There were 8 patients with retinal vessel occlusion, 6 of which were complicated with lesion in central nerve system.

有8例视网膜血管阻塞的病人，其中6例出现中枢神经系统病变。

The incidence of the the batt-like exudation in retina were the highest(57.7%), followed by retinal vessel occlusion(46.2%).

本组病例中视网膜棉絮状渗出检出率最高（5 7.7% ） ，其次为视网膜血管阻塞（4 6 .2 % ）。

Conclusion The hemodynamic features of central retinal arteries in patients with retinal vein occlusion are low blood flow velocity, low vessel filling intensity and poor distal tissue blood filling.

结论视网膜静脉阻塞病人的视网膜中央动脉血流变化特点为血流速度、血管充盈强度减低，远端组织血流灌注不良。
