Abstrakt: Purpose: Although less frequent than consecutive exotropia, consecutive esotropia is a well-known type of strabismus when it follows the surgical correction of an exotropia. Spontaneous conversion from initial constant, large-angle exotropia beyond the age of 3 months to esotropia or orthophoria, however, is not common. We describe a series of infants who presented a spontaneous evolution from a large-angle infantile exotropia to either an orthophoria or a spontaneously consecutive esotropia.
Methods: Cases of infants examined in the pediatric neuro-ophthalmology clinic of a tertiary ophthalmology department between 2009 and 2015, and having presented an early large-angle exotropia that spontaneously converted into an esotropia or orthophoria-i.e., without any previous surgery or botulinum toxin injection-were studied.
Results: Ten cases (6 M:4 F) were followed up. Median age at first exotropia assessment was 3.88 months (SD = 6.35). Median age at spontaneous conversion to esotropia or orthophoria was 7.23 months (SD = 14.73). Six patients suffered from severe neurologic or metabolic diseases, three had neonatal respiratory distress syndrome, and one was healthy.
Conclusion: Spontaneous conversion from initial large-angle exotropia to esotropia or orthophoria can be encountered. The cerebral maturation of visual structures probably accounts for this uncommon strabismus sequence.
