The infraorbital vessels are found in the inferior orbital fissure, and travel down the infraorbital groove into the infraorbital canal and exit through the infraorbital foramen.Inferior division of ophthalmic vein passes through the inferior orbital fissure. It is formed by the sphenoid bone and maxilla.he infraorbital vessels are found in the inferior orbital fissure, and travel down the infraorbital groove into the infraorbital canal and exit through the infraorbital foramen.
The orbit, which protects, supports, and maximizes the function of the eye, is shaped like a quadrilateral pyramid, with its base in plane with the orbital rim. Seven bones conjoin to form the orbital structure, as shown in the image below.he superior orbital fissure is bounded by the lesser and greater wings of the sphenoid. The greater wing of the sphenoid, the maxilla, and the palatine bones of the orbit form the boundaries of the inferior orbital fissure. The optic canal is at the apex of the orbit and lies within the sphenoid bone.
