利用超声多普勒测定血流速度,现已广泛应用于全身各器官血管性疾病的诊断和血流动力学的研究。Yamamoto 等1979年首先把超声多普勒技术用于青光眼的血流动力学研究,此后有不少学者利用这一技术测定了视神经萎缩和青光眼患者的颈总、颈内动脉和眼动脉的血流速度,提出了青光眼患者视功能减退是由于颈动脉狭窄而致营养障碍所造成的新观点。为探讨青光眼患者的视功能损害和颈总、颈内动脉的血流速度及血 The use of ultrasound Doppler blood flow velocity, has been widely used in the diagnosis of systemic vascular disease and hemodynamic studies. Yamamoto et al. First used Doppler ultrasound in the hemodynamic study of glaucoma in 1979. Since then, many scholars have used this technique to determine the blood flow of the cervical total, internal carotid and ophthalmic arteries in patients with optic atrophy and glaucoma Speed, put forward the glaucoma patients with visual impairment due to carotid stenosis caused by nutritional disorders caused by new ideas. To investigate the visual impairment in patients with glaucoma and total neck, internal carotid artery blood flow velocity and blood
