An automated static perimeter/adaptometer is described which measures thresholds with lights of 2 wavelengths. The instrument uses light-emitting diodes to produce the stimuli and is controlled by a small computer, making it very suitable for clinical testing of large numbers of patients. The use of 2 LEDs with different peak emission wavelengths (530 and 660 nm) permits an assessment of the relative state of rod and cone mechanisms in a particular region of the retina either during dark adaptation or when the eye is fully dark adapted.
本文描述了一种自动静态视野计/自适应光度计,它可使用两种波长的光来测量阈值。该仪器使用发光二极管产生刺激,并由一台小型计算机控制,这使其非常适合对大量患者进行临床测试。使用具有不同峰值发射波长(530和660纳米)的两个发光二极管,可以在暗适应期间或眼睛完全暗适应时评估视网膜特定区域中视杆和视锥细胞机制的相对状态。
