  1. tROP, retinopathy of prematurity with laser treatment; srROP, spontaneously regressed retinopathy of prematurity; HC, healthy controls; pRNFL, peripapillary retinal nerve fiber layer; GCIPL, ganglion cell-inner plexiform layer; SE = standard error, CI = confidence interval.
  2. Values are shown as mean ± standard deviation.
  3. aP value was calculated by multivariate linear regression after adjusting for age and Bonferroni correction multiplied by 3 with 3 subgroups.
  4. In each group comparison, Bonferroni correction was performed by multiplying p value by 8 due to multiple testing of outcomes.
  5. Boldface indicates statistical significance.
