Point-of-care ultrasound has become an integral part of the evaluation of monocular vision loss. Most commonly, it has been used to evaluate retinal detachment, vitreous hemorrhage, and posterior vitreous detachment. Point-of-care ultrasound can also be used to evaluate central retinal arterial occlusion, whereby a retrobulbar spot sign is present. We present a case series of 4 patients presenting with monocular vision loss who were found to have central retinal artery occlusion. We describe what a retrobulbar spot sign is and how its presence or absence can assist in the evaluation and treatment of these patients.
床边超声已成为单眼视力丧失评估的重要组成部分。它最常用于评估视网膜脱离、玻璃体积血和玻璃体后脱离。床边超声还可用于评估视网膜中央动脉阻塞，此时会出现球后斑点征。我们介绍了 4 例以单眼视力丧失为表现的患者病例系列，这些患者均被诊断为视网膜中央动脉阻塞。我们描述了球后斑点征是什么，以及其存在或缺失如何帮助评估和治疗这些患者。
