Figure 2 Optical coherence tomography (OCT) images of vertical retinal sections of the fovea obtained at the final visit. Macular oedema secondary to branch retinal vein occlusion (BRVO) is resolved completely in all images. The retina affected by BRVO is shown on the left in all images. Status of the third high reflectance band (HRB) was evaluated with monochromatic (greyscale) OCT images. (A) The third HRB is well preserved in the fovea (arrow). (B) The third HRB is well preserved in the unaffected retina (arrowhead), but is deteriorated in the fovea (arrow) and affected retina. (C) The third HRB is discontinuous in the fovea (arrow), while it is clearly detected in unaffected retina. RPE, retinal pigment epithelium.
