Polymorphisms of Vascular Endothelial Growth Factor and Retinopathy of Prematurity.

Purpose: Retinopathy of prematurity (ROP) is a major problem among preterm survivors of neonatal intensive care. Neovascularization of the retina is prominent in the proliferative stages of ROP and is under the control of factors such as vascular endothelial growth factor (VEGF). The authors investigated the association of ROP with VEGF genetic polymorphisms and clinical (maternal, perinatal, neonatal) risk factors among preterm infants admitted to the neonatal intensive care unit.

Comparison of digital imaging screening and indirect ophthalmoscopy for retinopathy of prematurity.

The aims of this study were to determine the incidence and severity of retinopathy of prematurity (ROP) using digital imaging screening, confirm findings by indirect opthalmoscopy, and document risk factors of ROP in the neonatal intensive care unit (NICU) of a large tertiary hospital in a developing country. This prospective cohort study included infants with gestational age (GA) ≤ 32 wk, birth weight (BW) ≤ 1,500 g, or older and heavier neonates who were critically ill. Two hundred twenty two eyes (111 infants) were screened with digital imaging (Ret-Cam) and indirect ophthalmoscopy until retinal vascularization was complete or the disease regressed.
