The following report describes a patient who illustrated the interesting phenomenon of involuntary closure of one eye when opening the mouth. This phenomenon was described by Marin Amat1 in a patient with a peripheral facial paresis and is sometimes referred to as the Marin Amat syndrome or inverted Marcus Gunn phenomenon. Wartenberg2 critically reviewed previously reported cases and concluded that the syndrome appears to follow an infranuclear paralysis of the facial nerve. The inverted or reverse Marcus Gunn phenomenon as defined by Wartenberg6 is represented by an involuntary movement of the jaw to the opposite side when the cornea is touched. He believed this to be a release phenomenon associated with a supranuclear lesion of the trigeminal nerve.

Our case presented a history suggestive of recurrent vertebral basilar artery insufficiency but not the usual history of a Bell's palsy.
