![]() It is common, does not affect vision and will likely go away on its own. Depending on which eye muscle is affected, you may have under eye twitching or a twitch in the upper eyelid.įatigue, too much caffeine or physical or emotional stress usually cause a general eye spasm. However, it’s possible for both eyes to experience a general spasm. General eye spasms are usually unilateral, meaning they only affect one eye at a time. This is a slight, temporary pulsing or flickering of the eyelid. When you think of an “eye twitch,” you’re probably picturing a general eyelid spasm. The types are organized by the severity of the twitch and whether other areas of the face are affected. There are three common types of eye twitching: general eyelid spasm, essential blepharospasm and hemifacial spasm. The medical term for eye twitching is myokymia. While an eye spasm may feel noticeable, it is usually subtle and not easily seen by others. When a problem occurs in one or more of these muscles, a twitchy eye may result. There are eye muscles that raise your eyelids, as well as muscles that lower them. Most eye twitching lasts only a few minutes, but it’s possible to experience eyelid twitching for weeks or longer. While it is generally successful, it is a major neurosurgical operation and serious complications are possible.An eye twitch (or more accurately an eyelid twitch) is an involuntary, uncontrollable eyelid spasm. ![]() A neurosurgical procedure for hemifacial spasm, microvascular decompression, also can relieve the facial spasms. Surgery to remove the involved muscles is occasionally needed in addition to botulinum toxin therapy.īotulinum toxin injections can relieve the eyelid and facial spasms in patients with hemifacial spasm. Side effects typically last 1 to 2 weeks while the good effects last 3 months. On rare occasions when side effects occur, they include drooping of the eyelids or double vision. The treatment is very successful with few side effects. The injection works for several months but will slowly wear off and usually needs to be repeated 3 to 4 times each year. Injection of botulinum toxin in very small quantities into the muscles around the eyes will stop the spasm. Botulinum toxin injections are now the most commonly recommended treatment for blepharospasm. ![]() Medications and biofeedback are rarely successful in managing blepharospasm. Some ophthalmologists recommend reducing caffeine usage.īlepharospasm can be treated with medications, biofeedback, injection of botulinum toxin, and surgery. Reducing stress, using warm soaks, correction of any refractive error, and lubrication of the eye with artificial tears may help. Minor eyelid twitches require no treatment as they usually resolve spontaneously. Rarely, hemifacial spasm is caused by a tumor pressing on the facial nerve, found with MRI testing. These conditions are distinguished by a careful clinical examination.
