What is it?
Myokymia is a general term used for a quivering or involuntarily movement of a single muscle or muscle group around the eye. While myokymia feels very conspicuous to a patient, it is barely perceptible to an observer. Myokymia starts rather suddenly and ends just as abruptly. The most commonly affected muscles are those that close the lids over the eye (orbicularis) and the superior oblique muscle, which moves the eye down and toward the nose. In the case of the latter, the patient sees double during an attack. With the orbicularis, a simple twitch is felt usually in the lower lid. These episodes may last a few seconds or minutes, rarely more than a few hours.
What Causes Eyelid Twitching?
The most frequently contributing factors are:
- lack of sleep
- excessive caffeine intake
What is the Treatment Usually?
Treatment at Solinsky EyeCare consists of correcting the basic cause of the disorder if it can be identified. Very rarely is this a manifestation of a more serious disease. In these cases there are other signs and symptoms to suggest more serious problems. No medical treatment is generally advised. In persistent, bothersome cases medicine can be given to quiet the muscle twitches. These drugs have the potential of causing side effects and generally should be avoided. Typically, more sleep and a warm compress is all that is needed to help alleviate the sporadic twitching – in addition to addressing the possible causative factors.
