Toxic and Nutritional Optic Neuropathies
Key Points
Toxic or nutritional optic neuropathy is reduced visual acuity caused most often by drugs or toxins or nutritional deficiencies, particularly in people with alcohol use disorder or in those who have undergone bariatric surgery. Vision loss is usually gradual and partial, involving central vision. Diagnosis is mainly clinical (eg, bilateral cecocentral scotomata, suggestive history). Treat the cause (eg, stopping exposure to a drug or toxin, improving nutrition).
