The cup-to-disc ratio and the neural rim area are used to detect glaucoma damage to the optic nerve. Both parameters are dependent on the size of the optic disc and on the number of optic nerve fibers. We compared the size of the disc in fundus photographs with the number of nerve fibers in 25 normal monkey eyes. The number of fibers increased linearly with an increasing disc area. One must know the size of the optic disc to evaluate properly the cup-to-disc ratio or neural rim area.
杯盘比和神经边缘面积用于检测青光眼对视神经的损害。这两个参数均取决于视盘大小和视神经纤维数量。我们比较了25只正常猴眼眼底照片中的视盘大小与神经纤维数量。纤维数量随视盘面积增加呈线性增加。要正确评估杯盘比或神经边缘面积，必须知道视盘大小。
