One hundred and three color vision defective subjects were screened from 3456 middle school students with pseudoisochromatic plate test One hundred subjects out of them were further examined with a test battery including Panel D—15 and FM 100—hue test and Neitz anomaloscope test It was found that there were 21 protanopes (P), 3 extremely protanomalous (EPA), 13 protanomalous (PA), 25 deutenopes (D), 5 extremely deuteranomalous (EDA), 28 deuteranomalous (DA), 6 unclassified subjects in our investigation. The proportion of various types of congenital color vision defects was P: EPA: PA: D: EDA: DA=1.00:0.14:0.62:1.19:0.24:1.33.
