Thickness measurements in volume (mm³) of the outer ring comparing each retinal layer separately between the 30 degree and the 55 degree lens.

Outer Ring	30° Lens (Mean ± SD)	55° Lens (Mean ± SD)	r (Spearman Rho)
RNFL	0.19 ± 0.03	0.19 ± 0.04	0.890*
GCL	0.2 ± 0	0.2 ± 0.02	0.895*
IPL	0.16 ± 0.01	0.16 ± 0.01	0.899*
INL	0.18 ± 0.01	0.18 ± 0.01	0.853*
OPL	0.14 ± 0.01	0.15 ± 0.01	0.850*
ONL	0.32 ± 0.04	0.34 ± 0.08	0.969*

^*Correlation is significant at the 0.01 level. The last column shows how well the lenses correlate using Spearman Rho calculation.
