Study of the ocular hemodynamics in patients with hypertension by color Doppler imaging

Objective:To understand the ocular hemodynamics in patients with hypertension.Methods:This study included142eyes of71patients with hypertension.The criteria of hemodynamics of the ocular artery(OA),central retinal artery(CRA)and short posterior ciliary artery(SPCA)were measured by color doppler image(CDI).The results of patients with hypertension were compared with those of the control group which included60eyes of30person without hypertension.Results:The ophthalmic bloodstream speed decreased and resistance index(RI)inˉcreased obviously,the ophthalmic blood vessels of hypertension was in a state of lowbloodstream and high resistance.Conclusion:The examination of ophthalmic vascular hemodynamics of hypertension with color Doppler ultrasound,which can accurately reflect the peripheral vascular resistance and the blood supply,is of great significance to the observation of curative effect and the assessment of prognosis.
