What is eyelid twitch?
Eyelid twitch or twitching is a series of rapid, uncontrolled contractions or spasms of one or all four eyelids. The twitches often occur in irregular rhythms. The medical term for this symptom is myokymia. Sometimes the term eye twitching is used to describe blepharospasm, a condition characterized by increased involuntary eye blinking. Blepharospasm is classified as a dystopia, a disorder in which the nervous system signals muscles to contract inappropriately. Blepharospam typically involves all four eyelids.
Eyelid twitch may occur with other eye symptoms, such as watery eyes and irritated or red eyes or eyelids. Sometimes eyelid twitch appears along with facial tics, which are other involuntary movements of the face including grimacing and nose twitching.
The vast majority of spontaneous eye twitch episodes are benign, self-limited, and leave no clues as to their cause. The most common known causes of eye twitch include fatigue, stress, anxiety, and excessive caffeine intake. Eyelid twitch may appear in response to irritation caused by smoke, dust, or a foreign body in the eye. Allergies and infections may also cause irritation that leads to twitching. Eyelid twitch is seen in primary congenital glaucoma. Various conditions that affect the central nervous system and brain, such as stroke, can also result in eyelid twitch.
In most cases, eyelid twitch goes away on its own with rest or removal of irritating factors. If you have persistent eyelid twitch, contact your health care provider to determine the underlying cause and to obtain any treatment that may be needed.
Eyelid twitch is not an emergency unless it is associated with a stroke. Seek immediate medical care (call 911) if you, or someone you are with, have symptoms of stroke such as sudden numbness or weakness of the face or a limb, especially on one side of the body, sudden confusion, difficulty seeing, sudden vision changes, sudden difficulty with coordination, or sudden severe, unexplained headache.
Eyelid twitch usually goes away on its own. Seek prompt medical care if it does not resolve within a week, if eyelid twitch closes your eye completely or involves other parts of your face, if you have facial paralysis or partial facial paralysis, if your upper eyelid droops, or if you experience discharge, redness, and swelling in or around the eye.
