Exotropia - Neonatal Disorders

What is Exotropia?

Exotropia is a type of strabismus where one or both eyes turn outward. It is the opposite of esotropia, where the eyes turn inward. Exotropia can be constant or intermittent and is often noticeable when a child is tired or focusing on distant objects.

How Common is Exotropia in Children?

Exotropia is relatively common in children. It is one of the most frequent forms of strabismus in the pediatric population. The prevalence can vary depending on the population studied, but it is generally seen in about 1% to 2% of children.

What Causes Exotropia?

Exotropia can be caused by a variety of factors including genetic predisposition, neurological disorders, and issues with the muscles that control eye movement. Sometimes, no specific cause can be identified. It may also be associated with conditions such as Down Syndrome or cerebral palsy.

How is Exotropia Diagnosed?

Diagnosis typically involves a comprehensive eye examination by a pediatric ophthalmologist. Tests may include visual acuity tests, examination of the eye alignment, and an assessment of the movement of the eyes. Sometimes, additional tests like refraction or imaging studies may be necessary to rule out underlying conditions.

What are the Symptoms of Exotropia?

Common symptoms include outward turning of the eye, especially when the child is daydreaming, tired, or looking at distant objects. Other symptoms can include double vision, squinting or closing one eye in bright sunlight, and problems with depth perception.

What Are the Treatment Options?

Treatment for exotropia may include glasses, eye patching to strengthen the weaker eye, vision therapy, and in some cases, surgery. The choice of treatment depends on the severity and frequency of the exotropia, as well as the underlying cause.

Can Exotropia be Prevented?

There is no sure way to prevent exotropia, but early detection and treatment can help manage the condition effectively. Regular pediatric eye exams are crucial for early identification and management.

What is the Prognosis for Children with Exotropia?

The prognosis for children with exotropia varies. With early intervention and appropriate treatment, many children can achieve good ocular alignment and function. However, if left untreated, exotropia can lead to amblyopia (lazy eye) and other vision problems.

When Should Parents Seek Medical Advice?

Parents should seek medical advice if they notice any signs of exotropia in their child, such as one or both eyes turning outward, squinting, frequent closing of one eye, or complaints of double vision. Early consultation with a pediatric ophthalmologist can lead to better outcomes.
