Eye Conditions and Treatment
Blepharospasm is treated in the Oculoplastic & Reconstructive Surgery Service
Also called a tic, is the persistent or repetitive involuntary contraction of the orbicularis oculi muscle (the circular muscle around the eye), which produces uncontrolled blinking and squeezing of the eyelids. It is usually bilateral (involving both eyes) and may be accompanied by uncontrollable orofacial and head and neck movements; the spasms disappear during sleep. It usually occurs in older persons. It may be due to irritative lesions on the cornea or conjunctiva. Emotional stress and fatigue make it worse. People with blepharospasm have normal eyes. Visual disturbance is due solely to the forced closure of the eyelids. In severe cases, patients with blepharospasm can be functionally blind because they cannot open their eyes.
