Comparison of imaging measurements to local visual field results. (a) Raphe gap as a function of averaged field loss. (b) Bundle index as a function of TD. (c) The RNFL thickness as a function of TD. (d) The GCC thickness as a function of TD. Blue circles represent data of the controls and the red triangles represent data of the patients with glaucoma. The two groups in (a, b, d) are significantly different, with P value less than 0.0001 in (a), equal to 0.0018 in (c), and (d), with P values less than the α value 0.0125.
