Abstract Objective: To explore ophthalmic vascular hemodynamic changes with color Doppler ultrasound in patients with cataract. Methods: 60 patients with cataract were divided into 2 groups, 30 cases with simple cataract(group Ⅰ) and 30 cases with cataract mergeing diabetes mellitus and/or hypertension(group Ⅱ). 30 cases of healthy volunteers was as the control group(group Ⅲ). Detected in ophthalmic artery(OA) and posterior ciliary artery(PCA) and central retinal artery(CRA) systolic blood flow velocity(Vs), end-diastolic blood flow velocity(Vd) and resistance index(RI). Results: The systolic blood flow velocity (Vs) and end-diastolic blood flow velocity(Vd) of OA, PCA, CRA of group Ⅱ were significantly lower, vascular RI were significantly increased, the condition of low velocity and high resistance of blood flow spectrum. There was statistically significant difference compared with group Ⅲ(all P<0.05). Vs, Vd and vascular RI of OA, PCA, CRA of group Ⅰ were no obvious changes of blood flow spectrum. There was no statistically significant difference compared with group Ⅲ(all P>0.05). Conclusions: Eye vascular hemodynamics change associated with diabetes and hypertension, not cataracts. Application of color Doppler ultrasound can accurately reflect the changes of ocular vascular hemodynamics in patients with cataract and provides an important reference for clinical value.
