Anatomic Evaluation of the Ophthalmic Artery in Optic Canal Decompression: A Cadaver Study of 20 Optic Canals.

AIM A relationship was shown in this study between the optic canal and the ophthalmic artery by cadaver study. It is intended that the anatomical and histological values which we obtained can be used as a guide in surgery MATERIAL and METHODS: A surgical anatomical evaluation was made of twenty optic canals in ten cadavers fixed in 10% formaldehyde. These were evaluated together with measuremen...
