Blepharospasm is a rare neurologic disorder in which the person experiences uncontrolled abnormal blinking or eyelid movement (i.e. twitching). It is mainly seen in mid-age or old age women, however, it is also reported in children as a result of another eye disease. It usually starts with one side but affects both sides after some time. It may become progressively harder for affected individuals to keep their eyes open.

Types: There are two types of Blepharospasm:

1. Eyelid twitching
2. Benign Essential Blepharospasm

Eyelid twitching usually goes away on its own. But people with Benign Essential Blepharospasm can develop severe and chronic (long-term) eyelid twitching. The commonest type is Benign Essential Blepharospasm in which the eyelids blink frequently and involuntarily.

The reason behind Blepharospasm is not known, however, stresses, drugs, Vitamin B12 deficiency, and some other diseases could be involved.

Treatment: If eyelids keep twitching for more than a few weeks the person needs to go to the eye doctor.  Firstly, the underlying reason should be identified and treated. If it still exists, Vitamin therapy, Botox injection, or consultation with Neurosurgeon are the other essential treatment options.
