Statistically significant P values in multivariate regression analyses are highlighted as bold.
BCVA, best-corrected visual acuity; BP, blood pressure; CT, choroidal thickness; IOP, intraocular pressure; logMAR, logarithm of the minimum angle of resolution; RT, retinal thickness; SE, spherical equivalent.
