Laser speckle flowgraphy is a noninvasive, contact-free modality that is easy to implement, and beat strength of skin perfusion is a useful indicator of foot circulation during the perioperative period. Further analysis with a larger number of cases is necessary to establish appropriate clinical use. 2016-12-13 · 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. 2016-12-13 · In recent years, Laser Speckle Flowgraphy (LSFG) has rapidly arisen as a promising technique for the two-dimensional assessment of ocular blood flow in humans. LSFG enables non-invasive, patient- and examiner-friendly quantitative estimation of perfusion at the ONH, retina and choroid, simultaneously, in less than 5 seconds. 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.

Laser speckle flowgraphy may offer a noninvasive method of assessing ocular blood flow in patients with central retinal vein occlusion (CRVO), according to a prospective study published in the 2020-06-23 · Using laser speckle flowgraphy, investigators aimed to determine the relationship between blood flow in retinal vessels and capillaries, blood flow in cervical arties, and the development of retinopathy in patients with type 2 diabetes. 2017-07-24 · Laser speckle flowgraphy. Laser speckle flowgraphy (LSFG) is a non-invasive modality that enables measurement of ocular blood flow. The LSFG system uses a regular charge-coupled-device camera to capture a frame size of 750 x 360 pixels at a temporal frame rate of 30 frames per second. 一方，laser speckle flowgraphy（LSFG）は，わが国発信の眼底血流測定機器である 6）（図1a）。. 開発当初は，1回で眼底を走査する領域は1mm×1mmと狭小であったが，現在では8.6mm×4.6mm（画角21°）までに拡大した（図1b）。. 現行型LSFG-NAVI（ソフトケア社/NIDEK社）では，臨床医の要望に合致したさまざまな解析ソフトを搭載した，独自性の高い血流解析装置に進化している。.

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.

The basic technology and clinical applications of LSFG-NAVI, the updated model of LSFG, are summarized in this review. 2004-07-01 2018-11-12 laser speckle flowgraphy. Hideki Chuman*, Takako Hidaka, Nobuhisa Nao-i Department of Ophthalmology, Faculty of Medicine, University of Miyazaki, Japan Accepted on October 16, 2017 Keywords: Laser speckle flowgraphy, orbital tumors, optic disc blood flow. Introduction Arterial supply to the orbit is complex and makes various 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).

It was developed to facilitate the non‐contact analysis of ocular blood flow in living eyes, utilizing the laser speckle phenomenon. 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). 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. Laser speckle flowmetry (LSF) is useful to assess noninvasively two-dimensional cerebral blood flow (CBF) with high temporal and spatial resolution.
