Table 2: Macular thickness (\(\mu\)m) in each of the 90\({}^{\circ}\) quadrants around the macula. Regarding the nerve fiber layer in the macular and papilla areas, we found no significant differences. At the peripapillary ganglion cell layer (GCC), we found significant differences in all quadrants, with the exception of the superior and superior nasal area, for the right eye. For the left eye we only find differences in the lower quadrant.
