【Abstract】 The clinical observation of 28 cases of central retinal vein occlusion showed that these cases were divided clearly into two independant types: venous stasis retinopathy (VSR) and retinopathy hemmorhagic (HR). VSR is caused simply by retinal vein occlusion and not associated with retinal ischemia. In these patients, there is always a better prognosis unless the macular oedema occurs persistently, so it is a benign selflimited disease.In HR, the ischemic changes were developed in capillaries and arterioles, so their prognosis is bad. With regard to treatment, if macular oedema occurred, the eye with VSR should be treated by steroids and if no macular oedema presented, the eye should not be given any therapy. But in HR, the purpose of treatment is to improve microcirculation of retina and to destroy microaneurysms, new vessels and the large avascular areas on fundus with laser photocoagulation.更多还原
