Abstract

Introduction

The ocular ultrasound spot sign negatively predicts the success of thrombolytic treatment in retinal arterial occlusions. We evaluated the presence of the spot sign in these patients.

Material and methods

Retrospective study of patients with acute central retinal artery occlusion (CRAO) or its branches (BRAO). An ocular ultrasound was performed to assess the presence of spot sign.

Results

Twenty patients were included, 13 CRAO and 7 BRAO. Carotid stenosis was the most common etiology, in 50%, 7 CRAO and 3 BRAO. A spot sign was observed in 9 patients (45%), 7 CRAO and 2 BRAO. We did not observe significant differences between patients with CRAO and BRAO. Patients with the spot sign were significantly older, 73 (± 9) vs 66 (± 6) years (p = 0.028).

Conclusions

Ocular ultrasound is very useful in the evaluation of patients with acute retinal ischemia. More than fifty percent of CRAOs and one in four with BRAOs have the spot sign and would not benefit from systemic thrombolysis.

眼超声监测急性视网膜动脉缺血的应用

眼部超声斑点征象负向预测溶栓治疗视网膜动脉闭塞的成功。我们评估了这些患者是否存在斑点征象。材料与方法对急性视网膜中央动脉闭塞（CRAO）或其分支（BRAO）患者进行回顾性研究。进行眼部超声检查以评估斑点征象的存在。结果共纳入20例患者，其中CRAO 13例，BRAO 7例。颈动脉狭窄是最常见的病因，占50%，7 CRAO和3 BRAO。斑点征9例（45%），cro 7例，BRAO 2例。我们没有观察到CRAO和BRAO患者之间的显著差异。有斑点征的患者年龄明显增大，分别为73（±9）岁和66（±6）岁（p = 0.028）。结论超声对急性视网膜缺血的诊断具有重要意义。超过50%的crao患者和四分之一的brao患者有斑点征象，不能从全身溶栓中获益。
