As long ago as 1978, BOTOX® was used as a treatment for patients with eye squints by weakening the overactive eye muscles. Since then, it has been used in a variety of therapeutic areas such as spasmodic neck, writer’s cramp, tics, multiple sclerosis, facial spasm, Parkinson’s disease and cerebral palsy, to name but a few. In more recent times the use of BOTOX® for cosmetic therapy has become more widespread.
