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 main limitations of our study are small sample size and lack of ultrasonography of the ophthalmic artery and other ocular blood vessels.
The resistivity index of ophthalmic artery showed an inverse correlation with mean arterial pressure of pregnant women.
GROSS ANATOMY AND CLINICAL CORELATION: The vessels passing through the superior orbital fissure and the cranioorbital foramen contribute to arterial supply of anterior part of dura of middle cranial fossa and form anastomoses between ophthalmic artery and middle meningeal artery or dural branches of internal carotid artery.
The use of Ophthalmic artery chemosurgery (OAC) is rapidly gaining popularity as the mainstay disease intervention and has completely transformed the treatment and prognosis of retinoblastoma since its introduction.11 In the span of the last decade, the treatment algorithms of retinoblastoma management, and even its classification has seen a complete overhaul due to the dramatic results produced by OAC and intravitreal chemotherapy.
The study of Doppler velocimetry of the ophthalmic artery was performed on admission of volunteers in CH-FUU.
Caption: Figure 2: CT angiogram head and neck (continued): note the absence of the left internal carotid artery intracranially and poor opacification of the left ophthalmic artery. There is collateral supply to the left middle cerebral artery from the left posterior cerebral artery (a) and the anterior communicating artery (b).
Careful inspection of regional vasculature including ophthalmic artery and posterior ciliary arteries is required to exclude known causes of vascular occlusion.
However, there have been several documented cases of ophthalmic artery vasospasm following FESS thought to be secondary to direct injection of epinephrine into the ethmoidal artery [5].
The authors concluded that secondary injury to the optic nerve and direct injury to the ICA and ophthalmic artery might occur during surgical procedures due to variation in the ACP.
Acute complications of endovascular treatment include distal thromboembolic events (occlusion of the central retinal artery, ischemic stroke due to potential anastomosis between the IMA and the ophthalmic artery) and local tissue infarct.
The aim of this study was to investigate the association of selected lipid and vascular parameters with retrobulbar blood flow velocities and resistance indices in the ophthalmic artery (OA), the central retinal artery (CRA) and the posterior ciliary arteries (PCA): nasal (NPCA) and temporal (TPCA), in the POAG patients.
(3) Superomedial orbital injury can lead to hemorrhage and vision loss because the ophthalmic artery courses through this area and branches into the anterior and posterior ethmoid arteries.
