视频眼底描记仪通过同时立体图像记录视盘的地形图，这些图像在微型计算机的帮助下被存储和分析。该信息用于生成垂直杯盘比、垂直视盘直径、杯体积和神经视网膜边缘面积。为了确定数据的可靠性，记录5名患者各1只眼睛的信息10次，以确定照相间误差方差。对5名患者的每一张照片进行10次分析，以确定可归因于重复分析同一张照片的照片内差异。对于这些测量，照相间和照相内的变异系数分别为2-18%和2- 7%。
The videoophthalmograph records the topography of the optic disk via simultaneous stereoscopic images which are stored and analyzed with the help of a microcomputer. This information is used to generate the vertical cup-disk ratio, the vertical optic disk diameter, the cup volume, and the neuroretinal rim area. To determine the reliability of the data, information was recorded for 1 eye of each of 5 patients 10 times to determine the interphotographic error variance. One photograph was analyzed for each of 5 patients 10 times to determine the intraphotographic variance attributable to repeated analysis of the same photograph. The interphotographic and intraphotographic coefficients of variation were 2-18% and 2-7%, respectively, for these measurements.
