title: [Blood flow in ocular vessels in 2 types of ocular ischemic syndrome].
abstract: Ultrasonic triplex scanning of the orbit (gray scale two-dimensional ultrasonic examination, color Doppler mapping (CDM), and dopplerography) was carried out in 148 patients with ocular ischemic syndrome (OIS) aged 35-70 years, 104 of these with acute and 44 with primary chronic course. Signs of disordered bloodflow in the orbital and central retinal arteries were detected in patients with acute disease: 2-fold decreased maximum systolic bloodflow velocity, 5-fold decreased end diastolic bloodflow velocity, and 1.5 times increased resistance index in comparison with the norm. Chronic course of OIS was characterized by decreased maximum systolic velocity (by 1.5 times) and end diastolic bloodflow velocity (3-fold) in comparison with the norm in both arteries. Studies of ocular bloodflow by CDM timely detected angiological disorders in OIS and help define (in cooperation with angiosurgeon) the indications for angioreconstructive operations.
