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

Figure 4

Changes in the retinal hemorrhage area over the time in an eye with BRVO. The retinal hemorrhage area was measured by the three raters using a grid with 14 squares at the initial visit (0) and at 2, 4, 6, 8, and 10 months after the initial visit. Intravitreal ranibizumab was injected at the initial visit. Fundus photographs at each time point are shown in (a), and values of retinal hemorrhage size measured by each three raters and averaged values are plotted in (b).
