    Abstract:
    After introducing the problem of blepharospasm, we report our experience on treatment with purified botulinum A toxin in 16 cases of blepharospasm, symptomatic in two and essential in 14, than had not responded to drugs. The changes in intensity and frequency of spasm after treatment were evaluated on a clinical scale and by review of videotapes. The beneficial effect appeared within a week in most patients, lasting from 6 to 28 weeks (mean 13), and reached the maximum at the third-seventh week. Mild spasms and female patients responded better. Repeated injections were followed by better response to the drug. Complications, exclusively local, were represented by transient corneal exposure, ptosis, lacrimation or diplopia.
