Interpupillary distance of females of Arab origin.

We have investigated the distant and near interpupillary distance (IPD) of three groups of females of Arab origin. Average values and range of values have been determined for children, young adults, and older adults. Average distant interpupillary distance (FIPD) measurements are compared to those of females of Caucasian (European and American), African-American, and Chinese (Hong Kong and mainland China) origin. Different experimental techniques and some unavailable information about previously studied subjects make conclusive statements about the ethnic variation of IPD difficult to draw.
