Blepharospasm is a neurological condition characterized by forcible closure of the eyelids. Blepharo means "eyelid". Spasm means "uncontrolled muscle contraction". The term blepharospasm ['blef-a-ro-spaz-m] can be applied to any abnormal blinking or eyelid tic or twitch resulting from any cause, ranging from dry eyes to Tourette's syndrome to tardive dyskinesia.
What causes Blepharospasm?
The basal ganglion is the part of the brain responsible for controlling the muscles. Blepharospasm is associated with the abnormal functioning of the basal ganglion due to unknown reasons. In rare cases, heredity is known to play a role in the development of blepharospasm.
How is Blepharospasm diagnosed?
Blepharospasm can be diagnosed when symptoms are displayed during a comprehensive eye exam.
What are the treatment options?
BOTOX® injections to treat blepharospasm have proven effective in partially blocking the nerve impulses to the tiny muscles in the eyelid.
