Crossed eye or Congenital Esotropia
Most infants are born with eyes that are not aligned at birth. It is common for infants to appear as if they have esotropia, or inward turn of the eyes because the bridge of the nose is not fully developed. This false appearance of an inward turning is known as epicanthus. As the infant grows, and the bridge narrows the eyes will appear more normal. Infantile esotropia usually appears between the ages of 2 and 4 months.
Lazy eye or Amblyopia develops when the brain shuts off or suppresses vision in one eye. About 3 to 6 percent of children under the age of 6 develop amblyopia. Treatment is most successful before age 5 or 6, but if ignored, amblyopia can result in permanent vision loss.
Identifying the problem is not easy because children can get along fine using only one eye. The less-used eye may look perfectly normal, even though the child is not using it to see. The mother can carry out a simple test by focussing the light of a torch on a wall and observing how the child follows the light.
