11/19. blindness following fracture of the zygomatic bone.Two cases of blindness following fracture of a zygomatic bone, with disruption of the optic canal are reported. The importance of excluding optic canal disruption where blindness results subsequent to fracture or surgery to the orbit in the presence of certain features of retrobulbar haemorrhage is emphasised.- - - - - - - - - - ranking = 1keywords = haemorrhage (Clic here for more details about this article) |
12/19. Lumboperitoneal shunting as a cause of visual loss in benign intracranial hypertension.The causes of visual loss in benign intracranial hypertension are related to long standing papilloedema, ischaemic optic neuropathy or haemorrhage into a subretinal neovascular membrane. decompression procedures generally preserve or improve visual acuity but surgical treatment with subtemporal decompression may lead to visual impairment. Such a deficit has been recorded in the past as occurring with ventriculography. Postulated mechanisms have included brain herniation, spasm of vessels supplying the visual cortices or retinal vascular disturbance. To our knowledge treatment with lumboperitoneal shunting has not previously been reported as leading to further significant visual loss in this condition. This report describes such an occurrence in a patient. Retinal vascular disturbance is postulated on the basis of several normal CT scans, normal CSF pressure measured after surgery and visual evoked responses suggesting retinal or optic nerve damage.- - - - - - - - - - ranking = 1keywords = haemorrhage (Clic here for more details about this article) |
13/19. Ophthalmic manifestations of pituitary apoplexy.A case of pituitary apoplexy which occurred in a patient with prolactinoma is reported. The signs and symptoms on presentation were headache, loss of vision, sixth-nerve palsy, subarachnoid haemorrhage and fever. physicians are alerted to the necessity of prompt and accurate diagnosis in this condition to allow urgent decompression of the anterior visual pathways.- - - - - - - - - - ranking = 1keywords = haemorrhage (Clic here for more details about this article) |
14/19. Transient monocular obscuration--?amaurosis fugax: a case report.A 73-year-old white man with pseudophakia experienced repeated bouts of transient visual loss associated with erythropsia and colour desaturation. A diagnosis of atheromatous carotid vascular disease was considered, prompting carotid angiography, during which time the patient experienced transient aphasia. Subsequent examination during an episode of visual loss showed that a spontaneous anterior chamber haemorrhage was the cause of the visual complaints.- - - - - - - - - - ranking = 1keywords = haemorrhage (Clic here for more details about this article) |
15/19. Orbital haemorrhage and prolonged blindness: a treatable posterior optic neuropathy.Two patients developed traumatic orbital haemorrhage resulting in prolonged blindness. Orbital decompression successfully reversed the visual loss, though both eyes had no light perception for at least 3 1/2 hours. The clinical findings suggest damage to the posterior optic nerve as cause of the visual loss. The optic nerve tolerance time to ischaemic injury may be longer than previously thought.- - - - - - - - - - ranking = 5keywords = haemorrhage (Clic here for more details about this article) |
16/19. Retrobulbar haemorrhage: can blindness be prevented?Retrobulbar haemorrhage is a rare complication following orbital trauma or surgery occurring in less than 1 per cent of cases. early diagnosis and treatment of this complication may save the vision of the affected eye. This paper illustrates cases where diagnosis was not made and blindness resulted. We also present two cases of successful treatment due to early diagnosis.- - - - - - - - - - ranking = 5keywords = haemorrhage (Clic here for more details about this article) |
17/19. blindness after intranasal ethmoidectomy.Orbital haemorrhage is an unusual and frustrating complication of ethmoid surgery. A case of reversible blindness which was due to intra-operative orbital haemorrhage occurring after intranasal ethmoidectomy is presented. Prevention and management of this kind of blindness can be reversed, if treated aggressively.- - - - - - - - - - ranking = 2keywords = haemorrhage (Clic here for more details about this article) |
18/19. Irreversible blindness in systemic lupus erythematosis.We describe a patient with systemic lupus erythematosis and renal involvement and who developed visual impairment in the absence of hypertension and anti-cardiolipin antibodies. This was attributed to occlusive vascular disease and choroidal infarction in the context of active lupus. Complete and irreversible blindness developed rapidly despite treatment and the patient died of cerebral haemorrhage 2 months after discharge.- - - - - - - - - - ranking = 1keywords = haemorrhage (Clic here for more details about this article) |
19/19. Caesarean section following a recent retinal haemorrhage.We report a case of a 32-year-old woman who developed an antenatal Valsalva-induced retinal haemorrhage causing unilateral blindness 38 weeks into her pregnancy. Delivery was achieved by elective Caesarean section under epidural anaesthesia. The influence of anaesthetic technique on a recent retinal haemorrhage is discussed.- - - - - - - - - - ranking = 48.240474158858keywords = retinal haemorrhage, haemorrhage (Clic here for more details about this article) |
