IUGR infants, but not SGA infants have more severe ROP. No significant association was observed between the worst stage of ROP and SGA status (AGA n = 300, SGA n = 43; p = 0.879 by Chi-square). However, there was a significant association observed between the worst stage of ROP and IUGR (non-IUGR n = 257, IUGR n = 86; p < 0.0001 by Chi-square) with a higher proportion of IUGR infants than non-IUGR infants in stage 1 (non-IUGR: 13.33%, IUGR: 14.77%), stage 2 (non-IUGR: 7.78%, IUGR: 29.07%) and stage 3 disease (non-IUGR: 6.61%, IUGR: 19.77%), and a higher proportion of non-IUGR infants with no ROP (stage 0) than IUGR infants (non-IUGR: 72.94%, IUGR: 35.23%).
