Recently, the New England Medical Magazine (UK) has announced the case of a 12 -year -old boy not disclosing information in the country that lost his vision permanently.The boy started to have eye problems earlier this year, with an inferior vision in the morning and evening and only less in the daytime.

Soon, the situation became worse, he had to ask his parents to help and often bumped into the door and wall.One night, the boy woke up and screamed, saying that he could not see anything else.His parents immediately took him to the hospital, where the doctors discovered his diet made him seriously deficient in important nutrients to help maintain a healthy visual nerve.

Despite being supplemented and treated by feeding, experts still find the boy's vision loss is permanent.The hospital discovered that the boy had visual atrophy, the condition of optic nerve cells shrinking due to long -term damage.Doctors are concerned that "because the detection is too late, the treatment will not be effective".

The boy was impaired vision due to a nutritious diet, only eating regular sandwiches, chips, donuts and juice, resulting in serious shortage of vitamins A, C, D, copper and zinc.

Doctors at Boston Children's Hospital said the boy had a "avoiding disorder", that is, he would limit his food because he felt worried or did not like some colors, taste, endingcertain structure or taste.

The boy's parents described him as a "picky" person, completely opposing the test of new foods or vitamins because he did not like their taste.Two days before being taken to the hospital, the boy's parents found that there were swelling and scales around his eyes.Sometimes the boy stared at the wall instead of TV.

Before that,Bella, a girl with autism in England, also lack of vitamin A due to a limited diet (only jam, sandwich and chips), eventually leading to blindness.Vitamin A deficiency is also one of the most common causes of blindness in children in the United States.This nutrient is the main ingredient of Rhodopsin, a light -sensitive protein that helps the retina to produce pigments that allow people to see clearly in places with low light.

Vitamin D helps the eyes create tears, which is essential to prevent dry eyes and clean debris.Copper and zinc protects cells and structures in the retina, while vitamin C helps protect the eyes from UV rays.
