“…While both globe and retrobulbar structures can be readily identified using ocular POCUS, evaluation for CRAO is only sparsely described in emergency medicine case reports or series. 7 Additionally, there are no emergency medicine accounts of serial color Doppler exams performed on patients with the diagnosis of CRAO enhanced by the calculation of an RI. There are several ultrasound findings that may be present in the ocular POCUS examination of a patient suffering from a CRAO, including the following: an absence of pulsatile central retinal artery blood flow using color and pulsed wave Doppler, an increased RI measured using pulsed wave Doppler, and the retrobulbar spot sign.…”

Introduction: Vision loss is a symptom found frequently in patients presenting to the emergency department (ED). Central retinal artery occlusion (CRAO) is an uncommon yet time-sensitive and critical cause of painless vision loss in which delayed diagnosis can lead to signiﬁcant morbidity. Emergency medicine literature documents the ability to diagnose a CRAO using ultrasound by identifying the hyperechoic thrombus coined the retrobulbar spot sign.Case Report: We present the case of a patient presenting with painless monocular vision loss for which CRAO was diagnosed in the ED using point-of-care ultrasound enhanced by the utilization of serial Doppler examinations as well as calculation of the central retinal artery resistive index.Conclusion: Despite the pre-existing literature on point-of-care ultrasound investigation of central retinal artery occlusion, there are no emergency medicine case reports describing serial examination of the central retinal artery by spectral Doppler or calculation of arterial resistive index to improve this evaluation and monitor progression of the pathology.
