Colour vision tests Flashcards
what is a protan described as
a general term stating that the long cone photo-pigment is different from normal
what is a deutan described as
a general term stating that the medium cone photo-pigment is different from normal
what is a tritan described as
a general term stating that the short cone photo-pigment is different from normal
what is the name if someone who has a missing long/L photo-pigment cone
protanope
what is the name if someone who has a missing medium/M photo-pigment cone
deutranope
what is the name if someone who has a missing short/S photo-pigment cone
tritanope
what is the name if someone who has one of their L, M or S cones missing
dichromat
what is the name if someone who has all three cones S, M and L present, but one is anomalous (different from normal)
trichromat (S, M or L spectral sensitivity is anomalous)
what is is called if someone has an anomalous L cone spectral sensitivity
protanomalous
what is is called if someone has an anomalous M cone spectral sensitivity
deutranomalous
what is is called if someone has an anomalous S cone spectral sensitivity
tritanomalous
what is a normal trichromat
there are 3 cones with L, M and S in the ‘normal group’
what is a cone monochromat
when two cones are missing
what is a rod monochromat
when all three cones are missing
list the three main colour vision tests
- ishihara
- anomoloscope
- 100 hue and D15
which type of plates does the ishihara test use
pseudoisochromatic plates
which colour vision test uses colour matching
the anomoloscope
which test uses confusion lines
100 hue and D15
