Introduction: Bi-orbital distance and inter-orbital distance are two of the most important anthropometric parameters. Distance varies with race, regions within the same race & period in evaluation. Anthropometric study of orbit is of immense importance on account of its various implications in medical science, ranging from ophthalmic surgery, facial surgery and for forensic record. It is also helpful in plastic surgery (reconstructive surgery) and is used to treat congenital or post traumatic facial disfigurements successfully. The aim of the study was to investigate the orbital anthropometric variations in the normal population.

Materials and methods: The study was conducted on hundred human dry skulls in the department of anatomy, S.N medical college Agra. Bi-orbital distances and inter-orbital distances were measured directly by using digital vernier calipers.

Results: In the current study, the mean bi-orbital distance was 93.29±4.37 mm and the inter-orbital distance was 19.79±2.39 mm.

Conclusions: The findings of our study provide a database to determine normal inter orbital distance and bi-orbital distance. The BOD and IOD can be utilized by ophthalmologists, in reconstructive cosmetic surgeries of face and by forensic experts.
