Eye POCUS in the ED

How can you better differentiate the causes of floaters in patients? What are the US features of RD vs PVD vs vitreous syneresis?
Dr Ang Joo Shiang was the first to show me how sounding from head to toe can be valuable in timely diagnostics, and it was a great pleasure learning from him. He introduced me to eye ultrasound, and this case write-up that we published in the US Annals of Emergency Medicine not only taught me about differentials to floaters and the approach to eye US, but also illustrated how POCUS in ED is not limited to critical care use.
