RT Journal Article SR Electronic T1 Impact of retinopathy of prematurity on ocular structures and visual functions JF Archives of Disease in Childhood - Fetal and Neonatal Edition JO Arch Dis Child Fetal Neonatal Ed FD BMJ Publishing Group Ltd and Royal College of Paediatrics and Child Health SP F179 OP F184 DO 10.1136/archdischild-2014-306207 VO 100 IS 2 A1 Alistair Fielder A1 Hannah Blencowe A1 Anna O'Connor A1 Clare Gilbert YR 2015 UL http://fn.bmj.com/content/100/2/F179.abstract AB The preterm baby may develop ophthalmic sequelae which can be due to prematurity per se, due to retinopathy of prematurity (ROP) or due to neurological damage. Focusing on the former two, we discuss how in high-income countries the risk of sight-threatening ROP is largely confined to babies <1000 g birth weight (BW), whereas in low-income or middle-income countries babies exceeding 2500 g BW can be blinded. The effects of prematurity and ROP are presented as regional and global estimates of acute-phase ROP and the consequent mild/moderate and severe visual impairment. We discuss sequelae and how they affect the eye and its shape, strabismus and finally consider their impact on visual functions, including visual acuity, the visual field, colour vision and contrast sensitivity.
