Ocular Point of Care Ultrasound (POCUS) is a non-invasive, inexpensive, and rapid modality to establish diagnosis with reduced time to consultation and treatment. Methods: 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.\u00a0 Results: 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. Conclusion: 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.<\/jats:p>","DOI":"10.24908\/pocus.v6i2.14974","type":"journal-article","created":{"date-parts":[[2021,11,24]],"date-time":"2021-11-24T00:01:24Z","timestamp":1637712084000},"page":"73-75","source":"Crossref","is-referenced-by-count":13,"title":["Diagnosis of Central Retinal Artery Occlusion in the Emergency Department Using POCUS: A Case Series"],"prefix":"10.24908","volume":"6","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7887-972X","authenticated-orcid":false,"given":"Nicholas","family":"Cozzi","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kendall","family":"Stevens","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yeoshina","family":"Pillay","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Moore","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthew","family":"Flannigan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mariah","family":"Barnes","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthew","family":"Singh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Melisa","family":"Gagrica","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christian","family":"Kolacki","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jennifer","family":"Bach","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dale","family":"McNinch","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Drue","family":"Orwig","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeffrey","family":"Jones","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"10534","published-online":{"date-parts":[[2021,11,23]]},"container-title":["POCUS Journal"],"original-title":[],"link":[{"URL":"https:\/\/ojs.library.queensu.ca\/index.php\/pocus\/article\/download\/14974\/2021-06-02p73-75-pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/ojs.library.queensu.ca\/index.php\/pocus\/article\/download\/14974\/9880","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/ojs.library.queensu.ca\/index.php\/pocus\/article\/download\/14974\/2021-06-02p73-75-pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,11,24]],"date-time":"2021-11-24T00:01:25Z","timestamp":1637712085000},"score":1,"resource":{"primary":{"URL":"https:\/\/ojs.library.queensu.ca\/index.php\/pocus\/article\/view\/14974"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,11,23]]},"references-count":0,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2021,11,23]]}},"URL":"https:\/\/doi.org\/10.24908\/pocus.v6i2.14974","relation":{},"ISSN":["2369-8543","2369-8543"],"issn-type":[{"value":"2369-8543","type":"electronic"},{"value":"2369-8543","type":"print"}],"subject":[],"published":{"date-parts":[[2021,11,23]]}}}
