We aimed to assess the proportion of cardiac patients with retinal emboli before coronary catheterization and the proportion with newly developed retinal embolism shortly after coronary catheterization 我们的研究目的是评估心脏病患者在冠状动脉导管插入术前视网膜动脉栓塞的比例，以及在冠状动脉导管插入术后短期内新发生视网膜动脉栓塞的比例。

Conclusions ? asymptomatic retinal emboli are relatively common in patients being assessed for coronary artery disease . we found no evidence suggesting coronary catheterization contributes to retinal embolism shortly after the procedure 结论? ?无症状的视网膜动脉栓塞在明确冠心病的患者中相对常见，我们没有发现冠状动脉导管插入术与术后短期内视网膜动脉栓塞有关的证据。
