2/10. optic nerve lesion following neuroborreliosis: a case report.PURPOSE: Neuroborreliosis may cause various neuro-ophthalmological complications. We describe a case with a bilateral optic neuropathy. CASE REPORT: A 58-year-old female developed facial paresis six weeks after an insect bite. One week later she developed bilateral optic disc swelling with haemorrhages and nerve fibre bundle defects in the lower visual field of the left eye. In CSF and serum, raised IgM and IgG titres to borrelia burgdorferi were found. Systemic antibiotic treatment led to improvement of the vision and facial paresis, but not all visual field defects resolved, probably due to ischemic lesions of the optic disc. DISCUSSION/CONCLUSIONS: In optic nerve lesions due to neuroborreliosis it is difficult to distinguish between inflammatory and ischemic lesions. This patient demonstrated features of an ischemic optic nerve lesion.- - - - - - - - - - ranking = 0.003196365957724keywords = haemorrhage (Clic here for more details about this article) |
3/10. Retinal manifestations of ophthalmic artery hypoperfusion.ophthalmic artery hypoperfusion is a relatively uncommon clinical entity. This study illustrates the posterior segment findings of ophthalmic artery hypoperfusion in a series of nine patients. Colour photographs and relevant fluorescein angiograms highlighting the findings are shown. The retinal manifestations of ophthalmic artery hypoperfusion in this series of patients include midperipheral haemorrhages, dilated retinal veins, optic disk collaterals, optic disk neo-vascularization, cotton wool spots, grey intraretinal lesions, fundus pallor, optic disk swelling and choroidal infarcts. Recognition of the ophthalmic changes in this condition may lead to detection of carotid artery disease, the surgical and medical treatment of which has important bearing on patient management.- - - - - - - - - - ranking = 0.003196365957724keywords = haemorrhage (Clic here for more details about this article) |
4/10. arteriovenous malformations presenting with papilloedema.Cerebral arteriovenous malformations (AVMs) are fairly common and the majority of paediatric patients with this condition also present with intracranial haemorrhage. Two patients who had an incidental finding of an AVM associated with papilloedema are described here. The first was a 13-year-old male who presented after an accidental kick to the eyes. Examination revealed bilateral papilloedema. He gave a 2-year history of intermittent headache. brain magnetic resonance imaging (MRI) showed an unruptured AVM in the temporal lobe. Lumbar puncture revealed elevated cerebrospinal fluid pressure. visual acuity and visual fields were normal. He was treated with acetazolamide and improved within a few weeks. He subsequently underwent stereotactic radiosurgery to the AVM. He discontinued acetazolamide due to adverse side effects and there was no recurrence of headache and papilloedema. The second patient was a 14-year-old male who had polyarticular juvenile chronic arthritis and received low-dose steroids and methotrexate. Bilateral papilloedema was discovered during routine ophthalmology surveillance and he was otherwise asymptomatic neurologically. brain MRI revealed an AVM in the posterior fossa. He had three embolization procedures, which have resulted in significant reduction in lesion size. The papilloedema resolved completely after the first two procedures, and visual acuity and fields remained normal. Here, possible underlying mechanism of raised intracranial pressure and importance of visual assessment in those with AVMs and their management are discussed.- - - - - - - - - - ranking = 0.003196365957724keywords = haemorrhage (Clic here for more details about this article) |
5/10. Usefulness of post-mortem ophthalmological endoscopy during forensic autopsy: a case report.Post-mortem intraocular findings in two autopsy cases with traumatic intracranial haemorrhage were obtained using an ophthalmological endoscope. The endoscopy results clearly revealed the presence of intraocular haemorrhages and papilledema caused by intracranial haemorrhage. Post-mortem ophthalmological endoscopy offers several benefits. First, post-mortem intraocular findings can be directly observed in corpses with post-mortem clouding of the cornea. Secondly, the endoscopy only requires a 0.9 mm incision in the sclera and does not require the removal of the eye from the corpse, a procedure that should be avoided for ethical and cosmetic reasons. Thus, post-mortem opthalmological endoscopy is a useful method for obtaining intraocular findings in autopsies.- - - - - - - - - - ranking = 0.0095890978731721keywords = haemorrhage (Clic here for more details about this article) |
6/10. Combined central retinal artery and vein occlusion in churg-strauss syndrome: case report.PURPOSE: To describe a rare case of churg-strauss syndrome presenting with severe visual loss due to a combined central retinal vein and artery occlusion. methods: A 42-year old man with a medical history of asthma and blood hypereosinophilia developed a sudden loss of vision in his right eye. We describe the clinical features and evolution of the case after treatment. RESULTS: A combined occlusion of the central retinal artery and central retinal vein was diagnosed by the funduscopic appearance of retinal whitening, macular cherry-red spot, papilloedema, retinal haemorrhages in all four quadrants and dilated and tortuous veins. The diagnosis was confirmed by a fluorescein angiogram showing absence of retinal filling and normal choroidal filling. churg-strauss syndrome was diagnosed based on the necessary presence of four of six criteria for the disease proposed by the American College of rheumatology. Corticosteroid therapy was initiated. However, during the following year when tapering off the daily dosage, the patient experienced two relapses, with pulmonary symptoms and hypereosinophilia, and the corticosteroid dosage had to be augmented. The patient presented with neovascular glaucoma 7 weeks after the vascular occlusion and experienced no visual improvement. CONCLUSION: Combined central retinal artery and vein occlusion can occur in churg-strauss syndrome. We suggest that regional vasculitis may be the pathological mechanism underlying the vascular occlusions observed in our case. The condition carries a very poor prognosis for vision, due to the resulting retinal ischaemia, and a poor general prognosis due to the late stage of the systemic disease. Corticosteroids should be instigated promptly in order to prevent further systemic or ocular vasculitis.- - - - - - - - - - ranking = 0.24920090851057keywords = retinal haemorrhage, haemorrhage (Clic here for more details about this article) |
7/10. Retinal haemorrhages and papilloedema due to benign intracranial hypertension in a pregnant diabetic.A case of benign intracranial hypertension associated with generalized oedema is reported in a normotensive pregnant patient with long-standing insulin-treated diabetes mellitus. Following treatment with bed rest, chlorthalidone and dexamethasone the condition resolved and a healthy infant was delivered. This condition, not previously reported in a diabetic pregnancy, must be differentiated from other causes of bilateral optic nerve abnormalities associated with retinal haemorrhages and oedema, including diabetic retinopathy, diabetic optic neuropathy, accelerated hypertension and cerebral mass lesions. Treatment is required to prevent permanent visual impairment due to pressure on the susceptible optic nerve of the diabetic patient and to avoid the metabolic consequences to both mother and fetus of poor nutritional intake due to nausea.- - - - - - - - - - ranking = 0.26198637234147keywords = retinal haemorrhage, haemorrhage (Clic here for more details about this article) |
8/10. Macular changes resulting from papilloedema.Six cases are presented with macular changes in association with papilloedema; 4 suffered permanent visual loss. The present paper emphasises this previously infrequent finding and discusses the haemodynamic and mechanical factors responsible. The macular changes consisted of haemorrhages situated in front, within, or behind the retina, and occasionally the results of neovascular membrane formation produced secondary visual loss. Changes in the pigment epithelium were seen in 3 cases associated with choroidal folds. Macular stars rarely produce visual loss. Recognition of these changes is important in the assessment of the visual loss in papilloedema.- - - - - - - - - - ranking = 0.003196365957724keywords = haemorrhage (Clic here for more details about this article) |
9/10. Peripheral retinal haemorrhages with papilloedema.Two cases are described with severe intracranial hypertension, papilloedema, and a hitherto unreported haemorrhagic peripheral retinopathy. The marked disc swelling in these patients has probably contributed to a venous occlusive element resulting in the haemorrhagic retinopathy.- - - - - - - - - - ranking = 0.99680363404228keywords = retinal haemorrhage, haemorrhage (Clic here for more details about this article) |
10/10. Ischaemic optic neuropathy after spinal fusion.PURPOSE: We report a case of ischaemic optic neuropathy which occurred after prolonged spine surgery in the prone position in an obese, diabetic patient. CLINICAL FEATURES: The patient was a 44-yr-old, 123 kg, 183 cm man for decompressive laminectomy and instrumented fusion of the lumbar spine. Anaesthesia was induced with thiopentone, fentanyl and succinylcholine and maintained with nitrous oxide, oxygen, isoflurane and a fentanyl infusion. He was positioned prone on the Relton-Hall frame and had an uneventful intraoperative course. Estimated blood loss was 3,000 ml. He was taken to the surgical intensive care unit (SICU) and the trachea was extubated 3.5 hr later. He had no pulmonary or haemodynamic problems and went to a regular nursing floor in the morning. He was discharged home on postoperative day #5. He telephoned his surgeon on postoperative day #7 to say that his vision had been blurry since surgery. His visual acuity was decreased, and on examination, he had a bilateral papillary defect, optic swelling and a splinter haemorrhage in the right eye. magnetic resonance imaging (MRI) scan of the head and orbits detected no other abnormality. Based on this examination, he was felt to have bilateral ischaemic optic neuropathy and treated conservatively. By postoperative day #47, his visual acuity was greatly improved and near normal. Careful review of possible contributing factors suggests that the cause of the ischaemic optic neuropathy was venous engorgement. CONCLUSION: This patient developed ischaemic optic neuropathy from a prolonged interval in the prone position of the Relton-Hall frame, which may be related to venous engorgement.- - - - - - - - - - ranking = 0.003196365957724keywords = haemorrhage (Clic here for more details about this article) |
