1/127. Cilioretinal artery occlusion during coronary catheterization.PURPOSE: To report on a patient with cilioretinal artery occlusion during cardiac catheterization. methods: A 51-year-old man complained of blurred vision in the left eye immediately following cardiac catheterization. visual acuity was 6/12 and the eye had a dense central scotoma. RESULTS: Mild retinal whitening of the posterior pole and segmented filling of the cilio-retinal artery established the diagnosis of cilioretinal artery occlusion. Immediate paracentesis was performed. Two weeks later, a tiny central scotoma could be observed and visual acuity was 6/6. CONCLUSIONS: cardiac catheterization may result in retinal infarction. awareness to any visual symptoms, immediate diagnosis and prompt intervention may prevent permanent visual impairment.- - - - - - - - - - ranking = 1keywords = eye (Clic here for more details about this article) |
2/127. Multiple retinal arteriolar occlusions associated with coexisting primary antiphospholipid syndrome and factor v Leiden mutation.PURPOSE: To investigate a case of a young woman with both primary antiphospholipid syndrome and factor v Leiden mutation who developed multiple retinal arteriolar occlusions. METHOD: Case report of a 25-year-old woman with history and laboratory tests confirming the diagnosis of both primary antiphospholipid syndrome and factor v Leiden mutation who presented with blurred vision in both eyes. RESULTS: Multiple retinal arteriolar occlusions were observed in both of her eyes. The patient was treated first with heparin and then with warfarin. CONCLUSIONS: Primary antiphospholipid syndrome and factor v Leiden mutation, as well as other forms of thrombophilia, should be considered in the differential diagnosis of unexplained retinal vascular occlusions. The coexistence of several thrombophilic disorders may carry a particularly high risk for thrombotic manifestations.- - - - - - - - - - ranking = 1keywords = eye (Clic here for more details about this article) |
3/127. 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 = eye (Clic here for more details about this article) |
4/127. Arteriovenous communication in the orbit.arteriovenous malformations (AVMs) are anomalous communications between arterial and venous systems without interposed capillaries. These lesions are rarely entirely intraorbital. A case of an arteriovenous communication between branches of the internal and external carotid arterial circulations and the ophthalmic veins located within the orbit is reported. Treatment with embolization resulted in a branch retinal artery occlusion. Attempted direct arterial occlusion of a dural-based fistula of the eye is a risky procedure. If embolized, AVMs should probably be approached from the venous side, if at all.- - - - - - - - - - ranking = 0.5keywords = eye (Clic here for more details about this article) |
5/127. Ocular massage in a case of central retinal artery occlusion the successful treatment of a hitherto undescribed type of embolism.BACKGROUND: The pathogenesis of central retinal artery occlusions (CRAO) varies, depending upon the underlying disease. An embolic origin of an occlusion often occurs. PATIENT AND methods: A 50-year-old man with an occlusion of the left internal carotid artery was examined because of a left central retinal artery occlusion. fluorescein angiography revealed that in no blood vessel could any circulation of blood be demonstrated. The slight vascular filling with dye mainly came from collateral circulation at the disc. RESULTS: Ocular massage was carried out. After a delay of several minutes, the vessels of the fundus became increasingly filled with blood. The patient noticed continuing recovery in the vision of his left eye. During fluorescein angiography, carried out one day later, white embolic clots appeared in the arteries of the papilla, some of them moving with the velocity of the blood flow through the retinal vessels and reaching the periphery of the retina and immediately disappearing. Others moved more slowly. This was seen repeatedly over several minutes. CONCLUSIONS: In this patient we have recorded in a fluorescein angiogram bright boluses visible in the blood of the retinal arteries. We suggest that conglomerations of blood cells can also cause an obstruction of blood flow. The observation of this kind of bright clots (boluses) visible in the blood of the retinal arteries we did not find described in the literature. In such a situation ocular massage is extremely helpful. Therefore, ocular massage should be carried out in every patient with CRAO.- - - - - - - - - - ranking = 0.5keywords = eye (Clic here for more details about this article) |
6/127. Spontaneous central retinal artery occlusion in hemoglobin sickle cell disease.PURPOSE: To describe a case of spontaneous central retinal artery occlusion in a young man with hemoglobin sickle cell disease. METHOD: Case report. RESULTS: A 31-year-old African-American man with a history of hemoglobin sickle cell disease developed sudden painless loss of vision in the right eye. Medical history was remarkable for the recent history of a mild painful crisis, but no other systemic illness or contributing factors. Central retinal artery occlusion was diagnosed with retinal whitening, cherry red spot, and delayed arteriovenous transit on fluorescein angiography. Over the ensuing week, the patient had visual recovery to 20/60 in the absence of therapeutic intervention. CONCLUSION: Central retinal artery occlusion has been reported in sickle cell hemoglobinopathies (ie, SS, S-thal, sickle trait, and sickle cell), but the association with sickle cell disease is rare. Most reports have described additional contributing factors, such as trauma or concomitant systemic illness, to help account for the central retinal artery occlusion. The present case suggests that sickle cell disease alone is sufficient for the development of central retinal artery occlusion.- - - - - - - - - - ranking = 0.5keywords = eye (Clic here for more details about this article) |
7/127. Branch retinal artery occlusion after thyroid artery interventional embolization.PURPOSE: To report a case of branch retinal artery occlusion after thyroid artery interventional embolization. methods: A 33-year-old man with hyperthyroidism complained of visual loss and scotoma in the left eye after thyroid artery interventional embolization. He underwent a full ophthalmologic examination, including fluorescein angiography. RESULTS: visual acuity was 20/25, with inferior and superior scotomas present in the left eye. fluorescein angiography of the left eye revealed delayed filling of a superotemporal branch retinal artery and nonfilling of an inferotemporal branch retinal artery. CONCLUSION: A small, but definite risk of retinal artery occlusion after thyroid artery interventional embolization should be considered.- - - - - - - - - - ranking = 1.5keywords = eye (Clic here for more details about this article) |
8/127. Occlusions of branch retinal arterioles following amniotic fluid embolism.amniotic fluid embolism is a serious complication of pregnancy with a high mortality. We present a 28-year-old healthy woman who underwent dilatation and curettage for an elective abortion, followed by the sudden loss of vision in her left eye. Occlusion of one branch retinal arteriole was the initial finding of her left fundus, and two occlusions developed consecutively on the color fundus photographs. fluorescein angiography demonstrated occlusions in three retinal arterioles among seven retinal arterioles originating from the optic disc. These findings suggest that possible mechanisms of amniotic fluid embolism are the unusual cause in retinal arteriolar occlusions. Here clinical course and ophthalmic findings are reviewed, and the relationship between amniotic fluid embolism and retinal arteriolar occlusions is discussed.- - - - - - - - - - ranking = 0.5keywords = eye (Clic here for more details about this article) |
9/127. Unilateral blindness as a complication of intraoperative positioning for cervical spinal surgery.The authors report a case of unilateral blindness after surgical vertebral stabilization for C5-C6 subluxation. The blindness resulted from ischemia of the retina caused by prolonged compression of the eyeball on the surgical bed. This injury can be serious and irreversible, so it must be prevented by placing the patient in the proper position. The anesthetist must pay particular attention to avoid the consequences of possible intraoperative movement.- - - - - - - - - - ranking = 0.5keywords = eye (Clic here for more details about this article) |
10/127. Maculo-papillary branch retinal artery occlusions following the Wada test.BACKGROUND: The Wada test induces short-term anesthesia of one hemisphere by injection of sodium amytal into an internal carotid artery. It is an important presurgical diagnostic tool in epileptic patients. PATIENT: A 22-year-old man with idiopathic epilepsy noticed a shadow in the central visual field of his right eye immediately following a Wada test of the right hemisphere. RESULTS: The patient presented with an occlusion of two small branch retinal arteries and corresponding defects in his visual field. fluorescence angiography revealed small dense hyperfluorescent spots within the occluded retinal vessels. CONCLUSION: Branch retinal artery occlusions are a possible complication of the Wada test, possibly induced by undissolved contrast medium or sodium amytal.- - - - - - - - - - ranking = 0.5keywords = eye (Clic here for more details about this article) |
