Abstract

The demand for more precise microcirculation is rising. In the retina, microcirculation control is crucial in optic nerve head (ONH) surgeries or diabetic retinopathy surgery. Hence, novel techniques for examination of the blood flow were developed, including laser speckle flowmetry (LSF), which is based on the light scattering principle. LSF has already found many applications. However, some challenges still require further research on this method.
