Central retinal artery occlusion

Journal of the American College of Emergency Physicians, 1979
Central retinal artery occlusion is characterized by sudden, painless visual loss due to blockage of retinal blood flow. It has been reported in all age groups including children but is most frequent in the sixth decade. Both thrombosis and embolism have been suggested as possible mechanisms.

Central Retinal Artery Occlusion

Ophthalmic Surgery, Lasers and Imaging Retina, 1987
ABSTRACT Injecting steroid crystals into orbital inflammatory lesions produces a prolonged, high level of drug activity at the target tissue. This technique appears helpful in controlling orbital inflammations in problem cases while reducing the chance of steroid related systemic side effects.

Thrombolysis for Central Retinal Artery Occlusion

Journal of Neuro-Ophthalmology, 2007
Central retinal artery occlusion (CRAO) frequently causes severe and irreversible visual loss. For many years, various conservative treatments have been proposed for acute CRAO, but their efficacy remains unproven. Over the past 20 years, CRAO has also been treated with thrombolytic agents administered intravenously or intra-arterially.

Traumatic Central Retinal Artery Occlusion

Ophthalmologica, 2010
A healthy 6-year-old boy with a clinical picture of central retinal artery occlusion (CRAO) of his left eye is presented here. The underlying cause was a trauma to the boy’s left cheek some 6 months earlier. Possible pathophysiological mechanisms are discussed.

Central Retinal Artery Occlusion

New England Journal of Medicine, 2007
A 76-year-old man with hypertension presented with a sudden, painless, and profound loss of vision in the right eye. Visual acuity was light perception only in the affected eye, with a positive relative afferent pupillary defect. Ophthalmoscopic examination revealed diffuse retinal whitening, constriction of the arteriole and venule with segmentation ...

Occlusion of the Central Retinal Artery in Migraine

New England Journal of Medicine, 1964
RETINOVASCULAR phenomena during migraine are not uncommon, but permanent sequelae are rare. These are usually ascribed to some concomitant organic lesion such as aneurysm, tumor, syphilis, cerebrovascular accidents, hypertension, aberrant artery pressure or encephalitis.

Experimental Central Retinal Artery Occlusion

Archives of Ophthalmology, 1968
In a series of 22 eyes of 19 squirrel monkeys, the central retinal artery (CRA) was ligated within the orbit. Serial fundus photography and fluorescein angiography demonstrated that this experimental model closely resembled the human disease. Histologically, there was massive swelling of the inner retinal layers followed by necrosis. Fine-structurally,

Updates in Central Retinal Artery Occlusion

Journal of Neuro-Ophthalmology
Background: Central retinal artery occlusion (CRAO) is a vision-threatening neuro-ophthalmic emergency, analogous to acute ischemic stroke. Delayed presentation, limited therapeutic options, and lack of randomized prospective trials continue to restrict effective treatment.

Cilioretinal Artery Occlusion with Central Retinal Vein Occlusion

Optometry and Vision Science, 1999
ABSTRACT: Background: Combined cilioretinal artery and retinal vein occlusions are infrequently documented retinal vascular disorders of speculative origin. Occlusion of the cilioretinal artery is believed to result from either mechanical compression of the artery as a result of an increase in ...
