IGF1 and retinopathy of prematurity: Consistent with the evidence that IGF-1 is as strong as predictor of ROP [98], Löfqvist, C. et al. proposed an algorithm named WINROP (weight, insulin-like growth factor I, neonatal, retinopathy of prematurity) in which IGF-I values can be used to screen for infants who might be at risk of ROP [12].
