Ocular and facial anthropometry of young adult males of Arab origin.

Other investigators have provided normal values of facial and ocular dimensions of subjects of different ethnic backgrounds. Our main reason for carrying out this study was to provide a data base of similar measurements for the male Arab (Saudi) population. A projected photographic technique was used. Measurements from the photographs were transformed to real life distances by multiplying by a constant factor. The results of our investigations show that Japanese have wider inter-outer canthal distance (IOCD) than Arabs and Caucasians, both of whom have similar IOCD. Arabs have wider inter-inner canthal distance (IICD) than Caucasians. African-Americans and Japanese have wider inter pupillary distance (IPD) than Arabs. Percentile values of the measured distances will aid in syndrome diagnosis among male Arabs.
