The information provided in this Resource Guide was developed by the National Eye Institute (NEI) to help patients and their families search for general information about blepharospasm. An eye care professional who has examined the patient's eyes and is familiar with his or her medical history is the best person to answer specific questions.
Benign essential blepharospasm, hemifacial spasm.
Blepharospasm is an abnormal, involuntary blinking or spasm of the eyelids.
Blepharospasm is associated with an abnormal function of the basal ganglion from an unknown cause. The basal ganglion is the part of the brain responsible for controlling the muscles. In rare cases, heredity may play a role in the development of blepharospasm.
Most people develop blepharospasm without any warning symptoms. It may begin with a gradual increase in blinking or eye irritation. Some people may also experience fatigue, emotional tension, or sensitivity to bright light. As the condition progresses, the symptoms become more frequent, and facial spasms may develop. Blepharospasm may decrease or cease while a person is sleeping or concentrating on a specific task.
To date, there is no successful cure for blepharospasm, although several treatment options can reduce its severity.
In the United States and Canada, the injection of Oculinum (botulinum toxin, or Botox) into the muscles of the eyelids is an approved treatment for blepharospasm. Botulinum toxin, produced by the bacterium Clostridium botulinum, paralyzes the muscles of the eyelids.
Medications taken by mouth for blepharospasm are available but usually produce unpredictable results. Any symptom relief is usually short term and tends to be helpful in only 15 percent of the cases.
Myectomy, a surgical procedure to remove some of the muscles and nerves of the eyelids, is also a possible treatment option. This surgery has improved symptoms in 75 to 85 percent of people with blepharospasm.
Alternative treatments may include biofeedback, acupuncture, hypnosis, chiropractic, and nutritional therapy. The benefits of these alternative therapies have not been proven.
Mexiletine for the Treatment of Focal Dystonia
The National Institute of Neurological Disorders and Stroke (NINDS) is currently recruiting patients to test the effectiveness of mexilitine, an oral medication, to treat Dystonia (involuntary muscle contractions). Patients will be evaluated by clinical rating scales and neurophysiological studies. In addition, researchers will test patient's reflexes in an attempt to find out where mexilitine works in the nervous system. For further information on this study, please visit the NINDS' website at http://www.ninds.nih.gov/disorders/blepharospasm/blepharospasm.htm or contact the NIH Patient Recruitment and Public Liaison Office at 1-800-411-1222.
The Doxil® Blepharospasm Treatment Trial
Doxorubicin injections in the eyelids are being studied as a way of relieving muscle spasms. Patients who participated in this study have experienced symptom relief since their last injection. No definite conclusions have been reached at this time. For additional information about this clinical trial, please visit the University of Minnesota Department of Ophthalmology website at http://www.med.umn.edu/ophthalmology/ or contact:
