The clear facts about eye disorder.

STRABISMUS is a disorder in which the two eyes do not line up in the same direction and, therefore, do not look at the same object at the same time. The condition is more commonly known as "crossed eyes".

When this occurs, two different images are sent to the brain - one from each eye. This confuses the brain, and it may learn to ignore the image from the weaker eye. If the strabismus is not treated, the eye that the brain ignores will never see well. This loss of vision is called amblyopia or "lazy eye".

Someone with strabismus may have depth perception loss (no 3D vision). It can affect someone's ability to play sports, drive or even pursue a career where perfect vision is required.

Up to 5% of all children in the UK have some type or degree of strabismus.

In most children with strabismus, the cause is unknown. In more than half of these cases, the problem is present at or shortly after birth.

The first step in treating it is to prescribe glasses. Amblyopia must be treated first. A patch is placed over the better eye, forcing the weaker eye to work harder. If the eyes still do not move correctly, eye muscle surgery may be needed. Different muscles in the eye will be made stronger or weaker. However, if eye muscle repair surgery straightens the eyes and can make the squint disappear, it does not necessarily fix the poor vision of a lazy eye.

Orthoptic treatment or eye "reeducation" can also help improve strabismus.
