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). 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.

Despite use of an ordinary CCD camera as the detector, the performance of laser speckle flowgraphy system for the analysis of ocular blood circulation is greatly improved to achieve higher resolution and a wider field of view for blood flow mapping.

Introduction. Laser speckle flowgraphy (LSFG) uses the laser speckle phenomenon in estimating ocular circulation in living eyes in a noninvasive manner.1 The current LSFG instrument yields the mean blur rate (MBR), which is a quantitative index of blood flow velocity in target tissues.

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 device used to measure the blood flow velocity is laser speckle flowgraphy ( LSFG), which is based on the movement of red blood cells; the device evaluates   It is suitable for comparing blood flow value variations before and after treatment, medication or operation.

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).

Using LSFG, a difference in skin blood flow between the 2 methods was detected.
