Lack of vitamin A is the leading cause of childhood:
- xerophthalmia
- blindness
Xerophthalmia refers to a condition caused by vitamin A deficiency that results in dryness of the eyes and can lead to blindness. Blindness is also a significant outcome of severe vitamin A deficiency, especially in children.
Deafness and Wernicke-Korsakoff's syndrome are not primarily associated with vitamin A deficiency. Wernicke-Korsakoff's syndrome is related to thiamine (vitamin B1) deficiency, typically associated with chronic alcoholism.
