Fig 1.
A–F. OCT-A images. Representative OCT-A images of the different devices of the SCP (A–C) and DCP (D–F). A+D = Optovue, B+E = Canon, C+F = Heidelberg.
Table 1.
Interobserver (R1 vs. R2) intrasession reproducibility of foveal avascular zone area measurements (m1, m2, m3) of the superficial and deep OCT angiogram for the three different devices.
Table 2.
Pairwise comparison as paired t-test between the first and second (m1 vs. m2) and the first and third measurement (m1 vs. m3) and ICC values for the three different devices (R1, SCP).
Table 3.
Pairwise differences and intraclass correlation coefficient (ICC) of FAZ measurements comparing the three different devices (R1, SCP, MD = mean difference, AD = absolute difference).
Fig 2.
Regression line showing the linear relationship between the area of the FAZ measured using the Optovue device and the Canon (blue) / Heidelberg (green) devices.
Fig 3.
A–C. Bland-Altman-analysis. Bland-Altman plots showing the level of agreement for the area of the FAZ in the superficial retinal OCT-A angiogram. A: Optovue and Canon; B: Optovue and Heidelberg; C: Heidelberg and Canon. Broken line represents the mean difference; dotted lines represent the limits of agreement.
