Strabismus is a condition where the two eyes do not aim in the same direction. One eye may be turned either in–commonly known as crossed eyes or out–commonly known as wall-eyed.
Strabismus has different causes. The condition is usually caused by poor eye teaming skills which include confusion in the signals traveling between the eyes and the brain. The “eye-brain connection” is not working properly. Developmental difficulties in a child may cause problems with eye “teaming,” which is the ability to point the eyes in the same direction.
When the two eyes work together, a person will have better overall visual skills. The younger the child, the easier it is to learn correct visioual habits. Like walking or talking, these skills can be taught and developed at any age. Early detection and treatment is important.
If the eyes points in different directions, each eye sends a different picture to the brain. This can sometimes, but not always, produce obvious confusion visial signals.
The brain, however, will eentually ignore or suppress messages from one eye in order to make sense of what is seen. A person may not be aware this is happening because suppression causes no pain. To the brain, it is as if one eye is closed. But the normal process of fusion (merging the two pictures from each eye into one) is disrupted. A number of functional visual difficulties can occur as a result of strabismus, but the only obvious symptom is eye turn.
