Hue discrimination and colour thresholds in persons with peripheral visual neuron damage

R Lukauskienec, V Viliunas

Computerised Farnsworth - Munsell 100-hue (F - M 100) test and the colour threshold test were used to examine patients with peripheral visual neuron damage. Hue discrimination and colour determination thresholds were measured in eleven subjects with damage of peripheral visual neurons and in thirty healthy subjects with normal colour vision. Testing of each person was repeated several times. Eight persons were subjected to a series of tests before and after treatment. The results were analysed according to: (i) mean data of F - M 100 test error scores; (ii) mean data of colour determination thresholds; (iii) colour deficiency type according F - M 100 test; (iv) colour deficiency type according colour-thresholds test. We found that: (i) a correlation exists between F - M 100 test mean error score and the mean colour threshold (coefficient of correlation 0.85); (ii) F - M 100 test mean error score and the mean colour threshold were significantly worse (more than by a factor of 2) in persons with peripheral visual neuron damage than in healthy subjects; (iii) persons who received some type of treatment in 10% of cases showed better results in the last series of tests.
