Abstract:
A 5-year-old boy with autism developed dry eye and xerophthalmia. Serum vitamin A was undetectable. Dietary history revealed a markedly altered intake consisting of only fried potatoes and rice balls for 2 years. Fried potatoes contain no vitamin A. Autism is a multifaceted developmental disorder infrequently accompanied by abnormal eating practices. To the authors' knowledge, most children with autism who develop dietary vitamin A deficiency have consumed an excess of fried potatoes. Attention to possible vitamin A deficiency is essential when fried potatoes are consumed exclusively.
