Nictitating spasm

Nictitating spasm is uncontrollable contraction of muscle surrounding the eye. Outwardly it looks as a strong closing of blepharons. The nictitating spasm is followed by an edema of blepharons, lacrimation. There is a vicious circle: the spasm generates consequences causing intensification of spasm.

At first person feels a rapid blinking which can’t be controlled (clonic blepharospasm). Usually at first only one eye is affected. In time spasm extends on both eyes.

In young people the nictitating spasm can arise without obvious causes and quickly disappears. The hysterical bilateral nictitating spasm appears suddenly at hysteria (usually at young women) and disappears in some hours. At this kind of nictitating spasm “pressing points” in places of an trigeminal nerve branches outlet are revealed. The nictitating spasm stops when pressing on them.

Frequently in 2-3 years a nictitating spasm becomes persistent. It is shown as closing eyes tight (tonic blepharospasm) that leads to problems in everyday life.

The nictitating spasm leads to stresses and depressions. In many cases in time the spasm extends on all facial muscles.

Often the nictitating spasm stops at activity of mouth muscles (smoking, sucking of candies, nibbling sunflower seeds). Alcohol and, emotional activation can take spasm off. Sometimes closing of one or both eyes helps. Practically it is always possible to find position of eyes in which the nictitating spasm stops. Usually this is extreme abduction to sideways. The nictitating spasm decreases in a sitting position and lying.

The strong provoker of nictitating spasm is a sunlight therefore wearing of dark glasses and work performance at the semi closed blepharons is recommended to the patient.
