Botox is a prescription medicine that has a number of uses, including the treatment of blepharospasm (involuntary eye twitching) and hemifacial spasm (spasms around the eye area).
What Is Botox?
Therapeutic botulinum toxin, known as Botox, is the most effective treatment for blepharospasm and hemifacial spasm. A drop of Botox is injected under the skin at affected sites on both sides of the face. Over the next few days, the injections begin to relax and weaken the little muscles just under the skin and prevent spasms. Most neuro-ophthalmologists and some neurologists perform Botox injections. The Botox procedure is done in the doctor’s office and usually takes 10 to 15 minutes. The effect wears off in about three months, after which the injections must be repeated. Most patients have no side effects from the injections, but some minor bruising can occur at the injection sites. Temporary eyelid drooping and double vision may occasionally occur.
