BLEPHAROSPASM is an involuntary contraction, or twitching, of one of the muscles that controls the eyelids, causing them to close and thus obstruct vision.
Why does this happen?
Blepharospasm can occur spontaneously for no specific reason. It can also be a natural reaction to stress, tiredness or lengthy exposure to bright light. If the condition progresses, eyelid spasms become stronger and occur more frequently, sometimes causing the eyelid to remain closed for lengthy periods of time. Performing everyday tasks can then become difficult as vision becomes more obstructed.
What is the treatment?
Injections of Botulinum toxin (Botox) around the affected area can relieve, and sometimes eliminate, the symptoms.
