Absolute values (percentage), unless stated otherwise. SD standard deviation.
IOP intraocular pressure, BCVA best-corrected visual acuity, logMAR log of the minimum angle of resolution, n sample size.
^a χ ²-test (Fisher´s exact test).
^b Student´s t-test for independent samples with normal distribution (Shapiro-Wilk test was used to assess normality of distributions).
^c Mann–Whitney U-test without normal distribution.
* Laser peripheral iridotomy was performed in eyes with slightly narrow angles.
