摘　　要：目的通过对眼动脉(ophthalmic artery,OA)及其终末支滑车上动脉(supratrochlear artery,STCA)的彩色多普勒超声检测,探讨2型糖尿病视网膜病变患者眼部的血流变化特征及其上述动脉间血流变化的关系。方法 52例糖尿病无视网膜病变组(non-diabetic retinopathy,NDR组)和60例糖尿病视网膜病变组(diabetic retinopathy,DR组)患者行OA和STCA彩色多普勒超声检测。测量二组患者OA和STCA的收缩期峰值速度(peak systolic velocity,PSV),舒张末期速度(end diastolic velocity,EDV)和阻力指数(resistive index,RI)值。采用非配对t检验比较二组患者间差异,采用线性回归方程分析OA与STCA的相关性。结果 DR组OA和STCA的PSV[OA:(25.52±4.72)cm/s vs(30.83±3.26)cm/s;STCA:(26.93±3.48)cm/s vs(30.28±3.87)cm/s]与EDV值[OA:(5.39±1.53)cm/s vs(8.41±1.20)cm/s;STCA:(6.19±1.31)cm/s vs(8.24±1.46)cm/s]均低于NDR组,RI值(OA:0.79±0.05vs 0.73±0.04;STCA:0.77±0.04 vs 0.72±0.05)高于NDR组,差异有统计学意义(P<0.01);DR组OA与STCA的血流参数均存在正相关(PSV:r=0.941,EDV:r=0.750,RI:r=0.592)。结论在2型糖尿病视网膜病变患者中,OA及STCA均可出现血流动力学异常,且STCA可间接反映OA的血流动力学变化,为糖尿病视网膜病变患者眼部血流变化的检查开辟了新的途径。Objective To analyze the characteristic changes of these arteries in Type 2 patients with diabetes retinopathy through detection of the ophthalmic artery （OA） and supratrochlear artery （STCA） by highresolution color Doppler. Methods One hundred and twelve patients were enrolled in this study and divided into two groups （ 52 patients with diabetes retinopathy DR and 60 patients without diabetes retinopathy NDR）. The peak systolic velocity （PSV）, end diastolic velocity （EDV） and resistive index （RI） of STCA and OA of all subjects were measured by ultra broadband probe （Philips IU- 22）, respectively. Results Both PSV （OA： 25.52± 4.72 cm/s vs. 30.83 ± 3.26 cm/; STCA： 26.93 ± 3.48 cm/s vs 30.28 ± 3.87 cm/ s ） and EDV （OA：5.39± 1.53 cm/s vs 8. 41 ±1.20 cm/s; STCA：6.19± 1.31 cm/s vs 8. 24± 1.46 cm/s ） of OA and STCA were significantly decreased in DR than that in NDR, （P〈0. 001）. And the RI （OA： 0.79± 0.05VS0.73 ± 0.04; STCA：0.77 ± 0.04 vs 0.72 ± 0.05 ） of OA and STCA was increased in DR than that in NDR （P〈0. 001）. The positive correlation was found between STCA and OA （PSV： r = 0. 941,EDV.. r = 0. 750,RI： r = 0. 592） in DR. Conclusion The homodynamic changes of OA is indirectly reflected by the STCA in DR patients.
