Keratomalacia is an eye disorder that leads to a dry cornea. One of its major causes is Vitamin A deficiency. When xerophthalmia (a major cause of blindness) persists for a long time, it results in keratomalacia. There is degradation of corneal epithelium billaterally which may also get vascularised. Later corneal opacities develop. Bacterial infection leads to corneal ulceration, perforation of cornea, and total blindness.
