Prevalence of primary blepharospasm in Sardinia, Italy: a service-based survey.
We performed a service-based epidemiological study of primary blepharospasm in the island of Sardinia (Italy). Due to its favorable geographical location, we are confident we will provide reliable data from patients seeking botulinum toxin treatment. A total of 53 patients were assessed. Prevalence was estimated to be 32.2 per 1 million (95% confidence interval, 23.0-40.8). These results are in line with those obtained in other similar surveys, that is, record-based, and performed in various European regions such as Northern England, the Munich area, as well as the Epidemiologic Study of Dystonia in Europe.
