Spectral sensitivity of human visual pathway and its clinical application 1. increment threshold spectral sensitivity of normal subjects

, : Spectral sensitivity of human visual pathway and its clinical application 1. increment threshold spectral sensitivity of normal subjects. Nippon Ganka Gakkai Zasshi 86(2): 197-202

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 test flash was projected from behind on a translucent thin plate; this was constanty illuminated by background circular, white or yellow light. Using a white background (1000 td [target density] and 5, 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.

Fluctuating asymmetry (FA) in morphological traits can vary with the size of characters and the mode of selection acting on them. In a previous study, mid-leg tarsal FA (tarsal spine number and tarsal length) in the water boatman Callicorixa vulne...
