Brief Summary:
Retinopathy of prematurity (ROP) is a common retinal neovascular disorder and major cause of vision impairment or blindness, despite current treatment of late stage ROP. Because the visual disorders after treatment are often poor, preventive therapy for ROP is still lacking. Although ROP is a multifactorial disease, the altered regulation of vascular endothelial growth factor (VEGF) and insulin-like growth factor (IGF-1) have been implicated in the pathogenesis of ROP. Vitamin A is one of the most important micronutrients affecting the health of children. Supplementing newborn infants with vitamin A within the first 2 days of life reduced infant mortality by almost 25%, with the greatest benefit to those of low birth weight. Vitamin A has been used in this population prophylactically for chronic lung disease with the large doses and no reported significant adverse effect exists. It is suggested that vitamin A-retinoids and their active metabolite, retinoic acid (RA) have highly potent antiangiogenic activity by inhibiting VEGF expression. Vitamin A (retinol) is converted into retinoic acid in cells. However, the significance of Vitamin A administration has not been investigated to our knowledge in an experimental ROP infant. The aim of this study was to perform prospective, multicenter, randomized design to demonstrate the preventive effect of Vitamin A on ROP.
