Retinal vein occlusion is the most common retinal vascular disease after diabetic retinopathy. Because the retinal artery and vein share a common adventitial sheath, branch retinal vein occlusion almost always occurs at arteriovenous crossings. The exact pathogenesis of this disease remains unclear. A variety of systemic and ocular disorders associated retinal vein occlusion have been identified. Primary open angle glaucoma, hypertension, diabetes mellitus and arteriosclerosis are the most frequent disorders predisposing to retinal vein occlusion. The degree of visual loss is variable, due to macular edema or hemorrhage. Ocular neovascularization is one of the most serious complications of this disease. Fluorescein angiography are used to evaluate eyes with retinal vein occlusion. Currently, there is no effective treatment to prevent visual lost or retrieve lost vision after retinal vein occlusion. The best approach is investigation and treatment of disorders assosiated retinal vein occlusion to prevent the progression of disease from nonischemic to ischemic and to decrease the risk in the contralateral eye.Keywords: Retinal vein occlusion; central retinal vein occlusion; branch retinal vein occlusionTurkiye Klinikleri J Ophthalmol 2007, 16:56-66
