Pairwise comparisons were carried out by LSD method, and pairs with significant P values were shown by superscript alphabets as follows: a: before PI – non-mydriatic vs. before PI – mydriatic; b: after PI – non-mydriatic vs. after PI – mydriatic; C: before PI – non-mydriatic vs. after PI – non-mydriatic; d: before PI – mydriatic vs. after PI – mydriatic.
AC, anterior chamber; D, diopter; I, inferior; IOP, intraocular pressure; Km, mean keratometry; PI, peripheral iridotomy; N, nasal; S, superior; T, temporal.
Calculated with repeated-measures ANOVA test.
No difference was found in any pair-wise comparison using Bonferroni correction.
