However, it is unclear what range of oxygen saturation is appropriate to minimize retinopathy without increasing adverse outcomes. METHODS We performed a randomized trial with a 2-by-2 fac...

Erythropoietin (Epo) is a true hematopoietic hormone produced in response to lowered oxygen tension. The liver is the main source of Epo during most of fetallife, but the liver to kidney switch occurs around birth so that 90% of Epo synthesis takes place in the kidney very soon in life. E!evated serum Epo levels are observed at birth in the case of maternaI hypertension, akoholism, or diabetes ...
PURPOSE To measure vitreous, aqueous, subretinal fluid and plasma levels of vascular endothelial growth factor in late stages of retinopathy of prematurity. METHODS Interventional study. We enrolled patients with clinical diagnoses of bilateral stage V retinopathy of prematurity, confirmed by b-scan ultrasound and programmed for vitrectomy. During surgery we took samples from blood, aqueous, ...
