Psychogenic unilateral ptosis with ipsilateral muscle spasm of orbicular oculi.

This report describes the rare case of a 27-year-old female patient with conversion disorder who presented unilateral ptosis with ipsilateral muscle spasm of orbicular oculi. The co-existing of ptosis and muscle spasm of orbicular oculi indicates that, in accord with prior reports, the overactivity of orbicular oculi is essential in psychogenic pseudoptosis. The co-existing of unilateral ptosis and ipsilateral muscle spasm of orbicular oculi in the present case leads us to the conclusion that the overactivity of orbicular oculi is essential in psychogenic pseudoptosis.
