Doctor blames poor diet on 17-year-old U.K. boy going blind

An extreme case of“fussy eating” caused blindness in a teenager from the United Kingdom, according to a new report published Monday in the Annals of Internal Medicine.

When Denize Atan, the study’s lead author, met the 17-year-old boy at Bristol Eye Hospital, his eyesight had been deteriorating for two years. But what shocked her most was “how long the patient’s eating behavior had persisted,” Atan said Tuesday. “By the time I first met him, he had followed the same diet for (approximately seven) years.”

The teen, who has not been named, told doctors that since elementary school, “he had a daily portion of fries from the local fish and chip shop and snacked on Pringles (Kellogg), white bread, processed ham slices, and sausage, ”the study said.

The risks of poor nutrition are often associated with obesity, poor cardiovascular health and cancer, but Atan’s study warns that it can also have disastrous, and sometimes irreversible, effects on the nervous system, including vision.

The boy was first treated three years earlier by his family physician for “tiredness .” According to the report, the then-14 year old was a picky eater but was“otherwise well and took no medications .” Early testing showed he had low levels of vitamin B12 and macrocytic anemia, which were treated with B12 shots and “dietary advice.”

By 15, the boy’s hearing began failing, and then the vision complications arrived. Doctors could not determine what was causing either symptom.

After two years of progressive vision loss, the boy was declared legally blind.
