Question

The deficiency of which of the following vitamin causes keratomalacia?

• A. Vitamin K
• B. Vitamin D
• C. Vitamin A
• D. Vitamin E

Answer 1

The correct option is C Vitamin A

Keratomalacia is an eye disorder that results from Vitamin A deficiency. Vitamin A is required to maintain specialized epithelia (such as in the cornea and conjunctiva). A lack of vitamin A leads to atrophic changes in the normal mucosal surface, with loss of goblet cells, and replacement of the normal epithelium by an inappropriate keratinized stratified squamous epithelium.
