Early detection is crucial, as some PRDs can lead to sight-threatening complications, such as retinal detachment, if left unmanaged. Due to a paucity of research regarding PRDs and their association with axial length (AL) and refractive error (RE) in young Australian adults, this study aimed to investigate the prevalence of PRDs in this population and establish whether AL and RE could help predict the likelihood of PRD occurrence. Methods: A cross-sectional study was conducted on a mixed population (n = 221) of Australian adults aged 18 to 40. Demographic data, RE, AL, and a series of ultra-widefield (UWF) retinal images were obtained from participants\u2019 undilated eyes using the Zeiss ClarusTM 500. Results: The overall PRD prevalence was 8.15% (n = 442 eyes). Binary logistic regression revealed that a longer AL was a more significant factor in increasing the risk of PRD development across all myopia classifications compared to emmetropia than RE. The likelihood of a PRD was 50% at an AL of 26.9 mm and \u22126.50D of myopia, and 95% at 29.6 mm and \u221211.00D. Conclusions: PRD prevalence was lower than reported in other global studies, perhaps reflecting the diverse ethnic makeup of the cohort. While our study supports the conventional understanding that longer ALs, and high myopia are key risk factors for developing a PRD, it also provides new insights into the likelihood of detecting a PRD at a given AL or RE in a mixed population. This information is crucial for eye care practitioners, enabling early identification of at-risk individuals and screening for PRDs that may increase the risk of retinal detachment.<\/jats:p>","DOI":"10.3390\/jcm14103501","type":"journal-article","created":{"date-parts":[[2025,5,16]],"date-time":"2025-05-16T10:24:02Z","timestamp":1747391042000},"page":"3501","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Exploring the Risk: Peripheral Retinal Degenerations in Young Australian Adults"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3121-7491","authenticated-orcid":false,"given":"Natalie Ann","family":"Watt","sequence":"first","affiliation":[{"name":"School of Medicine (Optometry), Faculty of Health, Deakin University, 75 Pigdons Road, Geelong 3216, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4274-8725","authenticated-orcid":false,"given":"Nicholas","family":"Hockley","sequence":"additional","affiliation":[{"name":"School of Medicine (Optometry), Faculty of Health, Deakin University, 75 Pigdons Road, Geelong 3216, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3762-0911","authenticated-orcid":false,"given":"James Andrew","family":"Armitage","sequence":"additional","affiliation":[{"name":"School of Medicine (Optometry), Faculty of Health, Deakin University, 75 Pigdons Road, Geelong 3216, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,5,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"153","DOI":"10.1016\/j.optom.2013.08.003","article-title":"Prevalence of asymptomatic ocular conditions in subjects with refractive-based symptoms","volume":"7","author":"Michaud","year":"2014","journal-title":"J.
