For developing a commercial version of LSFG, the special area sensor was replaced by the ordinary charge-coupled device camera. PURPOSE: To assess the feasibility and reliability of Laser Speckle Flowgraphy (LSFG) to measure ocular perfusion in a sample of healthy white subjects and to elucidate the age-dependence of the parameters obtained. Laser speckle flowgraphy‐ and optical coherence tomography angiography‐derived variables at different stages of glaucoma. Laser speckle flowgraphy is a valuable way of evaluating the time course of changes in ocular blood flow caused by ischemic retinal diseases such as DR or RVO. In particular, LSFG can compare circulation before and after pharmacological intervention. PURPOSE: To assess the feasibility and reliability of Laser Speckle Flowgraphy (LSFG) to measure ocular perfusion in a sample of healthy white subjects and to elucidate the age-dependence of the parameters obtained. 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).

Compared to other laser-based techniques (i.e., laser Doppler velocimetry and flowmetry), the LSFG measurement 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. 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 2020-06-23 · Using laser speckle flowgraphy, investigators aimed to determine the relationship between blood flow in retinal vessels and capillaries, blood flow in cervical arties, and the development of retinopathy in patients with type 2 diabetes.

Purpose: Innovative laser speckle flowgraphy (LSFG) enables noninvasive evaluation of retinal microcirculation and the usefulness has been reported in the field of ophthalmology. LSFG has allowed us to measure the real time changes of retinal blood flow without pupillary dilatations and contrast media. Laser speckle flowgraphy (LSFG) allows for the quantitative estimation of blood flow in the optic 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. For developing a commercial version of LSFG, the special area sensor was replaced by the ordinary charge-coupled device camera.

Laser Speckle Flowgraphy LSFG-Retflow Zur retinalen und choroidalen Perfusionsanalyse . Das nicht-invasive LSFG-RetFlow bietet eine farbcodierte Visualisierung und quantitative Auswertung verschiedener Indizes zur Perfusionsgeschwindigkeit der retinalen und choroidalen Blutgefäße. A new technique is developed to visualize the blood flow map of the human retina using laser speckle phenomena. 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. 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.
