Flashcards in Colour Vision Deck (12):
Limited discrimination, but still contains all three photopigments.
Sensitivity spectrum shifted to lower wavelengths, less sensitive to longer wavelengths. Red weak. Requires more red to match.
Sensitivity spectrums hifted to longer wavelengths. Green weak. Requires more green to match.
Inherited blue-yellow wavelength spectrum shift. More rare.
Rare condition of not being able to distinguish colours. They only have one retinal cone or lack all cone function/rod monochromat.
Red deficient/lack erythrolabe - sensitivity reduced in the higher wavelengths.
Green deficient/lack chlorolabe
Inherited blue-yellow deficiency
True/False: Nagel anomolascope can differentiate trichromacy and dichromacy.
TRUE: can distinguish between anomolous trichromacy and dichromat.
Most likely to have red/green colour defects?
Bilateral and stable usually.
Cause of acquired blue/yellow colour defects?
Outer retinal disease
