Vestibular stimulation for supranuclear gaze palsy: case report
Archives of Physical Medicine and Rehabilitation
|March 1, 1983
Summary
Gaze palsies from cerebral lesions are rare. Cold caloric vestibular stimulation rapidly resolved a patient's supranuclear ophthalmoplegia, restoring eye movements for over a year.
Area of Science:
- Neurology
- Neuroscience
- Ophthalmology
Background:
- Gaze palsies resulting from severe cerebral hemisphere lesions are uncommon.
- Supranuclear ophthalmoplegia can occur secondary to stroke, impacting voluntary eye movements.
Observation:
- A patient presented with fixed rightward gaze deviation 3 months post-right cerebral hemisphere infarction.
- Cold caloric vestibular stimulation was administered to assess brainstem integrity.
Findings:
- Following three cold water injections, the patient regained full voluntary extraocular eye movements.
- This improvement persisted for over 12 months post-treatment.
Implications:
- Vestibular stimulation may offer a therapeutic intervention for certain types of gaze palsies.
- Vestibular input might modulate extraocular muscle activity, explaining the observed recovery.
