Mean RNFL thickness of subgroups classified by the location of the inferior peak thickness after correction for ocular cyclotorsion (A, B and C) and comparison of interocular RNFL thickness differences between the subgroups (D and E).

<p>A. Mean RNFL thickness of group 4 (subjects in whom the corrected location point of the inferior peak was ≤ 202.16 in 1 or both eyes, n = 62). B. Mean RNFL thickness of group 5 (subjects in whom the corrected location point of the inferior peak was between 202.16 and 217.75 in both eyes, n = 145). C. Mean RNFL thickness of group 6 (subjects in whom the corrected location point of the inferior peak was ≥ 217.75 in 1 or both eyes, n = 53). D. The mean fractional interocular RNFL thickness differences. E. The mean absolute interocular RNFL thickness differences. [Straight line, right eye; dotted line, left eye; red line, group 6; black line, group 5; blue line, group 4; arrow heads, the mean locations of the superior peak RNFL thickness; gray zone, the area where the difference is statistically significant (P<0.05 by Kruskal Wallis test)](TEMP = Temporal, SUP = Superior, NAS = Nasal, INF = Inferior).
