Incidence of retinopathy of prematurity among infants weighing 2000 g or less at birth. 1987

P Archambault, and J E Gomolin

A retrospective study was carried out to determine the incidence of retinopathy of prematurity (ROP) among 157 neonates who weighed 2000 g or less at birth and who were examined at a referral centre for critically ill newborns between January 1983 and December 1985. Overall, 24 cases (15%) of ROP were detected, 18 (75%) among neonates with a birth weight of 1000 g or less. The incidence of ROP was more than eight times higher among neonates in this birth weight category than among those who weighed between 1001 and 2000 g. Grade I ROP accounted for 16 cases (67%), grade II for 7 cases (29%). Only one case (4%) of grade IV ROP was diagnosed, in an infant who weighed 1020 g at birth.

D012178	Retinopathy of Prematurity	A bilateral retinopathy occurring in premature infants treated with excessively high concentrations of oxygen, characterized by vascular dilatation, proliferation, and tortuosity, edema, and retinal detachment, with ultimate conversion of the retina into a fibrous mass that can be seen as a dense retrolental membrane. Usually growth of the eye is arrested and may result in microophthalmia, and blindness may occur.

D012189	Retrospective Studies	Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
