What causes eyelid twitching?

Eyelid twitching is a common phenomenon. Some people simply think that it is caused by lack of rest, but they don’t know that it may also be caused by a certain disease, such as facial muscle spasm, reflex blepharospasm, etc., and must be treated actively.

Clinical causes of eyelid twitching:

Benign muscle fiber twitching: occurs in conditions such as fatigue and emotional stress. It is a unilateral, temporary twitching of the muscles around the eye. This condition generally does not require treatment and can be recovered by resting and relaxing.

Facial muscle spasm: In addition to unilateral eyelid twitching, there is also paroxysmal irregular twitching of the facial muscles on the same side, which is mostly caused by vascular compression of the facial nerve. For this clear vascular and nerve compression, microvascular decompression is an effective treatment method.

Reflex blepharospasm: It is caused by local eye lesions such as keratitis, iritis and other diseases. This situation will improve after treating the local eye lesions.

Idiopathic blepharospasm : characterized by intermittent or persistent involuntary closure of the double eyelids, without any eye disease.

Meige syndrome: In addition to bilateral eyelid twitching, there is also twitching of the lower facial muscles and even the neck muscles. In this case, local injection is more effective and can also effectively relieve facial spasm.

Hysterical blepharospasm: Symptoms are similar to those of essential blepharospasm, but suggest that treatment is effective.

Whether it is eyelid twitching or facial spasm, in addition to space-occupying lesions, it is mostly due to factors such as mental tension, eye muscle fatigue, lack of sleep, precursors of chronic diseases and sequelae of facial paralysis, which weaken the conduction of nerve function, cause insufficient nutrition of the eyes, and form contact-type adhesions between capillaries and nerve endings, which pull the muscles and cause involuntary twitching. The contact area between capillaries and nerve endings increases, and the contact adhesion becomes linear adhesion, and the throbbing becomes twitching, forming facial spasm, and the lesions are also in the eyes. From a diagnostic point of view, there is a clear difference between simple eyelid twitching and hemifacial spasm. In simple eyelid twitching, the facial muscles generally do not have sunken, asymmetrical nasolabial grooves, or linear atrophy bands on the cheeks; when blinking, there is no feeling of pulling in the orbicularis oris muscle.

Through the above introduction, we now know that eyelid twitching does not mean anything. If the situation is more serious, it can only represent the occurrence of a disease, which requires us to pay enough attention to it. If the situation is serious or the eyelids have been twitching, we must go to the hospital's ophthalmology department for professional examination in time.
