Blepharospasm Tools

Blepharospasm is a chronic disorder characterized by too many contractions in the muscles around the eye and nearby facial muscles, leading to involuntary eye closure. This study involves a comprehensive evaluation for patients with blepharospasm, other eye and face disorders, and people without any neurologic or eye or face disorders. It addresses abnormal movements of the muscles around the eye, pain in those muscles, psychological accompaniments, and impact on regular daily life. The evaluation for each participant will be done on a single visit, and it may take up to 1.5 hours to complete. Each participant in this study will be asked to do the following: * Provide a copy of medical records and provide a medical history relating to the diagnosis of blepharospasm. * Have an examination by a neurologist or ophthalmologist to reveal the features and extent of dystonia or other eye and face disorders. The examination will be video recorded so it can be reviewed later by different experts. * Complete some questionnaires about quality of life and psychiatric well being The doctors will also complete various scales and questionnaires based on the participant's study visit.
