keratomalacia

Softening or ‘melting’ of the cornea usually in severely malnourished children whose body stocks of vitamin A have become exhausted. Corneal melt leads to internal infection and irremediable blindness and this is the fate of millions of children every year in economically depressed parts of the world. A small regular dose of vitamin A, as from a few fleshy green leaves, will prevent this.

keratomalacia

Vitamin A deficiency in which the cornea becomes desiccated at first and then softens, at which stage it is associated with infiltration, pannus, necrosis, opacification and the eye becomes blind. There is also a lack of reaction to inflammation leading to a destruction of the eye if infection occurs. It is part of a general systemic condition due to malnutrition. Associated with this condition are night blindness, faulty growth of bone, xerophthalmia, etc. See hemeralopia.

At present, there is a concern about vitamin A deficiency (xerophthalmia, keratomalacia etc.) and its contribution in the high rate of IMR by increasing the severity-and the risk of the three main health threats facing children in low social-economic communities in some countries; diarrhoeal diseases, measles and pneumonia.
Malnutrition among the young is also a severe problem giving rise to problems like anaemia, goiter, keratomalacia, rickets, scurvy osteo malacia, etc.
