Abstract:
Objective:To explore the feasibility and conformity of cone contrast test (CCT) and pseudoisochromatic plate test applied in medical selection of pilot.Methods:One hundred and sixteen male students were selected from pilot candidates by stratified sampling method. All students were tested the pseudoisochromatic plate test and the red, green, and blue cone contrast sensitivity and were divided into normal group, color weakness group and color blindness group according to the results of the pseudoisochromatic plate test. The students with a CCT score below 75 were judged as color vision anomalopia. The coincidence rates of the 2 detection results were compared and analyzed.Results:There were 76 students in normal group, 9 students in color weakness group and 31 students in color blindness group. Students with color vision abnormalities were mainly characterized by red-green color blindness and green color weakness, manifested by a significant decrease in CCT scores of red and green ( P=0.012 or <0.001), but there was no significant difference in the blue CCT scores among 3 groups (both P>0.05). The CCT scores of normal students were not less than 75 points, which meant that the compliance rate was 100%. The proportion of students in the color blindness group below 75 points was 29/31 (with a conformity rate of 93.5%), while the proportion in the color weakness group was 2/9. Conclusions:The conclusions of CCT and pseudoisochromatic plate test for identifying color blindness and normal students are basically consistent, but the conformity rate for identifying color weakness assessment by pseudoisochromatic plate test is relatively low. It is suggested that CCT would be the complement for identifying color weakness and marginal color vision abnormalities in the medical selection for pilot.
