Selected subjects were interviewed and subjected to optometric and ophthalmic examinations.\nRESULTS: The age and sex standardized prevalence of pterygium and pinguecula was 3.64% [95% confidence interval (CI): 2.94%\u20134.49%] and 55.57% (95%CI: 52.89%\u201358.22%), respectively. The prevalence of pterygium was 4.52% (95%CI: 3.5%\u20135.81%) in men and 2.79% (95%CI: 1.97%\u20133.94%) in women and the prevalence of pinguecula was 64.56% (95%CI: 60.92%\u201368.03%) in men and 46.72% (95%CI: 43.74%\u201349.72%) in women. According to the results of multiple logistic regression, pinguecula had a significant correlation with male sex [odds ratio (OR): 2.21, 95%CI: 1.63\u20132.99] and education level (OR: 0.52, 95%CI: 0.35-0.77) and pterygium had a significant relationship with male sex (OR: 2.2, 95%CI: 1.38\u20133.52), socioeconomic status (SES, OR: 0.5, 95%CI: 0.26\u20130.97), education level (OR: 0.22, 95%CI: 0.08\u20130.61).\nCONCLUSION: The prevalence of pinguecula and pterygium in this study are lower than other studies. Sex, SES, and education level are the risk factors of the prevalence of pinguecula and pterygium.<\/jats:p>","DOI":"10.18240\/ijo.2025.04.17","type":"journal-article","created":{"date-parts":[[2025,3,21]],"date-time":"2025-03-21T07:55:13Z","timestamp":1742543713000},"page":"699-706","source":"Crossref","is-referenced-by-count":2,"title":["Prevalence of pterygium and pinguecula and their risk factors: Tehran Geriatric Eye Study"],"prefix":"10.18240","volume":"18","author":[{"name":"Noor Research Center for Ophthalmic Epidemiology, Noor Eye Hospital, Tehran 1983963113, Iran","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alireza","family":"Hashemi","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hassan","family":"Hashemi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Noor Ophthalmology Research Center, Noor Eye Hospital, Tehran 1983963113, Iran","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pooneh","family":"Malekifar","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Noor Ophthalmology Research Center, Noor Eye Hospital, Tehran 1983963113, Iran","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mehdi","family":"Khabazkhoob","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Department of Medical Surgical Nursing, School of Nursing and Midwifery, Shahid Beheshti University of Medical Sciences, Tehran 1968653111, Iran","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\/4\/20250417.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,3,21]],"date-time":"2025-03-21T07:55:37Z","timestamp":1742543737000},"score":1,"resource":{"primary":{"URL":"http:\/\/ies.ijo.cn\/gjyken\/ch\/reader\/view_abstract.aspx?file_no=20250417&flag=1"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,4,18]]},"references-count":0,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2025,4,18]]}},"URL":"https:\/\/doi.org\/10.18240\/ijo.2025.04.17","relation":{},"ISSN":["2222-3959","2227-4898"],"issn-type":[{"value":"2222-3959","type":"print"},{"value":"2227-4898","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,4,18]]}}}
