Superselective ophthalmic artery
chemotherapy as primary treatment for retinoblastoma (chemosurgery).
Microaneurysms, narrowing of the retinal arterioles, and venous dilation are observed on fundus examination due to decreased flow in the ophthalmic artery
Careful inspection of regional vasculature including ophthalmic artery
and posterior ciliary arteries is required to exclude known causes of vascular occlusion.
000 SD: Standard deviation; PSV (cm/s): Peak systolic velocity; EDV (cm/s): End-diastolic velocity; MV (cm/s): Mean velocity; PI: Pulsatility index; RI: Resistance index; OA: The ophthalmic artery
, CRA: The central retinal artery, TPCA: The temporal posterior ciliary artery, NPCA: The nasal posterior ciliary artery
Concerning the ultrasonography, the mean of the external ophthalmic artery
diameter before (basal) treatment was 2.
The ophthalmic artery
came from intracavernous carotid artery in few cases (26).
In both studies, chemotherapy was delivered locally either through the ophthalmic artery
for retinoblastoma or the basilar artery for DIPG.
One very particular blood vessel, which is called ophthalmic artery
(OA) exists in human being head.
Bilateral Ophthalmic Artery
Occlusion in Rhino-Orbito-Cerebral Mucormycosis.
of California, San Francisco) details the basic concepts and tenets of aneurysm microsurgery, various craniotomies and exposures for successful clipping, and microsurgical anatomy, dissection strategies, and clipping techniques for each of the seven most common aneurysm types: posterior and anterior communicating artery, middle cerebral artery, ophthalmic artery
, basilar bifurcation, pericallosal artery, and posterior inferior cerebellar artery aneurysms.
There have been some reports of central retinal or ophthalmic artery
occlusion and blindness.
A cerebral angiogram was performed, which was normal except for truncation of the ophthalmic artery
Although the ophthalmic artery
has anastomotic connections with some branches of the external carotid arteries, this may be insufficient to protect the optic nerve from ischemia if severe hypovolemic shock occurs.
The internal carotid artery (ICA) enters the cranial vault posterior to the eye orbit, supplying blood to the ophthalmic artery
before terminating into the middle cerebral artery (MCA) and the anterior cerebral artery (ACA).
Nasdaq: VASO) announced today that a study recently published by physician researchers in Germany demonstrated a significant increase in ophthalmic artery
blood flow velocities in patients with severe atherosclerotic disease.
