Background: The face is the most distinctive part of the human body. Of all areas on the face, the bilateral orbital regions which are located in the upper half of the face act as a strong influence in the perception of facial attractiveness, esthetic criteria, and “ideal” features of any certain nation. This fact increases the needs for interorbital anthropometry or interocular distances (IODs) which refers to the measurements of the human far interpupillary distance (FIPD), near interpupillary distance (NIPD), outer canthal distance (OCD), and inner canthal distance (ICD) among individuals of different age, sex, and ethnicity. Objective: To assess the normal ranges of interorbital anthropometric values among adult healthy Sudanese population and to define the effects of age, gender, and tribal ethnicity on interorbital anthropometry. Materials and Methods: Systematic interorbital anthropometric measurements were done in 920 Sudanese adults aged 20–85 years. Parameters included were FIPD, NIPD, OCD, and ICD across age, sex, and tribal ethnic perspective of the study subjects. Comparisons were made between their gender, age, and tribal ethnicity using the Chi-square test. Results: The study included 565 female (61.4%) and 355 male (38.6%) subjects with mean age of 48 ± 20 (range 20–85) years. Significant age, gender, and ethnical dimorphism were noted in the following parameters. OCD (male: 92.23 mm; female: 90.79 mm), FIPD (male: 63.20 mm; female: 61.57 mm), NIPD (male: 59.34 mm; female: 57.73 mm), and ICD (male: 34.30 mm; female: 33.00 mm). Conclusion: Significant interorbital measurement differences were found between Sudanese males and females in different age and ethnic groups. The present study suggests that age, gender, and ethnicity should be considered in Sudanese esthetic criteria and “ideal” features in any cosmetic or reconstructive orbital surgery. To individualize the treatment planning and diagnosis, it is important for the surgeons to have knowledge of these local Sudanese interorbital norms.
