Mapping the Structure-Function Relationship in Glaucoma and Healthy Patients Measured with Spectralis OCT and Humphrey Perimetry

Figure 3

(a) Nonparametric regression between the regions of the inferior hemifield (1–4 inferior visual field, IVF) and superior hemigrid (1–5 superior macula, SM) obtained through factor analysis and that showed significant correlation according to Pearson’s correlation coefficient (shown at the top right of the graphics) in the glaucoma group. Values of threshold sensitivity (decibels) are represented in the y-axis and values of macular thickness (microns) in the x-axis. (b) Graphic scheme of the Pearson correlations between the regions obtained though factor analysis of the inferior hemifield (1–4) and factor analysis of the superior hemigrid (1–5) in glaucoma cases. Regions that showed significant correlations are represented with the same color. Correlations with are represented by colored thin strips.
