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.
A man who had suffered from Eales disease at the age of 20 presented an acute Brown-Séquard spinal syndrome when he was 30, followed shortly after by paralysis of the right abducens and recurrent laryngeal nerves. Steroid treatment apparently relieved the myelopathy while the neurological deficits have remained unchanged for the past 14 years. In view of the clinical and CSF findings the neurological deficits are attributed to the same disease process as that underlying the peripheral retinal abnormalities characteristic of Eales disease rather than to multiple sclerosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
