ISOLATED EYELID-OPENING APRAXIA - REPORT OF A NEW LEVODOPA-RESPONSIVESYNDROME

Eyelid-opening apraxia (or involuntary levator inhibition) has been de scribed chiefly in the context of basal ganglia disease. We present tw o novel cases in which apraxia of eyelid opening developed in the abse nce of any other CNS signs, and which resolved following treatment wit h levodopa. We suggest that when inability to open the eyes occurs wit hout associated motor impairment, ''apraxia'' is the correct descripti ve term, and a trial of levodopa should be considered.
