Acute ectropion following botulinum toxin injections for the treatment of blepharospasm after bilateral facial neurectomies

Abstract

Botulinum toxin A has become the accepted standard treatment for facial dystonia, e.g., blepharospasm and oromandibular spasm^1–4. Side effects are infrequent and if they occur they are mild, usually limited to lacrimation, dry eye syndrome or ptosis. Tearing, dry eyes and ptosis are among the most often reported^5–7. The author reports a case of acute ectropion after botulinum toxin A injections in a patient with blepharospasm who underwent previous bilateral facial neurectomy.
