It is frequently used to evaluate for vitreous hemorrhage, foreign bodies, retinal detachment, optic neuritis and posterior vitreous detachment; however, it can also be used to evaluate for a central retinal artery occlusion (CRAO). A POCUS can reveal a hyperechoic density in the optic nerve sheath just proximal to the retinal surface, and this is referred to as a retrobulbar \u2018spot sign\u2019 (RBSS). We present the case of an 88-year-old male that presented to our community ED with a painless loss of vision to his right eye. A POCUS revealed an RBSS of the central retinal artery and he was subsequently diagnosed with a CRAO. At his 1-month follow-up, he has regained light perception and 15% of his vision, however, remains with significant visual impairment.<\/jats:p>","DOI":"10.1093\/omcr\/omab038","type":"journal-article","created":{"date-parts":[[2021,6,18]],"date-time":"2021-06-18T08:00:08Z","timestamp":1624003208000},"source":"Crossref","is-referenced-by-count":5,"title":["Painless loss of vision: rapid diagnosis of a central retinal artery occlusion utilizing point-of-care ultrasound"],"prefix":"10.1093","volume":"2021","author":[{"given":"Gregory M","family":"Taylor","sequence":"first","affiliation":[{"name":"Assistant Professor of Clinical Emergency Medicine, Indiana University School of Medicine, IU Health Ball Memorial Hospital, Muncie, IN, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel","family":"Evans","sequence":"additional","affiliation":[{"name":"Emergency Medicine Physician at Mercy Medical Center, Cedar Rapids, IA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert P","family":"Doggette","sequence":"additional","affiliation":[{"name":"Assistant Professor of Clinical Emergency Medicine, Indiana University School of Medicine, IU Health Ball Memorial Hospital, Muncie, IN, USA"},{"name":"Methodist Hospital, Indianapolis, IN, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ryan C","family":"Wallace","sequence":"additional","affiliation":[{"name":"Assistant Professor of Clinical Emergency Medicine, Indiana University School of Medicine, IU Health Ball Memorial Hospital, Muncie, IN, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew T","family":"Flack","sequence":"additional","affiliation":[{"name":"Assistant Professor of Clinical Emergency Medicine, Indiana University School of Medicine, IU Health Ball Memorial Hospital, Muncie, IN, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sarah K","family":"Kennedy","sequence":"additional","affiliation":[{"name":"Associate Professor of Clinical Emergency Medicine and faculty for the Emergency Ultrasound Fellowship Program, Indiana University School of Medicine, Methodist Hospital, Indianapolis, IN, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2021,6,18]]},"reference":[{"key":"2021070812430088200_ref1","first-page":"6","article-title":"Cilioretinal arteries and retinal arterial occlusion","volume":"157","author":"Brown","year":"2014","journal-title":"Arch Ophthalmol"},{"key":"2021070812430088200_ref2","first-page":"943","article-title":"Central retinal artery occlusion treated with oxygen: a literature review and treatment algorithm","volume":"39","author":"Murphy-Lavoie","year":"2012","journal-title":"Undersea and Hyperbaric Med"},{"key":"2021070812430088200_ref3","doi-asserted-by":"publisher","first-page":"496","DOI":"10.1111\/j.1442-9071.2010.02280.x","article-title":"Clinical characteristics and outcome of current standard management of central retinal artery occlusion","volume":"38","author":"Rudkin","year":"2010","journal-title":"Clin Experiment Ophthalmol"},{"key":"2021070812430088200_ref4","doi-asserted-by":"publisher","first-page":"1148","DOI":"10.1001\/jamaneurol.2015.1578","article-title":"Intravenous fibrinoglytic therapy in central retinal artery occlusion.
