Types of Spasms
Benign Essential Blepharospasm (BEB) is caused by an uncontrolled nerve signal in the brain that stimulates the eyelid muscles. Constant involuntary blinking and squeezing of the eyelids causes visual interruptions in the patient’s day to day activities. Hemifacial spasm (HFS) is commonly caused by an irritation of facial nerve on one side, leading to involuntary spasms on one half of the face. Meige syndrome involves spasms over the entire face. Myokimia is a more localized form of spasm, that typically involves a single eyelid or periocular area. Botunlinum toxin injection (BOTOX) into the eyelid muscles can significantly reduce the muscle spasm that causes contraction or twitching of the eyelids.
