INTRODUCTION Ocular manifestations of vitamin A deficiency, particularly night blindness, have been recognised since antiquity. Animal research and clinical observations early in the twentieth century indicated that vitamin A was important for numerous bodily functions. Humans deficient in vitamin A grew poorly, suffered more persistent or severe infections, and subsequently developed characteristic ocular manifestations termed “Xerophthalmia or Dry eye.[1] ”Vitamin A deficiency precipitated by Protein Energy Malnutrition & other disease www.wjpr.net Vol 8, Issue 1, 2019. 1685 Janani et al. World Journal of Pharmaceutical Research such as diarrhoea, measles, malaria in children which either causes increased utilization or mal-absorption of vitamin A and ultimately blindness. Xerophthalmia The term Xerophthalmia is reserved (by a joint WHO and USAID Committee, 1976) to cover all the ocular manifestations of vitamin A deficiency, including not only the structural changes affecting the conjunctiva, cornea and occasionally retina, but also the biophysical disorders of retinal rods and cones function.[2] The rhodopsin system in the rod cells of retina is much more sensitive to deficiency than is the iodopsin system in the cone cells. As a result, rod function is impaired early on, resulting when sufficiently marked in impairment of night vision.[3] Impairment of cone function (i.e., day vision and color vision) is rarely seen clinically. In 1982, WHO introduced new Xerophthalmia classification is as follows. XN- Night blindness; X1A- Conjunctival Xerosis; X1B- Bitot’s spot; X2- Corneal Xerosis; X3A- Corneal Ulceration/ Keratomalacia ( < 1/3 corneal surface) ; X3B- Corneal Ulceration/ Keratomalacia ( > 1/3 corneal surface ); XS- Corneal scar due to Xerophthalmia; XF- Xerophthalmic fundus.[4] Source and Metabolism of vitamin A[5] Vitamin A or retinol, is a fat-soluble substance found in liver and in egg yolk and dairy products. Carotenoids a potential provitamin A precursor that can be converted to retinol are present in green leafy vegetables, yellow fruits. 1 IU of Vitamin A is equivalent to 0.3µg of retinol, 0.55µg of retinyl palmitate, 0.6µg of β-carotene, 1.2µg of other provitamin carotenoids. Some 50-90% of ingested retinol is absorbed in the small intestine and transported to the liver where it is stored as retinyl palmitate. When needed, it is released to blood stream as retinol then utilised by target cells, such as retinal photoreceptors, epithelial lining throughout the body. When vitamin A intake is ≤ 180- 450µg/ day of retinol, liver storage is drained to maintain serum retinol at a normal level (well above 0.7µmol/litre or 200µg/litre). www.wjpr.net Vol 8, Issue 1, 2019. 1686 Janani et al.

World Journal of Pharmaceutical Research responsible for nimesha and unmesha of eyelids.[11] If intake of vitamin A, Zinc, iron rich foods is low for prolonged periods, serum retinol level drop, cellular function is impaired results Xerophthalmia and deficiency like anemia, impaired resistance to infection and this leads to PEM. It can be correlated with Apatarpanajanya vyadhi mentioned by Caraka. Caraka mentioned deha, agni, varna, bala, oja kshaya.[12] It should be treated with sadhyosantarpana[13] which means excess intake of vitamin A, Zinc, iron rich food. Aacharya Shusruta mentioned netra rogas that can be correlated with signs and symptoms of Xerophthalmia are as follows.
