Eye lid twitching is seen because of spasms of the orbicularis oculi muscle
of the eyelids which is supplied by facial nerve
The commonest cause is called essential blepharospasm
where no underlying cause can be found out.
The treatment for the condition is by injection of Botulinium toxin. It is the most commonly performed treatment. I advice you to consult your eye doctor or oculoplastic surgeon for the treatment of the condition.
