In total, 86 acute CRAO patients were included. Spectral-domain optical coherence tomography (SD-OCT), CFP, and MC examinations were taken at baseline. Based on the findings of these three examinations, CRAO was divided into three grades (incomplete, subtotal, and total). Based on OCT grading criteria, we qualitatively compared the ability of grading CRAO by CFP and MC. CRAO patient's visual acuity (VA) was obtained from the initial visit. The retinal thickness was measured by SD-OCT. Superficial capillary plexus (SCP) and deep capillary plexus (DCP) were obtained from optical coherence tomography angiography (OCTA) examinations. Quantitative data were compared across the three acute CRAO subgroups and against three examination findings.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>MC image had significantly higher power of acute CRAO detection than CFP (<jats:italic>P<\/jats:italic> = 0.03). In the same group of CRAO patients, there was no significant difference in VA when comparing OCT with the MC grading system or with the CFP grading system (all <jats:italic>P<\/jats:italic> &amp;gt; 0.05). Significant differences in VA were found between the three CRAO subgroups only under MC grading (<jats:italic>P<\/jats:italic> = 0.016). In incomplete CRAO patients, significant differences were found in central fovea thickness (CFT) when comparing OCT with the CFP grading system (<jats:italic>P<\/jats:italic> = 0.019). In the same group of CRAO patients, there was no significant difference in retinal thickness when comparing OCT with the MC grading system (All <jats:italic>P<\/jats:italic> &amp;gt; 0.05). Significance differences in CFT (<jats:italic>P<\/jats:italic> &amp;lt; 0.001), innermost retinal layer (IMRL; <jats:italic>P<\/jats:italic> &amp;lt; 0.01), middle retinal layer (MRL; <jats:italic>P<\/jats:italic> &amp;lt; 0.001), and outer retinal layer (ORL; <jats:italic>P<\/jats:italic> = 0.021) were found between the three CRAO subgroups by MC grading. Vessel density of SCP showed a statistically increased as the severity of three CRAO subgroups (<jats:italic>P<\/jats:italic> = 0.03), whereas DCP did not have significant differences (<jats:italic>P<\/jats:italic> = 0.745). Comparisons were made between the OCT grading method and the MC and CFP grading methods; there is no significant difference in vessel density of SCP and DCP (All <jats:italic>P<\/jats:italic> &amp;gt; 0.05).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The images obtained by MC are superior to those obtained by CFP in CRAO grading, retinal thickness, and vessel density measurement. MC imaging may be more capable of CRAO grading than OCT. We recommend MC imaging to determine CRAO severity to guide disease treatment and predict visual prognosis.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fnins.2024.1327806","type":"journal-article","created":{"date-parts":[[2024,4,10]],"date-time":"2024-04-10T05:04:26Z","timestamp":1712725466000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["Clinical application of multicolor scanning laser ophthalmology in diagnosis and grading of central retinal artery occlusion"],"prefix":"10.3389","volume":"18","author":[{"given":"Yuwei","family":"Wan","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ting","family":"Chen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ying","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yang","family":"Yang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yaqi","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuedan","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xuejie","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anhuai","family":"Yang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xuan","family":"Xiao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2024,4,10]]},"reference":[{"key":"B1","first-page":"283","article-title":"Multimodal imaging of acute central retinal artery occlusion","volume":"8","author":"Abdellah","year":"2019","journal-title":"Med.
