[Evaluation of circulatory flow in vessels of the eye and orbit using color duplex ultrasonography].

Duplex ultrasonography is recent imaging, that allows simultaneous 2-dimensional imaging (B-scan) and Doppler evaluation of the blood flow. Information on blood flow is obtained by pulsed Doppler spectral analysis. The blood flow in vessels of our interest is colour coded. Using this technique we examined 140 eyes. 81 eyes in 48 healthy persons were examined. Based on this examinations, the blood velocity standards were calculated for age groups 19-40 and 41-76 y. There are demonstrated pathologic findings by intraocular tumor, tractional retinal detachment and various failures of blood flow in bulbar and orbital vessels.
