It's been suspected considering greater than a century that disturbed ocular blood move (OBF) may well play a job within the pathogenesis of glaucoma. lowered OBF has been measured in glaucoma sufferers by means of numberless centres with diverse suggestions in numerous tissues of the attention. And decreased OBF has been confirmed to be of prognostic price. however the implementation of this information into medical perform has been very sluggish. This sensible publication may help many ophthalmologists to raised comprehend glaucoma. The interpreting of this e-book won't in simple terms enhance sufferer care but additionally supply the reader highbrow delight.

Sample text

Blood flow velocity in a selected vessel (bottom). 22 • Ocular Blood Flow and Glaucomatous optic neuropathy A color Doppler is a device that combines imaging with a B-scan, localization of blood flow based on a Doppler principle, and quantification of blood flow velocity with pulsed Doppler technique. This is the technique used most often today for patients with glaucoma. 22). These techniques, however, will not be discussed any further here as, at present, there is limited information concerning the relationship between OPA and OBF.

B, the retinal vessel diameter of a vascular section using the retinal vessel analyzer. Constriction resulted after the patient breathed in 100% oxygen. 19 Principle of the Doppler effect. A laser beam reflected by a moving object returns with a frequency change, ∆ f, known as Doppler shift. The velocity, v, can be determined from ∆ f. 20). Based on these two variables, a third variable, the so-called “flux” can be calculated. Unlike velocimetry, flowmetry measures the blood flow in capillary beds.
