103 normal and 86 open-angle glaucoma optic disks were evaluated with the microcomputer image analyser. Except for the diameter and area, all other parameters of the normal disk differed significantly from those of the glaucomatous disk. The cup/rim area ratio in glaucoma was significantly larger, while the cup/disk area ratio was moderately so, indicating that the former was more useful in the early diagnosis of glaucoma. The microcomputer image analyser was reliable and accurate, also capable of processing blurred images from varying exposure and focussing. The quotient between the horizontal and vertical C/D ratios was a relatively stable value with changing glaucomatous cupping.
使用微机图像分析仪对103个正常视盘和86个开角型青光眼视盘进行了评估。除直径和面积外，正常视盘的所有其他参数与青光眼视盘的参数均有显著差异。青光眼患者的杯/盘面积比显著更大，而杯/视盘面积比则中度增大，这表明前者在青光眼的早期诊断中更有用。微机图像分析仪可靠且准确，还能够处理来自不同曝光和聚焦的模糊图像。随着青光眼性视杯凹陷的变化，水平和垂直杯盘比之间的商是一个相对稳定的值。
