Changes in Ocular Blood Flow after Ranibizumab Intravitreal Injection for Diabetic Macular Edema Measured Using Laser Speckle Flowgraphy

Figure 1

Representative composite color maps of the MBR as measured by LSFG. Red color indicates a high MBR and the blue color indicates a low MBR. To measure the MBR of the blood flow on the ONH, a circle was set around the ONH. Measurements for the retinal artery and the retinal vein were taken from sites near the ONH (within 1.5 papilla diameters). We selected in the superior region the artery and in the inferior region the vein.
