Xerophthalmia

Xerophthalmia refers to the group of eye signs and symptoms associated with severe Vitamin A deficiency. Vitamin A serves various essential functions in the eye and its deficiency can adversely affect the health of eyes. It is a major problem in developing countries and is a leading cause of preventable blindness worldwide. 

It can affect people of any age but children between the age of 2 to 6 years are more prone to this deficiency. The disease can be caused either due to improper consumption, metabolism, or storage of Vitamin A.

This disease can be easily prevented and treated by taking a proper dose of Vitamin A through diet and supplements. Immunization against certain diseases such as measles which serve as a precipitating factor for xerophthalmia can also help in preventing Vitamin A deficiency in children.
