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 50% of CRAOs and one in 4 with BRAOs have the spot sign and would not benefit from systemic thrombolysis.
