Of those patients seeking surgical correction for intractable blepharopasm, the spasm was more commonly bilateral than unilateral by a ratio of about 7:1 and the bilateral form was more common in women than men by a ratio of about 3:1. The unilateral disease had an equal sex incidence. The disease seemed to be the same in men and women. The median age of onset was 59 years old, and the median interval between onset of symptoms and surgery was three years. Most of these patients had seen many physicians, and all prior medical and surgical treatments had been unsuccessful.
