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. 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 .

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. 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. 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. 129 eyes (normal disc: 21 eyes; myopic disc: 108 eyes) were Correlation between laser speckle flowgraphy and optical coherence tomography angiography measurements in normal and glaucomatous eyes Javascript is currently disabled in your browser.

Refraction (20) Diagnostic (23) Surgical & IOL (11) Ophthalmic Laser (4) Other Laser speckle flowgraphy (LSFG) allows for the quantitative estimation of blood flow in the optic nerve head (ONH), choroid and retina in vivo, utilizing the laser speckle phenomenon. 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.

Reproducibility of retinal circulation measurements obtained using laser speckle flowgraphy-NAVI in patients with glaucoma. Clin Ophthalmol. 2011;5:1171–1176. 13. Luft N, Wozniak PA, Aschinger GC, et al.

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. 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 (LSFG) utilizes the laser speckle phenomenon for the measurement of ocular blood flow in a noninvasive manner . LSFG provides the mean blur rate (MBR), which is proportional to blood velocity and has been used for the measurement of relative differences in blood flow in the optic nerve head (ONH) [ 18 – 20 ].
