Fig. 4.

Directional light scattering captured for the parafoveal region of subject DV showing (a) three superimposed simultaneous images left (blue), upper (green) and right (red) and (b) enlarged view of the central region along with the RGB color identification of relative cone pointing directions as determined from three of the four quadrant images. In (c) the inclination vectors have been overlaid to show the local pointing obliqueness calculated using Eq. (1) with all four images thereby removing the ambiguity in the vertical direction. For the chosen section in (c) the disarray parameter equals $\tilde{\sigma }$ = 0.091 and it varies in the range of 0.078 - 0.102 for the duration of the video sequence.
