Conjunctival Xerosis
b The keratinized epithelial cells die and create characteristic Bitot's spots in the palpebral fissure.

Epidemiology: Due to the high general standard of nutrition, this disorder is very rare in the developed world. However, it is one of the most frequent causes of blindness in developing countries.

Etiology: Vitamin A deficiency results in keratinization of the superficial epithelial cells of the eye. Degeneration of the goblet cells causes the surface of the conjunctiva to lose it luster (Fig.4.5a). The keratinized epithelial cells die and are swept into the palpebral fissure by blinking, where they accumulate and create characteristic white Bitot's spots (Fig. 4.5b). Xerosis bacteria frequently proliferate.

Treatment and prognosis: The changes disappear after local and systemic vitamin A substitution. Without vitamin A substitution, the disorder will lead to blindness within a few years.

Diabetes is a disease that affects the way your body uses food. Normally, your body converts sugars, starches and other foods into a form of sugar called glucose. Your body uses glucose for fuel. The cells receive the glucose through the bloodstream. They then use insulin a hormone made by the pancreas to absorb the glucose, convert it into energy, and either use it or store it for later use.
