Severe retinopathy of prematurity in infants from the southern regions of Sweden

We studied children born in 1986–1989 with severe retinopathy of prematurity (ROP) defined as stage 3 "plus" or more. Sixteen children from the southern and central areas of Sweden were identified and 15 of these were referred to Orebro Medical Center Hospital for surgical treatment of ROP. The incidence of severe ROP was estimated as 0.8 per 10000 newborns per year. All children were born before 29 weeks' gestation and weighed less than 1310 g; they also needed ventilatory support for a long time. The overall neonatal morbidity was high. A model for eye examination in premature newborns is suggested.
