1/225. bartonella henselae infection associated with peripapillary angioma, branch retinal artery occlusion, and severe vision loss.PURPOSE: To report atypical clinical features of bartonella henselae neuroretinitis treated with combination antibiotics. METHOD: Case report. RESULTS: A 20-year-old man with a positive B. henselae titer developed a unilateral neuroretinitis, a large peripapillary angiomatous lesion, branch artery occlusion with ischemic maculopathy, and vision loss that failed to improve with clindamycin. Treatment with doxycycline and rifampin led to rapid clinical improvement. The severe vision loss in this case is atypical. CONCLUSIONS: Ocular findings associated with B. henselae infection may include retinal angiomatous lesion and branch retinal artery occlusion. doxycycline and rifampin were successful in treating the infection.- - - - - - - - - - ranking = 1keywords = artery (Clic here for more details about this article) |
2/225. Subdural empyema and blindness due to cavernous sinus thrombosis in acute frontal sinusitis.In this era of antibiotics, the complications of acute sinusitis are much less frequently encountered. Although orbital complications are most common, intracranial complications carry a high rate of mortality and morbidity. We describe a case of acute frontal sinusitis with subdural empyema and blindness due to cavernous sinus thrombosis and carotid artery thrombosis with a discussion of treatment of these complications and the etiology of blindness in sinusitis.- - - - - - - - - - ranking = 4.4837598049573keywords = carotid, carotid artery, artery (Clic here for more details about this article) |
3/225. Superselective intraarterial fibrinolysis in central retinal artery occlusion.Intraarterial fibrinolysis was performed in three patients with acute central retinal artery occlusion using recombinant tissue plasminogen activator as a fibrinolytic agent. In two cases the ophthalmic artery was selectively catheterized, and in the other a thrombolytic drug was infused into the ophthalmic artery by way of the meningeal collaterals. All patients experienced visual improvement. fibrinolysis can produce better results than obtained from conservative treatment. A good prognosis can be achieved if the treatment starts within the first 4 to 5 hours after occlusion.- - - - - - - - - - ranking = 1.1666666666667keywords = artery (Clic here for more details about this article) |
4/225. Branch retinal artery occlusion in systemic diseases: a case report.Although branch retinal artery occlusion (BRAO) is a relatively benign disease in terms of permanent visual impairment, the associated systemic diseases confer significant morbidity and mortality. The following systemic disorders can be found among patients presenting with a retinal artery occlusion: hypertension (59%), significant atherosclerotic cardiovascular disease (21%), diabetes mellitus (15% to 21%), left-sided valvular heart disease (5%), and cerebrovascular accidents (5%). These underlying systemic diseases are often responsible for a significant reduction in life expectancy and are in many cases potentially treatable conditions. A thorough cardiovascular examination (including a carotid duplex ultrasonography) may identify these occult diseases, and a prompt and effective treatment may improve the quantity and quality of patients' lives by reducing the risk of further arterial occlusive events.- - - - - - - - - - ranking = 3.5061029635keywords = carotid, artery (Clic here for more details about this article) |
5/225. Postprandial transient visual loss.BACKGROUND: Temporary loss of vision after ingestion of a large meal is a phenomenon that has been reported in only a small number of cases in the ophthalmic literature. CASE REPORT: A 60-year-old man reported episodes of blurred vision associated with visual aberrations in his left eye for 5 minutes after eating large meals. His medical history was significant for carotid artery disease, hypertension, "diet-controlled" diabetes, and hypercholesterolemia. The patient's symptoms abated when he ate in smaller quantities and was placed on a regimen of IOP-lowering eye drops. CONCLUSIONS: Postprandial transient visual loss can occur when blood gets shunted to the mesenteric system after eating, leaving the eye hypoperfused. It most commonly takes place in individuals whose ocular perfusion is already compromised by carotid disease, in combination with other vascular conditions that result in the inability to compensate for decreased perfusion to the eye. The signs and symptoms of postprandial visual loss--as well as the mechanisms thought to contribute to it--are discussed.- - - - - - - - - - ranking = 6.9898627684573keywords = carotid, carotid artery, artery (Clic here for more details about this article) |
6/225. Combined central retinal artery and vein occlusion in a child with systemic non-Hodgkin's lymphoma.PURPOSE: To report on a case of systemic non-Hodgkin's lymphoma and unilateral combined central retinal artery and vein occlusion. METHOD: We examined a 14-year-old boy who experienced a sudden unilateral visual loss five months after the initial diagnosis of systemic non-Hodgkin's lymphoma. RESULT: Visual loss was due to combined central retinal artery and vein occlusion in association with tumoral optic nerve involvement. CONCLUSION: Although very rare systemic non-Hodgkin's lymphoma may present with central retinal artery and vein occlusion prior to overt central nervous system involvement.- - - - - - - - - - ranking = 1.1666666666667keywords = artery (Clic here for more details about this article) |
7/225. alagille syndrome with cavernous carotid artery aneurysm.We present a case of right sided blindness caused by a cavernous carotid artery aneurysm in a 17-year-old patient presenting with an alagille syndrome. The diagnosis was made by magnetic resonance imaging and confirmed by angiography. This aneurysm was treated successfully with endovascular placement of detachable balloons. Cerebral vascular malformations are rarely reported in association with this syndrome. We discuss the clinical presentation, diagnosis, treatment and detection of this type of abnormality.- - - - - - - - - - ranking = 22.418799024787keywords = carotid, carotid artery, artery (Clic here for more details about this article) |
8/225. Traumatic carotid artery dissection causing blindness.A case of delayed postoperative visual loss due to bilateral traumatic carotid artery dissection is presented. In patients with a major craniofacial injury due to a high-speed motor vehicle accident, we suggest that carotid artery duplex ultrasonography be used in the initial evaluation for possible carotid artery dissection. magnetic resonance imaging of the head and neck with magnetic resonance angiography should be performed subsequently if indicated. early diagnosis and initiation of therapy can minimize complications.- - - - - - - - - - ranking = 31.386318634701keywords = carotid, carotid artery, artery (Clic here for more details about this article) |
9/225. A case of subarachnoid hemorrhage presenting with temporary blindness disclosed by Xe CT-CBF study.A 69-year-old male with right oculomotor palsy caused by non-ruptured right internal carotid-posterior communicating artery aneurysm suddenly became blind after cerebral angiography. He lost consensual response of left eye, in spite of no preretinal hemorrhage. xenon computed tomography(Xe-CT) showed moderate cerebral blood flow(CBF) decrease of bilateral posterior cerebral artery territories at the values of 26.9 ml/100 g/min(left) and 28.3 ml/100 g/min(right), which were about 30% under our control value. However, MR T2-weighted imaging demonstrated no cerebral infarction. Two weeks later, regional CBF values were improved and 6 months later his visual acuity were almost cured. We conclude that Xe-CT CBF study supports the hypothesis of the temporary blindness due to the optic chiasm and nerves injuries by subarachnoid hemorrhage.- - - - - - - - - - ranking = 2.8394362968333keywords = carotid, artery (Clic here for more details about this article) |
10/225. Central retinal vein occlusion combined with cilioretinal artery occlusion.A healthy 65-year-old man with sudden profound visual loss in his right eye presented with clinical signs of central retinal venous occlusion and retinal whitening, indicative of a cilioretinal arterial obstruction. He had been diagnosed with cilioretinal artery occlusion at a private ophthalmology clinic three days before being referred to our department. On fluorescein angiogram of the affected eye, the proximal portion of the retinal arteries filled with dye 27.3 seconds after injection, indicating a delay in retinal arterial filling. Moreover, the cilioretinal artery did not fill at that phase, but went on to fill 45.1 seconds after injection. Over 63.4 seconds after the filling of the retinal arteries, the laminar flow of the retinal venous vessels appeared. This was not until 90.7 seconds after injection. This patient was elderly, had no systemic diseases, and showed non-ischemic CRVO, prolonged retinal arterial filling on fluorescein angiography, and poor prognosis in visual acuity. His clinical course seemed to favor the pathogenetic hypothesis of a primary arterial affection.- - - - - - - - - - ranking = 1keywords = artery (Clic here for more details about this article) |
