Application of color Doppler ultrasonography in treating ischemic optic neuropathy with extraocular counterpulsation
彩色多普勒超声在球外反搏治疗缺血性视神经病变中的应用

Objective To evaluate the influence of extraocular counterpulsation on ocular fundus blood vessels using high-frequency color Doppler ultrasonography.Methods Twenty-one patients with ischemic optic neuropathy were treated with extraocular counterpulsation.During treatment,the Doppler spectra were detected with high-frequency color Doppler ultrasonography.The peak systolic velocity(PSV),end diastolic velocity(EDV)and resistance retinal index(RI)of central retinal artery and posterior ciliary artery were meas...
