Blurred Vision
Just as the peripheral nerves rely on thiamine, so does the optic nerve. Thiamine deficiency can cause the optic nerve to swell, and severe cases can cause optic neuropathy, resulting in blurred vision or even blindness.
Many people with a thiamine deficiency find that their vision improves when the deficiency is resolved through supplementation.4BL;, Gratton SM;Lam. ‘Visual Loss and Optic Nerve Head Swelling in Thiamine Deficiency without Prolonged Dietary Deficiency.’ Clinical Ophthalmology (Auckland, N.Z.), U.S. National Library of Medicine, pubmed.ncbi.nlm.nih.gov/24899800 The longer the deficiency goes undetected, the greater the risk of long-lasting or permanent damage to the optic nerve.
