Figure 8. Visual function and ROP

A: The growth curve summarizes the developmental increase in human rhodopsin. ROP has its onset just as the curve begins to increase rapidly. B: The mean and prediction limits for D 10-30 in normal infants; the adult value of zero is reached by age 6 months. C: Sample ERG records from 10-week-old infants. The vertical scale is in log scotopic troland seconds. The downward deflections in the records are the a-waves (arrow). The difference between records from the infant with mild ROP and the normal subject are conspicuous. D: The a-waves are displayed on an expanded time scale. The dashed lines represent the Lamb & Pugh model fitted to the ERG a-waves. S (rod cell sensitivity) is lower in ROP subjects. E: The mean values of S for "No ROP" and "ROP" subjects are shown as percent of normal for age. The means differ significantly (re-plotted from Fulton et al, 2001).
