Free Flap Blood Flow Evaluated Using Two-Dimensional Laser Speckle Flowgraphy
Objective. We investigated the efficiency of laser speckle flowgraphy for evaluating blood flow in free flaps used for plastic surgery. Methods. We measured blood flow using a visual laser meter capable of providing two-dimensional color graphic representations of flow distribution for a given area using a dynamic laser speckle effect. Using laser speckle flowgraphy, we examined the blood flow ...
متن کاملOcular Blood Flow Measurements in Healthy White Subjects Using Laser Speckle Flowgraphy
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. METHODS This cross-sectional study included 80 eyes of 80 healthy, non-smoking white subjects of Western European descent between 19 and 79 years of age. A commercial LSFG instrume...
متن کاملChoroidal blood flow impairment demonstrated using laser speckle flowgraphy in a case of commotio retinae
Purpose To report the time course of choroidal blood flow (CBF) in a commotio retinae case using laser speckle flowgraphy (LSFG). Observations A 58-year-old Japanese man with complaints of worsening left visual acuity after blunt eye trauma was diagnosed with commotio retinae. A funduscopic examination showed macular opacity, and LSFG results demonstrated CBF impairment in the affected eye.Op...
متن کاملLongitudinal changes of ocular blood flow using laser speckle flowgraphy during normal pregnancy
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. Herein, we investigated the change of retinal blood flow in normal pregnant women during gesta...
متن کاملEffects of water drinking test on ocular blood flow waveform parameters: A laser speckle flowgraphy study
The water-drinking test (WDT) is a provocative test used in glaucoma research to assess the effects of elevated intraocular pressure (IOP). Defective autoregulation due to changes in perfusion pressure may play a role in the pathophysiology of several ocular diseases. This study aims to examine the effects of WDT on ocular blood flow (in the form of pulse waveform parameters obtained using lase...
