Delivery Of Oral Doses Of Vitamin A To Prevent Vitamin A Deficiency And Nutritional Blindness

Approximately 8 to 10 million new cases of xerophthalmia due to vitamin A deficiency occur each year, with as many as % to 1 million children developing potentially blinding corneal disease. While vitamin A deficiency is the leading cause of blindness among children in developing countries, even milder states of deficiency carry an increased risk of morbidity and mortality, making its prevention a major public health priority. Three basic preventive strategies exist: (1) dietary modification through a variety of horticultural and nutrition education techniques to increase the routine availability and consumption of food sources of vitamin A, (2) fortification of a centrally processed, locally available and consumed food.
