Treatment of blepharospasm, hemifacial spasm and strabismus with botulinum a toxin

Thirty patients with blepharospasm, hemifacial spasm, strabismus and entropion were treated with botulinum A toxin giving satisfactory results. Rapid spasm relief, correction of strabismus and entropion were obtained. Only mild, transient and local side-effects occurred. The patients were followed up for 4-12 weeks with no recurrence. The clinical results show that local injection of a minute dose of botulinum A toxin in treating blepharospasm, hemifacial spasm, strabismus and entropion is a safe, effective and simple method of nonsurgical therapy.
