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.

Its spatial resolution is determined by the laser wavelength, the quality of the optics, the optical properties of the tissue, and the amount of pixel averaging to estimate the speckle contrast.

LSFG has allowed us to measure the real time changes of retinal blood flow without pupillary dilatations and contrast media. In the present study, we investigated a novel technique to measure CBF based on laser speckle flowgraphy (LSFG) in healthy subjects. Methods: This study included 31 eyes of 31 healthy, non-smoking subjects aged between 19 and 74 years. A commercial LSFG instrument was used to measure choroidal vessel diameter (CVD) and relative flow volume (RFV 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. Thoracoscopic ganglionectomy with laser speckle flowgraphy effectively treats compensatory sweating.

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 ].

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.

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 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. There was total resolution of compensatory sweating and the patient's were "very satisfied" with the results. Laser speckle flowmetry can measure CBF changes two-dimensionally in real-time over a large area of cortex.

We report our results of ganglionectomy for facial blushing as a redo surgery. Abstract Laser speckle flowmetry (LSF) is useful to assess noninvasively two-dimensional cerebral blood flow (CBF) with high temporal and spatial resolution.

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.
