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 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

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. 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.

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.

Introduction Arterial supply to the orbit is complex and makes various

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.

Laser speckle flowmetry The technique for LSF has been described in detail else-where (Dunn et al., 2001). Briefly, a CCD camera (Cohu, San Diego, CA, U.S.A.) was positioned above the head, and a laser diode (780 nm) was used to illuminate the skull surface in a diffuse manner. The penetration depth of the laser …

Methods . Twenty-eight eyes of 28 patients with NTG and 25 eyes of 25 normal subjects matched for age, refractive errors, systemic blood pressure, and central corneal thickness were evaluated. Laser Speckle Contrast Imager #moorFLPI-2. Full-field, video frame rate blood flow imaging. In a nutshell, moorFLPI-2 is the most user-friendly system for studying cerebral blood flow regulation in rodents.

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.
