Cross-eyed, that is, congenital esotropia, usually occurs after birth or within a few days after birth. Congenital esotropia is rarely seen in clinic because the parents of children rarely see a doctor in the neonatal period, but strabismus is more common in the early postpartum period, because parents of children often can't make accurate and objective judgments on the eye position of their babies under one year old, and may mistake the instability of binocular visual axis for congenital esotropia. In addition, in infancy, because the nose is not well developed, there are many epicanthus and false strabismus, which are also easy to cause confusion. At this time, some acquired accommodative strabismus may also occur, which will cause confusion in diagnosis.
It has no effect on children.
