The data are presented as means ± standard deviations. Differences in values before and after eye treatment were determined using analysis of variance with the Wilcoxon test. The ratios calculated based on the pretreatment values and values based on the ratios were presented in the square brackets. IOP: intraocular pressure; MOPP: mean ocular perfusion pressure; MBP: mean blood pressure; MBR_T: mean blur rate in the issue area of the optic disc; AU: arbitrary unit; BOS: blowout score; ATI: acceleration time index; BOT: blowout time.
