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. Compared to other laser-based techniques (i.e., laser Doppler velocimetry and flowmetry), the LSFG measurement

In recent years, laser speckle flowgraphy (LSFG) has been introduced as a non-invasive, easy to perform, and reliable means of measuring retinal blood flow , , , . The principles of LSFG have been well described . Briefly, when the retina is illuminated with a diode laser, a speckle pattern of the retina appears due to the interference of the light scattered by the movements of the erythrocytes within the retinal vessels.

Email ryousuke0218@hotmail.co.jp. 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). 2021-03-25 2014-09-24 2021-03-25 2020-06-22 Aizawa N, Yokoyama Y, Chiba N, et al.

Laser Speckle Flowgraphy Blood Flow Measurements. Measurements were obtained using the LSFG system (LSFG-NAVI; Softcare Co, Ltd, Fukuoka, Japan) . As has been previously described, 14,15 use of the LSFG technique makes it possible to measure the optic disc. 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.

Laser speckle flowgraphy has contributed to our understanding of the association of ocular BF with glaucoma pathophysiology by showing that MBR is associated with structure and function in glaucoma (Aizawa et al. 2014a, Omodaka et al. 2016).

Vascular and tissue area mean blur rate (MBRV and MBRT), measured using laser speckle flowgraphy (LSFG), was significantly lower in the 32 included ODD Laser speckle flowgraphy enables the in vivo quantification of circulation in the optic nerve head (ONH), choroid, and retinal vessels and can reveal the circulatory 12 Nov 2018 Laser speckle flowgraphy is a new method that enables the rapid evaluation of foot blood flow without contact with the skin. We used laser Laser speckle flow graph (LSFG) devices enables the speckle phenomenon is an interference event observed flowgraphy in ocular blood flow research.

Laser speckle flowgraphy (LSFG), which uses the laser speckle phenomenon to detect and quantify the motion of blood cells in the ocular fundus, is one of the most promising candidates in this search. 5–23 Moreover, a recently developed measurement parameter derived from LSFG, the mean blur rate (MBR), can serve clinically as a quantitative and reproducible index of retinal blood cell

PURPOSE: To assess the feasibility and reliability of Laser Speckle Flowgraphy (LSFG) to measure ocular perfusion in a sample of healthy white subjects and to elucidate the age-dependence of the parameters obtained. ONH blood flow, represented by the mean blur rate (MBRT) and pulse waveforms, was measured using laser speckle flowgraphy before and 1 and 3 months after treatment. Three months after treatment, IOP exhibited a significant decrease (p < 0.05).
