Eyelid twitch: MedlinePlus Medical Encyclopedia

P An eyelid twitch is a general term for spasms of the eyelid muscles. These spasms happen without your control. The eyelid may repeatedly close (or nearly close) and reopen. This article discusses eyelid twitches in general.

T Causes
P The most common things that make the muscle in your eyelid twitch are fatigue, stress, and caffeine. Once spasms begin, they may continue off and on for a few days. Then, they disappear. Most people have this type of eyelid twitch once in a while and find it very annoying. In most cases, you won't even notice when the twitch has stopped.
P You may have more severe contractions, where the eyelid completely closes. These can be caused by irritation of the:
- Surface of the eye (cornea)
- Membranes lining the eyelids (conjunctiva)
P Sometimes, the reason your eyelid is twitching cannot be found. This form of eyelid twitching, called blepharospasm. It lasts much longer and is often very uncomfortable. It can also cause your eyelids to close completely.

T Symptoms
P Common symptoms of twitching of eyelid are:
- Repeated uncontrollable twitching or spasms of your eyelid (most often the upper lid)
- Light sensitivity (sometimes, this is the cause of the twitching)
- Blurry vision (sometimes)

T Treatment
P Eyelid twitching most often goes away without treatment. In the meantime, the following steps may help:
- Get more sleep.
- Drink less caffeine.
- Lubricate your eyes with eye drops.
P If twitching is severe or lasts a long time, small injections of botulinum toxin can control the spasms.

T Outlook (Prognosis)
P The outlook depends on the specific type or cause of eyelid twitch. In most cases, the twitches stop within a week.

T Possible Complications
P Unrecognized cornea injury can cause permanent eye injury. This occurs rarely.
