Temporary tarsorrhaphy induced with type A botulinum toxin.

We describe two children with corneal epithelial defects resistant to healing in whom protective temporary ptosis was induced with type A botulinum toxin injected to the levator palpebrae superioris. Epithelial healing was rapid, and no complications were noted. With further study this procedure may become useful in the treatment of corneal epithelial defects resistant to healing.
