Sex Determination by Morphometry of Eyes

ABSTRACT

Background: Facial anthropometrics are affected byvarious factors such as age, sex, ethnicity,socioeconomic status, environment and region. Theanthropometric analysis of face is essential forcraniofacial plastic and reconstructive surgeries. Aim &Objectives: The purpose of this study was to create abaseline data in determining the sex of the people fromIndia and Malaysia depending on morphometry of eyes.Material and Methods: A total of 100 Malaysians and100 South Indians were enrolled for the study. Variousmorphometric measurements of eyes were taken usingDigital Vernier caliper. The data were analyzed byindependent t test for comparison of sides and one wayANOVA to find out the significance among the sex andpopulations. Results:The height of upper and lower eyelid were higher in females as compared to that of maleswhereas depth of eyes and interpupillary distance werehigher in males than in females and thus sexualdimorphism exists. Fissure height and biocular widthwere more in Indian males when compared to Indianfemales. Fissure height and interocular width weremore in Malaysian female when compared to othergroups. Indian males and females differed significantlyin upper and lower eye lids height from Malaysianmales and females. All eye morphometric parametersexcept interpupillary distance were increased inMalaysians when compared to Indians thus ethnicvariations also exist. Conclusion: The facial aesthesis ishighly contributed by eye appearance and symmetry,facial rejuvenation by a plastic surgeon requiresmorphometric data of eye.
