Bitot's Spots consist of fragments of keratinized epithelium. They can be triangular in shape and vary in appearance from "cheesy greyish" to silver-grey and can appear shiny.
A common cause of Bitot's Spots is deficiency of Vitamin A. This condition is more common in developing countries where child nutrition is often poorer than in developed nations. If left undiagnosed and untreated, Bitot's spots may be lead to night blindness, perhaps eventually to xerophthalmia, and in worst cases, blindness.
Bitot's Spots are an example of a medical condition directly associated with malnutrition.
