Bilateral ptosis and changes in state of alertness in thalamic infarction.
Uni- or bilateral supranuclear ptosis is known to be caused by cerebral lesion. The exact anatomical cortical and subcortical basis is still undefined. We report a case of a patient developing bilateral ptosis with a left thalamic lesion. The bilateral ptosis was associated with transient changes in the state of alertness. We postulate that the thalamus, especially the anterior region, may have an influential role on the pathway from the cortex via the posterior branch of the internal capsule to the levator palpebrae superioris nuclei.
