视网膜中央静脉阻塞目前公认的分类有两型,即①缺血性,②非缺血性。前者亦称视网膜中央血管闭塞,因出血多,视障重,预后恶,故又名出血性视网膜病变,其阻塞多系完全的。后者因系单纯的仅只是静脉阻塞,故又称静脉郁滞性视网膜病变,多系不完全性阻塞,或代偿性侧枝循环良好,症征轻而预后好,且年青人又多因系静脉炎导致者,故消炎疗法,特别是肾上腺皮质激素的早期大量全身使用,疗效颇佳。不过后者有可能向前者过渡,当然也可能这种向前者过渡的后者,本来就是前者的早期阶段。
Currently there are two types of central retinal vein occlusion recognized, namely ① ischemic, ② non-ischemic. The former also known as central retinal vascular occlusion, due to bleeding, visual impairment, the prognosis is evil, it is also known as hemorrhagic retinopathy, the blockage of more than complete. The latter simply because of the Department of vein obstruction, it is also known as venous stasis retinopathy, and more incomplete Department of obstruction, or compensatory collateral circulation is good, mild symptoms and good prognosis, and the young and more due to the Department Phlebitis leading to, therefore, anti-inflammatory therapy, especially the adrenal cortex hormones a large number of early systemic use, the effect is quite good. However, the latter may make the transition to the former, but it is also possible that such a transition to the former would have been the early stage of the former.
