| Abstract |
|
We studied the safety and complication associated with treatment with botulinum A toxin chemodenervation. 70 eyes was entrolled and treated with botulinum A toxin chemodenervation. They were examed at 1 day, 1 week, 2 weeks, 1 month, 3 months and 6 months after the injection. Ptosis developed in 19 of 70 eyes(27.1%), but all of them recovered fully at 6 months after injection. A vertical deviation was noted in 19 eyes(27.1%), but all except one recovered fully at 6 months. Ptosis and vertical deviation developed more frequently in the group with the medial rectus muscle injection than with lateral rectus muscle injection. Subconjunctival he.morrhage and headache were also noted in 1 eye, respectively, but they disappeared at 4 weeks after the injection. Aggrevation of diplopia after injection was noted in 1 eye, which disappeared at 3 weeks after injection. Botulinum A toxin chemodenervation can be considered to be a safe method for the treatment of strabismus without the long-lasting serious complications. |
