Spectral sensitivity of human visual pathway and its clinical application 1. increment threshold spectral sensitivity of normal subjects
Clinical test on opponent-color system is useful for the early diagnosis of acquired [human] retinal diseases as well as congenital color defects. A clinical use for this practical method was determined. A circular 1.2.degree. test flash was projected from behind on a translucent thin plate; this was constanty illuminated by background circular 8.degree., white or yellow light. Using a white background (1000 td [target density] and 5,900.degree. K) and 40 ms test flashes, a normal spectral sensitivity curve was obtained. This curve had 3 peaks, near 440, 540 and 600 nm. Test flashes of 200 ms disclosed 3 peaks which were clearly more normal. Yellow background light (1200 td) and 200 ms test flashes were the best combinations to obtain the sensitivity curve of opponent-color channels.
