Toxic and Nutritional Optic Neuropathies
Diagnosis
Mainly clinical evaluation A history of undernutrition, bariatric surgery, or toxic or chemical exposure combined with typical bilateral cecocentral scotomata (caused by involvement of the optic disc and papillomacular fibers) on visual field testing justifies treatment. Laboratory testing for lead, methanol, suspected nutritional deficiencies, and other suspected toxins is done.
