ophthalmic artery

A branch of the internal carotid artery; it leaves of the cranial cavity through the optic foramen with the optic nerve. In the orbit, it branches to form the lacrimal, supraorbital, anterior and posterior ethmoidal, medial palpebral, supratrochlear, dorsal nasal, meningeal, muscular, and ciliary arteries. In addition, it gives rise to the central retinal artery.

The fact that the intraocular pressure has not shown significant changes, despite the increased diameter of the external ophthalmic artery, it may be understood by the existence of intrinsic mechanisms of control of the intraocular pressure in that case.
It is known that the sildenafil citrate causes significant increase in the blood flow speed of the ophthalmic artery, dilation of the retina arteries and increase in the choroidal and retinal vessels flow (MCCULLEY et al.
36) Administration through the ophthalmic artery results in the passage of chemotherapeutic agents to other ocular and orbital arteries including the supraorbital artery, posterior and anterior ciliary arteries, which can cause transient side effects in the forehead area such as hyperemia, eyelid edema, ptosis and chemosis.

The ophthalmic artery, which is responsible for the orbital blood supply, is a direct branch of the internal carotid artery and is part of the shunt between the internal and external carotid arteries.
Facial lesions around the midline have bilateral arterial supply, forehead lesions are usually supplied by supraorbital branch of the ophthalmic artery, as well as by the branch of external carotid artery Pi.
When the definitive ophthalmic artery differentiates as a branch from the terminal part of the internal carotid artery it communicates with supraorbital branch of stapedial artery, distally this becomes the lacrimal artery.
For example, one specimen was prepared to show ophthalmic artery crossing optic nerve from lateral to medial side (figure no.
DISCUSSION: The ophthalmic artery is the first branch of the internal carotid artery and enters the orbit underneath the optic nerve through the optic canal.
