In order to detect incipient visual field defects, the present study aimed particularly to determine function of normal values depending on age and eccentricity. &lt;i&gt;Methods:&lt;\/i&gt; A test group (n = 83) of ophthalmologically and clinically unremarkable subjects 18\u201374 years of age was examined with the \u2018Centerfield\u2019 perimeter. A brief introductory program was first used to familiarize each test person with the situation. Then values in the central visual field (30&lt;i&gt;Results:&lt;\/i&gt; Age-related normal values were calculated both as group averages and as lines of regression by statistical analysis of the resulting data. In contrast to other perimetric studies, decreases in LDS at different test points for persons aged 20 years to persons over 60 were not linear. &lt;i&gt;Conclusions:&lt;\/i&gt; Age-related normal values should be reviewed for other perimeters.<\/jats:p>","DOI":"10.1159\/000048306","type":"journal-article","created":{"date-parts":[[2003,4,15]],"date-time":"2003-04-15T13:07:10Z","timestamp":1050412030000},"page":"96-100","source":"Crossref","is-referenced-by-count":5,"title":["Age-Corrected Normal Values for Perimetry"],"prefix":"10.1159","volume":"216","author":[{"given":"Thomas-Michael","family":"Wohlrab","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carl","family":"Erb","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jens Martin","family":"Rohrbach","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2002,4,2]]},"container-title":["Ophthalmologica"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/48306","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/48306","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,24]],"date-time":"2025-04-24T04:02:17Z","timestamp":1745467337000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000048306"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2002]]},"references-count":0,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2002,4,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000048306","archive":["Portico"],"relation":{},"ISSN":["0030-3755","1423-0267"],"issn-type":[{"type":"print","value":"0030-3755"},{"type":"electronic","value":"1423-0267"}],"subject":[],"published":{"date-parts":[[2002]]}}}
