"My eyes keep twitching - it looks as if I'm winking at people"
Uncontrollable twitching of the muscles round the eyes is called
blepharospasm or myokymia. Only the eyelid may be affected, or the
sufferer may keep blinking and closing the eyes repeatedly, or there may
be spasms of not being able to open the eyes for a few moments or for
longer periods. Sometimes the muscles of the lower face and the jaw are
involved as well, so that trying to open the eyes causes these muscles
to contract into a grimace. The twitching may be worse when the
individual is tired or under stress, and it is often aggravated by
bright or flickering light (such as that from a TV) or irritants such as
smoke or wind.
Blepharospasm is not a dangerous condition, because it does not spread
to other muscles of the body, but it can be embarrassing not to have
control over one's facial expression. It is probably caused by a fault
in the part of the brain that controls movements (the basal ganglia).
Although stress makes it worse, relaxation techniques do not seem to
help. In fact, there is no cure, but it can be improved by tiny
injections of botulinum toxin into the affected muscles. For this
treatment, your GP would have to refer you to a neurology department
specializing in movement disorders. The treatment has to be repeated
several times a year.
