1/5. Diffuse retinal hemorrhages (ocular decompression syndrome) after trabeculectomy with mitomycin C for neovascular glaucoma.PURPOSE: To describe a case of ocular decompression syndrome in a patient after trabeculectomy with mitomycin C for neovascular glaucoma. RESULTS: Diffuse retinal hemorrhages developed in the posterior pole of a patient with neovascular glaucoma after he underwent trabeculectomy with mitomycin C. The hemorrhages persisted for less than 9 months. CONCLUSIONS: Acute decompression of the eye in patients with high intraocular pressure can lead to the development of posterior pole hemorrhages. The course of this rare syndrome is relatively benign.- - - - - - - - - - ranking = 1keywords = syndrome (Clic here for more details about this article) |
2/5. 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 = 1.1666666666667keywords = syndrome (Clic here for more details about this article) |
3/5. The dural shunt syndrome. I. Management of glaucoma.The authors present four cases of the dural shunt syndrome in which shallowing of the anterior chamber or rubeosis developed. All patients were female, ranging in age from 66 to 79 years, exhibiting elevated intraocular pressure (IOP), decreased extraocular movements, injected tortuous episcleral vessels, and proptosis. The authors managed these four cases with laser iridotomy, gonioplasty, panretinal photocoagulation, or medical treatment. It is important to recognize associated findings in patients with shallow anterior chambers and elevated IOPs so that a diagnosis of a dural shunt is considered and appropriately treated. Theories on the mechanisms of increased IOP in the dural shunt syndrome and the management of various types of glaucoma in four different cases are reviewed.- - - - - - - - - - ranking = 1keywords = syndrome (Clic here for more details about this article) |
4/5. Chronic ocular ischemia and neovascular glaucoma: a result of extracranial carotid artery disease.Severe occlusive disease of the carotid artery may produce a rare syndrome of chronic ocular ischemia. Prolonged retinal hypoxia is associated with characteristic funduscopic changes and neovascularization of the iris, with subsequent obstruction of aqueous humor resorption. A case of neovascular glaucoma as a result of severe bilateral carotid occlusive disease and the pathophysiology involved are discussed. Definitive treatment consisted of carotid endarterectomy and aggressive control of intraocular pressure, including operative placement of a drainage implant in the anterior chamber of the eye. Seizure activity and an exacerbation of glaucoma developed after successful revascularization, exemplifying the derangements in cerebral and ocular function that may result from chronic hypoperfusion.- - - - - - - - - - ranking = 0.16666666666667keywords = syndrome (Clic here for more details about this article) |
5/5. Pseudo-Brown's syndrome as a complication of glaucoma drainage implant surgery.Two cases of pseudo-Brown's syndrome occurring after superior nasal implantation of glaucoma filtering devices are described. We hypothesize that this restriction in ocular motility was due to the mechanical effects of large filtering blebs or increased inflammation and scar formation in the superior nasal quadrant. Serial ultrasound examinations of our patients demonstrated development of a large bleb, coincidental with the disturbance in motility. Because of the risk of strabismus, we no longer recommend placing large implant devices in the superior nasal quadrant in eyes that have good vision.- - - - - - - - - - ranking = 0.83333333333333keywords = syndrome (Clic here for more details about this article) |
