What is Benign Essential Blepharospasm?

Benign essential blepharospasm (BEB) is a progressive neurological disorder characterized by involuntary muscle contractions and spasms of the eyelid muscles. It is a form of dystonia, a movement disorder in which muscle contractions cause sustained eyelid closure, twitching or repetitive movements. BEB begins gradually with increased frequency of eye blinking often associated with eye irritation. Other symptoms may include involuntary winking or squinting of one or both eyes, increasing difficulty in keeping the eyes open, and light sensitivity. Generally, the spasms occur during the day, disappear in sleep, and reappear after waking. As the condition progresses, the spasms may intensify, forcing the eyelids to remain closed for long periods of time, and thereby causing substantial visual disturbance or functional blindness. It is important to note that the blindness is caused solely by the uncontrollable closing of the eyelids and not by a dysfunction of the eyes. BEB occurs in both men and women, although it is especially common in middle-aged and elderly women.

Is there any treatment?

In most cases of BEB the treatment of choice is botulinum toxin injections (there are several formulations; the most commonly used is Botox), which relax the muscles and stop the spasms. Other treatment options include medications (drug therapy) or surgery.

What is the prognosis?

With botulinum toxin treatment most individuals with BEB have substantial relief of symptoms. Although some may experience side effects such as drooping eyelids, blurred or double vision, and eye dryness, these side effects are usually only temporary.

What research is being done?

The NINDS supports a broad program of research on disorders of the nervous system, including BEB. Much of this research is aimed at increasing understanding of these disorders and finding ways to prevent, treat, and cure them.
