Hemodynamic impacts of flow diverter devices on the ophthalmic artery

Journal of Translational Medicine, 2019
Background Flow diverter devices are increasingly used for endovascular treatment of internal carotid artery aneurysms. Treatment of ophthalmic segment aneurysms with flow diverter devices also includes coverage of the ophthalmic artery but may result in

Proper ophthalmic artery aneurysms. [PDF]

Surg Neurol Int, 2023
Background: The ophthalmic segment of the internal carotid artery (ICA) represents a common site for cerebral aneurysms. However, aneurysms of the ophthalmic artery (OphA) itself represent rare lesions and have been associated with trauma and flow-related lesions such as arteriovenous fistulas or malformations.

Orbital apex syndrome and ophthalmic artery occlusion caused by acute sinusitis [PDF]

BMC Ophthalmology
Background Acute sinusitis is a common condition that rarely leads to severe complications like orbital apex syndrome and ophthalmic artery occlusion, which can cause significant vision loss and require prompt diagnosis and treatment. Case presentation A

Studies on the Effects of Hypercholesterolemia on Mouse Ophthalmic Artery Reactivity [PDF]

Diseases, 2023
Atherogenic lipoproteins may impair vascular reactivity, leading to tissue damage in various organs, including the eye. This study aimed to investigate whether ophthalmic artery reactivity is affected in mice lacking the apolipoprotein E gene (ApoE ...

Relationship between the Direction of Ophthalmic Artery Blood Flow and Ocular Microcirculation before and after Carotid Artery Stenting

Journal of Ophthalmology, 2016
When internal carotid artery stenosis is accompanied by ocular ischemic syndrome, intervention is recommended to prevent irreversible visual loss. In this study, we used laser speckle flowgraphy to measure the ocular microcirculation in the optic nerve ...

Ophthalmic artery originating from contralateral internal carotid artery associated with ipsilateral agenesis of internal carotid artery [PDF]

Radiology Case Reports
Congenital absence of the internal carotid artery is a rare anatomical variant. The primarily reported origins of the ophthalmic artery associated with this variant are the posterior communicating, middle cerebral, and external carotid arteries.

Ophthalmic artery occlusion following neuro-embolization of the external carotid artery, a case report

BMC Ophthalmology, 2017
Background Embozene® is a new neuroembolizing microsphere used to reduce intraoperative bleeding for head and neck tumours. We report a case of iatrogenic ophthalmic artery occlusion after Embozene® embolization of the external carotid artery (ECA). Case

Dolichoectasia of the ophthalmic artery: a case report on the treatment strategy in endovascular therapy and literature review [PDF]

BMC Cardiovascular Disorders
Background Dolichoectasia is a rare arterial condition characterized by the dilatation, tortuosity, and elongation of cerebral blood vessels. The vertebrobasilar artery and internal carotid artery are the common sites of dolichoectasia.

Ophthalmic artery angioplasty for age-related macular degeneration

Journal of NeuroInterventional Surgery, 2022
Background There is considerable overlap of contributors to cardiovascular disease and the development of age-related macular degeneration (AMD). Compromised ocular microcirculation due to aging and vascular disease contribute to retinal dysfunction and ...

Ophthalmic artery Doppler in prediction of pre‐eclampsia: insights from hemodynamic considerations

Ultrasound in Obstetrics and Gynecology, 2021
We followed with great interest the studies of Sapantzoglou1, Sarno2 and colleagues from the Fetal Medicine Foundation (FMF) group who introduced ophthalmic artery (OA) Doppler as a new tool in their multivariate prediction models for pre-eclampsia (PE ...
