2016). The skin blood flow on both sides was compared using laser speckle flowgraphy (LSFG). 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.

The penetration depth of the laser … Purpose . To compare optical coherence tomography angiography (OCT-A) and laser speckle flowgraphy (LSFG) for the diagnosis of normal-tension glaucoma (NTG). Methods . Twenty-eight eyes of 28 patients with NTG and 25 eyes of 25 normal subjects matched for age, refractive errors, systemic blood pressure, and central corneal thickness were evaluated.

NIDEK CO., LTD., a global leader in the design, manufacturing, and distribution of ophthalmic, optometric, and lens edging equipment, is pleased to announce the launch of the LSFG-RetFlow Laser Speckle Flowgraphy. 2016-05-09 2020-09-07 2016-12-13 2020-06-23 Laser speckle flowgraphy (LSFG) is a promising candidate for such a method. LSFG is a non-invasive, real-time method that is used to measure the relative blood flow velocity in the ONH, 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) .

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. The authors show that LSF can image the spatiotemporal dynamics of CBF changes in mice through an intact skull. 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.

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). Non-invasive, real-time imaging and quantitative assessment of retinochoroidal blood flow Color coded display of blood flow allows easy clinical evaluation and analysis.

NIDEK CO., LTD., a global leader in the design, manufacturing, and distribution of ophthalmic, optometric, and lens edging equipment, is pleased to announce the launch of the LSFG-RetFlow Laser Speckle Flowgraphy. The LSFG-RetFlow is an innovative product for non-invasive, real-time imaging and measurement of ocular blood flow that will aid in the clinical evaluation of glaucoma and retinochoroidal vascular disease. The Laser Speckle Flowgraphy (LSFG-NAVI) can visualize and measure the distribution of blood flow in the human retina in a broad area from macular to the optic nerve head. The most useful feature of the instrument is the ability to non-invasively observe blood flow synchronized with the heartbeat as a series of 2D blood flow maps.
