Luminance measurements of targets and backgrounds revealed differences for various types of perimetric instruments. A lack of uniform testing conditions for instruments of the same design was also noted. Of the instruments measured, hemispheric-projection perimeters seemed to provide the most repeatable test conditions.
对目标和背景的亮度测量揭示了各种类型视野计之间的差异。还注意到相同设计的仪器缺乏统一的测试条件。在所测量的仪器中,半球形投射视野计似乎能提供最可重复的测试条件。
