Methods: This multicenter observational study included 15 patients (9 males, 19 eyes) with coexisting GA and peripheral atrophy. All eyes were imaged with Ultra-widefield Optos California (Optos, PLC, Dunfermline, Scotland) to acquire ultra-widefield (200\u00b0) color and FAF images centered on the fovea, superior, inferior, nasal, and temporal sectors. The extent of GA in the central FAF image and the peripheral atrophic areas in the peripheral FAF images were measured by manually defining the boundaries of the atrophic regions using the \u201cROI free\u201d function integrated into the device software. The values obtained were then analyzed and correlated. Results: The mean \u00b1 standard deviation (SD) GA size was 13.9 \u00b1 15.0 mm2 (range: 1.8\u201371.3 mm2) and the total peripheral atrophy was 51.0 \u00b1 68.3 mm2 (range: 1.4\u2013292.1 mm2). The topographic analysis showed that the mean \u00b1 SD of superior peripheral atrophy was 9.0 \u00b1 20.6 mm2, temporal atrophy was 30.5 \u00b1 55.9 mm2, inferior atrophy was 9.3 \u00b1 16.3 mm2, and nasal atrophy was 1.8 \u00b1 3.9 mm2. GA size was significantly correlated with total peripheral atrophy (Rho = 0.463, p = 0.046) and temporal peripheral atrophy (Rho = 0.474, p = 0.040), whereas no correlations were found with peripheral atrophy in the remaining sectors. Conclusion: Ultra-widefield autofluorescence is a valuable technique for visualizing and assessing the extent of macular and peripheral atrophy. Macular atrophy correlates significantly with total and temporal peripheral atrophy but demonstrates no significant correlation with atrophy in the remaining sectors. <\/jats:p>","DOI":"10.1159\/000544958","type":"journal-article","created":{"date-parts":[[2025,4,8]],"date-time":"2025-04-08T16:09:18Z","timestamp":1744128558000},"page":"168-174","source":"Crossref","is-referenced-by-count":0,"title":["Geographic Atrophy and Peripheral Atrophy: Quantitative Analysis with Ultra-Widefield Autofluorescence"],"prefix":"10.1159","volume":"248","author":[{"given":"Daniele","family":"De Geronimo","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mariacristina","family":"Parravano","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Riccardo","family":"Sacconi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9916-8895","authenticated-orcid":false,"given":"Eliana","family":"Costanzo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Monica","family":"Varano","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Giuseppe","family":"Querques","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2025,4,8]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.3390\/antiox11112189"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1016\/s0039-6257(05)80092-x"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1167\/iovs.63.11.4"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1016\/S2214-109X(13)70145-1"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1167\/iovs.12-9711"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1016\/j.ophtha.2013.11.023"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1016\/j.ophtha.2016.12.002"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1097\/IAE.0b013e318164a907"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1016\/j.oret.2019.04.014"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.4274\/tjo.galenos.2019.00359"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1016\/j.ophtha.2015.03.005"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1016\/j.ophtha.2016.12.004"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1016\/j.ophtha.2012.12.002"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.3390\/jcm10173993"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0177207"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcm.2016.02.012"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1159\/000439358"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1111\/j.1755-3768.2012.02434.x"}],"container-title":["Ophthalmologica"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/oph\/article-pdf\/doi\/10.1159\/000544958\/4363677\/000544958.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000544958","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,7,1]],"date-time":"2025-07-01T16:04:25Z","timestamp":1751385865000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000544958"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,4,8]]},"references-count":18,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2025,7,2]]}},"URL":"https:\/\/doi.org\/10.1159\/000544958","archive":["Portico"],"relation":{},"ISSN":["0030-3755","1423-0267"],"issn-type":[{"type":"print","value":"0030-3755"},{"type":"electronic","value":"1423-0267"}],"subject":[],"published":{"date-parts":[[2025,4,8]]}}}
