Shiba T(1), Takahashi M(2), Matsumoto T(1), Hori Y(1). Author information: (1)Department of Ophthalmology, Toho University Omori Medical Center, Tokyo, Japan. However, 10% to 15% of patients do not benefit from this intervention.

It was developed to facilitate the non-contact analysis of ocular blood flow in living eyes, utilizing the laser speckle phenomenon. 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). Here, we used laser speckle flowgraphy (LSFG), a non‐invasive technology that measures mean blur rate (MBR) and a number of derived parameters, to evaluate the hemodynamics of eyes with unilateral macula‐off RRD. We then determined the relationship between visual recovery and tissue blood flow in the optic nerve head (ONH). Laser speckle flowgraphy (LSFG) is a safe and quantitative devise for evaluating of ocular circulation [16, 17]. This is based on a change in patterns of the speckles of the laser light reflected from a retina and choroid [18, 19]. 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. LSFG can also measure the mean blur rate, which quantitatively calculates the blood flow.

The penetration depth of the laser is approxi- Laser speckle flowgraphy (LSFG) can be used to noninvasively measure ocular blood flow [1–4]. One indicator of ocular blood flow is the mean blur rate (MBR) [ 5 ].

Laser speckle flowgraphy (LSFG) allows for the quantitative estimation of blood flow in the optic nerve head, choroid, retina and iris in vivo. It was developed to facilitate the non-contact analysis of ocular blood flow in living eyes, utilizing the laser speckle phenomenon.

LSFG is used for research on various diseases in adult patients, such as glaucoma [ 5 , 6 ], retinal vein occlusion [ 7 ], and diabetic retinopathy [ 8 ]. Objectives: Laser speckle flowgraphy is a new method that enables the rapid evaluation of foot blood flow without contact with the skin. We used laser speckle flowgraphy to evaluate foot blood flow in peripheral arterial disease patients before and after surgical revascularization. Materials and methods: A prospective single-center study.

The treatment of compensatory sweating on the back, chest, and stomach The surgeon, Dr. Yamamoto, used laser speckle flowgraphy to determine from which level of the sympathetic chain the compensatory sweating signals were originating in 8 patients. The culprit ganglion levels were then removed.

Background. Despite success of thoracic sympathectomy (ETS), there are patients that develop postoperatively intensive sweating of the trunk. The aim of the study was to present outcomes of three of those methods: removal of the clips, clipping of T6-9, and regional abdomino-lumbar iontophoresis (RALI).

Laser speckle flowmetry (LSF) has been used to measure blood flow in skin, and retina, among many other tissues (Briers, 2001; Ruth, 1990; Yaoeda et al., 2000). LSF provides full-field analysis of time-varying speckle contrast fluctuations, and therefore, real-time two-dimensional CBF imaging, a clear advantage over laser-Doppler scanning techniques.

The aim of the study was to present outcomes of three of those methods: removal of the clips, clipping of T6-9, and regional abdomino-lumbar iontophoresis (RALI). Methods. Out of the group of 229 patients treated with ETS, there were 9 that Laser speckle flowgraphy (LSFG) is a noninvasive method for quantitative evaluation of blood flow using the mean blur rate (MBR) as the blood flow index. We investigated whether LSFG can intraoperatively detect the demarcation line after vessel dissection and reduce the incidence of anastomotic leakage (AL). Laser speckle flowgraphy (LSFG) allows for the quantitative estimation of blood flow in the optic nerve head, choroid, retina and iris in vivo. It was developed to facilitate the non‐contact analysis of ocular blood flow in living eyes, utilizing the laser speckle phenomenon. 2020-02-07 · 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).

Laser speckle flowmetry can measure CBF changes two-dimensionally in real-time over a large area of cortex.

The speckle pattern appears in accordance with blood flow velocity.1,2 Herein, we applied LSFG techniques to treat compensatory sweating (CS) (Video 1). With laser speckle flowgraphy, the sympathetic nerve related to the sweating of various parts of the body could be identified. 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. Recurrence and compensatory sweating (CS) after endoscopic thoracic sympathectomy (ETS) are considered difficult to treat. However, the part of the sympathetic nerves causing the CS can be used intraoperative laser speckle flowgraphy (LSFG) to perform precise thoracoscopic ganglionectomies. LSFG allows the monitoring of transient changes in skin blood perfusion in response to electrical stimulation of a dermatome's corresponding sympathetic nerve and ganglion.
