A Study of Orbital Index

Yashaswini Shetty, Vandana Blossom

Abstract :

The orbit is the bony socket in the skull where the eye and its appendages are situated. In the adult human, the volume of the orbit is 30 to 32 ml, of which the eye occupies only 1/5th of the space. The orbits are conical or four side pyramidal cavities, which open on either side of nose in the face. Each consists of a base, an apex and four walls. The main function of the orbital bony socket is to give protection to the eye. Orbital measurements vary in different races of mankind. Its measurements are better understood by knowing orbital index. Orbital index of the person is must to do any operations related to orbit for the specialists like ophthalmologists, oral maxillofacial surgeons and neurosurgeons. Anthropology helps us to understand the anatomic structures of the orbit, and constitutes the technique of expressing makeover of human body and skeleton. For these reasons knowing the orbital index of different races by doing the regional studies is must for the better treatment.The present study was aimed at documenting standard values of orbital indices in a south Indian group and compå it with available data from other populations of the world. These would be very useful in anthropological studies, craniofacial surgery and diagnosis of craniofacial anomalies.
