Clostridium botulinum bacteria produce eight serotypes of botulinum toxin proteins (A, B, Ca, Cb, D, E, F, and G). Botulinum toxin serotype A is the most potent and is used for functional and cosmetic indications all over the body. There are some specific functional indications for Btx A injections in oculoplasty. Understanding those indications will help the general ophthalmologist to counsel their outdoor patients. Giving Btx A injections require knowledge of facial anatomy. Oculoplasty surgeons are trained to give Btx A injections.
