Laser speckle flowgraphy (LSFG) is a technique that quantifies blood flow based on speckle statistics. 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

Abstract. 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 facil

LSFG allows the monitoring of transient changes in skin blood perfusion in response to electrical stimulation of a dermatome's corresponding sympathetic nerve and ganglion. 1 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 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.

It was developed to facil Analysis of Retinal Blood Flow by Laser Speckle Flowgraphy in a Case With Central Retinal Vein Occlusion After Radial Optic Neurotomy. Investigative Ophthalmology & Visual Science, 2008, 49.13: 4274-4274.

Methods: This study included 31 eyes of 31 healthy, non-smoking subjects aged between 19 and 74 years.

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).

Purpose: To compare the retinal blood flow velocity using laser speckle flowgraphy (LSFG) and a retinal function imager (RFI) in healthy Japanese subjects. Methods: This study included a total of 15 eyes of 15 healthy Japanese subjects (mean age, 41.7 ± 17.0 years).

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 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. 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 the quantitative estimation of blood flow in the optic nerve head, choroid, retina and iris in vivo.

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).

In the present study, we investigated a novel technique to measure CBF based on laser speckle flowgraphy (LSFG) in healthy subjects. Methods: This study included 31 eyes of 31 healthy, non-smoking subjects aged between 19 and 74 years. A commercial LSFG instrument was used to measure choroidal vessel diameter (CVD) and relative flow volume (RFV

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.

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.
