As shown in
Table 4, the mean, superior and temporal CT, central mean, temporal, pericentral mean, inferior and nasal RPC VD, and temporal CVI decreased with the increase of AL (
P < 0.001). In contrast, the mean and temporal RNFL thickness increased (
P < 0.001). Group 3 demonstrated a lower central superior, inferior and nasal, pericentral superior and temporal RPC VD than those observed with groups 1 and 2 (
P ≤ 0.001). Group 1 had a larger inferior and nasal CT value, mean, superior, inferior, and nasal CVI than those observed from groups 2 and 3 (
P < 0.001). According to the univariate and multivariate analyses, SE was significantly correlated with mean and temporal RNFL thickness (
P < 0.001); mean, superior, temporal, and inferior CT (
P < 0.001,
P = 0.013,
P < 0.001, and
P = 0.006, respectively); central mean and temporal, pericentral mean, temporal (
P < 0.001), and nasal RPC VD (
P = 0.041); and mean and temporal CVI (
P <0.001). The AL was associated with the mean and temporal RNFL thickness (
P <0.001); mean, temporal, and inferior CT (
P < 0.001,
P < 0.001, and
P = 0.028, respectively); central mean; temporal and nasal and pericentral mean; temporal RPC VD (
P < 0.01); inferior RPC VD (
P = 0.032); and mean, temporal (
P < 0.001), and nasal ONH CVIs (
P = 0.013,
