Deficit in dark adapted peripheral threshold (Δ log DAT) plotted as a function of deficit in post-receptor sensitivity (Δ log σ) in preterm subjects with a history of no ROP (top), mild ROP (middle), and severe ROP (bottom). The circles represent data from individual preterm subjects (open circles – infants; filled circles – older subjects). The triangles indicate the mean (±SEM) for term born 10-week old infants (open) and adults (filled). The mean normal adult value is at coordinates (0,0). The solid line has a slope of 1.
