2016-12-13 2018-12-01 Laser speckle skin blood flow (LSFG-SKIN) will be recorded in normal subjects and in patients with disorders affecting skin capillary perfusion, which may include cardiovascular disorders, dermatologic disorders, skin wounds, ocular disorders, psychiatric disorders, and neurologic disorders. 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. 2020-07-01 PURPOSE: To report blood flow in the optic nerve head between the right and left eyes or the superior and inferior neuroretinal rims in normal volunteers using laser speckle flowgraphy. METHODS: This prospective study included 120 eyes of 60 normal volunteers (mean age, 50.0 +/- … 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 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.

Ocular blood flow was evaluated with laser speckle flowgraphy, and the mean blur rate (MBR) at the optic nerve head was analyzed. Relationships between right-left differences in mean deviation (MD), intraocular pressure, MBR, spherical equivalent, central corneal thickness, and mean ocular perfusion pressure were evaluated using Spearman’s rank correlation coefficient.

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.
