ABSTRACT
To determine the prevalence of xerophthalmia at a traditional boarding school where children do not receive a diet adequate in vitamin A. A cross-sectional survey of 406 males residing in a Quranic traditional school was conducted using the World Health Organization xerophthalmia checklist. The association between the prevalence of night blindness and proportion of students staying at the school for 6 consecutive months and those eating solely at the school was investigated. The difference in age between children with night blindness and those without was investigated. Statistical significance was indicated by P<0.05. The prevalence of night blindness, conjunctival xerosis and Bitot's spots was 24%, 12.5% and 1%, respectively. None of the boys had corneal ulceration, corneal scars and corneal xerosis. No significant association was observed between the differences in mean age and development of night blindness [P=0.657]. There was a significant association between the duration of stay [cut-off of 6 months continuously] at the institute and the development of night blindness [P=0.023]. There was no statistical significance between regularly eating at the "maseed" and outside the "maseed" and the development of night blindness [P=0.75]. Children residing at a traditional school are vulnerable to developing xerophthalmia where the diet is inadequate in vitamin A. Institutional caregivers should be made aware of the importance of providing a balanced diet rich in vitamin A. Institutional caregivers should also be educated on the signs and symptoms of vitamin A deficiency for early detection of xerophthalmia
