The optic canal transmits the optic nerve and ophthalmic artery(option-E).
<h3>What is ophthalmic artery?</h3>
The internal carotid artery's first branch is the ophthalmic artery. It separates right near the cavernous sinus. The orbit, meninges, face, and upper nose are all supplied by the numerous branches that the ophthalmic artery produces. Vision may be compromised if the ophthalmic artery is blocked.
The lacrimal gland, conjunctiva, and eyelids are all supplied by it. In order to supply the posterior uveal tract, the ophthalmic artery releases a number of posterior ciliary arteries that cross the sclera. Being end vessels, the posterior ciliary vessels are susceptible to sudden occlusion, which can result in infarction in the choroid region.
