Purpose: Laser speckle flowgraphy (LSFG), a new, non-invasive method of measuring the mean blur rate (MBR) of ocular blood flow, allows for the analysis of the pulse waveform of a heartbeat as it changes dynamically. Here, we investigated the relationship between the pulse waveform and clinical parameters, particularly age.

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 FLOWGRAPHY LSFG-RetFlow: Related Products. Ophthalmology & Optometry.

With laser speckle flowgraphy, the sympathetic nerve related to the sweating of various parts of the body could be identified. The treatment of compensatory sweating on the back, chest, and stomach was previously considered to be difficult; however, compensatory sweating is demonstrated to be treatable with this technique.

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. In recent years, laser speckle flowgraphy (LSFG) has been introduced as a non-invasive, easy to perform, and reliable means of measuring retinal blood flow , , , . The principles of LSFG have been well described .

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.

Here, we investigated the relationship between the pulse waveform and clinical parameters, particularly age. It is difficult to identify glaucoma in myopic eyes because the configuration of the optic disc varies; yet it is important clinically. Here, we used laser speckle flowgraphy (LSFG) to measure mean blur rate (MBR), representing optic disc microcirculation, and assessed its ability to identify glaucoma in eyes with myopic optic discs.
