Central Retinal Artery Occlusion is a cause of vision loss that warrants emergent evaluation. Ocular Point of Care Ultrasound (POCUS) is a non-invasive, inexpensive, and rapid modality to establish diagnosis with reduced time to consultation and treatment. This was a retrospective case series of patients evaluated at seven hospitals with diagnosis of CRAO over a two-year period. All patients underwent ocular POCUS performed by an emergency medicine clinician. Nine patients were evaluated with mean vision loss of 21 hours. Overall, 88% of patients were diagnosed with CRAO, 75% possessing US confirmed retrobulbar spot sign (RBBS), and 38% confirmed diagnosis with fundoscopy. Ocular POCUS is an examination all emergency medicine clinicians should be able to perform. A rapid diagnosis of CRAO provides opportunity for vision improvement with initiation of treatment. The lack of guidelines for treatment of CRAO represents an opportunity for a multi-speciality collaboration to develop a diagnostic and treatment algorithm.
视网膜中央动脉阻塞是导致视力丧失的一个原因，需要进行紧急评估。眼部即时超声检查（POCUS）是一种非侵入性、低成本且快速的检查方式，能够在减少会诊和治疗时间的情况下做出诊断。这是一项回顾性病例系列研究，研究对象为在两年时间里于七家医院接受评估并诊断为视网膜中央动脉阻塞的患者。所有患者均接受了由急诊医学临床医生进行的眼部即时超声检查。九名患者接受了评估，平均视力丧失时间为21小时。总体而言，88%的患者被诊断为视网膜中央动脉阻塞，75%的患者经超声检查确认存在球后斑点征（RBBS），38%的患者经眼底镜检查确诊。眼部即时超声检查是所有急诊医学临床医生都应能够进行的一项检查。对视网膜中央动脉阻塞的快速诊断为通过启动治疗来改善视力提供了机会。缺乏视网膜中央动脉阻塞的治疗指南为多专业合作制定诊断和治疗算法提供了契机。
