Fifty-six pediatric participants (112 eyes) clinically diagnosed high myopia were recruited and were treated by PSR in Shanghai Children\u2019s Hospital from June 1, 2021 to May 1, 2023. The average age ranged from 5.42 to 14.83\u00a0years (mean 8.83\u00a0years) and mean follow up duration was 8.7\u00a0months (3\u201324\u00a0months). The axial length (AL) was significantly shortened after PSR (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05). The spherical equivalent (SE) and the best-corrected visual acuity (BCVA) were also improved without severe rejection in the follow-up. Compared with baseline, angio-OCT parafoveal vessel indices including vascular area density (VAD) and vascular skeleton density (VSD) on the superficial capillary plexus layer (SCPL), as well as VAD and vessel perimeter index (VPI) on the deep capillary plexus layer (DCPL), were significantly increased after PSR surgery (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05). VPI on the SCPL, vascular diameter index (VDI) and VSD on the DCPL were also improved without statistical difference after PSR. The VSD on SCPL, VAD on DCPL of the right eyes and the VPI on SCPL of the left eyes were significantly increased after PSR (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05). PSR surgery can shorten the AL and can stable BCVA and SE in high myopia children. The angio-OCT parameters indicated that the retinal microcirculation supply was significantly improved after PSR.<\/jats:p>","DOI":"10.1038\/s41598-024-67078-7","type":"journal-article","created":{"date-parts":[[2024,7,17]],"date-time":"2024-07-17T03:31:49Z","timestamp":1721187109000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Clinical outcomes of posterior scleral reinforcement in Chinese high myopia children"],"prefix":"10.1038","volume":"14","author":[{"given":"Haiyun","family":"Ye","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruizhi","family":"Tang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wangyi","family":"Fang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yue","family":"Di","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tong","family":"Qiao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2024,7,17]]},"reference":[{"issue":"4","key":"67078_CR1","doi-asserted-by":"publisher","first-page":"49","DOI":"10.1167\/iovs.61.4.49","volume":"61","author":"AEG Haarman","year":"2020","unstructured":"Haarman, A.
