The type of bilateral blepharospasm to be discussed in
this paper is a disease usually occurring in persons over the age of forty. It has been named bilateral facial spasm (Parker),1spasme facial median (Meige),2 and paraspasme facial bilatéral (Sicard).3 It is of unknown etiology but may be associated with Parkinson's disease (Parker).1 From the history in many patients it would appear to have a large psychosomatic component, although it has not been proven that this is the cause of the disease.
The condition may occur in a relatively mild form in which patients have intermittent bilateral spasmotic closure of the lids occurring a few times a minute or at a greater or lesser interval. They are able to control the eyelids enough so that vision is possible. Although the symptoms are annoying, they are not disabling, and the afflicted can go about their usual business.
