To describe the clinical features of combined central retinal artery and vein occlusion (CCRAVO).<jats:italic>Methods<\/jats:italic>. This retrospective study included 33 admitted patients (33 eyes) who had CCRAVO. Clinical data, such as age, gender, best-corrected visual acuity (BCVA), intraocular pressure (IOP), findings on fundus color photography and fundus fluorescein angiography (FFA), and information about follow-up, were collected and analyzed.<jats:italic>Results<\/jats:italic>. The age of the patients with CCRAVO ranged from 22 to 78 years, with a mean of 48.8\u2009\u00b1\u200914.1 years. At presentation, BCVA of the involved eyes ranged from no light perception (NLP) to 20\/20. In addition, 45.5% (15\/33) of the eyes had BCVA of finger counting (FC) or below, whereas 12.1% (4\/33) had BCVA of 20\/60 or above. The IOP was lower in the involved eyes than in the fellow eyes (15.0\u2009\u00b1\u20093.0\u2009mmHg vs. 16.4\u2009\u00b1\u20092.3\u2009mmHg,<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\"><mml:mrow><mml:mi>p<\/mml:mi><mml:mo>=<\/mml:mo><mml:mn>0.03<\/mml:mn><\/mml:mrow><\/mml:math>). Ophthalmoscopic examination showed changes in both central retinal artery occlusion (CRAO) and central retinal vein occlusion (CRVO), including retinal hemorrhage, retinal ischemic whitening, optic disc hyperemia and\/or edema, venous dilation and tortuosity, cotton wool spot (CWS), and Roth\u2019s spot. FFA showed prolonged arm-to-retina time (ART) and retinal arteriovenous passage time (RAP) (17.1\u2009\u00b1\u20094.9\u2009s and 12.1\u2009\u00b1\u20098.8\u2009s, respectively). Capillary nonperfusion (CNP) was seen in 21 eyes (63.6%), and in 14 (42.2%) of these, CNP was larger than 10 disc areas. At 2 to 3 weeks after presentation, BCVA improved in 23 eyes (71.9%) and further deteriorated in 5 eyes (15.6%). Retinal ischemic whitening improved in more than half of the eyes, whereas retinal hemorrhage increased in nearly half of the eyes. Follow-up ranged from 6 to 56 months. Seven patients were lost to follow-up. At final follow-up, six eyes had a visual acuity of 20\/60 or greater, but 6 eyes had FC or worse. Four eyes developed neovascularization on follow-up.<jats:italic>Conclusion<\/jats:italic>. CCRAVO is a sight-threatening entity. Manifestations of CRAO and CRVO can be seen simultaneously in the early stage of disease, and CRVO may play a more important role in the development of CCRAVO.<\/jats:p>","DOI":"10.1155\/2019\/7202731","type":"journal-article","created":{"date-parts":[[2019,10,9]],"date-time":"2019-10-09T23:34:05Z","timestamp":1570664045000},"page":"1-7","source":"Crossref","is-referenced-by-count":15,"title":["Clinical
