Dystonia Clinical Trial
Official title:
Diagnostic and Rating Tools for Blepharospasm
The aim of this study is to develop new rating scales to help diagnose and measure the severity of blepharospasm. This is a condition involving a lot of blinking and spasms of eye closure that people can't control. This study will also test some video software to see if it can help diagnose people or tell the severity of disease using only a video recording of an exam. There is an additional plan to create an educational video to teach others the proper use of the scale and video software.
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.
