Benign essential blepharospasm (BEB) is a focal dystonia that causes involuntary occlusion of the eyelids as result of bilateral contraction of orbicularis oculi muscle. A 51-year-old female patient evaluated at the outpatient clinic with complaints of contraction and closure of the left eye for about 11 years and the same complaints of right eye for 10 years. Cranial magnetic resonance imaging was normal and blepharospasm was diagnosed based on the clinical and neurological evaluation. The patient underwent a botulinum toxin-A injection and was called for control 2 weeks later. BEB is a disease that seriously affects the quality of life of the patient, sometimes it can cause functional blindness. The time between diagnosis and treatment may be delayed in atypical cases. For this reason; differential diagnoses of atypical cases should be done well.
