Crossed Eyes (Strabismus)

What Is It?

Crossed eyes, also called strabismus, occurs when the eyes appear to be misaligned and point in different directions. Strabismus can occur at any age, but is most common in infants and young children. It can be seen in up to 5 percent of children, affecting boys and girls equally.  

Strabismus can occur part of the time (intermittent) or all of the time (constant). Intermittent strabismus may worsen when the eye muscles are tired — late in the day, for example, or during an illness. Parents may notice their infant's eyes wandering from time to time during the first few months of life, especially when the infant is tired. This occurs because the infant is still learning to focus his or her eyes and to move them together. Most babies outgrow this intermittent strabismus by the age of 3 months.
