A 12-year-old boy from Massachusetts lost his vision due to limited fast pacing, which caused an irreversible degenerative process in the optic nerve. This became evident after his parents noticed changes in his appearance and admitted him to the hospital. According to specialists from the children's hospital in Boston, the boy was diagnosed with degenerative retinal disease associated with autism spectrum disorder. Earlier this year, he began experiencing vision problems in the morning and evening, which ultimately led to his complete blindness by the time he was admitted to the hospital. During his stay in the hospital, the boy received vitamins A, C, D, K, calcium, thiamine, copper, and zinc, as well as additional supplements in salads and cheese to diversify his diet, thanks to dietary therapy. After examination, doctors found that he lacked essential nutrients for the optic nerve. However, due to the seriousness of the case, there is a risk that vision restoration may not be possible. Researchers noted: "Unfortunately, degeneration of the optic nerve in the patient turned out to be extraordinarily severe."
