    Abstract:
    The authors investigate the changes of chorioretinal blood flow using laser speckle flowgraphy (LSFG) in efficacy of treatment. Intravitreal bevacizumab was injected in a patient with proliferative diabetic retinopathy. LSFG measures the relative velocity index of erythrocytes (mean blur rate) in a previously confirmed area, with neovascularization elsewhere (NVE), neovascularization of the disc (NVD), and without neovascularization. The authors compared mean blur rate before and after bevacizumab injection in each area. In LSFG images, regression of blood flow was observed at the area of neovascularization sequentially as the change of color pattern. Finally, decrease of the mean blur rate of an average 32.7% was observed in the NVE area. Similarly, a reduction of 31.9% of mean blur rate was observed in the NVD area. However, in the area of without neovascularization, reduction of mean blur rate was not observed. This suggested the useful possibility of measuring chorioretinal blood flow changes by drug intervention using LSFG analysis.
