Klinisk prövning på Hypertension: laser speckle flowgraphy

2018/05/22. -May 22, 2018, Gamagori, JAPAN-. 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. Laser speckle flowgraphy (LSFG) utilizes the laser speckle phenomenon for the measurement of ocular blood flow in a noninvasive manner . LSFG provides the mean blur rate (MBR), which is proportional to blood velocity and has been used for the measurement of relative differences in blood flow in the optic nerve head (ONH) [ 18 – 20 ].

2014a, Omodaka et al. 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.

Laser speckle flowmetry The technique for LSF has been described in detail else-where (Dunn et al., 2001). Briefly, a CCD camera (Cohu, San Diego, CA, U.S.A.) was positioned above the head, and a laser diode (780 nm) was used to illuminate the skull surface in a diffuse manner. The penetration depth of the laser is approxi- 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) . LSFG is used for research on various diseases in adult patients, such as glaucoma [5, 6], retinal vein occlusion , and diabetic retinopathy .

Fluorescent Dye Labeling of Erythrocytes and Leukocytes for

One indicator of ocular blood flow is the mean blur rate (MBR) . LSFG is used for research on various diseases in adult patients, such as glaucoma [5, 6], retinal vein occlusion , and diabetic retinopathy . 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.
