Electronic databases, including PubMed, Web of Science, Embase, and Cochrane Library, were comprehensively searched for published studies comparing retinal microvasculature characteristics between eyes with BD and controls. Continuous variables were calculated using the mean difference (MD) with 95% confidence interval (CI). Review Manager software (version 5.30) was used to conduct statistical analysis. A total of 13 eligible studies involving 599 eyes with BD and 622 control eyes were included in the meta-analysis. The pooled results showed that the macular whole enface superficial and deep vessel density (VD) values measured by OCTA were significantly lower in eyes with BD than in control eyes (superficial VD: MD\u2009=\u2009\u2212\u20093.05, <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.00001; deep VD: MD\u2009=\u2009\u2212\u20094.05, <jats:italic>P<\/jats:italic>\u2009=\u20090.0004). The foveal superficial and deep VD values were also significantly lower in the BD group than in the control group (superficial VD: MD\u2009=\u2009\u2212\u20091.50, <jats:italic>P<\/jats:italic>\u2009=\u20090.009; deep VD: MD\u2009=\u2009\u2212\u20094.25, \u2212\u2009\u2009=\u20090.03). Similarly, the analysis revealed a significant reduction in the parafoveal superficial and deep VD in eyes with BD than in control eyes (superficial VD: MD\u2009=\u2009\u2009\u2212\u20093.68, <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.00001; deep VD: MD\u2009=\u2009\u2212\u20094.95, <jats:italic>P<\/jats:italic>\u2009=\u20090.0007). In addition, the superficial and deep foveal avascular zones (FAZs) were significantly larger in patients with BD than in controls (superficial FAZ: MD\u2009=\u20090.06, <jats:italic>P<\/jats:italic>\u2009=\u20090.02; deep FAZ: MD\u2009=\u20090.12, <jats:italic>P<\/jats:italic>\u2009=\u20090.03). The present meta-analysis found that macular whole enface VD, foveal VD, and parafoveal VD were lower in eyes with BD, and the FAZ was larger in patients with BD. The findings suggest that OCTA can assist clinicians in diagnosing and monitoring the status of patients with BD.<\/jats:p>","DOI":"10.1038\/s41598-021-04730-6","type":"journal-article","created":{"date-parts":[[2022,1,14]],"date-time":"2022-01-14T11:02:40Z","timestamp":1642158160000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Retinal microvasculature features in patients with Behcet\u2019s disease: a systematic review and meta-analysis"],"prefix":"10.1038","volume":"12","author":[{"given":"Kai-bao","family":"Ji","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhe","family":"Hu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qing-lin","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hai-feng","family":"Mei","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yi-qiao","family":"Xing","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2022,1,14]]},"reference":[{"key":"4730_CR1","doi-asserted-by":"publisher","first-page":"823","DOI":"10.1007\/s10067-010-1430-6","volume":"29","author":"F Davatchi","year":"2010","unstructured":"Davatchi, F. et al.
