title: [Correlation of blood flow in the posterior ciliary arteries with visual field changes and the appearance of the optic disc in patients with primary glaucoma].
abstract: The velocity of blood perfusion and pulsation curve in posterior ciliary arteries was evaluated in 180 patients (476 eyes) with primary glaucoma, aged 22 to 81 years. The investigations were carried out by Doppler's focused pulsating ultrasonographic method with probes of 2 and 8 MHz frequency connected with a TC-2-64 apparatus (made by EME of German Federal Republic). The blood perfusion in the posterior ciliary arteries was compared with the changes in the visual field, in the aspect of the optic disc in patients with primary glaucoma and various levels of the IOP. In patients with primary glaucoma and advanced fundus changes (of 2-nd and 3-rd grade) the mechanisms of regulation of the ciliary circulation were normally functioning for quite a long time. In the period of breaking down of the mechanisms the changes in the visual field came into being.
