The results of the two tests were correlated (p=+0.768, P < 0.01) in that the higher the matching range on the P-N anomaloscope, the greater is the error score on the 100-Hue test in tobacco amblyopia. The matching range (t = 9.78, P < 0.001) and the 100-Hue test (t = 5.43, P < 0.001) score were significantly higher t…
