In the healthy controls, the inferior cpRNFL (130.07 ± 11.6 μ m) tended to be thicker than the superior cpRNFL (126.96 ± 14.6 μ m), but with marginal significance ( P = 0.079; Figure 2(a) ), whereas the superior GCIPL (86.71 ± 4.53 μ m) was significantly thicker than the inferior GCIPL (85.25 ± 4.40 μ m; P < 0.001; Figure 2(b) ).
