Abstract

Like metabolic disorders, certain nutritional deficiency leads to corneal (and eye) lesions. Protein deficiency is an important one and the corneal damage is seen in advanced stage. Unquestionably vitamin A deficiency gives rise to devastating eye problems. This is discussed in detail and includes details of vitamin A and its metabolism in the retina. Vitamin B complex does not give rise to eye problem so commonly; but it does occur and may resemble that of certain other deficiency states. Vitamin C also causes minor changes. Lack of vitamin E, uncommon though, leads to mainly retinal problems.
