Data are means ± SD. IOP, intraocular pressure. The P values of the repeated-measures ANCOVA with baseline as the covariate are given.

Supine and prone measures were significant at the α = 0.01 level with Bonferroni pairwise comparisons within a given time point.

^†

Significant difference. The factors evaluated in the model were change with time and differences between postures.
