Abstract

This study determined the prevalence of ocular manifestation of vitamin A deficiency in Orang Ash (Aborigine) children. Night blindness was found in 16.0% of the children, conjunctiva xerosis in 57.3%. Bitot's spot in 2.8%, corneal xerosis in 0.5% and corneal scars in 5.6%. These findings show that history of night blindness had sensitivity, specificity and predictive value (positive) of 47.2, 98.1 and 96.2%, respectively, compared with the standard diagnosis procedure using luxometer readings.
