Showing an interindividual variability of about 1:7, the optic disc area is correlated with various other variables. This study evaluated whether it is associated with the size of the cornea. For 634 normal eyes of 350 subjects and 1,727 glaucomatous eyes of 942 patients, the optic disc area was measured on color stereo photographs and correlated with the radius of the anterior corneal curvature. The latter was compared with the diameters of the cornea for 50 eyes. Highly myopic eyes were excluded. We found that the optic disc size was significantly and positively correlated with the radius of the anterior corneal curvature, which was correlated with the corneal diameters: the larger the optic disc, the larger the curvature radius and the larger the corneal diameters. The results indicate that large optic discs occur preferentially in eyes with flat and large corneas.
视盘面积存在个体间约1:7的变异性，它与其他多种变量相关。本研究评估了它是否与角膜大小有关。对350名受试者的634只正常眼和942名患者的1727只青光眼眼，在彩色立体照片上测量视盘面积，并将其与角膜前表面曲率半径相关联。将后者与50只眼的角膜直径进行比较。高度近视眼被排除在外。我们发现视盘大小与角膜前表面曲率半径显著正相关，而角膜前表面曲率半径又与角膜直径相关：视盘越大，曲率半径越大，角膜直径也越大。结果表明，大视盘更常见于角膜扁平且较大的眼睛。
