title: New Predictors for Advanced Retinopathy of Prematurity among Neonates in Tehran/Iran.
abstract: OBJECTIVE
  Since a new epidemic (third wave) of retinopathy of prematurity (ROP) sensed throughout the world in recent years, we aimed to assess newer risk factors for advanced ROP which needs treatment in Iranian neonates as a new target output of various neonatal care for this serious disease of newborn infants especially those born prematurely.
  
  
  METHODS
  In an analytic cross-sectional study all neonates <1500 g birth weight and/or <32 weeks gestational age admitted to our NICU as a tertiary level intensive care unit in Milad Hospital, Tehran, Iran during June 2006-June 2007 were included. All data were extracted from medical records and compared in two groups with or without treatment.
  
  
  RESULTS
  Seventy one neonate infants entered our study. Twelve neonates (16.9%) progressed to advanced ROP. Final multivariate analysis model revealed that mean leukocyte counts during first 14 days of life (P=0.04), transfusions number (P=0.01) and hypocapnic episodes during first 14 days of life (P=0.02) were significantly different between the two groups of infants independently, even after simultaneous adjustment.
  
  
  CONCLUSIONS
  Based on our findings, more amenable risk factors should be approached regarding more careful modulation of such overlooked risk factors which may lessen the burden of prematurity.
