ANALYZING TOMOGRAMS
• Significance Map
From left to right, 10 x 10 grid comparison maps covering 6mm x 6mm area of RNFL, GCL+ and GCL++
are shown. The comparison result is displayed with the color in the legend placed in the right. The back-
ground image is red free image.
• Average Thickness
From left to right, three average thicknesses of RNFL, GCL+ and GCL++ are shown. The top is "Superior"
which means average in the upper half area, the middle is "Inferior" which means average in the lower
half area, and the bottom is "Total" which means average in the all area. (This area is 6mm x 6mm
square). Each average thickness is compared to the normative data and displayed with the color in the
legend placed in the right.
• Asymmetry Map
From left to right, subtraction thickness maps covering 6mm x 6mm area of RNFL, GCL+ and GCL++ are
shown. The subtraction is performed between two points which symmetrically lie with respect to the cen-
ter horizontal line. In the upper half, the value in each point is calculated such that thickness of the point is
subtracted from the thickness of the corresponding line-symmetry point in the below and vice versa. Blue
color means that the thickness of the point is thinner than that of the corresponding point.
