We reviewed the records of 160 patients who had central retinal vein occlusion between 1980 and 1985. Of 168 eyes, 107 (64%) were classified as nonischemic types and 61 (36%) were classified as ischemic types. Of 107 nonischemic eyes, ten (9%) converted to the ischemic variant. Of 107 nonischemic eyes, 33 (31%) lost three or more lines of visual acuity irrespective of initial visual acuity. A final visual acuity less than or equal to 20/200 was recorded in 57 of 61 (93%) of ischemic eyes and 53 of 107 (50%) of nonischemic eyes.
我们回顾了1980年至1985年间160例视网膜中央静脉阻塞患者的病历。在168只眼中，107只（64%）被归类为非缺血型，61只（36%）被归类为缺血型。在107只非缺血眼中，有10只（9%）转变为缺血型。在107只非缺血眼中，33只（31%）无论初始视力如何，视力下降了三行或更多。61只缺血眼中有57只（93%）以及107只非缺血眼中有53只（50%）的最终视力记录小于或等于20/200。
