Eight-seven clusters, each consisting of 50 people aged \u226550y, were selected by probability-proportionate-to-size sampling. Three outreach teams conducted door-to-door visits. Visual acuity (VA) was measured using a tumbling E chart. Lens status and causes of VI were assessed by ophthalmologists for individuals with a VA of &lt;6\/12 in either eye. A standardized questionnaire was used to collect information about cataract surgeries.\nRESULTS: Of 4350 eligible individuals, 4120 were examined with a 94.7% response rate. Age- and gender-adjusted prevalence of blindness, SVI, and VI were 0.5% (95%CI, 0.3%\u20130.7%), 0.7% (95%CI, 0.4%\u20131.0%), and 4.8% (95%CI, 4.2%\u20135.5%), respectively. Age was associated with an increased prevalence of VI, and the most common cause of VI was untreated cataracts, with the main barriers to cataract surgery being a lack of knowledge or awareness about cataracts. Of the 415 eyes operated on for cataracts, 68 (16.4%) eyes had a poor outcomes (VA&lt;6\/60) and 303 (73.0%) had a good outcomes (VA&gt;6\/18).\nCONCLUSION: Prevalence rates of blindness, SVI, and VI in Yueqing are lower than other reported Chinese population-based studies. Cataracts remain the most common cause of blindness and VI.<\/jats:p>","DOI":"10.18240\/ijo.2025.03.19","type":"journal-article","created":{"date-parts":[[2025,2,20]],"date-time":"2025-02-20T07:52:31Z","timestamp":1740037951000},"page":"510-517","source":"Crossref","is-referenced-by-count":0,"title":["Rapid assessment of avoidable blindness in Yueqing, an economically developed area in eastern China"],"prefix":"10.18240","volume":"18","author":[{"name":"National Clinical Research Center for Ocular Diseases, Eye Hospital, Wenzhou Medical University, Wenzhou 325027, Zhejiang Province, China","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chun-Jie","family":"Lu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuan-Bo","family":"Liang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"National Clinical Research Center for Ocular Diseases, Eye Hospital, Wenzhou Medical University, Wenzhou 325027, Zhejiang Province, China","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yi-Ze","family":"Chen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"National Clinical Research Center for Ocular Diseases, Eye Hospital, Wenzhou Medical University, Wenzhou 325027, Zhejiang Province, China","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Di","family":"Song","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"National Clinical Research Center for Ocular Diseases, Eye Hospital, Wenzhou Medical University, Wenzhou 325027, Zhejiang Province, China","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yi-Hua","family":"Tang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"National Clinical Research Center for Ocular Diseases, Eye Hospital, Wenzhou Medical University, Wenzhou 325027, Zhejiang Province, China","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juan","family":"Gu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"National Clinical Research Center for Ocular Diseases, Eye Hospital, Wenzhou Medical University, Wenzhou 325027, Zhejiang Province, China","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jia","family":"Qu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"National Clinical Research Center for Ocular Diseases, Eye Hospital, Wenzhou Medical University, Wenzhou 325027, Zhejiang Province, China","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7543","container-title":["International Journal of Ophthalmology"],"original-title":[],"link":[{"URL":"http:\/\/ies.ijo.cn\/en_publish\/2025\/3\/20250319.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,2,20]],"date-time":"2025-02-20T07:52:55Z","timestamp":1740037975000},"score":1,"resource":{"primary":{"URL":"http:\/\/ies.ijo.cn\/gjyken\/ch\/reader\/view_abstract.aspx?file_no=20250319&flag=1"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,3,18]]},"references-count":0,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2025,3,18]]}},"URL":"https:\/\/doi.org\/10.18240\/ijo.2025.03.19","relation":{},"ISSN":["2222-3959","2227-4898"],"issn-type":[{"value":"2222-3959","type":"print"},{"value":"2227-4898","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,3,18]]}}}
