Imaging Studies

Radiographic imaging is indicated if neurologic signs and/or craniofacial anomalies are present.

High-resolution MR imaging enables direct imaging of the ocular motor nerves. In a cohort of 247 consecutive patients with strabismus, Kim et al demonstrated ocular motor nerve abnormalities by high resolution MRI in 98/112 (88%) of patients with congenital or developmental neuropathic strabismus.

Other Tests

Chromosomal studies may be performed if any other facial or systemic anomalies are present.
