title: Botulinum A toxin treatment of a deviated orbital implant.
abstract: We report a case of progressive deviation of an implant that resulted in conjunctival thinning and an inadequately fit prosthesis. Such a case may have been treated with conjunctival grafting or replacement of the implant with an hydroxyapatite sphere. In this case, injection of botulinum A toxin (Botox) into the contracted medial rectus muscle contributed to the successful refitting of a new and stable prosthesis and improvement of the conjunctival integrity. Possible explanations of the progressive shift in the position of the implant and its postinjection stability are discussed.
