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.

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.

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. Our focus is M3 receptors.

It was developed to facilitate the non‐contact analysis of ocular blood flow in living eyes, utilizing the laser speckle phenomenon. PURPOSE: Innovative laser speckle flowgraphy (LSFG) enables noninvasive evaluation of retinal microcirculation and the usefulness has been reported in the field of ophthalmology. LSFG has allowed us to measure the real time changes of retinal blood flow without pupillary dilatations and contrast media. Laser speckle flowgraphy (LSFG) is a technique that quantifies blood flow based on speckle statistics.

Laser speckle flowgraphy (LSFG) allows for the quantitative estimation of blood flow in the optic nerve head, choroid, retina and iris in vivo. It was developed to facilitate the non‐contact analysis of ocular blood flow in living eyes, utilizing the laser speckle phenomenon.

EC Ophthalmology 9.8 (2018): 572-581. Relationship between Metabolic Syndrome and Ocular Microcirculation Shown by Laser Speckle Flowgraphy in a Hospital Setting Devoted to Sleep Apnea Syndrome Diagnostics Table 1 Comparison of clinical variables between in patients with and without metabolic syndrome.

We used laser speckle flowgraphy to evaluate foot blood flow in peripheral arterial disease patients before and after surgical revascularization. Materials and methods: A prospective single-center study. Laser speckle flowgraphy (LSFG) allows for the quantitative estimation of blood flow in the optic nerve head, choroid, retina and iris in vivo . It was developed to facilitate the non‐contact analysis of ocular blood flow in living eyes, utilizing the laser speckle phenomenon. Laser speckle flowgraphy (LSFG) allows for quantitative estimation of blood flow in the optic nerve head (ONH), choroid and retina, utilizing the laser speckle phenomenon.

The speckle pattern appears in accordance with blood flow velocity.1,2 Herein, we applied LSFG techniques to treat compensatory sweating (CS) (Video 1). 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 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. With laser speckle flowgraphy, the sympathetic nerve related to the sweating of various parts of the body could be identified.

Abstract Laser speckle flowmetry (LSF) is useful to assess noninvasively two-dimensional cerebral blood flow (CBF) with high temporal and spatial resolution. The authors show that LSF can image the spatiotemporal dynamics of CBF changes in mice through an intact skull.

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

2019-09-12 · Purpose: To investigate the relationship between laser speckle flowgraphy (LSFG) and optical coherence tomography angiography (OCTA) measurements of the peripapillary retina and optic nerve head (ONH) in normal eyes and eyes with primary open-angle glaucoma (POAG).

Despite success of thoracic sympathectomy (ETS), there are patients that develop postoperatively intensive sweating of the trunk. The aim of the study was to present outcomes of three of those methods: removal of the clips, clipping of T6-9, and regional abdomino-lumbar iontophoresis (RALI). Methods. Out of the group of 229 patients treated with ETS, there were 9 that Laser 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 the demarcation line after vessel dissection and reduce the incidence of anastomotic leakage (AL).

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.
