PD = pupil diameter, CCT = central corneal thickness, IT750 = iris thickness measured at 750 μm from the scleral spur, IT2000 = iris thickness measured at 2000 μm from the scleral spur, ITM = maximal iris thickness, ICURV = iris curvature, TISA500 = trabecular–iris space area at 500 μm from the scleral spur, TISA750 = trabecular–iris space area at 750 μm from the scleral spur, ICC = intraclass correlation coefficient, CI = confidence interval
