A survey of color vision defects was performed on a random sample of 138 Santiago male school children aged 14-15 years. Over-all incidence of red-green defects was found to be 4.34 percent. Blue-yellow minor defects were found in 17 cases (12 percent). The following major defects were found: extreme tritanomaly plus extreme tetartanomaly (1 case), and extreme tetartanomaly plus weak tritan defects (2 cases).

These results suggest a probable incidence of 2.16 percent of congenital blue blindness in the general male population of Santiago, Chile.
