[Occurrence of retinopathy of prematurity at the Koprivnica Hospital during 2 5-year periods].
The prevalence of retinopathy of prematurity (ROP) in the Koprivnica General Hospital among infants weighting < or = 1500 g at birth and with < or = 31 weeks of gestation, increased in the second of the two five-year periods (I 1984-1988 and II 1989-1993). In period I only one infant with ROP in stage 4 was diagnosed during hospitalization. In period II prevalence of ROP in infants with birth weight < or = 1500 g was 56.5% and in newborns whose gestational age was < or = 31 weeks it was 28.9%. The ROP group of infants had significantly lower birth weight and gestational age. Oxygen therapy and duration of stay in the incubator were significantly longer in the ROP group. Apneic spells and blood transfusions were more frequent in the ROP group of infants. Mortality of premature infants during period II was significantly lower (chi 2 = 5.95; P = 0.015), while the number of fundus examinations in the hospital significantly increased (chi 2 = 36.4; P = 1.7 x 10(-9)). In period II 7 of 13 premature infants had ROP stage 1 or 2, and 6 of them had ROP stage 3 according to the international classification of ROP. Premature infants with ROP stage 3 had significantly lower birth weights (Z = 1.86; P = 0.032) as well as gestational ages (Z = 1.71; P = 0.04), compared to premature infants with ROP stage 1 or 2. All ocular changes regressed spontaneously in infants with ROP stage 1 or 2. Outcome in infants with ROP stage 3 was as follows: 5 eyes were blind, changes regressed spontaneously in 4 eyes, while regression occurred after transconjunctival cryotherapy in 3 eyes.
