According to doctors at Wills Eye Hospital, Philadelphia, the most common divergent strabismus in childhood has a variable onset, often between six months and four years. The disorder occurs in 1.2% of children by seven years of age and occurs equally...
in males and females.
Duane syndrome commonly affects girls more often than boys, and the left eye more often than the right eye.
Congenital nystagmus is thought to be present at birth, but is usually not apparent until the child is a few months old. Acquired nystagmus occurs later than six months of age, and can be caused by stroke, such diseases as multiple sclerosis, or even a heavy blow to the head. It is not known how many people suffer from nystagmus, but it is thought to be one in 1,000 adults, and one in 640 children in the United States, according to the Nystagmus Network.

Definition
Eye muscle surgery is surgery to weaken, strengthen, or reposition any of the muscles that move the eyeball (the extraocular muscles).
Purpose
The purpose of eye muscle surgery is generally to align the pair of eyes so that they gaze in the same direction and move together as a team, either to improve appearance or to aid in the development of binocular vision in a young child. To achieve binocular vision, the goal is to align the eyes so that the location of the image on the retina of one eye corresponds to the location of the image on the retina of the other eye.
In addition, sometimes eye muscle surgery can help people with other eye disorders (nystagmus and Duane syndrome, for example).
Other Information
Surgeons aim for results of 20/20 or better so that you can perform most daily activities without your glasses. However, there is a possibility that after surgery, you may need to wear reading glasses or corrective lenses for at least some activities.
