It was developed to facilitate the non‐contact analysis of ocular blood flow in living eyes, utilizing the laser speckle phenomenon. PURPOSE: Innovative laser speckle flowgraphy (LSFG) enables noninvasive evaluation of retinal microcirculation and the usefulness has been reported in the field of ophthalmology. LSFG has allowed us to measure the real time changes of retinal blood flow without pupillary dilatations and contrast media. Laser speckle flowgraphy (LSFG) is a technique that quantifies blood flow based on speckle statistics. 18 This technique has been used to study optic nerve head blood flow, 19 20 but when retinal areas are measured the signal contains proportions from both retinal and choroidal circulations.

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). 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).
Background. Despite success of thoracic sympathectomy (ETS), there are patients that develop postoperatively intensive sweating of the trunk.
The laser speckle phenomenon is an interference event observed when coherent light sources, such as lasers, are scattered by a diffusing surface. 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.
A new method is demonstrated to visualise the microcirculation map of the human retina using a dynamic laser speckle effect.
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

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). The aim of this study was to assess the feasibility of ocular b …
Recently, ganglionectomy using application of laser speckle flow graph has been evaluated for the treatment of compensatory sweating.

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. 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].

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.

METHODS: We retrospectively studied 82 eyes of 82 open-angle glaucoma (OAG) patients who underwent same-day LSFG and OCTA examinations, with 20 eyes of 20 healthy subjects The body still needs to sweat to thermoregulate. Also, the use of laser speckle flowgraphy doesn't make sense. It checks the vasodilation of blood vessels.
