Two hundred and thirteen Sudanese children (4-60 months old) with malnutrition were examined for signs of xerophthalmia. Sixty-three (29%) of these children were found to have varying stages of xerophthalmia. These included 35 (56%) patients with conjunctival xerosis, 12 (19%) with Bitot's spots, seven (11%) with corneal xerosis, seven (11%) with corneal ulceration and two (3%) with corneal scar. Direct questioning of the parents of these children revealed evidence of night blindness in nine (4%) of all patients. All nine patients had signs of xerophthalmia which showed good response to vitamin A therapy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
