THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -Vitamin A is essential for good vision. It is a component of the protein rhodopsin, which allows the eye to see in low-light conditions. According to the American Academy of Ophthalmology, a deficiency in vitamin A can lead to night blindness.

Detailed explanation-2: -Vitamin A plays an important role in your vision. To see the full spectrum of light, your eye needs to produce certain pigments for your retina to work properly. Vitamin A deficiency stops the production of these pigments, leading to night blindness.

Detailed explanation-3: -What are the consequences and implications? Night blindness is one of the first signs of vitamin A deficiency. In its more severe forms, vitamin A deficiency contributes to blindness by making the cornea very dry, thus damaging the retina and cornea.

Detailed explanation-4: -Just 2 doses of vitamin A given annually to all children 6-59 months of age prevents their developing vitamin A deficiency blindness. Because vitamin A deficiency can have a range of consequences, including an increased risk of child mortality, the term now used is “vitamin A deficiency disorders” (VADD).
