title: [Epidemiological,and physiopathological findings in retinopathy of prematurity: the authors' personal cases].
abstract: The authors present a retrospective epidemiological study on retinopathy of prematurity (ROP), performed on 738 newborns with a gestational age of 34 +/- 2.41 weeks and birth weight of 1971 +/- 351 g. They excluded all cases with severe respiratory distress and other pathological conditions. First stage of ROP shows no correlation with gestational age and birth weight, whereas second and third stages of ROP show an inverse correlation with the above mentioned factors, particularly birth weight. Among neonates with the same gestational age, the incidence of ROP is higher in those "small for date". Regarding the pathogenesis of ROP, the authors outline the importance of perinatal hypoxia.
