Botox - Approved Indications    

 

Eye and Facial Spasms

The term blepharospasm can be applied to any abnormal uncontrolled muscle contraction around the eyes, from blinking or eyelid tics to twitches and the inability to keep the eyes open for significant periods of time.

Long-term studies have shown that up to 90% of patients with blepharospasm obtain almost complete relief lasting 3 to 4 months after Botox® injections (Carruthers 1985; Carruthers 1987; Scott 1985; Tsoy 1985; Dutton 1986; Dutton 1994; Poungvarin 1997).

Hemifacial spasm is a disorder characterized by frequent involuntary contractions of the muscles on one side of the face. Hemifacial spasm is treated primarily with Botox® injections, with up to 95% of people with involuntary facial spasms and tics reporting improvement after treatment (Wang 1998). There is evidence that repeated injections over a longer period of time may increase the benefit (Jankovic 1993).
