Chemodervation with abobotulinum toxin A (Dysport) and botulinum toxin type A (Botox) is finding an expanding role in functional and cosmetic cases. We describe the use of chemodenervation with abobotulinum toxin A for functional corneal protection in two cases and botulinum toxin type A for facial symmetry after Bell's palsy in one patient. The first case is a 75-year-old female with a nonhealing corneal erosion in her right eye secondary to epithelial basement membrane corneal dystrophy who underwent injection of 24 units of abobotulinum toxin A to the right Muller's muscle and levator palpebrae superioris to induce a protective ptosis. The second case is a 40-year-old male with corneal decompensation in the right eye after penetrating keratoplasty who underwent similar injection at both sites. The third case is a 46-year-old Asian female with history of Bell's palsty affecting her right side and causing mild left eyelid retraction who was injected 3 units of botulinum toxin type A to her Muller's muscle for lid positioning. Chemodenervation is used in these cases to purposefully induce ptosis by careful injection to Muller's muscle and the levator palpebrae superioris for functional and cosmetic purposes.
