A retinopatia da prematuridade é um transtorno vasoproliferativo que afeta bebês extremamente prematuros, potencialmente levando a uma deficiência visual grave ou cegueira. A exposição de recém-nascidos prematuros à hiperóxia regula para baixo o fator de crescimento endotelial vascular da retina. Os vasos sanguíneos se contraem e podem se tornar obliterados, resultando em atrasos no desenvolvimento vascular retiniano normal. Baixo peso ao nascer, idade gestacional jovem e gravidade da doença (p.ex., síndrome do desconforto respiratório, displasia broncopulmonar, sepse) são fatores associados. Ocorre primariamente em bebês com peso extremamente baixo ao nascer por causa da cessação da maturação vascular retiniana normal. | |||

Retinopathy of prematurity is a vasoproliferative disorder that affects extremely premature infants potentially leading to severe visual impairment or blindness. Exposure of newborn premature infants to hyperoxia down regulates retinal vascular endothelial growth factor. Blood vessels constrict and can become obliterated, resulting in delays of normal retinal vascular development. Low birth weight, young gestational age, and severity of illness (e.g. respiratory distress syndrome, bronchopulmonary dysplasia, sepsis) are associated factors. It primarily occurs in extremely low birth weight infants because of the cessation of normal retinal vascular maturation. | |||
