Researches on a unilaterally blue-blinded rhesus monkey.

Abstract:

:Psychophysical measures of hue (wavelength) discrimination and spectral sensitivity were collected over a 3-year-period on a rhesus monkey whose right eye had been exposed to intense blue light 10 years prior and had shown a pronounced loss of blue sensitivity in an increment-threshold, spectral-sensitivity task. Hue discrimination, to a somewhat greater degree than spectral sensitivity, revealed large differences between the normal and blue-exposed eye. The difference limens were in some cases 100 nm for the blue-exposed eye compared to 10-15 nm for the normal eye. The hue-discrimination functions from the blue-exposed eye were similar in form to those from human tritanopes (blue-blind humans), and those from the monkey's normal eye were similar to those from normal humans. Detailed functions, where the variable wavelength was shorter as opposed to longer than the reference wavelength, were shown separately for each of the monkey's eyes; those from the blue-exposed eye were very similar to analogous functions from the one case where they have been shown separately for a human tritanope.
