The mean age was 53.75\u2009\u00b1\u200917.11\u00a0years. The New Rural Cooperative Medical System (NCMS) played the most important role in reimbursement (60.32%) for secondary glaucoma-related medical expenses. The predominant occupation was \u201cfarmer\u201d (53.41%). Neovascularization and trauma were the leading causes of secondary glaucoma. Cases of trauma-induced glaucoma decreased substantially during the coronavirus disease 2019 (COVID-19) pandemic. An education level of senior high school or above was uncommon. Ahmed glaucoma valve implantation was the most commonly performed surgery. At the final follow-up, the overall intraocular pressure (IOP) in patients with vascular disease- and trauma-related secondary glaucoma was 19.53\u2009\u00b1\u200910.20\u00a0mmHg, 20.26\u2009\u00b1\u200911.75\u00a0mmHg, and 16.90\u2009\u00b1\u20096.72\u00a0mmHg, while the mean visual acuity (VA) was 0.33\u2009\u00b1\u20090.32, 0.34\u2009\u00b1\u20090.36, and 0.43\u2009\u00b1\u20090.36. In 814 (70.29%) eyes, the VA was\u2009&lt;\u20090.01. Effective preventive measures for at-risk populations, increased NCMS coverage and the promotion of higher education are necessary. These findings will help ophthalmologists detect secondary glaucoma early and manage it in a timely manner.<\/jats:p>","DOI":"10.1038\/s41598-023-34872-8","type":"journal-article","created":{"date-parts":[[2023,5,25]],"date-time":"2023-05-25T10:02:39Z","timestamp":1685008959000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Clinical analysis of secondary glaucoma in Central China"],"prefix":"10.1038","volume":"13","author":[{"given":"Qian","family":"Liu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Changgeng","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenjun","family":"Cheng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaomei","family":"Feng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haijun","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoyuan","family":"Yang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yangzeng","family":"Dong","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2023,5,25]]},"reference":[{"key":"34872_CR1","first-page":"121","volume":"30","author":"HC Agarwal","year":"1982","unstructured":"Agarwal, H.
