Photo 1. Xerophthalmia. Vitamin A deficiency is a common cause of blindness among pre-school children in the tropics, especially in Asia. The dryness of the cornea and conjunctiva give the eye a dull, hazy appearance.

Bitot's spots.

Photo 2. Bitot's spots. These are silver-grey foamy spots, usually external to the cornea and often bilateral. They are thought to be due to avitaminosis A.


Photo 3. Keratomalacia. A softening or coagulative necrosis of the cornea occurs in chronic, severe vitamin A deficiency. As for kwashiorkor, vitamin A deficiency may be precipitated by acute infections in undernourished children.
