CT was measured pre\u2010 and postoperatively both subfoveally and in attached macular areas. Postoperatively, the CT in previously detached or attached Early Treatment Retinopathy Diabetic Study (ETRDS) macular areas and the choroidal luminal areas were assessed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The preoperative median subfoveal CT of 260\u2009\u03bcm (interquartile range (IQR)\u2009=\u2009151) was significantly reduced to 200\u2009\u03bcm (IQR\u2009=\u2009110) 1 month postoperatively (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001). Corresponding to attached macular areas, the preoperative median CT of 184\u2009\u03bcm (IQR\u2009=\u2009116) was significantly reduced to 155\u2009\u03bcm (IQR\u2009=\u2009103) 1 month postoperatively (<jats:italic>p<\/jats:italic>\u2009=\u20090.03). No significant changes in CT occurred from 1 to 12 months postoperatively, either in previously detached, median 163\u2009\u03bcm (IQR\u2009=\u200974) to 173\u2009\u03bcm (IQR\u2009=\u2009127), (<jats:italic>p<\/jats:italic>\u2009=\u20090.484), or in attached, 148\u2009\u03bcm (IQR\u2009=\u2009110) to 159\u2009\u03bcm (IQR\u2009=\u2009142), (<jats:italic>p<\/jats:italic>\u2009=\u20090,766) EDTRS areas. Median luminal areas of inner choroidal microvasculature and large choroidal vessels were 58.5% (IQR\u2009=\u20091.4) and 61.4% (IQR\u2009=\u20092.2) at 1 month, respectively, and stayed unchanged until 12 months postoperatively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>CT reduction 1 month after vitrectomy for fovea\u2010off RRD was more pronounced subfoveally than beneath attached macular areas. This finding could represent a normalization of a subfoveal choroidal swelling due to increased fluid absorption during RRD.

unchanged.<\/jats:p><\/jats:sec>","DOI":"10.1111\/aos.17441","type":"journal-article","created":{"date-parts":[[2025,1,18]],"date-time":"2025-01-18T11:04:14Z","timestamp":1737198254000},"page":"432-438","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Choroidal
