Normal functions of the photoreceptors or light-sensory receptors of the eyes largely depend on the presence of vitamin A and its metabolites within the retina. Prolonged vitamin A deficiency leads to deterioration of these structures causing impaired vision. Adequate amounts of vitamin A are required for proper eye development in embryos and maintenance of normal anatomical structures of the eye, including the conjunctiva and cornea. As a whole, deficiency in vitamin A results to major destruction of eye structures and visual functions, impairing vision and ultimately leading to irreversible blindness. Blindness caused by vitamin A deficiency remains a public health problem, especially in developing countries resulting from vitamin-A-attributed corneal scarring. There is a significant difference between causes of prevalent cases of blindness across different levels of socioeconomic statuses. Studies also emphasize the overall impact of vitamin A deficiency to child morbidity, mortality and growth. Evidently, the concern for the emotional, social and economic costs also diffuses from the problem with blindness as a disability. Serious actions must be taken to help address the situation. Further studies are needed to evaluate measures most adept to combat vitamin A deficiency in a community with regards to cost and feasibility of the program, together with the strategies to detect subclinical VAD for early management; and hopefully, restore vision among the blind.
