An 11-year-old boy presented with loss of vision in the left eye following a motor vehicle crash. Clinical examination showed a complete loss of visual acuity (no light perception) and a relative afferent pupillary defect of the left eye that was suggestive of an optic nerve injury. An emergency orbital magnetic resonance imaging scan showed a hyperintense left optic nerve (Figure, A) on T2-weighted imaging. Complementary high-resolution proton density–weighted magnetic resonance images revealed a complete transection of the left optic nerve (Figure, B) localized in the apical part of its intraorbital segment.
