Amaurosis Fugax: Transient complete or partial monocular blindness due to retinal ischemia. This may be caused by emboli from the CAROTID ARTERY (usually in association with CAROTID STENOSIS) and other locations that enter the central RETINAL ARTERY. (From Adams et al., Principles of Neurology, 6th ed, p245)Blindness: The inability to see or the loss or absence of perception of visual stimuli. This condition may be the result of EYE DISEASES; OPTIC NERVE DISEASES; OPTIC CHIASM diseases; or BRAIN DISEASES affecting the VISUAL PATHWAYS or OCCIPITAL LOBE.Leber Congenital Amaurosis: A rare degenerative inherited eye disease that appears at birth or in the first few months of life that results in a loss of vision. Not to be confused with LEBER HEREDITARY OPTIC NEUROPATHY, the disease is thought to be caused by abnormal development of PHOTORECEPTOR CELLS in the RETINA, or by the extremely premature degeneration of retinal cells.Carotid Artery Diseases: Pathological conditions involving the CAROTID ARTERIES, including the common, internal, and external carotid arteries. ATHEROSCLEROSIS and TRAUMA are relatively frequent causes of carotid artery pathology.Ischemic Attack, Transient: Brief reversible episodes of focal, nonconvulsive ischemic dysfunction of the brain having a duration of less than 24 hours, and usually less than one hour, caused by transient thrombotic or embolic blood vessel occlusion or stenosis. Events may be classified by arterial distribution, temporal pattern, or etiology (e.g., embolic vs. thrombotic). (From Adams et al., Principles of Neurology, 6th ed, pp814-6)Retinal Artery Occlusion: Sudden ISCHEMIA in the RETINA due to blocked blood flow through the CENTRAL RETINAL ARTERY or its branches leading to sudden complete or partial loss of vision, respectively, in the eye.Carotid Artery, Internal: Branch of the common carotid artery which supplies the anterior part of the brain, the eye and its appendages, the forehead and nose.Carotid Stenosis: Narrowing or stricture of any part of the CAROTID ARTERIES, most often due to atherosclerotic plaque formation. Ulcerations may form in atherosclerotic plaques and induce THROMBUS formation. Platelet or cholesterol emboli may arise from stenotic carotid lesions and induce a TRANSIENT ISCHEMIC ATTACK; CEREBROVASCULAR ACCIDENT; or temporary blindness (AMAUROSIS FUGAX). (From Adams et al., Principles of Neurology, 6th ed, pp 822-3)Endarterectomy, Carotid: The excision of the thickened, atheromatous tunica intima of a carotid artery.cis-trans-Isomerases: Enzymes that catalyze the rearrangement of geometry about double bonds. EC 5.2.Endarterectomy: Surgical excision, performed under general anesthesia, of the atheromatous tunica intima of an artery. When reconstruction of an artery is performed as an endovascular procedure through a catheter, it is called ATHERECTOMY.Angiography: Radiography of blood vessels after injection of a contrast medium.Retinal Artery: Central retinal artery and its branches. It arises from the ophthalmic artery, pierces the optic nerve and runs through its center, enters the eye through the porus opticus and branches to supply the retina.Constriction, Pathologic: The condition of an anatomical structure's being constricted beyond normal dimensions.Remission, Spontaneous: A spontaneous diminution or abatement of a disease over time, without formal treatment.Optic Atrophy, Hereditary, Leber: A maternally linked genetic disorder that presents in mid-life as acute or subacute central vision loss leading to central scotoma and blindness. The disease has been associated with missense mutations in the mtDNA, in genes for Complex I, III, and IV polypeptides, that can act autonomously or in association with each other to cause the disease. (from Online Mendelian Inheritance in Man, http://www.ncbi.nlm.nih.gov/Omim/, MIM#535000 (April 17, 2001))Cerebrovascular Disorders: A spectrum of pathological conditions of impaired blood flow in the brain. They can involve vessels (ARTERIES or VEINS) in the CEREBRUM, the CEREBELLUM, and the BRAIN STEM. Major categories include INTRACRANIAL ARTERIOVENOUS MALFORMATIONS; BRAIN ISCHEMIA; CEREBRAL HEMORRHAGE; and others.Carotid Arteries: Either of the two principal arteries on both sides of the neck that supply blood to the head and neck; each divides into two branches, the internal carotid artery and the external carotid artery.Ultrasonography, Doppler, Duplex: Ultrasonography applying the Doppler effect combined with real-time imaging. The real-time image is created by rapid movement of the ultrasound beam. A powerful advantage of this technique is the ability to estimate the velocity of flow from the Doppler shift frequency.Eye ProteinsOptic Atrophies, Hereditary: Hereditary conditions that feature progressive visual loss in association with optic atrophy. Relatively common forms include autosomal dominant optic atrophy (OPTIC ATROPHY, AUTOSOMAL DOMINANT) and Leber hereditary optic atrophy (OPTIC ATROPHY, HEREDITARY, LEBER).Retinal Degeneration: A retrogressive pathological change in the retina, focal or generalized, caused by genetic defects, inflammation, trauma, vascular disease, or aging.

Through it, proteins synthesized in the inner segment are transported to the outer segment.Retinal Dystrophies: A group of disorders involving predominantly the posterior portion of the ocular fundus, due to degeneration in the sensory layer of the RETINA; RETINAL PIGMENT EPITHELIUM; BRUCH MEMBRANE; CHOROID; or a combination of these tissues.Retrospective Studies: Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.Electroretinography: Recording of electric potentials in the retina after stimulation by light.

Axillary-to-carotid artery bypass grafting for symptomatic severe common carotid artery occlusive disease. (1/38)

PURPOSE: Revascularization of the internal or external carotid arteries is occasionally indicated for symptomatic atherosclerotic common carotid artery occlusion or long-segment high-grade stenosis beginning at its origin. I report the outcome of axillary artery-based bypass grafts to the distal common, internal, or external carotid arteries. METHODS: Between 1981 and 1997, 29 axillary-to-carotid bypass grafting procedures were performed on 28 patients, 15 men and 13 women, with a mean age of 68 years. Indications were transient ischemia in nine patients, amaurosis fugax in four patients, completed stroke in six patients, and nonlateralizing global ischemia in nine patients. Twenty-three common carotid arteries were totally occluded, and six had long-segment stenosis of 90% or greater beginning at the origin. Saphenous vein grafts were used in 25 procedures, and synthetic grafts were used in four. Grafts were placed to 13 internal, eight distal common, and eight external carotid arteries. RESULTS: There were no perioperative deaths; one stroke occurred (3.4%). No lymphatic or peripheral nerve complications occurred. In a 1- to 11-year follow-up period (mean, 4.5 years), there were no graft occlusions, one restenosis of 50% or greater, and two restenoses of 70% or greater. The 1-year stenosis-free rate for 50% or greater stenosis was 93%, and the 5- and 10-year rates were 87%. No late ipsilateral strokes occurred. The 5- and 10-year survival rates were 64% and 28%, respectively. Coronary artery disease was the major cause of late mortality. CONCLUSION: Axillary-to-carotid bypass grafting for severe symptomatic common carotid occlusive disease is safe, well tolerated, durable, and effective in stroke prevention. There is a high late mortality rate because of coronary artery disease in patients with severe proximal common carotid occlusive disease.  (+info)

Hemispheric symptoms and carotid plaque echomorphology. (2/38)

PURPOSE: In patients with carotid bifurcation disease, the risk of stroke mainly depends on the severity of the stenosis, the presenting hemispheric symptom, and, as recently suggested, on plaque echodensity. We tested the hypothesis that asymptomatic carotid plaques and plaques of patients who present with different hemispheric symptoms are related to different plaque structure in terms of echodensity and the degree of stenosis. METHODS: Two hundred sixty-four patients with 295 carotid bifurcation plaques (146 symptomatic, 149 asymptomatic) causing more than 50% stenosis were examined with duplex scanning. Thirty-six plaques were associated with amaurosis fugax (AF), 68 plaques were associated with transient ischemic attacks (TIAs), and 42 plaques were associated with stroke. B-mode images were digitized and normalized using linear scaling and two reference points, blood and adventitia. The gray scale median (GSM) of blood was set to 0, and the GSM of the adventitia was set to 190 (gray scale range, black = 0; white = 255). The GSM of the plaque in the normalized image was used as the objective measurement of echodensity. RESULTS: The mean GSM and the mean degree of stenosis, with 95% confidence intervals, for plaques associated with hemispheric symptoms were 13.3 (10.6 to 16) and 80.5 (78.3 to 82.7), respectively; and for asymptomatic plaques, the mean GSM and the mean degree of stenosis were 30.5 (26.2 to 34.7) and 72. 2 (69.8 to 74.5), respectively. Furthermore, in plaques related to AF, the mean GSM and the mean degree of stenosis were 7.4 (1.9 to 12. 9) and 85.6 (82 to 89.2), respectively; in those related to TIA, the mean GSM and the mean degree of stenosis were 14.9 (11.2 to 18.6) and 79.3 (76.1 to 82.4), respectively; and in those related to stroke, the mean GSM and the mean degree of stenosis were 15.8 (10.2 to 21.3) and 78.1 (73.4 to 82.8), respectively. CONCLUSION: Plaques associated with hemispheric symptoms are more hypoechoic and more stenotic than those associated with no symptoms. Plaques associated with AF are more hypoechoic and more stenotic than those associated with TIA or stroke or those without symptoms. Plaques causing TIA and stroke have the same echodensity and the same degree of stenosis. These findings confirm previous suggestions that hypoechoic plaques are more likely to be symptomatic than hyperechoic ones. They support the hypothesis that the pathophysiologic mechanism for AF is different from that for TIA and stroke.  (+info)

Clinical and pathophysiological features of amaurosis fugax in Japanese stroke patients. (3/38)

OBJECTIVE: It has been emphasized that amaurosis fugax (AmF) is caused by thromboembolism due to atheromatous lesions of the extracranial carotid artery (EC-CA) in Caucasian populations. However, there have been few studies of AmF in Japan. We analyzed the clinical and pathophysiologic features of AmF in 43 Japanese AmF patients. SUBJECTS AND METHODS: Forty-three patients presented with AmF from a group of 2,056 Japanese patients with acute ischemic stroke. We investigated angiographic and transcranial Doppler findings, precipitating factors, medical treatment and prognosis, to elucidate the pathogenetic mechanism of AmF. RESULTS: Angiographic findings revealed an intracranial lesion in 22 patients (51%), extracranial lesion in 16 (37%), and no abnormality in 5 (12%). Blood flow in the ophthalmic artery (OA) examined by the transcranial Doppler ultrasonography (TCD) showed normal antegrade flow in 24 patients and reversed flow in 7. Precipitating factors for AmF were seen in 7 out of 43 patients. Regarding the pathogenesis of AmF, the micro-thromboembolism originated from the internal carotid artery (ICA) in 25 patients, the thromboembolism was via the external carotid artery (ECA) in 7, the hemodynamic retinal vascular insufficiency in 6 patients showed various atheromatous changes in the intracranial carotid artery (IC-CA) or EC-CA, and the cause was unknown in 5. CONCLUSION: In this series of patients, AmF was mainly caused by thromboembolism from IC-CA atheromatous lesions. Micro-thromboemboli from the ECA or hemodynamic retinal vascular insufficiency, although less frequent, should also be considered as possible etiologies for AmF.  (+info)

Echomorphologic and histopathologic characteristics of unstable carotid plaques. (4/38)

BACKGROUND AND PURPOSE: Our hypothesis was that the carotid plaques associated with retinal and cerebrovascular symptomatology and asymptomatic presentation may be differ from each other. The aim of this study was to identify the sonographic and histopathologic characteristics of plaques that corresponded to these three clinical manifestations. METHODS: The echo process involved duplex preoperative imaging of 71 plaques (67 patients, 21 plaques were associated with retinal, 25 with cerebrovascular symptoms, and 25 were asymptomatic), which was performed in a longitudinal fashion. Appropriate frames were captured and digitized via S-video signal in a computer and digitized sonograms were normalized by two echo-anatomic reference points: the gray scale median (GSM) of the blood and that of the adventitia. The GSM of the plaques was evaluated to distinguish dark (low-GSM) from bright (high-GSM) plaques. Subsequent to endarterectomy, the plaques were sectioned transversely, and a slice at the level of the largest plaque area was examined for the relative size of necrotic core and presence of calcification and hemorrhage. RESULTS: Retinal symptomatology was associated with a hypoechoic plaque appearance (median GSM: 0), asymptomatic status with a hyperechoic plaque appearance (median GSM: 34), and cerebrovascular symptomatology with an intermediate plaque appearance (median GSM: 16) (P = .001). The histopathologic characteristics did not disclose differences between the three clinical groups. The hypoechoic plaque appearance was associated only with the presence of hemorrhage (median GSM for the hemorrhagic plaques, 6, and for the non-hemorrhagic ones, 20 [P = .04]). The relative necrotic core size and the presence of calcification did not show any echomorphologic predilection. CONCLUSION: Our results showed that distinct echomorphologic characteristics of plaques were associated with retinal and cerebrovascular symptomatology and asymptomatic status. Histopathologically, only the presence of hemorrhage proved to have an echomorphologic predilection.  (+info)

Types of neurovascular symptoms and carotid plaque ultrasonic textural characteristics. (5/38)

The aim of this study was to identify the echo morphology and stenosis of carotid plaques that corresponded to ipsilateral asymptomatic status, amaurosis fugax, hemispheric transient ischemic attack, and stroke. One hundred ninety-two plaques (150 patients), producing stenosis in the range of 50% to 99% and associated with various neurovascular manifestations, were studied. These plaques were imaged on duplex scans, and a series of textural features was produced in a computer to distinguish quantitatively their various echo patterns. Amaurosis fugax corresponded to dark, severely stenosed atheromas (90%); hemispheric transient ischemic attack and stroke corresponded to plaques with intermediate echoic characteristics and intermediate stenosis (80%); and asymptomatic status corresponded to bright, moderately stenosed plaques (70%; P < .05). The significance of these findings is discussed.  (+info)

Delayed onset of amaurosis fugax in a patient with type A aortic dissection post surgical repair. (6/38)

Stroke is an important complication for the surgical treatment of type A aortic dissection and it occurs immediately post operation. Many surgical techniques such as deep hypothermic circulatory arrest and retrograde cerebral perfusion have been reported to ameliorate this complication. We report here a male Taiwanese patient with type A aortic dissection involving the arch who underwent surgical repair. Amaurosis fugax appeared on the 4th day post operation. Funduscopic findings demonstrated multi focal embolization and carotid sonography revealed normal carotid arteries. The symptoms and signs improved after anticoagulation therapy. This is a rare case of delayed onset of amaurosis fugax in a patient with type A aortic dissection post surgical repair. The thromboemboli might have originated from the internal surface of the sawing area.  (+info)

Reoperation for recurrent carotid stenosis: early results and late outcome in 199 patients. (7/38)

PURPOSE: This study was undertaken to determine the safety and efficacy of reoperations for recurrent carotid stenosis (REDOCEA) at the Cleveland Clinic. MATERIALS AND METHODS: From 1989 to 1999, 206 consecutive REDOCEAs were performed in 199 patients (131 men, 68 women) with a mean age of 68 years (median, 69 years; range, 47-86 years). A total of 119 procedures (57%) were performed for severe asymptomatic stenosis, 55 (27%) for hemispheric transient ischemic attacks or amaurosis fugax, 26 (13%) for prior stroke, and 6 (3%) for vertebrobasilar symptoms. Eleven REDOCEAs (5%) were combined with myocardial revascularization, and another 19 (9%) represented multiple carotid reoperations (17 second reoperations and 2 third reoperations). Three REDOCEAs (1%) were closed primarily, and nine (4%) required interposition grafts, whereas the remaining 194 (95%) were repaired with either vein patch angioplasty (139 [68%]) or synthetic patches (55 [27%]). Three patients (2%) were lost to follow-up, but late information was available for 196 patients (203 operations) at a mean interval of 4.3 years (median, 3.9 years; maximum, 10.2 years). RESULTS: Considering all 206 procedures, there were 7 early (< 30 days) postoperative neurologic events (3.4%), including 6 perioperative strokes (2.9%) and 1 occipital hemorrhage (0.5%) on the 12th postoperative day. Seventeen additional neurologic events occurred during the late follow-up period, consisting of eight strokes (3.9%) and nine transient ischemic attacks (4.4 %). With the Kaplan-Meier method, the estimated 5-year freedom from stroke was 92% (95% CI, 88%-96%). There were two early postoperative deaths (1%), both from cardiac complications after REDOCEAs combined with myocardial revascularization procedures. With the Kaplan-Meier method, the estimated 5-year survival was 81% (range, 75%-88%). A univariate Cox regression model yielded the presence of coronary artery disease as the only variable that was significantly associated with survival (P =.024). The presence of pulmonary disease (P =.036), diabetes (P =.01), and advancing age (P =.006) was found to be significantly associated with stroke after REDOCEA. Causes of 53 late deaths were cardiovascular problems in 25 patients (47%), unknown in 14 (26%), renal failure in 4 (8%), stroke in 3 (6%), and miscellaneous in 7 (13%). CONCLUSIONS: We conclude that REDOCEA may be safely performed in selected patients with recurrent carotid stenosis and that most of these patients enjoy long-term freedom from stroke.  (+info)

Clinical features of transient monocular blindness and the likelihood of atherosclerotic lesions of the internal carotid artery. (8/38)

To assess which features of transient monocular blindness (TMB) are associated with atherosclerotic changes in the ipsilateral internal carotid artery (ICA), 337 patients with sudden, transient monocular loss of vision were prospectively studied. History characteristics of the attack were compared with the presence of atherosclerotic lesions of the ipsilateral ICA. All patients were directly interviewed by a single investigator. Of all patients, 159 had a normal ICA on the relevant side, 33 had a stenosis between 0%-69%, 100 had a stenosis of 70%-99%, and 45 had an ICA occlusion. An altitudinal onset or disappearance of symptoms was associated with atherosclerotic lesions of the ipsilateral ICA. A severe (70%-99%) stenosis was also associated with a duration between 1 and 10 minutes, and with a speed of onset in seconds. An ICA occlusion was associated with attacks being provoked by bright light, an altitudinal onset, and the occurrence of more than 10 attacks. Patients who could not remember details about the mode of onset, disappearance, or duration of the attack were likely to have a normal ICA. Our findings may facilitate the clinical decision whether or not to perform ancillary investigations in these patients.  (+info)

We present a consensus on the pathophysiology, etiology, diagnosis, and treatment of amaurosis fugax. The phenomenon is defined and described, and the roles that extracranial and ocular vascular diseases play are discussed. Nonvascular ophthalmic and neurologic disorders that can be confused with amaurosis fugax are listed, and an algorithm for evaluation (which includes ophthalmic examination, laboratory studies, and noninvasive carotid artery studies) is given. Treatment of atherosclerosis, carotid artery disease, and other causes of amaurosis fugax are also discussed. ...
Despite the temporary nature of the vision loss, those experiencing amaurosis fugax are usually advised to consult a physician immediately as it is a symptom that usually heralds serious vascular events, including stroke.[46][47] Restated, "because of the brief interval between the transient event and a stroke or blindness from temporal arteritis, the workup for transient monocular blindness should be undertaken without delay." If the patient has no history of giant cell arteritis, the probability of vision preservation is high; however, the chance of a stroke reaches that for a hemispheric TIA. Therefore, investigation of cardiac disease is justified.[3]. A diagnostic evaluation should begin with the patients history, followed by a physical exam, with particular importance being paid to the ophthalmic examination with regards to signs of ocular ischemia. When investigating amaurosis fugax, an ophthalmologic consult is absolutely warranted if available. Several concomitant laboratory tests ...
A prospective study of amaurosis fugax was carried out in a Danish community (population 481,000); case ascertainment was based on the collaboration of practicing ophthalmologists and general practitioners. Over a 3-year period we registered 131 cases; the annual incidence of "first amaurosis fugax episodes coming to medical attention" was 8.6 and 6.2 per 100,000 population for men and women, respectively. On the basis of a comparison of the age-incidence curves for cerebral and retinal ischemic attacks, the "true" incidence of amaurosis fugax is estimated to be approximately 14/100,000/yr, or 25-30% of the reported incidence of transient ischemic attacks. Clinical and/or radiologic signs of a carotid lesion on the appropriate side were present in 56% of the patients, and an additional 27% had symptoms or signs of other organic cardiovascular disorders. Forty-three (68%) of the 63 patients who underwent arteriography had an atheromatous lesion apparently amenable to carotid endarterectomy. In ...

Amaurosis fugax (Latin fugax meaning fleeting, Greek amaurosis meaning darkening, dark, or obscure) is a painless temporary loss of vision in one or both eyes. The experience of amaurosis fugax is classically described as a temporary loss of vision in one or both eyes that appears as a black "curtain coming down vertically into the field of vision in one eye;" however, this altitudinal visual loss is relatively uncommon. In one study, only 23.8 percent of patients with transient monocular vision loss experienced the classic "curtain" or "shade" descending over their vision. Other descriptions of this experience include a monocular blindness, dimming, fogging, or blurring. Total or sectorial vision loss typically lasts only a few seconds, but may last minutes or even hours. Duration depends on the cause of the vision loss. Obscured vision due to papilledema may last only seconds, while a severely atherosclerotic carotid artery may be associated with a duration of one to ten minutes. Certainly, ...
Previous research has shown that early monocular blindness from unilateral enucleation (surgical removal of one eye) results in equivalent or enhanced form perception but impairments in aspects of motion processing (see Steeves et al., 2008). To further investigate the effects of early monocular blindness on form and motion processing, we compared binocularly and monocularly viewing controls to individuals who were unilaterally enucleated within the first few years of life. Thresholds were measured on three tasks that had not before been tested in this population; 1) contrast discrimination, 2) horizontal speed discrimination, and 3) horizontal coherent motion discrimination. Preliminary data are consistent with previous research showing early monocular blindness results in equivalent or enhanced sensitivity compared to binocularly and monocularly viewing controls at some contrasts. It also results in higher motion discrimination thresholds for lower speeds and a nasalward bias in the perception ...

Amaurosis fugax is a symptom of carotid artery disease. It occurs when a piece of plaque in a carotid artery breaks off and travels to the retinal artery in the eye. The carotid arteries provide the main blood supply to the brain. They are located on each side of your neck under the jaw. Plaque is a hard substance that forms when fat, cholesterol, and other substances build up in the walls of arteries. Pieces of plaque can block blood flow. In people with amaurosis fugax, vision loss continues as long as the blood supply to the retinal artery is blocked. Atherosclerosis of the arteries in the neck is the main risk factor for this condition. Risk factors for atherosclerosis include heart disease, high cholesterol, smoking, diabetes, and high blood pressure. ...
He also performed the pilgrimage to Mecca and Medina and also visited Jerusalem.[1] Saadi traveled through war wrecked regions from 1271 to 1294. Due to Mongol invasions he lived in desolate areas and met caravans fearing for their lives on once lively silk trade routes. Saadi lived in isolated refugee camps where he met bandits, Imams, men who formerly owned great wealth or commanded armies, intellectuals, and ordinary people. While Mongol and European sources (such as Marco Polo) gravitated to the potentates and courtly life of Ilkhanate rule, Saadi mingled with the ordinary survivors of the war-torn region. He sat in remote teahouses late into the night and exchanged views with merchants, farmers, preachers, wayfarers, thieves, and Sufi mendicants. For twenty years or more, he continued the same schedule of preaching, advising, and learning, honing his sermons to reflect the wisdom and foibles of his people. Saadis works reflects upon the lives of ordinary Iranians suffering displacement, ...

The extracranial venous system is complex and variable between individuals. Until recently, these variations were acknowledged as developmental variants and were not considered pathological findings. However, in the last decade, the presence and severity of uni- or bi-lateral jugular venous reflux have been linked to several central nervous system (CNS) disorders such as transient global amnesia, transient monocular blindness, cough headache, primary exertional headache and most recently to Alzheimers disease. The most recent introduction of a composite criteria-based vascular condition named chronic cerebrospinal venous insufficiency (CCSVI) that was originally linked to multiple sclerosis increased the interest in better understanding of the role of the extracranial venous system in the pathophysiology of CNS disorders. The ultimate cause-consequence relationship between these conditions and CNS disorders has not been firmly established and further research is needed. This article collection ...
We report 13 cases of ophthalmic complications resulting from dengue infection in Singapore. We performed a retrospective analysis of a series of 13 patients with dengue fever who had visual impairment. Investigations included Humphrey automated visual field analyzer, Amsler charting, fundus fluorescein angiography, and optical coherence tomography. Twenty-two eyes of 13 patients were affected. The mean age of patients was 31.7 years. Visual acuity varied from 20/25 to counting fingers only. Twelve patients (92.3%) noted central vision impairment. Onset of visual impairment coincided with the nadir of serum thrombocytopenia. Ophthalmologic findings include macular edema and blot hemorrhages (10), cotton wool spots (1), retinal vasculitis (4), exudative retinal detachment (2), and anterior uveitis (1). All patients recovered visual acuity to 20/30 or better with residual central scotoma by 12 weeks. These new complications suggest a widening spectrum of ophthalmic complications in dengue infection.

TMB Membrane Peroxidase Substrate (3, 3, 5, 5 - Tetramethylbenzidine) is a chromogenic substrate used to visualize antibody reactivity in ELISA experiments. In the presence of peroxidases, TMB can act as an electron donor for the conversion of peroxides to water, changing the color of solution to a blue color equivalent to the degree of reactivity. This reaction of TMB can be halted with acid to change the TMB to yellow. TMB Membrane Peroxidase Substrate (3, 3, 5, 5 - Tetramethylbenzidine) is ideal for investigators in Immunology, Cancer, and Microbiology research.

Ischemic stroke and intracranial artery disease demonstrate different characteristics depending on the race and region of the patient population. Intracranial atherosclerosis causes ,10% of ischemic strokes in white North American patients [13,14], but causes 50%-60% of strokes in Asian populations [15,16]. Hispanic and black patients demonstrate a relative rate of intracranial atherosclerosis-related strokes that is five times greater than that of white patients [17]. Hence, the most common cause of ischemic stroke worldwide could be intracranial atherosclerosis [16]. Atherosclerosis results from a cascade of endothelial dysfunction processes, infiltration of modified lipids into the intima, and vascular wall inflammation or remodeling [18]. On HR-MRI, atherosclerotic plaques, lipid cores, fibrous components, hemorrhage, and calcium are the most important components [6]. In the cervical carotid arteries, it may be easier to characterize the vascular wall, to differentiate these components, and ...

Three cases of intractable spontaneous posterior epistaxis refractory to nasal packing and complicated by ipsilateral carotid artery occlusive disease were successfully treated with internal maxillary artery occlusion with microcoils. There were no complications and no recurrent episodes of epistaxis at a mean follow-up of 12 months. The presence of ipsilateral carotid artery disease requires modification of standard distal internal maxillary artery embolization because of the recruitment of external carotid to internal carotid and external carotid to ophthalmic artery collateral pathways, with subsequent risk of particle embolization of these arterial distributions. Proximal internal maxillary artery microcoil embolization eliminates this risk and is equivalent to surgical internal maxillary artery ligation. This procedure also provides additional information about the internal carotid artery collateral circulation.. ...

PD-L1 expression, for all its value to date in helping filter appropriate patient populations, has limitations. Studies have shown higher levels are correlated with improved response rates. Yet, some patients with high scores still dont respond to treatment, and others with lower levels do. Additionally, there are no standard assays to test PD-L1 levels, making it difficult to compare across clinical trials. Tumour mutational burden (TMB) is a quantitative clinical marker that measures the number of mutations within a tumour genome. TMB has been found to be an indicator of likelihood of progression-free survival (PFS) benefit from immunotherapies when used alone (monotherapy) in patients with non-small cell lung cancer (NSCLC).. Roche hopes that measuring TMB could help solve some of these problems and potentially replace, or at least be complementary to, testing for PD-L1 expression.. "Foundation Medicine has previously shown that measuring tumor mutational burden from tissue samples can help ...

While it is widely accepted that GPCRs regulate ERKs (Post and Brown, 1996), the pathways used are not always defined and may vary between cell types or even receptor subtypes (Post and Brown, 1996; van Biesen et al., 1996). Our studies demonstrate the following in rat liver epithelial cells: first, Ang II can stimulate ERK via two independent pathways, a putative Ras/Raf‐independent, PKC‐dependent pathway in naive GN4 cells and a Ras/Raf‐dependent pathway observed when PKC activation is prevented. Secondly, the latter pathway may involve adaptor protein tyrosine phosphorylation as exemplified by Cbl and Shc (Figure 4). Tyrosine phosphorylation of these proteins is only seen in the absence of PKC activity. Thirdly, the Ang II, Ras‐dependent pathway in PKC‐depleted cells appears to involve the EGF receptor. Ang II stimulated EGF receptor and Cbl tyrosine phosphorylation in PKC‐depleted GN4 cells (Figure 7); both these effects were abolished by selective EGF receptor tyrosine kinase ...
Carotid atherosclerosis is a pathological thickening of the common or internal carotid intima, typically into focal areas known as plaques (or atheromata). Although atheromata can remain stable for many years, surface rupture of unstable (vulnerable) plaques leads to local thrombus formation, with subsequent embolisation to the ipsilateral ophthalmic, middle cerebral, or anterior cerebral artery territories. The resultant symptoms are ipsilateral amaurosis fugax or retinal infarction and contralateral body transient ischaemic attack (TIA) or stroke. This review discusses the risk factors, clinical presentation, investigations, and treatment options for symptomatic and asymptomatic carotid atherosclerosis.

The patient presented with a 2-month history of worsening ataxia. Examination suggested the ataxia was cerebellar in origin with both midline and bilateral hemispheric symptoms suggesting that there was not a focal lesion, but rather diffuse involvement. The causes of a chronic/subacute onset of cerebellar ataxia are numerous. They can be simply divided into hereditary and sporadic, with sporadic further divided into symptomatic or idiopathic 2. The age of onset and lack of family history make hereditary causes unlikely although do not completely rule them out. Seventy-five percent of male carriers of the FRM1 premutation gene (full mutation form leads to fragile-X-associated tremor ataxia syndrome, an X-linked disorder) over the age of 80 will have ataxia. The carrier frequency of this premutation is relatively high (1:810 males) and studies of sporadic cerebellar ataxia in older males the prevalence of FMR1 premutation has been seen to be as high as 5%. Sporadic mutations also cannot be ...
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 direct prolonged extraocular pressure on the globe and thus is preventable. Direct pressure on the eye is the etiology most ...
Object. The purpose of this study was to determine whether the preoperative measurement of acetazolamide-induced changes in cerebral blood flow (CBF), which is performed using single-photon emission computerized tomography (SPECT) scanning, can be used to identify patients at risk for hyperperfusion following carotid endarterectomy (CEA). In addition, the authors investigated whether monitoring of CBF with SPECT scanning after CEA can be used to identify patients at risk for hyperperfusion syndrome.. Methods. Cerebral blood flow and cerebrovascular reactivity (CVR) to acetazolamide were measured before CEA in 51 patients with ipsilateral internal carotid artery stenosis (≥ 70% stenosis). Cerebral blood flow was also measured immediately after CEA and on the 3rd postoperative day.. Hyperperfusion (an increase in CBF of ≥ 100% compared with preoperative values) was observed immediately after CEA in eight of 12 patients with reduced preoperative CVR. Reduced preoperative CVR was the only ...
To characterize the severe postoperative irreversible visual loss induced by optic neuropathy in some children with a brain tumor, the computerized database (2003-2008) of a neuro-ophthalmology service of a major pediatric tertiary center was reviewed for all children with severe irreversible visual loss (counting fingers or less) due to brain-tumor-related optic neuropathy at their last follow-up examination. Data on age, gender, etiology, initial symptoms and signs, visual acuity before and after surgery and at last exam, neuroimaging findings, and treatment were collected. Of 240 children, 198 were operated. Of those, 10 (5%, 5 boys and 5 girls) met the study criteria. Data for the initial visual examination were available for 8 children: one had binocular blindness (uncertain light perception, counting fingers); 3 had monocular blindness already at diagnosis (no light perception, counting fingers, no fixation); 3 had 6/60 vision in the worse eye; and one had good vision bilaterally (6/10).

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 occlusion or branch retinal artery occlusion) leads to rapid death of retinal cells, thereby resulting in severe loss of vision. Those with ocular ischemic syndrome are typically between the ages of 50 and ...

Methods: In 16 patients, coronary artery calcification was assessed twice within 4 weeks by helical computed tomography. As part of a randomised controlled trial, patients received atorvastatin 80 mg daily or matching placebo, and had coronary calcification assessed annually. Fifty patients with previous coronary artery bypass surgery who were listed for diagnostic coronary angiography underwent contrast enhanced computed tomography angiography using a 16-slice computed tomography scanner. Finally, 15 patients with recent symptoms and signs of an acute transient ischaemic attack, amaurosis fugax or stroke underwent magnetic resonance angiography of the carotid arteries using dedicated surface coils. Results: Quantification of coronary artery calcification demonstrated good reproducibility in patients with scores ,100 AU. Despite reducing systemic inflammation and halving serum low-density lipoprotein cholesterol concentrations, atorvastatin therapy did not affect the rate of progression of ...

Carotid endarterectomy reduced death and strokes in patients with ipsilateral high-grade stenosis and recent hemispheric transient ischemic attacks or nondisabling strokes. The ECST and the NASCET are landmark studies. Many clinicians believed that persons with cerebral ischemic symptoms associated with high-grade carotid stenosis benefited from carotid endarterectomy. However, considerable doubt arose about a net benefit to society, given the high risk of surgery reported from some communities and the reported high frequency of inappropriate indications for carotid endarterectomy. These studies do not completely allay the doubt. In both studies the surgeons were carefully chosen and demonstrated lower perioperative morbidity and mortality than shown in community surveys. The major surprise in these studies is the high risk for stroke in the patients who did not have surgery; 22% in 3 years in ECST and 28% in 2 years in NASCET. The apparently higher risk in NASCET may be at least partly an ...

This study shows that a dedicated custom-made software tool can reproducibly quantify intracranial internal carotid artery calcifications. Furthermore, it shows that the presence of intracranial calcifications is associated with smoking, hypercholesterolemia, and history of cardiac disease and that the severity of calcifications is related to a history of cardiac disease and a history of ischemic cerebrovascular disease.. No difference was found in the volume of intracranial calcifications between the symptomatic and asymptomatic internal carotid arteries and in the volume of intracranial calcifications in the symptomatic artery between patients with amaurosis fugax and those with TIA or minor stroke.. Previous studies8-12 had a binary or a qualitative (5-point scale) grading system for classification of intracranial calcifications, probably because quantification difficulties arose due to the close relationship between calcifications and the bony structures of the skull.

Since 2012*. About QR-110. QR-110 is a first-in-class investigational RNA-based oligonucleotide designed to address the underlying cause of Lebers congenital amaurosis Type 10 due to the p.Cys998X mutation in the CEP290 gene. The p.Cys998X mutation is a substitution of one nucleotide in the pre-mRNA that leads to aberrant splicing of the mRNA and non-functional CEP290 protein. QR-110 is designed to restore wild-type CEP290 mRNA leading to the production of wild-type CEP290 protein by binding to the mutated location in the pre-mRNA causing normal splicing of the pre-mRNA. QR-110 is intended to be administered through intravitreal injections in the eye and has been granted orphan drug designation in the United States and the European Union..

The retina is the part of your eye that senses light so you can see. Retinal artery occlusion is a blood clot in an artery in the retina.. When an artery in the retina is blocked, doctors say it is "occluded." This blockage stops blood from flowing through the artery. And that can damage nerve cells that help you see.
