Abstract:
Objective To investigate the retrobulbar hemodynamic changes in elderly patients with ischemic ophthalmopathy(IOP).Methods Three groups of 35 elderly unilateral IOP(n=35 patients),32 elderly normal eye(n=32 volunteers)and 30 non-elderly normal eye(n=30 volunteers) were recruited in our hospital for the IOP or not,for elderly(aged≥60)or not(aged ＜60).The peak systolic velocity(PSV),end-diastolic velocity(EDV),resistance index(RI),color Doppler blood stream spectrum form and arm-retinal circulation time(A-RCT) in both ophthalmic artery(OA) and central retinal artery(CRA)were measured on three groups by color Doppler flow imaging(CDFI)and fundus fluorescein angiography(FFA).Results Compared with elderly normal eye group,or with non-elderly normal eye group,the elderly unilateral IOP group showed that PSV and EDV of both OA and CRA were decreased,RI was increased,CD blood stream spectrum form was changed and A-RCT was prolonged(all P＜0.05).Compared the non-elderly normal eye group,the elderly normal eye group showed that the difference in PSV,EDV,RI,A-RCT had no statistical significance(all P ＞0.05),while CD blood stream spectrum form was changed(P＜0.05).Conclusions In the elderly unilateral IOP patients,PSV and EDV of both OA and CRA are decreased,RI is increased,blood stream spectrum form is changed,and A-RCT is prolonged.The color Doppler uhrasound-detected hemodynamic changes are displayed clearly so that CDFI can provide a reliable evidence for clinical diagnosis of IOP.
