Department of Ophthalmology, Monmouth Medical Center, Long Branch, New Jersey.

We treated 12 patients who had essential blepharospasm with brow and eyelid injections of botulinum toxin. The eyelid injections were kept constant while varying doses were used in the brow. The duration of the effect of the toxin was longer and the degree of improvement greater in those patients receiving more than 20 U in the brow than in those receiving less than 20 U. However, the degree of improvement in spasm intensity in those patients receiving greater than 20 U was similar. Ptosis occurred in seven patients. No systemic side effects were noted.

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.
