AUC, area under the receiver operating characteristic curve; LB, lower bound (of variance function confidence interval); UB, upper bound (of variance function confidence interval).

^*Weighted mean and sectoral parameters are total retinal thickness measurements. Weighted RNFL is the weighted mean RNFL thickness measurement. Weighted means are calculated across the entire circle shown in Figure 4. Unweighted mean and RNFL compares unweighted mean retinal thickness and RNFL thickness TD-OCT variables with weighted SD-OCT variables, because unweighted SD-OCT variables are not available.

^†RTVue OCT.

^‡Stratus OCT.

^§TD-OCT AUC minus SD-OCT AUC.

^¶Significance level of difference.
