Abstract
Objective: Blepharospasm is a type of dystonia where the diagnosis is often delayed because its varied clinical manifestations are not well recognized. The purpose of this study was to provide a comprehensive picture of its clinical features including presenting features, motor features, and non-motor features. Methods: This was a two-part study. The first part involved a systematic literature review that summarized clinical features for 10,324 cases taken from 41 prior reports. The second part involved a summary of clinical features for 884 cases enrolled in a large multicenter cohort collected by the Dystonia Coalition investigators, along with an analysis of the factors that contribute to the spread of dystonia beyond the periocular region. Results: For cases in the literature and the Dystonia Coalition, blepharospasm emerged in the 50s and was more frequent in women. Many presented with non-specific motor symptoms such as increased blinking (51.9%) or non-motor sensory features such as eye soreness or pain (38.7%), photophobia (35.5%), or dry eyes (10.7%). Non-motor psychiatric features were also common including anxiety disorders (34–40%) and depression (21–24%). Among cases presenting with blepharospasm in the Dystonia Coalition cohort, 61% experienced spread of dystonia to other regions, most commonly the oromandibular region and neck. Features associated with spread included severity of blepharospasm, family history of dystonia, depression, and anxiety. Conclusions: This study provides a comprehensive summary of motor and non-motor features of blepharospasm, along with novel insights into factors that may be responsible for its poor diagnostic recognition and natural history.

Abstract
This article reports the tolerance and long-term safety profiles of botulinum neurotoxin type A among Asian patients with benign essential blepharospasm (BEB) and hemifacial spasm (HFS). We performed a retrospective review of clinical documents and procedure records of consecutive BEB and HFS patients receiving onabotulinum toxin A (Botox) treatment in our clinic over the past 20 years. We reviewed the information of 105 patients diagnosed with BEB (n = 31) and HFS (n = 74). All of the patients were Asian. The mean age of disease onset was 59 (range 37-80) years old for BEB and 61 (range 31-83) for HFS. The mean follow up was 84 (range 12-240) months and the mean number of sessions per patient was 19 (range 1-61). The botulinum toxin dose per session increased significantly in both BEB (16.5 versus 21.6 units, p < .05) and HFS (22.6 versus 26.9 units, p < .05) patients after a mean of 18 sessions; however, the onset time, effective duration and subjective treatment outcome were similar over time in both BEB and HFS patients. At least one local complication was reported among 26% and 41% of patients with BEB and HFS respectively, with ptosis (32%) being most frequent.
