In some cases, especially in developing countries, vitamin A supplements may be necessary – particularly for infants, young children, and people who are pregnant or breastfeeding.
While vitamin A deficiency is uncommon in places like the U.S., its impact globally is severe. The World Health Organization reports it as the leading cause of preventable blindness in children around the world.
This case echoes a similar incident reported by the Daily Mail in October last year, where a 12-year-old boy from Massachusetts also lost his sight due to a nutrient-poor diet.
