Abstract
- Apraxia of eyelid opening is nonparalytic inability to open the eyes at will in the absence of visible contraction of the orbicularis oculi muscle. It is known that apraxia of eyelid opening is a feature of extrapyramidal diseases. We experienced a case with apraxia of eyelid opening after right thalamic infaction. We suggest that dysfunction of supranuclear control of the levator palpebrae superioris may be a pathophysiologic mechanism in apraxia of eyelid opening.
