Blepharospasm is an involuntary twitching or contraction of the eyelids. Most people you ask will tell you that at some time or another they have experienced the eye twitch. It can last for a few seconds or go on for months. So what is it and why does it happen?
Blepharospasm is characterised by abnormal, involuntary blinking or spasm of the eyelids. Blepharospasm may begin with a gradual increase in blinking or eye irritation and as the condition progresses these symptoms become more frequent.
There are several treatment options available to reduce the severity of blepharospasm including oral medications and botulinum toxin (BOTOX). Botulinum toxin is injected into the muscles of the eyelids and temporarily paralyzes these muscles relaxing the spasm.
