Percent change in relative blood volume between patients with and without recurrent macular edema. We found no significant differences between the nonrecurrent and recurrent groups in the percent change in RFV in the arteries of the non-occluded and occluded regions (p = 0.525, p = 0.512, respectively). We found no significant difference in the percent alteration in RFV between the nonrecurrent and recurrent groups in the veins of the non-occluded region (p = 0.251), but we did find a significant difference in the percent alteration in RFV between the groups in the veins of the occluded region (* p = 0.005).
