[Evaluation of blood perfusion velocity in the ophthalmic artery of glaucoma patients].
One hundred and ten examination were performed in 71 patients with primary glaucoma aged 21-81 years (217 eyes). The blood perfusion speed in the ophthalmic artery was measured in each patient by the ultrasonographic pulsating Doppler's method with a probe of a 2.0 MHz frequency by means of a TC-2-64 apparatus of EME production. The ophthalmic artery was examined by transorbital technique according to Spencer and Whisler on a 40-50 mm depth. The examined orbits were divided into 4 groups in dependence of the grade of the optic nerve atrophy. A lowering of over 50 per cent of the blood speed (below 10 cm/s) was found in 10.6 per cent of the eyes. Optic atrophy of the 3d and 4th grade was revealed in 70 p.c. of these eyes; the intraocular pressure remained in normal limits.
