[Evaluation of methods for reproducing doppler pulsating focused ultrasonography]

In 53 patients treated for primary glaucoma the authors performed 2 examinations of blood perfusion in the posterior ciliary arteries during 2 following days. The patients had been examined in the period of a normalized IOP. The difference in the IOP between the first and second examination did not exceed 3.3 mm Hg and the difference in the mean general blood pressure--10 mm Hg. The blood perfusion in the posterior ciliary arteries was checked by Doppler's pulsating focused ultrasonography, by means of a TC-2-64 apparatus with a probe of 8.0 MHz frequency. The velocity of the blood perfusion, the pulsating index and the transmission of pulsation were evaluated. The differences between respective parameters characterizing the blood perfusion in the posterior ciliary arteries between the first and second examination were statistically insignificant, on the importance level of 0.01.
