Abstract

Simultaneous contraction of various muscles with levator palpebrae have been reported as a phenomenon of the paradoxic synkinesis. The authors observed an unilateral eyelid retraction induced by the postural change from supine to sitting position in a 33-month-old girl and a 4-year-old boy. In both cases, the levator function of both eyes was normal and ptosis was not observed. These cases were presumed to be related with postural righting reflex, but the exact neurological basis is not fully defined yet.
