Table 1 and Table 2 represent the results of the 3 temporal reproducibility exercises where the same set of fundus photographs and fluorescein angiograms was regraded annually. The results of each annual regrade were compared with the original grading. In Table 1, the intergrader agreement for the type of RVO was 93% at year 1, 96% at year 2, and 97% at year 3. The agreement for the presence of retinal thickening at the center of the macula was 97%, 98%, and 96%, respectively. The ICC for the area of retinal thickening on color photographs was 0.64, 0.39, and 0.52, respectively. The ICC for area of retinal hemorrhage was 0.87, 0.88, and 0.96, respectively. On fluorescein angiography, the ICC for area of fluorescein leakage within the grid was 0.75, 0.66, and 0.69, respectively; the ICC for area of capillary nonperfusion within the grid was 0.94, 0.97, and 0.97, respectively. In Table 2, the mean areas obtained at each annual regrade are compared with the original grade. Figure 3 represents the scatterplots comparing the 3 annual regrades with the original grade of record for area of retinal thickening, area of retinal hemorrhage, area of fluorescein leakage, and area of capillary loss.
