Although modern medical science has long confirmed that the common saying “left eye jumping money, right eye jumping disaster” has no scientific basis, but there are still many people (especially in rural areas) because of the eyelid jumping to see a doctor. This shows that the phenomenon of eyelid jumping is widespread, and people are not clear about the causes of eyelid jumping. Why do eyelids jump? In medicine, the eyelids are called eyelids. There are two muscles in the eyelid, one is called the orbicularis oculi, which is shaped like a wheel and surrounds the eye, and when it contracts the eyelid closes; the other muscle is called the levator aponeurosis, and when it contracts the eye opens. These two muscles are constantly contracting and relaxing so that the eyes can open and close. If the nerves that govern these two muscles are stimulated by some factor, the two muscles become excited at the same time, and there will be repeated contractions, or even spasms or tremors, and the eyelids will involuntarily flutter. When the eyelid jumping occurs, most people feel obvious themselves, but the next person can not see, only individuals can be seen by the next person eyelid jumping. The actual fact is that you will be able to get a lot of people to do this. Many people experience physiological eyelid jumping, the attack is transient, the attack is very short, often just a few seconds, the degree of jumping is also not serious. This type of eyelid flutter generally does not require special treatment. As long as the eyes are closed and rested for a while, a local massage or hot compress will make the eyelid jumping disappear. Pathological eyelid jumping needs treatment Some people not only have eyelid jumping, but even the corners of their mouth and half of their face twitching together, and feel nauseous and dizzy. This kind of eyelid jumping can only be made to stop when the cause is found and eliminated. The causes include exertion, stress and disease. The more severe pathological eyelid jumping is caused after a facial muscle spasm. This kind of eyelid jump is a sign of intracranial disease, mainly because the facial nerve, which governs the muscle movement of the eyelid, is compressed by blood vessels, resulting in abnormal nerve impulses, and is difficult to heal on its own. Therefore, if you experience prolonged and gradually increasing eyelid jumping, you should go to the hospital promptly. If it is determined that the facial muscle spasm is caused by the compression of the facial nerve root by blood vessels, it should be controlled by oral carbamazepine tablets medication. For unsatisfactory or ineffective results of medication for facial muscle spasm, microvascular decompression surgery is recommended.
