5.5.8. D15 Saturated and D15 Desaturated Tests
The
D15 Tests is widely used in industries where colour decisions are critical. In a
quick, precise and easy way the test determines colour vision abnormalities and
checks patient’s ability to make color discrimination. The test can also be used to
determine eye diseases, diabetes, Parkinson's disease and the effects of various
pharmaceuticals on colour vision.
How it Works:
To do this test it is necessary to have USB mouse ( not
included ) and plug it into USB port 1 or 2.
The patient is presented one set of colour dots. The set there are 16 colour dots in
the centre of the screen and 1 pilot colour dot (see
Pic. 25. D15 Saturated Test and
Pic. 26 Desaturated Test)
Pic. 21. D15 Test
The patient is asked to arrange the dots so that the colours go smoothly from the
pilot colour dot. The closer the patient is to the correct sequence, the better his/her
colour discrimination.
