The pyradimal shaped bony orbit communicates with middle cranial fossa by means of optic canal which transmits optic nerve and ophthalmic artery.

Complete duplication, partial duplication, whether unilateral or bilateral duplication were studied. Results: Out of one hundred skull bones, in one case

Conclusion: The knowledge of duplication of optic canal increases the success rate of surgical procedures of optic canal and minimizes the risk of injury to optic nerve and ophthalmic artery.
