Eyelid twitching comes across a commonplace disorder and in medical terms, it is known myokymia. It is an involuntary contraction of eyelid muscles and is more likely to affect the lower eyelid. The treatment for eyelid twitching is subject to its severity.
A few of the most common causes associated with twitching of eyelids include stress, allergies, fatigue or dry eyes, and it may also come to fore as a result of using caffeine. Similarly, poor nutrition or vision problems may also come across as a cause of twitching of eyes.
In most cases, an eyelid twitch is minor and recurs over time after staying for a period of 2-3 days in a single instant. However if the twitching of eyes is more severe, it may last for longer periods of time. The eyes may entirely open up and close by themselves, and the process repeats itself. It may become annoying and may interfere with everyday life as well.
In some cases, if the twitching is severe, it may last for weeks at a time. This type of twitching may occur as a side effect of Blepharospasm, which at times shows up for no apparent reason. Blepharospasm may be caused as resulting from issues related to flow of blood to the facial nerve, or a neurological injury.
The treatment selection of eye twitching is determined by whether the twitch is mild or severe. It involves limiting caffeine and taking more rest, applying warm compresses and using topical eye drops or over-the-counter oral antihistamines. Botox injections may be used to treat severe eye itch, and work by paralysing eye muscles.
