Blepharospasm causes involuntary contractions of the muscles of the eyelids. The disorder can also lead to uncontrollable blinking and in some cases sufferers may be unable to open their eyes, which reduces their ability to carry out everyday activities. Learn more about the condition, its diagnosis and the different treatment options available.

The condition is normally diagnosed by a general practitioner based on the patient’s description and their symptoms. To date however, there is no test to confirm a diagnosis.

Blepharospasm has symptoms in common with other conditions and should not be confused with:

  • Ptosis: drooping of the eyelids caused by weakness or paralysis of a levator muscle of the upper eyelid;
  • Hemifacial spasm, an involuntary non-dystonic contraction of the muscles on one side of the face, caused by irritation of the facial nerve, which often causes exaggerated blinking.
