title: [Comparative evaluation of blood flow in posterior ciliary arteries in patients with glaucoma after surgical and pharmacological treatment].
abstract: The perfusion of blood and pulsation curve in the posterior ciliary arteries in glaucomatous patients was evaluated before and after surgical and pharmacological treatment by Doppler's focused pulsating ultrasonographic method by means of a TC-2-64 apparatus with a probe of 8 MHz frequency. Twenty two patients were treated only conservatively, 27 by a surgical intervention. Before the installation of the treatment the intraocular pressure was higher than 35 mm Hg (averagely), the perfusion velocity was lowered and the indexes of pulsation elevated. After surgery the IOP was lowered--averagely beneath 15 mm Hg, the velocity of blood perfusion and pulsation indexes showed normal values in all the operated persons. After pharmacological treatment the IOP lowered but its mean value persisted in the 20-22 mm Hg range. Only in patients with early glaucomatous changes the blood perfusion remained normal with the intraocular pressure around 20 mm Hg. Instead in patients with advanced glaucomatous changes the velocity of the blood perfusion and the pulsation indexes showed pathological values with the IOP around 20 mm Hg.
