Intercanthal and interpupillary distance in the black population.

Intercanthal distance is an important measurement in the evaluation of congenital deformities and posttraumatic telecanthus. In this study 100 black patients (71 female and 29 male) were measured for intercanthal and interpupillary distance. For the overall group the mean intercanthal distance was 33.9 +/- 3.0 mm; previous studies of white persons and mixed populations indicate an average of 32 +/- 3 mm. The mean interpupillary distance for this study was 63.7 +/- 3.7 mm; previous studies indicate an average of 63 +/- 3 mm. This study suggests that the intercanthal and interpupillary distances in blacks are similar to findings of previous studies on whites and mixed populations.
