neurology 1, 2
