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 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.

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

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. 2017-07-24 · Laser speckle flowgraphy. Laser speckle flowgraphy (LSFG) is a non-invasive modality that enables measurement of ocular blood flow. The LSFG system uses a regular charge-coupled-device camera to capture a frame size of 750 x 360 pixels at a temporal frame rate of 30 frames per second.

NIDEK CO., LTD., a global leader in the design, manufacturing, and distribution of ophthalmic, optometric, and lens edging equipment, is pleased to announce the launch of the LSFG-RetFlow Laser Speckle Flowgraphy.

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.

Laser speckle flowgraphy (LSFG) is a noninvasive technique that can measure relative blood flow velocity in the optic fundus contributed by the ophthalmic artery, the main first branch originating from the internal carotid artery (ICA).

Reproducibility of Blood Flowmetry in Human Retina Using the Nidek Laser Speckle Flowgraphy LSFG-NAVI System (LSFG Repro) The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean … Underlying physical principles and devices available Some of these cookies are essential to the operation of the site, while others help to improve your experience by providing insights into how the … Laser speckle flowgraphy (LSFG) is an ophthalmologic equipment that qualitatively detects the blood flow of the optic nerve head, which is known to be related with cerebral microcirculation. 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.
