摘　　要：目的探讨老年人非外伤性玻璃体大量积血的病因。方法对非外伤性玻璃体大量积血的老年患者81例83只眼的病因资料进行总结分析。结果81例中,视网膜静脉阻塞导致玻璃体大量积血的患者最多,33例(40.7%);其次,为增殖型糖尿病性视网膜病变患者31例(38.3%);渗出型老年性黄斑变性患者10例(12.4%)。视网膜静脉阻塞患者中,玻璃体大量积血迟发于视网膜静脉阻塞的时间间隔≥3个月为21只眼(63.6%),眼底检查均发现新生血管;<3个月者为9只眼(27.3%),眼底检查未发现新生血管。结论视网膜静脉阻塞、增殖型糖尿病性视网膜病变和渗出型老年性黄斑变性是老年人非外伤性玻璃体大量积血的主要病因。眼底新生血管的形成、破裂和出血是老年人非外伤性玻璃体大量积血的主要原因。Objective lo investigate the etiology of non-wounaea severe vitreous hemorrhage. in elderly patients Methods Eighty-three eyes of 81 elderly patients with non-wounded severe vitreous hemorrhage were studied for the etiological analysis. Results Of all the causes, retinal vein occlusion was the principal cause （40.7%）, the second was proliferative diabetic retinopathy （38.3%）, the third was exudative age-related macular degeneration （12.4%）. In the retinal vein occlusion group, the onset interval between retinal vein occlusion and severe vitreous hemorrhage was three months or more in 21 eyes （63.6 %） with fundus neovascularization, and less than three months in 9 eyes （27.3%） without fundus neovascularization. Conclusions Retinal vein occlusion, proli{erative diabetic retinopathy and exudative age-related maeular degeneration are the main causes of non-wounded severe vitreous hemorrhage in the elderly patients, among which the fundus neovascular forming, cracking and bleeding is the main cause.
