Sharma S, Pater J, Lam M, cress A. - Arteriolosclerotic arteriole compressing venue --> capillary leakage thrombus at branched venue triangular with apex at A/V crossing majority are superior temporal more A/V crossings Superficial mostly NFL haemorrhages BRPO-20/200, extensive - almost an entire quadrant Ono APO - lead away from ischemic but APO - lead towards ischemic hard to tell with 20/200 vision BRVO-Macular enema is expected signs of ischema- cotton wool spots if C - it likely has a macular infarct BRVO-Good amount of blood in retina, cotton wool spots, hard to tell if it is ischemic or not -5DD or more of non-perfusion on an Angiogram = Ischemic BRVO-Large haemorrhage, macula is involved, C vision --> this is ischemic. Our pages on information for everyday living offer ideas for people with sight problems on making life easier and ways of getting the most out of life. RVO has been recognized as an entity since 1855, but many aspects of the pathogenesis and management of this disorder remain uncertain. Zegarra H, gunman FA, Conforto J: The natural course of central retinal vein occlusion. Most important fact is that a treatment which does not have a sound science to back up does not work in the long ladder, howsoever aggressively it may be advocated. Conclusion: Available evidence indicates that oral or intravitreal corticosteroids may help to reduce macular enema associated with non-ischemic CRVO and improve visual acuity in some patients, but only as long as they are on the treatment. In order to judge the appropriateness of this mode of treatment, one has to evaluate its benefits and risks from the available data.
Ophthalmic Les. 2008. 401:26-31. Are retinal haemorrhages evident? It is second only to diabetic retinopathy as a cause of visual loss due to retinal vascular disease. If you have a retinal vein occlusion your sight loss may be gradual, rather than sudden. Neovascularization of the retina or optic nerve may cause bleeding vitreous haemorrhage, and neovascularization of the iris may result in intractable glaucoma, which means high internal eye pressure that fails to respond to conventional therapy.
