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...
متن کاملA novel, microscope based, non-invasive laser Doppler flowmeter for choroidal blood flow assessment.
Impaired ocular blood flow is involved in the pathogenesis of numerous ocular diseases like glaucoma or AMD. The purpose of the present study was to introduce and validate a novel, microscope based, non-invasive Laser Doppler Flowmeter (NI-LDF) for measurement of blood flow in the choroid. The custom made NI-LDF was compared with a commercial fiber optic based laser Doppler flowmeter (Perimed P...
متن کاملSound-induced artifact in cochlear blood flow measurements using the laser Doppler flowmeter.
The laser Doppler flowmeter has been shown to give a response from the cochlea during high intensity acoustic stimulation which is not related to blood flow through the cochlea. The magnitude of this response depends upon the intensity and frequency of stimulation and the location of the probe on the cochlea. Evidence is presented that the response is derived from the vibration of cochlear tiss...
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...
متن کاملTissue blood flow measurement by laser Doppler technique
Measurement of blood flow and the effects of different factors on tissue blood flow are important fields of research in physiology and pharmacology. So far, different methods have been innovated, using laser light is the Last one. In this article history, principles and specifications of laser technique along with its advantages and disadvantages ( in comparison with other methods) are revie...
