Laser speckle flowgraphy (LSFG) is an ocular imaging modality that quantifies OBF in the ONH based on the speckle phenomenon. It has gained favor owning to the reproducibility of its noninvasive measurements in human and animal applications6,7,8,9. An essential parameter measured by LSFG is...
Laser speckle flowgraphy (LSFG) enables noninvasive quantification of the retinal circulation in glaucoma patients. In this study, we tested the intrasession reproducibility of LSFG-NAVI, a modified LSFG technique. Sixty-five eyes from 33 subjects (male (M):female (F) = 17:16) with a mean...
Bowel blood perfusionLaser speckle flowgraphyLaser speckle imagingAnastomotic leakagePurposeLaser speckle flowgraphy (LSFG) is a noninvasive method for quantitative evaluation of blood flow using the mean blur rate (MBR) as the blood flow index. We investigated whether LSFG can intraoperatively detect...
