Abstract

Traumatic optic neuropathy (TON) refers to optic nerve injury resulting from direct and indirect head and facial trauma. The pathogenesis of indirect TON has not been fully elucidated, and the management of TON remains controversial. In this review article, I review the recent literature regarding TON and discuss how to manage indirect TON.

  FIGURE 1 Representative case of forty-nine male who was diagnosed with left superior, lateral and inferior orbital wall fracture due to fall-down. (A) Color vision and visual field test result at 1 month after trauma. Note the impairment of color vision and total visual field constriction of left eye of the patient, (B) optical coherence tomography and visual evoked potential (VEP) test result at 18 months after trauma. Note the 360° retinal nerve fiber layer thinning around the left disc and decreased response of left eye in VEP test. OD: right eye, OS: left eye, VECP: visually evoked cortical potential, ISCEV: the International Society for Clinical Electrophysiology of Vision.
