A blepharospasm, blepharo meaning eyelid and spasm meaning uncontrolled muscle contraction, is any abnormal, involuntary contraction or twitch of the eyelid. It normally refers to benign essential blepharospasm (BEB) which is a focal dystonia — a neurological movement disorder involving involuntary and sustained contractions of the muscles around the eyes. Symptoms sometimes last for a few days then disappear without treatment, but in most cases the twitching is chronic and persistent, causing lifelong challenges.
Common Symptoms: excessive blinking or spasms of the eyes, uncontrollable twitches of the eye muscles and dryness of the eyes.
Options for care: Doctors often recommend botulinum toxin injections (such as Botox) to induce localized, partial paralysis to prevent twitching and muscle spasms. Botulinum toxin effectiveness diminishes over time, but supplementation with Zytaze has been proven to enhance the results and extend the duration of effect.
