Among 407 patients (416 eyes) with retinal vein occlusion (RVO), 196 eyes had branch RVO, 185 eyes central RVO, and 26 eyes hemi-central RVO. The ischemic type accounted for 39.7%, and the non-ischemic type 60.3%. The risk factors were vascular hypertension (59.8%), retinal arteriosclerosis (58.0%), increased blood beta-lipoprotein (49.0%) and fibrinogen (21.7%), and high blood viscosity. The mean levels of whole blood and plasma viscosity were significantly higher in the patients than in the controls. The therapeutic effective rate was 63.2% for branch RVO, 52.4% for central RVO, and 69.2% for hemicentral RVO. The resultant rate of blindness was 15.9%, and that of low vision 23.1%, due to cystoid macular edema (44.4%) and vitreous hemorrhage (15.4%). The incidence of neovascular glaucoma was 9.5% in central RVO.
在407例视网膜静脉阻塞（RVO）患者（416只眼）中，196只眼为分支视网膜静脉阻塞，185只眼为中央视网膜静脉阻塞，26只眼为半中央视网膜静脉阻塞。缺血型占39.7%，非缺血型占60.3%。危险因素包括血管性高血压（59.8%）、视网膜动脉硬化（58.0%）、血液β-脂蛋白升高（49.0%）和纤维蛋白原升高（21.7%）以及高血粘度。患者全血和血浆粘度的平均水平显著高于对照组。分支视网膜静脉阻塞的治疗有效率为63.2%，中央视网膜静脉阻塞为52.4%，半中央视网膜静脉阻塞为69.2%。由于黄斑囊样水肿（44.4%）和玻璃体积血（15.4%），失明发生率为15.9%，低视力发生率为23.1%。中央视网膜静脉阻塞中新血管性青光眼的发生率为9.5%。
