The data are given as mean ± SD; values in bold are statistically significant (). AU: arbitrary units; CCT: central corneal thickness; IOP: intraocular pressure; MBR: mean blur rate; MD: mean deviation; MOPP: mean ocular perfusion pressure; PSD: pattern standard deviation; SE: spherical equivalent.
