Determination of Interpupillary Distances Among Students of Igbo Origin in Madonna University, Elele, Rivers State, Port Harcourt, Nigeria

Pupillary distance (PD) or inter-pupillary distance (IPD) is the distance measured in millimeters between the centers of the pupils of the eyes. The present study evaluates the inter-pupillary distances amongst Madonna University undergraduates of Igbo origin. The sample size comprised of 125 Igbo males and 125 Igbo females which comprised only of young adults (18-25years). The modified Viktorin's method was used in the study. Measurements of interpupillary distances were taken by the use of a millimeter inter-pupillary distance ruler. This can be observed from figures 1, 2, 3, 4 and 5. The male mean value 36.53 was significantly higher than the female value 32:65 for the FIPD (far inter-pupillary distances). The difference between the NIDP (near inter-pupillary distances) and FIDP (Far inter-pupillary distances) was statistically significant in all particular age groups of either sex. The overall anatomical far inter-pupillary distance (FIPD) for the males was, on the average, wider than the near inter-pupillary distance (NIPD), with a difference of 6.7 mm in males and 5.6 mm in females. This study has established that there is a significant difference between the inter-pupillary distances among the Igbo male and female students of Madonna University, Elele campus, Rivers state, Nigeria
