Formatted Abstract/Summary
Fetal and neonatal vitamin A deficiency exhibits protean clinical manifestations, which reflect the importance of vitamin A in cell cycle fate, embryogenesis, and organogenesis. The metabolism and nuclear signaling roles of vitamin A derivatives are still to be fully elucidated. Key ophthalmologic manifestations of neonatal vitamin A deficiency include microcornea, Bitot spots, xerophthalmia, and anterior and posterior segment malformations. Historically, maternal hypovitaminosis A secondary to nutritional deficiencies has been prevalent in the developing world; however, maternal hypovitaminosis A and consequent neonatal malformation syndromes are being reported with increasing frequency following gastric bypass surgery for maternal morbid obesity. This chapter discusses vitamin A metabolism, clinical multisystem malformation syndromes associated with perturbations of vitamin A homeostasis and biosynthesis, and the role of vitamin A in ocular development.
