Benign Essential Blepharospasm (BEB)



Type of disease: Rare conditions

Benign essential blepharospasm 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. Benign essential blepharospasm occurs in both men and women, although it is especially common in middle-aged and elderly women. Most cases are treated with botulinum toxin injections. The exact cause of benign essential blepharospasm is unknown.
