Ocular 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 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...
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 کاملOcular blood flow before, during, and after vitrectomy determined by laser speckle flowgraphy.
BACKGROUND AND OBJECTIVE Vitrectomy markedly alters the intraocular milieu, which can then affect the physiology of the retina and choroid. This study investigates whether vitrectomy also alters ocular blood flow as determined by laser speckle flowgraphy (LSFG). PATIENTS AND METHODS Twenty eyes of 20 patients that underwent vitrectomy for idiopathic macular hole or epiretinal membrane were st...
متن کاملReproducibility of Neonate Ocular Circulation Measurements Using Laser Speckle Flowgraphy
Measuring the ocular blood flow in neonates may clarify the relationships between eye diseases and ocular circulation abnormalities. However, no method for noninvasively measuring ocular circulation in neonates is established. We used laser speckle flowgraphy (LSFG) modified for neonates to measure their ocular circulation and investigated whether this method is reproducible. During their norma...
