    IntroductionThe 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 MethodsRetrospective 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.ResultsTwenty 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).ConclusionsOcular 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.Copyright © 2024 Elsevier España, S.L.U. All rights reserved.
