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).

It is also capable of analyzing the pattern of change of  22 May 2018 Nidek has announced the launch of the LSFG-RetFlow Laser Speckle Flowgraphy for noninvasive, real-time imaging and measurement of  19 Dec 2019 model predictions in a healthy population using Laser Speckle Flowg resistance and blood flow by means of Laser Speckle Flowgraphy. Vascular and tissue area mean blur rate (MBRV and MBRT), measured using laser speckle flowgraphy (LSFG), was significantly lower in the 32 included ODD   Laser speckle flowgraphy enables the in vivo quantification of circulation in the optic nerve head (ONH), choroid, and retinal vessels and can reveal the circulatory  12 Nov 2018 Laser speckle flowgraphy is a new method that enables the rapid evaluation of foot blood flow without contact with the skin.

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.
