Abstract
- So far most screening protocols for retinopathy of prematurity (ROP)have used a single parameter such as chronological age or postconceptional age. We attempted to test a screening protocol for ROP using dual parameter, chronological age and postconceptional age, to determine whether it could reduce the number of screening examinations safely.We retrospectively reviewed medical records of 23 infants (43 eyes)who had undergone laser treatment for threshold ROP.Mean gestational age at birth was 28 weeks and mean birth weight was 1055 gms.The mean age at which the study infants reached threshold ROP was 10 weeks in chronological age and 38 weeks in postconceptional age.Screening examinations as early as chronological age of 7 weeks or postconceptional age of 35 weeks could detect all threshold ROP while reducing the number of unnecessary early examinations.
