13 patients with hemifacial spasm and 19 patients with blepharospasm (essential blepharospasm or Meige syndrome) were treated with injection of botulinum A toxin in the eyelids. The effectiveness of this therapy is constant and the treatment offers relief to almost all patients. The response times for repeated treatment was 6 months for blepharospasm and 7 months for hemifacial spasm. Repeated injections were performed in several patients and gave the same improvement. Transient ptosis or diplopia were observed in 11 patients. Possible systemic side effects (respiratory trouble) were documented in two patients. Botulinum toxin injection is an effective treatment but the relief is usually temporary and repeated treatments are necessary.

D001905	Botulinum Toxins	Toxic proteins produced from the species CLOSTRIDIUM BOTULINUM. The toxins are synthesized as a single peptide chain which is processed into a mature protein consisting of a heavy chain and light chain joined via a disulfide bond. The botulinum toxin light chain is a zinc-dependent protease which is released from the heavy chain upon ENDOCYTOSIS into PRESYNAPTIC NERVE ENDINGS. Once inside the cell the botulinum toxin light chain cleaves specific SNARE proteins which are essential for secretion of ACETYLCHOLINE by SYNAPTIC VESICLES. This inhibition of acetylcholine release results in muscular PARALYSIS.
