Figure 4

Prevalence of astigmatism (≥ 1.00 diopter (D), Figures 4A, 4B and 4C) and high astigmatism (≥ 2.00 D, Figures 4D, 4F, and 4G) at 6 and 9 months corrected and at 2 and 3 years postnatal age as related to severity of retinal residua of ROP in each eye. Black bars indicate prevalence in eyes that underwent treatment at high risk prethreshold ROP; gray bars indicate prevalence in eyes with high risk prethreshold ROP that were managed conventionally. Numbers above each bar indicate the number of eyes that provided data at each age.
