Figure 2.

Diffusion results in Argus II and healthy control subjects. (A) Images (b = 0) of subject A2 obtained during DWI displaying artifact around the right implanted eye (following eddy correction of the data). (B) Fractional anisotropy (FA) computed from subject A2's DWI data overlaid with color-coded principal diffusion tensor directions. Red arrows indicate location of the local artifact resulting from the presence of the device implanted in the subject's right eye. (C) Automatically reconstructed retinofugal tract from optic chiasm to V1 based on the DWI data obtained from the two Argus II subjects using our custom procedure (see Materials and Methods). (D) Similarly reconstructed retinofugal tract in two representative HCP control subjects for comparison. Right brain hemisphere is on the side of the image indicated by "R."
