Traumatic optic neuropathy (TON) is defined as damage to the optic nerve resulting in loss of visual function that cannot be explained by other ocular pathology. Mechanisms of TON can be classified into “direct” or “indirect”. Investigation of TON via various imaging modalities has been reported. The management and appropriate timing of intervention of indirect TON has been much debated. To date, there is insufficient evidence and guidance in determining the most appropriate treatment. In this review, we summarize the clinical features and investigations, and propose a guideline for the management of TON.
