Figures & data
Figure 1 Case 1: fundus photography shows three equidistant planes defined as plane 1, plane 2, and plane 3.
Figure 2 Case 1: the average of three measurements (542, 516, and 544 μm) was taken as the ALCSD (534 μm) at the superior plane.
Figure 3 Case 1: the average of three measurements (412, 585, and 592 μm) was taken as the ALCSD (529.6 μm) at the mid-horizontal plane.
Figure 4 Case 1: the average of three measurements (542, 508, and 534 μm) was taken as the ALCSD (528 μm) at the inferior plane.
Figure 5 Case 2: the average of three measurements (393, 392, and 375 μm) was taken as the ALCSD (386.6 μm) at the superior plane.
Figure 6 Case 3: the average of three measurements (643, 616, and 610 μm) was taken as the ALCSD (623 μm) at the inferior plane.
Figure 7 Case 4: poor visibility of LC due to small cup (cup/disc ratio: 0.06).
Figure 8 Case 5: poor visibility of LC (masked by the shadow of the central vessel trunk).
