http://www.eyemdlink.com/Condition.asp?ConditionID=421 Strabismus Also referred to as: Crossed Eyes Strabismus is a general term referring to ocular misalignment due to extraocular muscle imbalance. In short, the eyes are "crooked". Strabismus occurs in approximately 2% of children under 3 years of age and about 3% of children and young adults. The condition affects males and females equally. Strabismus has an inherited pattern, i.e., it is much more likely if one or both parents are affected. However, many cases occur without any family history of the disorder. Strabismus is important to recognize, primarily because, in childhood, it is often associated with the development of amblyopia, or lazy eye. Amblyopia refers to reduced vision, uncorrectable with glasses or contact lenses, due to failure or incomplete development of the visual cortex of the brain. Strabismus is not only important from the standpoint of amblyopia, however. It is also important for other functional and cosmetic reasons. Strabismus is associated with reduction of depth perception and, if onset is in adulthood, double vision. Furthermore, strabismus presents a cosmetic concern, especially for school-age children. My son had the same condition as well as his father and several males in the father's side of the family. In our son's case they told us,even if he had the surgery there is good chances the eye muscle will reverse and pull the opposite way and he would have to have many more surgery's though life. So we choose instead eye excises and today its a lot better even though he still wear glasses, it doesn't turn in near as much. His father on the other hand, the eye goes where it wishes.
