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.

Radiología (English Edition)
The aim of this work is to provide a diagnostic approach to the potential causes of optic neuropathy, focusing on the radiological findings associated with this pathology. Various etiologies have been identified, including inflammatory and demyelinating optic neuritis, developmental and hereditary diseases, neurodegenerative disorders, infectious ...

Seminars in Ophthalmology, 1995
The hereditary optic neuropathies comprise a group of disorders in which the cause of optic nerve dysfunction appears to be inheritable, as demonstrated or suggested by familial expression or genetic analysis. Clinical variability, both within and among families with the same disease, often makes recognition and classification difficult.

The Neurologist, 2008
Anterior ischemic optic neuropathy (AION) is the most common cause of acute optic neuropathy after age 50, but may also occur in younger patients. The diagnosis is clinical and includes painless visual loss associated with a relative afferent pupillary defect and disc edema.

Continuum, 2019
This article reviews common infectious optic neuropathies, focusing on the more common and globally important entities.Novel infections continue to emerge and drift geographically over time; not infrequently, these have important neurologic or ocular features.

Neurologic Clinics, 1991
ION typically affects the older population with a sudden decrease in vision, altitudinal visual field loss, and a swollen optic nervehead. Systemic hypertension and diabetes mellitus are the most commonly associated medical problems. Occlusion of the posterior ciliary arterial blood supply to the retrolaminar optic nerve leads to axoplasmic stasis and ...

Mechanisms of optic neuropathy
Current Opinion in Ophthalmology, 1997Retinal ganglion cell death is the final common pathway of all human optic neuropathies. An understanding of how these cells die, either at the cell body or after axonal injury, may allow development of strategies for rescuing these cells and therefore ameliorating optic nerve disease.
