Lower And Upper Eyelid Twitching Causes
The upper eyelid twitching occurs due to the involuntary spasms of the eyelid muscles and it can also occur in the lower eyelid, being called lower eyelid twitching. The involuntary spasm of the muscles both in the upper and lower eyelid can cause the repeatedly closing of the eyelid and its re-opening. However, lower eyelid twitching is not so common but it can still happen. Any patient should know that eye twitching is harmless in almost all cases.
The cause of eyelid twitching is still a mystery for the doctors but they have identified few factors that can trigger the condition and these are fatigue, stress and caffeine. Sometimes the spasms may start and continue off and on for several days and then they simply disappear. This type of twitching eyelids is experienced by most people and because they are mild many individuals are not able to say when the twitching stopped.
However, the spasms can become more powerful and can result in the closing or nearly closing of the eye. This severe type of twitching eyelids is normally a sign of other medical conditions related to the eye, such as irritation of the cornea or of the conjunctiva (the membranes lining the eyelids). Patients experiencing this type of twitching of the eyelid complain of it as being very uncomfortable because it also tends to last much longer.
Patients who have involuntary muscle spasms of the eyelids usually experience other symptoms such as sensitivity to light or blurry vision.
Since the cause of the eyelid twitching is basically unknown, there is no effective treatment for this condition. Patients are normally recommended to get more sleep and to avoid or drink less caffeine and in some cases eye drops can be prescribed for lubricating the eye. In cases of severe twitching the doctor may prescribe small injections of botulinum but these cure the spasm only temporarily. Warm compresses and gentle massaging the twitching eye as well as over-counter eye drops of antihistamines can help in slowing the contractions in mild cases. Also, individuals are recommended to spend less time in front of the computer because it can diminish the frequency of the eyelid twitching.
The twitching generally stops within a week but this can vary depending on what causes it and what type of twitching we are talking about. Though complications from eyelid twitching are possible, they are very rare and could consist in the permanent eye injury.
Whereas in most of the cases eyelid twitching is not a serious condition that would require medical attention, when the symptoms worsen the opinion of an eye doctor should be sought. An ophthalmologist should be consulted if the eyelid twitching is still existent after 1 week or if it causes the complete closing of the eye or it involves other parts of the face. Persons who also experience redness, swelling or discharge from the eye should see a specialist.
The upper eyelid twitching is a common condition of the eyelid which most of the time does not require special care but in some cases it can be a sign of more serious underlying medical conditions.
