The surgeon, Dr. Yamamoto, used laser speckle flowgraphy to determine from which level of the sympathetic chain the compensatory sweating signals were originating in 8 patients. The culprit ganglion levels were then removed. There was total resolution of compensatory sweating and the patient's were "very satisfied" with the results.

With laser speckle flowgraphy, the sympathetic nerve related to the sweating of various parts of the body could be identified. The treatment of compensatory sweating on the back, chest, and stomach was previously considered to be difficult; however, compensatory sweating is demonstrated to be treatable with this technique.

When intraoperative monitoring with laser speckle flowgraphy indicated the position of compensatory sweating by electrical stimulation of the sympathetic ganglion, ganglionectomy was performed. The surgeon, Dr. Yamamoto, used laser speckle flowgraphy to determine from which level of the sympathetic chain the compensatory sweating signals were originating in 8 patients. The culprit ganglion levels were then removed. 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.

The ultrasonography-guided method was successful in detecting the cannula and the blood vessel, and the HA filler was safely injected into a deep region. Using LSFG, a difference in skin blood flow between the 2 methods was detected.

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

2018/05/22-May 22, 2018, Gamagori, JAPAN- 13 Dec 2016 Purpose To assess the feasibility and reliability of Laser Speckle Flowgraphy ( LSFG) to measure ocular perfusion in a sample of healthy white Laser speckle flowgraphy (LSFG) is a promising technique for the exploration of ocular perfusion in a clinical setting given its patient friendliness and the real-time Laser speckle flow graph (LSFG) devices enables the noninvasive evaluation of skin blood techniques to treat compensatory sweating (CS) (Video 1). CASE REPORT S. Use of laser speckle · flowgraphy in ocular blood flow resear Methods. Eight patients with severe compensatory sweating were treated by observing blood perfusion of the skin with laser speckle flowgraphy, which determines Laser speckle flow graph (LSFG) devices enables the noninvasive evaluation of skin blood perfusion.

2016-12-13 · CONCLUSIONS: LSFG represents a reliable method for the quantitative assessment of ocular blood flow in white subjects. Our data affirms that the LSFG-derived variables FR and BOT may be useful biomarkers for age-related changes in ocular perfusion. PMCID: PMC5154568.

Using LSFG, a difference in skin blood flow between the 2 methods was detected.

However, 10% to 15% of patients do not benefit from this intervention. No additional procedure has been developed for this disorder.

18 This technique has been used to study optic nerve head blood flow, 19 20 but when retinal areas are measured the signal contains proportions from both retinal and choroidal circulations. 18 21 PURPOSE: To compare glaucoma severity with ocular microcirculation, measured with either laser speckle flowgraphy (LSFG) or optical coherence tomography angiography (OCTA). METHODS: We retrospectively studied 82 eyes of 82 open-angle glaucoma (OAG) patients who underwent same-day LSFG and OCTA examinations, with 20 eyes of 20 healthy subjects The body still needs to sweat to thermoregulate. Also, the use of laser speckle flowgraphy doesn't make sense. It checks the vasodilation of blood vessels.

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.

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). The aim of this study was to assess the feasibility of ocular b … Recently, ganglionectomy using application of laser speckle flow graph has been evaluated for the treatment of compensatory sweating. We report our results of ganglionectomy for facial blushing as a redo surgery. Abstract Laser speckle flowmetry (LSF) is useful to assess noninvasively two-dimensional cerebral blood flow (CBF) with high temporal and spatial resolution.

Laser speckle flowgraphy (LSFG) can be used to noninvasively measure ocular blood flow [1–4]. One indicator of ocular blood flow is the mean blur rate (MBR) [ 5 ]. LSFG is used for research on various diseases in adult patients, such as glaucoma [ 5 , 6 ], retinal vein occlusion [ 7 ], and diabetic retinopathy [ 8 ].

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 Laser speckle flowgraphy (LSFG) allows for the quantitative estimation of blood flow in the optic nerve head (ONH), choroid and retina in vivo, utilizing the laser speckle phenomenon.

Introduction. Laser speckle flowgraphy (LSFG) uses the laser speckle phenomenon in estimating ocular circulation in living eyes in a noninvasive manner.1 The current LSFG instrument yields the mean blur rate (MBR), which is a quantitative index of blood flow velocity in target tissues.

METHODS: We retrospectively studied 82 eyes of 82 open-angle glaucoma (OAG) patients who underwent same-day LSFG and OCTA examinations, with 20 eyes of 20 healthy subjects The body still needs to sweat to thermoregulate. Also, the use of laser speckle flowgraphy doesn't make sense. It checks the vasodilation of blood vessels. The eccrine glands are stimulated by acetylcholine in the dermal layer of skin to cause a majority of sweating.
