A retrospective study covering 151 patients was conducted in order to determine the incidence of risk factors (arterial hypertension, diabetes mellitus, smoking, hyperlipidemia, and cardiovascular disorders) in cases of retinal artery occlusion. Occlusion of the central artery was found in 43% of the patients, occlusion of one or several branch arteries in 53%, and cilioretinal artery occlusion in 4%. A monofactorial study of risk factors produced a statistically significant value only for arterial hypertension (P = 0.01). Smoking and diabetic metabolism were not significant, and the correlation with hyperlipidemia was weak (P = 0.08). Forty-six patients were examined by continuouswave Doppler sonography: stenosis of the internal carotid artery was found in 50% of these cases. Pathologic Doppler findings were associated with an embolus in 14 cases (57%) and central artery occlusion in 9 (40%). Since retinal artery occlusion is frequently associated with carotid artery disease, systematic Doppler examination of the carotid vessels and the cardiovascular system should be performed in all patients with retinal artery occlusion.
为了确定视网膜动脉阻塞病例中危险因素（动脉高血压、糖尿病、吸烟、高脂血症和心血管疾病）的发生率，对151例患者进行了一项回顾性研究。发现43%的患者为中央动脉阻塞，53%的患者为一条或多条分支动脉阻塞，4%的患者为睫状视网膜动脉阻塞。对危险因素进行单因素研究时，仅动脉高血压具有统计学意义（P = 0.01）。吸烟和糖尿病代谢无统计学意义，与高脂血症的相关性较弱（P = 0.08）。对46例患者进行了连续波多普勒超声检查：其中50%的病例发现颈内动脉狭窄。病理多普勒检查结果显示，14例（57%）与栓子有关，9例（40%）与中央动脉阻塞有关。由于视网膜动脉阻塞常与颈动脉疾病相关，因此应对所有视网膜动脉阻塞患者进行颈动脉和心血管系统的系统性多普勒检查。
