Univariate and multivariable linear regression analyses were performed with ACV as the dependent variable and age, gender, AL, IOP, PD, LV, IV, and ACW as independent variables.
CI = confidence interval, AL = axial length, IOP = intraocular pressure, PD = pupil diameter, LV = lens vault, IV = iris volume, ACW-H = anterior chamber width measured in the horizontal direction, ACW-V = anterior chamber width measured in the vertical direction, and ACD = anterior chamber depth.
