Macular optical coherence tomography (OCT) findings were classified into 5 groups preoperatively and 10 groups postoperatively. Best-corrected visual acuity (BCVA) were analyzed according to pre- and postoperative OCT. &lt;b&gt;&lt;i&gt;Results:&lt;\/i&gt;&lt;\/b&gt; From the preoperative OCT, normal fovea with\/without traction, normal fovea with preretinal hemorrhage, and tractional retinal detachment involving fovea showed an increase in BCVA after PPV (all &lt;i&gt;p&lt;\/i&gt; &lt; 0.05). Normal fovea, epiretinal membrane and macular thickening were common after surgery. Normal fovea, epiretinal membrane and edema outside of the fovea showed good visual prognosis (BCVA &gt;20\/50). Subfoveal fibrosis, macular hole, loss of foveal depression, and serous foveal detachment showed poor visual prognosis (BCVA &lt;20\/100). &lt;b&gt;&lt;i&gt;Conclusion:&lt;\/i&gt;&lt;\/b&gt; Macular structural changes were various after PPV, and visual prognosis correlated with these changes.<\/jats:p>","DOI":"10.1159\/000477826","type":"journal-article","created":{"date-parts":[[2017,7,20]],"date-time":"2017-07-20T21:02:28Z","timestamp":1500584548000},"page":"186-195","source":"Crossref","is-referenced-by-count":9,"title":["Structural Changes of the Macula on Optical Coherence Tomography after Vitrectomy for Proliferative Diabetic Retinopathy"],"prefix":"10.1159","volume":"238","author":[{"given":"Jong Chan","family":"Im","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jong Ho","family":"Kim","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6911-3765","authenticated-orcid":false,"given":"Dong Ho","family":"Park","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jae Pil","family":"Shin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2017,7,21]]},"container-title":["Ophthalmologica"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/477826","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/477826","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T16:33:32Z","timestamp":1745426012000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000477826"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017]]},"references-count":0,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2017,10,12]]},"published-print":{"date-parts":[[2017,10,17]]}},"URL":"https:\/\/doi.org\/10.1159\/000477826","archive":["Portico"],"relation":{},"ISSN":["0030-3755","1423-0267"],"issn-type":[{"type":"print","value":"0030-3755"},{"type":"electronic","value":"1423-0267"}],"subject":[],"published":{"date-parts":[[2017]]}}}
