Blepharospasm is a tonic spasm of the orbicularis oculi muscle which leads to intermittent or complete closure of the eyelids.1 Benign essential blepharospasm (BEB) is bilateral dystonia of orbicularis oculi muscles characterized by spasmodic involuntary eyelid closure in the absence of any other ocular or adnexal cause.23 It is not uncommon to see secondary blepharospasm which is due to an ocular or adnexal disease along with essential blepharospasm in the same patient.4BEB is more common in women (2-3 times) as compared to men and more so in people over 50 years of age.13 Post menopausal women with thyroid dysfunction and those using phenothiazines are more prone to BEB.4
