Esotropia and exotropia are types of strabismus, which is a condition in which the eyes are not properly aligned. Esotropia means that one eye is deviated inward and is often called crossed eyes. Exotropia is when one or both eyes look outward, often called wall-eyed.
Although newborns' eyes may wander or cross sometimes, the eyes usually straighten by 2 to 3 months of age. If the condition continues and is left untreated, it can lead to:
Causes of esotropia and exotropia are mostly unknown. Children with a family history of the disorder are more likely to get them. They are also common in children who have other systemic (chromosomal or neurologic) disorders.

Esotropia and exotropia can be intermittent or constant. The most noticeable symptom is one or either eye wandering inward or outward.
