Anthropometric Study of Canthal Index among Yorubas of Owo Origin in Ondo State, Nigeria

Abstract

The canthus is the angle where the upper and lower eyelids converge. The terms "inner canthus" and "outer canthus" refer to the medial and lateral canthuses, respectively. The aim of this study is to determine the inner, and outer canthal distance as well as canthal index between males and females of Owo origin in Ondo State, Nigeria. This study adopted the descriptive cross-sectional survey of the quantitative design. For each subject, the inner canthal distance and outer canthal distance was measured and recorded while the canthal index was calculated. Data obtained for this research was analysed using descriptive statistics (Mean and Standard deviation) to test the hypotheses of this study and inferential statistics (t-test) to describe the nature of the data. The statistical test was done with the aid of the Statistical Package for Social Science (SPSS version 24.0). Results showed that in the outer canthal distance, the mean value in male was statistically significantly greater than in females (p<0.05). Results also showed that in the inner canthal distance, the mean value in male was statistically significantly greater than in females (p<0.05). It was concluded that there was a significant sexual dimorphism in canthal parameters among Owo males and female population.
