Toxic amblyopia
Medical condition
From Wikipedia, the free encyclopedia
Toxic amblyopia, or nutritional optic neuropathy, is a condition where a toxic reaction in the optic nerve results in visual loss. Various poisonous substances may cause the condition as well as nutritional factors.[1]
Tobacco amblyopia is a form of toxic amblyopia caused by tobacco containing cyanide. Tobacco amblyopia is marked by a gradual impairment of vision characterised by visual field defects and hindered central vision.[citation needed]
Methyl alcohol amblyopia occurs through acute poisoning by methyl alcohol and may lead to complete blindness.[citation needed]
Since the term toxic amblyopia is a misnomer according to modern definition of amblyopia, it is now more accurately termed as toxic retinopathies or neuropathies.[2]
