Abstract:
Objective To explore the feasible of diagnosing ischemic cerebrovascular diseases by detecting central retina artery sclerosis(CRA) with color Doppler ultrasonography.Methods210 patients with ischemic cerebrovascular disease(420 eyes) and 80 healthy volunteers(160 eyes) were examined by color Doppler flow imaging(CDFI) to detect double sides blood frequency spectrum of CRA and hemodynamic parameters of CRA including peak systolic velocity(PSV),end of diastolic velocity(EDV)and resistant index(RI).ResultsThe blood frequency spectrum of CRA showed three apices and two vales or slanting triangle in healthy volunteers.But in patients with ischemic cerebrovascular disease,the blood frequency spectrum changed,and PSV and EDV were slower and RI increased compared with those in the healthy volunteers(PP<0.05～0.001).ConclusionIn patients with ischemic cerebrovascular disease,the blood flow of CRA is slower and RI increases compared with health individuals.The color Doppler ultrasonography can used for diagnosis of CRA sclerosis.
