Thirty randomly chosen eyes from 30 subjects without ocular disease were examined: the mean disc area (2.20 \u00b1 SD 0.58 mm2), the mean cup area (0.36 \u00b1 0.29 mm2) and the mean rim area (1.83 \u00b1 0.37 mm2) were evaluated. All the measurements were performed by two independent observers and were corrected to the actual size by measuring refraction and axial length of each eye. A linear correlation among disc areas (r=0.71), cup areas (r=0.93) and rim areas (r=0.74) between the two observers was found. Furthermore, a highly significant correlation between disc area and rim area was observed (r=0.90) together with a correlation between the disc and cup area (r=0.82). A correlation between disc area and axial length was finally found (r=0.59). The neuroretinal rim area has been expressed as a percentage of the total disc area. Percent values ( \u00b1 SD) were clustered around a mean of 84.83 \u00b1 8.8%. Despite their high degree of repeatability, our data are slightly different from those previously reported by other authors.<\/jats:p>","DOI":"10.1159\/000309957","type":"journal-article","created":{"date-parts":[[2010,3,31]],"date-time":"2010-03-31T11:12:55Z","timestamp":1270033975000},"page":"40-45","source":"Crossref","is-referenced-by-count":6,"title":["Neuroretinal Rim Area in Normal Eyes: A Study on a Randomized Group of 30 Subjects"],"prefix":"10.1159","author":[{"given":"Ferdinando G.","family":"Bottoni","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pietro M.","family":"Gonnella","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alessandro S.","family":"Porta","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Giangiacomo G.","family":"Consalez","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2010,3,31]]},"container-title":["Ophthalmologica"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000309957","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,2]],"date-time":"2026-05-02T07:06:26Z","timestamp":1777705586000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000309957"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010,3,31]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000309957","archive":["Portico"],"relation":{},"ISSN":["0030-3755","1423-0267"],"issn-type":[{"value":"0030-3755","type":"print"},{"value":"1423-0267","type":"electronic"}],"subject":[],"published":{"date-parts":[[2010,3,31]]}}}
