Abstract

Bilateral duplication of optic canal is considered to be a rare anomaly. Literature is available & cases are reported showing bilateral & unilateral duplication of the optic canal in dry human skulls. In the present study 2 cases (1 male & 1 female) bilateral duplicate optic canals were found out of 316 macerated adult skulls of both sexes. A bony septa separated the main canal from the duplicate canal. The larger canal usually carries the optic nerve with the meninges & the smaller one transmits the ophthalmic artery.

This study has been made & reported as a rare anomaly.
