It runs through the inferior orbital fissure, orbit, infraorbital canal then the infraorbital foramen. Here it gives off the anterior superior alveolar artery which supplies the anterior teeth and the anterior part of the maxillary sinus.

Detailed explanation-3: -The arterial input to the eye is provided by several branches from the ophthalmic artery, which is derived from the internal carotid artery in most mammals (Fig 2.2, left). These branches include the central retinal artery, the short and long posterior ciliary arteries, and the anterior ciliary arteries.
