Esotropia in Children
The most common type of strabismus is esotropia, which occurs when either one or both eyes turn in toward the nose. Some children are born with this condition. Alternatively, it can start at about age two and a half. When esotropia occurs in these older children, eyeglasses can often help to treat the condition by correcting the child's vision for farsightedness or hyperopia. This can reduce or eliminate the crossing by changing the child's need for excessive focusing.
