  1. Retinopathy of prematurity in infants weighing 1000-1499 g at birth.

    Article - En anglais


    To review the incidence and severity of retinopathy of prematurity (ROP) in infants with birthweights 1000-1249 g and 1250-1499g, to establish whether the upper weight limit for routine ophthalmological examination might safely be lowered.


    Prospective cohort study of infants born between 1 January 1977 and 31 December 1992 cared for in the neonatal nurseries at the Royal Women's Hospital, Melbourne.

    Data were retrieved on 1373 infants who survived their initial hospitalization.

    They comprised 657 with birthweights 1000-1249 g (group 1) and 716 with birthweights 1250-1499 g (group 2).

    There were 76 outborn infants in group 1 and 97 in group 2. Results : In group 1, ROP was detected in 14.6% (96/657) and severe ROP (bilateral stage 3-5) in 5.0% (33/657).

    Five (0.8%) children required surgical intervention (reaching threshold disease) ; following surgery, one was legally blind, one had severely impaired vision, and the other three had near-normal vision.

    Another child was blind ; he was born at 28 weeks gestational age with a birthweight of 1170g, and was transferred to a Level II hospital at 9 weeks chronological age with no detectable retinopathy.

    He returned 1 year later totally blind with detached retinae (grade 5 ROP).


    In neonatal units with similar rates of ROP and visual outcome, routine ophthalmological examination in the neonatal nursery of infants weighing more than 1249 g at birth is probably unnecessary.
