Because of the role thiamine plays in maintaining healthy nerves, a deficiency can affect the optic nerve in your eyes.
Specifically, this can cause swelling of the optic nerve that leads to blurred vision. Left untreated, optic nerve damage can eventually result in vision loss.
Still, this is quite rare.
Some small studies have found that supplementation used to correct thiamine deficiency may also significantly improve vision in these instances.
In an animal study, researchers found that a thiamine compound was effective for preventing alcohol-induced optical nerve damage.
However, the human studies are “case reports,” meaning they followed a single individual. Plus, the results of animal studies don’t always hold true when applied to human health. That means we can’t apply this research to the general population, and we need more studies.
