Involuntary Eyelid Blinking

Blepharospasm (pronounced "bla-for-o-spaz-m") is the name for a condition in which the eye blinks excessively and involuntarily. It usually occurs in persons in their 50's or 60's, and to women more commonly than men.

While its cause is not yet known, it is believed that blepharospasm is caused when there is a miscommunication among the signals between the brain and the eye muscle. The patient may also experience spasms of the face and neck muscles as well. Some people may have an episode of blepharospasm while for others, it becomes a chronic condition.

Blepharospasm is also known as dystonia (impaired or disordered muscle tone) or dyskinesia (a defect in voluntary movement).

It is important to have blepharospasm evaluated by a trained eye health professional because it may be a symptom and not a condition unto itself. Sometimes, blepharospasm may be the result of dry eye, eye infection, corneal disease, acute glaucoma or several other types of ocular conditions.

Stress, fatigue, bright lights, and situations where one may need to stare ahead (watching television or driving) may exacerbate blepharospasm. However, a variety of relaxation techniques may decrease symptoms temporarily.

Treatment for blepharospasm include medications, local injection of botulinum toxin (also known as "botox" injections which are used for cosmetic purposes) and surgery. As with treatment for any kind of condition, it is important to discuss with your physician the treatment that works best for you.
