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).

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. The LSFG-RetFlow is an innovative product for non-invasive, real-time imaging and measurement of ocular blood flow that will aid in the clinical evaluation of glaucoma and retinochoroidal vascular disease.

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.

This study was designed to investigate the association between ocular blood flow measured using laser speckle flowgraphy (LSFG) and radial arterial pressure

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). 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. The LSFG-RetFlow is an innovative product for non-invasive, real-time imaging and measurement of ocular blood flow that will aid in the clinical evaluation of glaucoma and retinochoroidal vascular disease.

Laser speckle flowgraphy (LSFG), which uses the laser speckle phenomenon to detect and quantify the motion of blood cells in the ocular fundus, is one of the most promising candidates in this search. 5–23 Moreover, a recently developed measurement parameter derived from LSFG, the mean blur rate (MBR), can serve clinically as a quantitative and reproducible index of retinal blood cell 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. 2004-07-01 2018-11-12 laser speckle flowgraphy. Hideki Chuman*, Takako Hidaka, Nobuhisa Nao-i Department of Ophthalmology, Faculty of Medicine, University of Miyazaki, Japan Accepted on October 16, 2017 Keywords: Laser speckle flowgraphy, orbital tumors, optic disc blood flow. 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.

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.
