Eye problems such as macular degeneration are common in aged people. Blurred vision or vision loss can occur due to serious problems like macular degeneration or neurological disorders. Other than serious conditions like macular degeneration, various problems can affect the eyes. Eye twitching is a common problem and is characterized by uncontrollable blinking. A serious form of eye twitching is also termed as blepharospasm. Its symptoms may be associated with those of neuromuscular disorder. Eye twitching may be among the signs of a neurological disease like Parkinson’s disease. Eye twitching affects the basal ganglion that is responsible for controlling brain muscles.
Causes
Eye twitching can happen to anybody. Causes of eye twitching are not clear. Eye twitching may happen at any time with no warning signs. Sometimes, signs of eye twitching may disappear while the person starts concentrating on a different task. Some other signs of eye diseases may occur along with or before eye twitching viz. pink eyes, blepharitis, light sensitivity, and dry eyes. Heredity factors may be responsible for causing eye twitching in rare cases. Benign essential blepharospasm is a serious form of twitching, which is a neurological disorder.

Can This Be Among Signs of a Disease?
Signs of a neurological disease may include eye twitching. Though eye twitching is not a serious problem or a disease, it may be among the signs of another disease. It can last for short time or it may last for weeks or longer. Usually the signs involve twitching of the lower eyelid, but the upper eyelid can also twitch in some cases. A serious form of twitching of the eye is caused by neurological disease. It may be among the signs of chronic neurological diseases like Tourette’s syndrome.
Doctors can detect and treat the signs of such neurological diseases. Usually, the signs that occur temporarily are harmless. It may be difficult to treat a twitching eye in rare cases. The twitches can be treated with Botox injections that are effective in stopping muscle contractions. If twitching affects the whole eye, visit the doctor. This can help rule out whether twitching is associated with dry eyes or any other neurological disease. Full examination by an eye specialist is required to determine whether twitching is harmless or among signs of any neurological disease.
