Hue discrimination under different illuminative levels. Colour perception was adversely affected by decreased illuminative level. Illuminative level of photopic and mesopic condition was 1000 lx and 40 lx, respectively. (a) In the control group, significant deterioration of hue perception under mesopic condition was found in bands of R-YR, Y-GY, G-BG, BG-B, B-PB and RP-R (p ≤ 0.002). (b) Preoperatively, the patient group manifested worse hue perception in colour bands of R-YR, G-BG, BG-B, B-PB, PB-P and RP-R (p ≤ 0.001). (c) In the postoperative phase, decline of hue perception was detected in the separate band of R-YR (p = 0.001). Error bars show standard deviation
