Causes of Keromalacia

Corneal malacia may be caused by insufficient intake of vitamin A, vitamin A absorption disorders, excessive consumption of vitamin A, etc.

1, insufficient intake of vitamin A

from the diet too little vitamin A, can not meet their own needs, leading to corneal stromal cells due to lack of nutrition necrosis, keratomalacia.

2, vitamin A absorption disorders

with digestive tract diseases affect vitamin A absorption, resulting in too little absorption of vitamin A, unable to maintain the stability of corneal epithelial tissue metabolism, so corneal epithelial degeneration, resulting in keratomalacia.

3, vitamin A consumption The

body consumes a lot of vitamin A, resulting in insufficient vitamin A reserves in the body, will affect the normal function of the cornea, so that corneal epithelium stops growing, the development of keratomalacia.
