我们设计了一种彩色视频切线屏幕，它利用视频显示器的微机控制，产生与10英尺朗伯处的白色环境亮度相匹配的彩色周边测试物体。通过动态视野检查法测定不同颜色饱和度的视野等值线。这种形式的彩色视野检查40例开角型青光眼患者和20例疑似青光眼患者的每只眼。对前23只有明显青光眼视野缺损的患眼，采用Goldmann视野计对彩色视野检查和常规视野检查的结果进行盲法比较。在这23只眼中，14只眼睛的彩色视野检查与亮度视野检查一样好，2只眼睛的敏感度较低，7只眼睛的敏感度较高。所有通过常规视野检查可检测到的缺陷均通过颜色方法成功证明。与传统的亮度视野计相比，当通过颜色方法映射时，这种缺陷通常看起来在程度上更大。
A color video tangent screen has been devised, using microcomputer control of a video display to produce colored perimetric test objects matched in luminance to a white surround at 10-foot lamberts. Perimetric isopters for varying degrees of color saturation were determined by kinetic perimetry. This form of color perimetry was used to examine one eye of each of 40 patients with open-angle glaucoma as well as 20 glaucoma-suspect patients. For the first 23 eyes with manifest glaucomatous visual field defects, a masked comparison was made between the results of color perimetry and conventional perimetry with a Goldmann perimeter. For these 23 eyes, color perimetry did as well as luminance perimetry in 14, was less sensitive in 2, and was more sensitive in 7. All defects that were detectable by conventional perimetry were successfully demonstrated by the color method. Such defects often appeared to be greater in extent when mapped by the color method as compared to conventional luminance perimetry.
