Differential Diagnoses
Exotropia, Acquired
Oculomotor Nerve Palsy
Other Problems to Be Considered
Exotropia of the newborn (This is seen in as many as 70% of newborns. Unlike congenital exotropia, it completely resolves by the sixth month of life.)
Consecutive exotropia (from previous esotropia surgery)
Duane retraction syndrome type II
Workup
Imaging Studies
- Radiographic imaging if neurologic signs are present
- Radiographic imaging if craniofacial anomalies are present
Other Tests
- Chromosomal studies if any other facial or systemic anomalies are present
