Prevalence of retinopathy of prematurity in Switzerland

Abstract

On the basis of an international inquiry I covering prematures of < 1000 g birthweight born between 1974 and 1986, the following Swiss figures ar known: 228 of 525 registered prematures survived (41%) and 151 were examined by an ophthalmologist (66 % of survivors). 50 children (33% of survivors) had some stage of ROP. As of December 31, 1984, 262 children aged 7-16 years were being schooled in Swiss educational institutions for the visually handicapped. 32 (12%) of them had severe stages of ROE 22 of these (69%) were totally blind. The 22 blind children with ROP corresponded to 25 % of all blind children (n = 89) in these institutions. One child had been born at 34 weeks gestational age, all others at 32 or less. No child had a birthweight of more than 2000 g2. These figures are likely to be an underestimate, since the populations being cared for in institutions for severely affected children with multiple handicap were not investigated. Blind children living at home were also not considered. Over the last 10 years, 702 newborns at risk for ROP born in Berne were examined by an ophthalmologist. 165 (23.5%) had some stage of ROP (stage: 1:11%, stage 2: 8%, stage 3: 3%, stage 4: 0,7%, stage 5: 0,7%). 2 children between 1500 und 2000g birth weight had stage 3 disease, no ROP-stage higher than 2 occured in babies with birth weights above 2000 g. The continuous survey of the Swiss Neonatology Group on prematures
