Purpose: Dysthyroid optic neuropathy (DON) is a serious complication of Graves orbitopathy that can result in irreversible and profound visual loss. Controversy exists regarding the pathogenesis and management of the disease. The authors provide an overview of the current understanding of DON and present a therapeutic guideline.

Current Neurology and Neuroscience Reports, 2006
The subjects of this review are the various types of optic nerve disease that involve autoimmune mechanisms, broadly defined. These include optic neuropathy caused by direct inflammatory involvement of the nerve parenchyma and optic nerve damage as an ischemic sequel to primary vasculitis, although there is naturally some overlap between the two ...

International Ophthalmology, 1981
The clinical course and ophthalmic manifestations of an eight year old child with acute undifferentiated leukemia and unilateral blindness secondary to leukemic optic nerve head infiltration are described. At autopsy the involved nerve head and peripapillary retina demonstrated massive leukemic cell infiltration and hemorrhagic necrosis.

Archives of Ophthalmology, 1988
Vision loss progressing over several days, reduced pupil reactions to light, and swollen optic nerves were the clinical features in six patients with severe renal disease manifested by uremia, anemia, and (in four patients) moderately or severely elevated blood pressure. In two patients pale edema of the optic nerve head extended into the macula.

Neurology, 1982
Three patients presented with unilateral progressive optic neuropathy. None of these patients had signs of symptoms referable to the chiasm or eye, thus confining their decline in vision to the optic nerve. Clinical and neuroradiographic evidence suggested a meningioma involving the optic nerve at the orbital-canalicular junction in one patient and the

Knowledge concerning the pathophysiologic mechanisms of traumatic optic neuropathy is limited. The optic nerve is a tract of the brain. Therefore, the cellular and biochemical pathophysiology of brain and spinal cord trauma and ischemia provide insight into mechanisms that may operate in traumatic optic neuropathy.

Toxic optic neuropathy is a complex, multifactorial disease potentially affecting individuals of all ages, races, places, and economic strata. Etiology includes nutritional, environmental, toxicologic, and genetic factors. Most cases of nutritional amblyopia are encountered in disadvantaged countries.

Current Opinion in Ophthalmology, 2013
Many causes of toxic optic neuropathy have been described to date and novel causes of toxicity are continuously being added to the current literature. The pathophysiological basis for the toxicity or a direct causal relationship is yet to be determined for many of these agents.
