采用双侧颈总动脉阻断血流（２ＶＯ）的方法，造成大鼠不完全性视网膜缺血，用组织学方法观察了不同缺血时间（３０、９０ｍｉｎ，４、７、１４、３０ｄ）和缺血后再灌流与不再灌流对视网膜变化的影响。结果显示：缺血３０和９０ｍｉｎ再灌流４ｄ后，内视网膜（包括外网层、内核层、内网层、节细胞层、神经纤维层和内界膜）明显增厚；其他不再灌流的缺血组，厚度趋向减少。节细胞计数随缺血时间延长逐渐减少；缺血４ｄ后明显减少。提示不完全性视网膜缺血随时间延长引起视网膜病理损害。
Bilateral carotid artery occlusion of blood flow (2VO) method, resulting in incomplete retinal ischemia in rats, observed by histological different ischemic time (30,90min, 4,7,14,30 d) and Effect of reperfusion and no - reperfusion on the changes of retina after ischemia in. The results showed that the inner retina (including the outer layer, the inner layer, the inner layer, the cell layer, the nerve fiber layer and the inner limiting membrane) were significantly thicker at 4 and 4 days after reperfusion at 30 and 90 minutes, respectively. Blood group, the thickness tends to decrease. Cell counts gradually decreased with prolongation of ischemic time; decreased significantly after 4 days of ischemia. Suggestive incomplete retinal ischemia with retinal pathological damage caused by prolonged damage.
