Doppler ultrasound was used to detect possible flow changes in the carotid arteries of patients with central retinal artery and vein occlusion. Twenty-three patients with central retinal artery occlusion (mean age 56, SD 11, years) were examined 4 to 48 months after the development of the occlusion and compared with age and sex matched control subjects with no history of any disease known to be associated with pathological changes in carotid vessels. Significant stenosis or occlusion of one or more carotid arteries was discovered in eight patients with retinal artery occlusion, while the ultrasonic findings were normal in all the controls (p less than 0.005). Blood flow was evaluated by the same method in 16 patients with central retinal vein occlusion (mean age 57, SD 9, years) six to 48 months after the event. A control group was chosen according to the same criteria as in previous comparison. Pathological ultrasonic findings were observed neither in the patients with retinal vein occlusion nor in the control group. The results suggested a possible aetiological relation between pathological changes in the carotid arteries and occlusion of the central retinal artery, but not occlusion of the central retinal vein.
采用多普勒超声检测视网膜中央动脉和静脉阻塞患者颈动脉可能存在的血流变化。对23例视网膜中央动脉阻塞患者（平均年龄56岁，标准差11岁）在阻塞发生后4至48个月进行检查，并与年龄和性别匹配、无任何已知与颈动脉血管病理改变相关疾病史的对照者进行比较。在8例视网膜动脉阻塞患者中发现一条或多条颈动脉存在明显狭窄或阻塞，而所有对照者的超声检查结果均正常（p<0.005）。对16例视网膜中央静脉阻塞患者（平均年龄57岁，标准差9岁）在事件发生后6至48个月采用相同方法评估血流情况。按照与先前比较相同的标准选择对照组。视网膜静脉阻塞患者和对照组均未观察到病理性超声检查结果。结果提示，颈动脉的病理改变与视网膜中央动脉阻塞之间可能存在病因学关系，但与视网膜中央静脉阻塞无关。
