*  Central retinal artery occlusion - Wikipedia
Central retinal artery occlusion (CRAO) is a disease of the eye where the flow of blood through the central retinal artery is blocked (occluded). There are several different causes of this occlusion; the most common is carotid artery atherosclerosis. Central retinal artery occlusions cause sudden, acute, and painless loss of vision in one eye. Fundoscopic exam will show a red lesion, called a "cherry red spot," with surrounding pale retina (the pale color is caused by ischemia of the retina). The most common cause for CRAO is carotid artery atherosclerosis. In patients of 70 years of age and older, giant cell arteritis is more likely to be the cause than in younger patients. Other causes can include dissecting aneurysms and arterial spasms. The ophthalmic ...

*  Central Retinal Artery Occlusion - JOMTonline.com
What is Central Retinal Artery Occlusion?. The central retinal artery branches off the ophthalmic artery which in turn branches off the internal carotid artery. The central retinal artery is vital because it supplies blood to the inner two-thirds of the retina. . If the central retinal artery becomes occluded, there will be a sudden painless loss of vision in that eye.. Central retinal artery occlusion (CRAO) is generally due to an embolism including platelet-fibrin, cholesterol, or calcium plaque. The emboli break off vessel walls ...

*  The relation of retinal artery occlusion and carotid artery stenosis. | Stroke
We retrospectively studied 46 patients with symptomatic retinal artery occlusion and assessed the pattern and extent of carotid artery disease ipsilateral to the retinal artery occlusion. Ipsilateral internal carotid artery atherosclerotic lesions were virtually limited to the cervical arterial segment; 50% of such lesions were plaques or stenoses of less than or equal to 60%, whereas 15% of the angiograms were normal. No clinical features were significantly associated with a flow-limiting carotid stenosis of greater than 60%. Contrary to previous reports, the type of retinal artery occlusion, whether branch or central artery occlusion, was not predictive of severe underlying carotid stenosis or ...

*  Central Retinal Artery Occlusion
... is a pathological condition in which the arteries which carry blood to the eye become blocked resulting in sudden vision loss in the affected eye. The retina is a layer of nerves behind the inner eye who function is to sense light. The function of the retina is to transform images into signals which are sent to brain via the optic nerves and an individual is able to see the image. Thus, a blockage of the artery in the retina is potentially a serious condition. This blockage usually is caused due to a clot or fatty deposits in the blood vessels. Central Retinal Artery Occlusion is a condition which requires immediate medical attention because if the clot traverses and reaches the brain then it may result in a stroke ...

Blockage of arterial blood supply to the retina, usually as a result of thrombosis or embolism. The central retinal artery enters the eye at the optic disc and then divides into branches to supply different parts of the retina. Blockage of the central retinal artery (central retinal artery occlusion) usually results in sudden painless loss of vision. Blockage of one of the branches of the central retinal artery (branch retinal artery occlusion) results in ischaemia of the retina supplied by the occluded vessel and related visual field loss. ...

*  Spontaneous Central Retinal Artery Occlusion in a Teenager with Sickle Cell Trait - Semantic Scholar
Sickle cell trait (SCT) is traditionally considered a benign condition by ophthalmologists. Several studies have reported ocular complications in SCT, but these complications have been described as a consequence of trauma, exertion, and associated systemic disorders. We here in the report a case of an Arab teen boy, who presented with a sudden loss of vision in his left eye of 1 h duration. The ocular examination revealed acute central retinal artery occlusion. He underwent a series of laboratory and radiological investigations. The blood investigations revealed SCT and abnormal partial thromboplastin time. The fundus fluorescein angiography revealed abnormal retinal vascular perfusion. Marked blood rheological impairment and activation of the coagulation pathway can occur without any contributing factors in SCT leading to severe ocular complications. This is one of the young patients with spontaneous ...

*  O2.0 - hyperbaric oxygen therapy news: New on HyperbaricLink: Central Retinal Artery Occlusion (CRAO)
The retina consumes oxygen at a rate faster than any other organ in the body. It is highly sensitive to ischemia, or lack of blood supply. In the treatment of CRAO hyperbaric oxygen therapy has succeeded where others in the last 100 years have failed [UHMS]. But quick access to an emergency-ready chamber is a must. Or as [Medscape] puts it, "Hyperbaric oxygen therapy (HBOT) may be beneficial if begun within 2-12 hours of symptom onset. Institute treatment with other interventions first, as transport to a chamber may usurp precious time." Central retinal artery occlusion offers yet another good reason, then, for the healthcare community to demand 24/7 access to hyperbaric medicine ...

*  Intravenous fibrinolysis in acute non-arteritic central retinal artery occlusion - revisited | IOVS | ARVO Journals
Purpose : Central retinal artery occlusion (CRAO) is an ophthalmologic emergency that often results in severe loss of vision or even blindness. However, no evidence-based therapy exists for the treatment of non-arteritic CRAO. In previous prospective randomized trials (intra-arterial and intravenous fibrinolysis) so far only one patient has been treated within the first 4.5 hours after symptom onset. Methods : In this case series, we report on seven patients who received intravenous fibrinolysis within the first 4.5 hours after symptom onset. Results : The mean Log(MAR) visual acuity increased from 2.5 ("hand motion") (SD ± 0.23) to 1.1 ("20/250")(SD ± 0.76). Furthermore, the visual field improved dramatically in four out of seven patients. No adverse events were observed in this case series. The outcome was far superior compared to the results of previous trials in which lysis could not be performed so promptly. Conclusions : Intravenous ...

*  Ocular ischemic syndrome - Wikipedia
Ocular ischemic syndrome is the constellation of ocular signs and symptoms secondary to severe, chronic arterial hypoperfusion to the eye. Amaurosis fugax is a form of acute vision loss caused by reduced blood flow to the eye; it may be a warning sign of an impending stroke, as both stroke and retinal artery occlusion can be caused by thromboembolism due to atherosclerosis elsewhere in the body (such as coronary artery disease and especially carotid atherosclerosis). Consequently, those with transient blurring of vision are advised to urgently seek medical attention for a thorough evaluation of the carotid artery. Anterior segment ischemic syndrome is a similar ischemic condition of anterior segment usually seen in post-surgical cases. Retinal artery occlusion (such as central retinal artery ...

*  Retinal artery occlusion: Update | Public Protection Lawyer's Blog
A couple of months back, a patient with retinal artery occlusion ("RAO") was referred to Atlanta Hyperbaric for hyperbaric oxygen therapy ("HBOT") as her final hope to regain some vision. At that time, I discussed the available medical science in this blog. Recall that the best study was performed on a group of patients who received HBOT soon after the onset of RAO. My patient wasn't so lucky. Many weeks had elapsed between her episode of RAO and her referral to Atlanta Hyperbaric. I am pleased to report that after 18 hyperbaric treatments at 2.4 ATA for 90 minutes, she reports an improvement in visual acuity. I don't have all the data back from her ophthalmologist, and I am planning to continue her HBOT therapy, but I do have some impressive retinal scans. The first scan below shows what her retinas looked like at the beginning of her illness and several months before she was referred:. retinal-scan-1. ...

*  Intraocular Pressure During Prone Spinal Surgery - Full Text View - ClinicalTrials.gov
Postoperative permanent visual loss is a rare but devastating complication of surgery estimated to occur after approximately 1/60,000 anesthetics. After procedures involving cardiopulmonary bypass and prone spinal surgery, the estimates are higher, 1/1600 to 1/1100, respectively and have led to the formation in July of 1999 of the Postoperative Visual Loss (POVL) Registry under the auspices of the American Society of Anesthesia (ASA) Committee on Professional Liability. The majority of reported cases as of early 2003 were associated with spine surgery (67%).. Of the spine cases, the majority were due to ischemic optic neuropathy (ION) (81%) followed by central retinal artery occlusion (13%) and unknown diagnosis (6%). Central retinal artery occlusion is characterized by periorbital edema, a cherry red spot at the fovea and monocular blindness. It is thought to be due to ...

de Bruijne and colleagues (1) suggested an association between venous occlusion in the eye and elevated total plasma homocysteine levels. This association was established in an earlier study published in 1993 (2). In 19 patients who had retinal vein occlusion or retinal artery occlusion before 50 years of age, the incidence of hyperhomocysteinemia, as observed in heterozygosity for homocystinuria, was studied by the performance of a standardized, oral methionine-loading test. In 4 of the 19 patients (21%), 2 with retinal artery occlusion and 2 with central retinal vein occlusion, the afterload peak levels of homocysteine exceeded the mean level (established in normal controls) by more than 2 standard deviations and were well within the ...
