title: Botox® after Botox® - a new approach to treat diplopia secondary to cosmetic botulinic toxin use: case reports.
abstract: A new technique for the treatment of diplopia secondary to cosmetic botulinum toxin A use is described. In this interventional case reports, two consecutive patients who developed diplopia after periocular cosmetic use of botulinum toxin A were treated with intramuscular botulinum toxin A injection into the antagonist extraocular muscle. Diplopia resolved in both patients in less than 1 week with no side effects or complications. In conclusion, the injection of intramuscular botulinum toxin A is an encouraging option for treatment of diplopia secondary to botulinum toxin A use for facial lifting.
