Eyelid motor abnormalities found in progressive supranuclear palsy are reviewed. Electrophysiological correlates of blepharospasm, levator inhibition (blepharokolysis) and supranuclear paralysis of lid closure are presented. Disorders of eyelid motility are not uncommon in progressive supranuclear palsy (PSP). They may be found in about one third of patients with this syndrome (Jackson et al., 1983; Golbe et al., 1989). This is not surprising since ocular and eyelid movements are highly coordinated, mainly in the vertical plane (Gordon, 1951; Kennard and Smith, 1963; Kennard and Glaser, 1964), and a supranuclear ophthalmoplegia with down gaze impairment is a cardinal feature of PSP (Steele et al., 1964). The spectrum of eyelid motor disorders described in PSP includes blinking abnormalities, lid retraction, blepharospasm, levator inhibition and supranuclear palsy of eye closure.
