The duration of blepharospasm is about one month and will improve naturally if adequate rest is maintained. Blepharospasm occurs in middle-aged and older patients and is caused by abnormal discharges in the branches of the facial nerve, causing uncontrolled, regular twitching of the orbicularis oculi. The constant squeezing of the eyes can be a nuisance to normal life and affects appearance. To speed up recovery, Chinese acupuncture, eye heat packs, and neurotropic, supportive treatments such as methylcobalamin and intravenous ganglioside infusions can be used. Blepharospasm does not cause serious harm and can gradually heal itself within a month. For individual patients with more stubborn conditions, there are ways to cure them by injecting botulinum toxin into the eyelid area to eliminate the spasm.
