Timely recognition and treatment of retinopathy of prematurity (ROP) is the cornerstone to improving chances for preserving vision in premature infants. The window of time when treatment must be offered is short, sometimes lasting only a few days, but the window is often predictable. Onset and evolution of ROP is timed more to the gestational age than the chronological age of premature infants. The median age when infants could develop stage 3 disease, for example, is 36.6 weeks.1
