Poor Diet Can Lead to Blindness, Case Study Shows
An extreme case of “fussy” or “picky” eating caused a young patient’s blindness, according to a new case report published today in Annals of Internal Medicine.
Nutritional optic neuropathy is a dysfunction of the optic nerve which is important for vision. The condition is reversible, if caught early. But, left untreated, it can lead to permanent structural damage to the optic nerve and blindness.
The researchers concluded that the patient’s ‘junk food’ diet and limited intake of nutritional vitamins and minerals resulted in the onset of nutritional optic neuropathy. They suggest the condition could become more prevalent in future, given the widespread consumption of ‘junk food’ at the expense of more nutritious options, and the rising popularity of veganism if the vegan diet is not supplemented appropriately to prevent vitamin B12 deficiency.
