The eyes should work together as a team.
Strabismus occurs most often in young children.
There are many causes for this breakdown in binocular vision. Most commonly, strabismus is inherited. In other patients, a deviation will result from a high degree of farsightedness. Strabismus also may occur after a loss of vision in one eye due to a disease process. When there is a loss of vision in one eye, children under the age of four years will usually develop esotropia, whereas the older patient generally develops exotropia.
