Scanning laser Doppler flowmeter study of retinal blood flow in macular area of healthy volunteers.
AIM To compare the interocular and intraocular differences of capillary perfusion, and the intraocular regional differences of retinal blood flow in the macular area of healthy volunteers. METHODS Tissue blood flow in the macula was examined in both eyes of 20 healthy volunteers with the Heidelberg retinal flowmeter. Blood flow measurements were made in a 10 degrees x 2.5 degrees area superio...

Aim: To compare the interocular and intraocular differences of capillary perfusion, and the intraocular regional differences of retinal blood flow in the macular area of healthy volunteers. Methods: Tissue blood flow in the macula was examined in both eyes of 20 healthy volunteers with the Heidelberg retinal flowmeter. Blood flow measurements were made in a 10 6̊2.5 ̊ area superior and inferior t...
متن کاملInability of a Confocal Scanning Laser Doppler Flowmeter to Measure Choroidal Blood Flow in the Pig Eye
The aim of the study was to determine whether the Heidelberg Retinal Flowmeter (HRF), a confocal scanning laser Doppler flowmeter, can measure choroidal blood flow in pig eyes.An HRF was used to obtain flow maps from in vitro pig eyes under a range of perfusion flow rates (0 - 500 microL/min) under conditions in which only the choroid was perfused. In some cases choroidal blood flow was also me...
متن کاملScanning laser Doppler flowmetry shows reduced retinal capillary blood flow in CADASIL.
BACKGROUND AND PURPOSE Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is a progressive systemic nonatherosclerotic angiopathy which causes ischemic strokes and vascular subcortical dementia. A cross-sectional study was performed to examine the retinal vascular caliber and blood flow in CADASIL. METHODS Scanning laser Doppler flowmetry was ...
متن کاملEvaluation of a laser Doppler flowmeter to assess blood flow in human primary incisor teeth.
PURPOSE This study determined whether the portable Advance Laser Flowmeter Model 21, a clinical instrument, would indicate significant values when pulpal blood flow was present or absent; whether the analog output of the flowmeter was time-linked to the heart rate; and whether labial and lingual crown surfaces produced different flow values. METHODS Teeth were tested under two conditions: wit...
