Blepharospasm is caused by abnormal brain function in the part of your brain that controls muscles. Symptoms can be triggered by something as minor as stress and being overly tired. Or it could be triggered by a neurological condition. Such conditions would include Touretteâs syndrome or Parkinsonâs disease.
Symptoms are involuntary blinking and closing of the eyes; in severe cases, people cannot open their eyes. Spasms may be made worse by fatigue, bright light, and anxiety. Treatment of blepharospasm involves injecting botulinum toxin type A into the eyelid muscles; treatment must be repeated in most instances. Anxiolytics may help. Surgery to cut the periorbital muscles is also effective but, because of potential complications, is considered only if botulinum toxin is ineffective.
