Method of Quantifying Size of Retinal Hemorrhages in Eyes with Branch Retinal Vein Occlusion Using 14-Square Grid: Interrater and Intrarater Reliability

Figure 2

Three representative fundus photographs of eyes with a BRVO, and the results of the retinal hemorrhage sizes measured by using the grid with 14 squares and an empty box with no grid. (a) shows three fundus photographs of eyes #7, #17, and #19 that are overlaid with the grid to measure the size of the retinal hemorrhages. (b) is a graph plotting the retinal hemorrhage size measured with the 14-square grid and with the empty box made by the three raters. Note that there is less variation between three raters when they used a grid with 14 squares than when they used the empty box.
