  • Abstract
  • Look Inside

We evaluated a consecutive series of 96 infants over a 3-year period (1982-84). They weighed 1,500 g at birth and were admitted to the neonatal care unit of our hospital.

The present series consisted of two heterogenous groups. There were 33 infants who were born in our hospital (Group A) and another 63 cases who were referred to us after birth elsewhere.

There was no difference in the survival rate between the two groups. The incidence and severity of retinopathy of prematurity (ROP) were significantly higher in Group B than in A. The incidence of stage 3 and more severe ROP was strikingly high in infants with birthweight of 750 to 1,249 g belonging to Group B. The incidence and severity of ROP decreased, alongwith the increase in birthweight, rapidly in Group A and gradually in Group B.

Throughout the series, the birthweight was more significantly correlated with the rate of mortality and aggravation of ROP than the gestational period or the prematurity score P after Karaki.

We evaluated the possible role of degree of Apgar score, cyanosis and hypothermia on the occurrence and progression of ROP. Cases with hypothermia in Group B showed a high incidence of severe ROP.

Above findings indicate that transportation of pre-mature infants to neonatal care units involves inherent risks regarding the eye. We emphasize that maternal transportation is to be preferred to neonatal transporta-tion when risk factors are involved.
