Traumatic optic neuropathy is one of the causes of visual loss caused by blunt or penetrating head trauma and is classified as both direct and indirect. Clinical history and examination findings usually allow for the diagnosis of traumatic optic neuropathy. There is still controversy surrounding the management of traumatic optic neuropathy; some physicians advocate observation alone, while others recommend steroid therapy, surgery, or both. In this entry, researchers tried to highlight traumatic optic neuropathy’s main pathophysiologic mechanisms with the most available updated treatment. Recent research suggests future therapies that may be helpful in traumatic optic neuropathy cases.

Traumatic optic neuropathy (TON) is a grave complication of closed head injury. It occurs in 0.7–2.5% of the population and is classified into direct and indirect TON [1].
Direct TON often results in complete vision loss and less chance of recovery than indirect TON. Direct TON usually occurs after bone fragments lacerate the optic nerve or when a concussion or contusion disrupts the optic nerve [2][3]. However, indirect TON usually develops due to blunt head or ocular trauma sustained via the oculofacial soft tissues and skeletal system to the optic nerve [4]. The visual loss may manifest several months after trauma; therefore, the diagnosis is always delayed [5]. TON management remains controversial; some physicians advocate observation alone, while others recommend high-dose corticosteroids, surgical optic canal decompression, or a combination. In this entry, researchers try to highlight the main updates involving the management of TON.
