There was total resolution of compensatory sweating and the patient's were "very satisfied" with the results. Laser speckle flowmetry (LSF) has been used to measure blood flow in skin, and retina, among many other tissues (Briers, 2001; Ruth, 1990; Yaoeda et al., 2000). LSF provides full-field analysis of time-varying speckle contrast fluctuations, and therefore, real-time two-dimensional CBF imaging, a clear advantage over laser-Doppler scanning techniques. 2016-12-13 · CONCLUSIONS: LSFG represents a reliable method for the quantitative assessment of ocular blood flow in white subjects.

Shemanski and others published Commentary: Don’t sweat the compensatory sweating | Find, read and cite all the research you need on ResearchGate 2000-06-01 · Laser speckle flowgraphy is also a noninvasive technique that can measure real-time, two-dimensional relative blood flow velocity of ocular microcirculation using the laser speckle phenomenon.3, 4 The purpose of this study is to compare blood flow indexes, as measured by laser speckle flowgraphy and scanning laser Doppler flowmetry, in the optic nerve head of normal volunteers. Laser speckle flowgraphy (LSFG) utilizes the laser speckle phenomenon for the measurement of ocular blood flow in a noninvasive manner . LSFG provides the mean blur rate (MBR), which is proportional to blood velocity and has been used for the measurement of relative differences in blood flow in the optic nerve head (ONH) [ 18 – 20 ]. A new method is demonstrated to visualise the microcirculation map of the human retina using a dynamic laser speckle effect. The retina is illuminated with a diode laser spot through a retinal camera, and its speckle image is detected by an area sensor.

There was total resolution of compensatory sweating and the patient's were "very satisfied" with the results. Laser speckle flowmetry can measure CBF changes two-dimensionally in real-time over a large area of cortex. Its spatial resolution is determined by the laser wavelength, the quality of the optics, the optical properties of the tissue, and the amount of pixel averaging to estimate the speckle contrast. Laser speckle flowgraphy (LSFG) is a noninvasive technique that can measure relative blood flow velocity in the optic fundus contributed by the ophthalmic artery, the main first branch originating from the internal carotid artery (ICA).

A new method is demonstrated to visualise the microcirculation map of the human retina using a dynamic laser speckle effect. The retina is illuminated with a diode laser spot through a retinal camera, and its speckle image is detected by an area sensor. The output signal from the sensor is digitised, and the data for more than a hundred scannings of the speckle image are stored in a mass image

Thoracoscopic ganglionectomy with laser speckle flowgraphy effectively treats compensatory sweating. Compensatory sweating should no longer limit the use of sympathectomy to treat primary hyperhidrosis.

The basic technology and clinical applications of LSFG-NAVI, the updated model of LSFG, are summarized in this review. For developing a commercial version of LSFG, the special area sensor was replaced by the ordinary charge Twenty-four eyes of 24 subjects with BRVOME were treated with the intravitreal injection of ranibizumab (IVR) for at least 6 months. We measured mean blur rate (MBR) in the optic nerve head (ONH) and vessel density (VD) in the macula with laser speckle flowgraphy and optical coherence tomography angiography, respectively. The moorFLPI-2 blood flow imager uses the laser speckle contrast technique to deliver real-time, high-resolution blood flow images, providing outstanding performance in a wide range of pre-clinical and clinical research applications.
