title: Erythropoietin and retinopathy of prematurity.
abstract: Erythropoietin (EPO) is a glycoprotein that regulates many functions of an organism: It stimulates the production of red blood cells and it has angiogenic and neuroprotective properties in newborn infants. Retinopathy of prematurity (ROP) is a frequent cause of visual impairment in preterm newborn infants and it has two distinct phases in which hypoxia-induced angiogenic factors are involved. The relationship between EPO and ROP is derived from the observation of studies done on the haematopoietic effect of EPO. The first observations suggested that a precocious treatment with EPO increases the risk of ROP, while the most recent reports suggested that the late treatment with high doses of rhEPO can increase the risk of ROP. All these studies were not designed to demonstrate the relationship between EPO and ROP. Further studies specifically designed should be performed. New ongoing studies on the neuroprotective role of EPO should consider this objective. In the mean time the use of EPO in the neonatal period should be cautious, mainly in very low birth weight infants.
