Exotropia is the outward deviation of an eye. It is the misalignment of the eyes in which one or both of the eyes turn outward. It is the opposite of crossed eyes, or esotropia. Exotropia may occur from time to time (intermittent exotropia) or may be constant, and is found in every age group. The symptoms include:
• Decreased vision
• Decreased depth perception
• Outward deviation of the eyes, often intermittently at first
• Sensitivity (closing one eye) in bright light
HOW IS EXOTROPIA DIAGNOSED?
An ophthalmologist diagnoses cases of Exotropia and a close examination of the eye including an ocular motility evaluation allows the doctor to accurately treat cases of Exotropia. While surgery is recommended to treat Exotropia, in many cases, doctors recommend vision therapy to correct Exotropia which includes visual exercises.
HOW IS EXOTROPIA TREATED?
Treatment of Exotropia depends on the type of misalignment. Intermittent Exotropia may reduce with age, but it may not disappear fully. Use of special glasses may correct the misalignment. Patching therapy is followed in some cases. In cases where the symptoms are severe and the person experiences eye strain, surgical correction may be required.
DID YOU KNOW?
The various risk factors involved in exotropia are:
• Positive family history of strabismus (misaligned eyes), amblyopia, childhood cataract, or glaucoma
• Some genetic disorders that affect the eyes
• Pediatric cataracts or glaucoma
• But most often there are no known risk factors in children with exotropia
