Introduction: Orbital index could be defined as the percentage ratio of the orbital height to the orbital width. Aim: The purpose of the present study is to investigate the prevalent orbital class among the Igbo Ethnic group. Materials and Methods: A total number of 350 radiographic films of subjects aged between less than 1 year and 79 years were collected, comprising 217 males and 133 females, from the National Orthopaedic Hospital, Enugu, Nigeria from which orbital index was calculated. The orbits were classified accordingly based on the orbital index into microseme, mesoseme or megaseme. The frequency of each orbital class was presented in percentage. Result: The results showed that the prevalent orbital class among the Igbo Ethnic group is microseme. Conclusion and Recommendation: However, whereas microseme was found to be predominant, the other orbital classes were also found within the same population. It is recommended that further studies should be carried out in other populations to find out the incidence of different orbital classes instead of concluding that an entire population has a particular orbital class based on the mean.
