We studied various factors affecting the survival rate after vitreous surgery in 140 patients with diabetic retinopathy, who had undergone vitreous surgery between 1982 and 1990, according to the life-table theory and Cox proportional hazards model. The 5-year survival rate was 95.8%. The most common cause of death was cerebro-cardiovascular disease in 75.0%. The ratio of the observed number of deaths (O) to the expected ones (E), the O/E ratio, was significantly higher in patients who had undergone surgery between 55 and 69 years of age. The O/E ratio was significantly higher in both cardiovascular disease and cerebrovascular disease groups. Factors associated with a lower survival rate included age at operation, history of nephropathy, and neuropathy.
我们根据寿命表理论和Cox比例风险模型，研究了1982年至1990年间接受玻璃体手术的140例糖尿病视网膜病变患者玻璃体手术后影响生存率的各种因素。5年生存率为95.8%。最常见的死亡原因是心脑血管疾病，占75.0%。在55至69岁接受手术的患者中，观察到的死亡人数（O）与预期死亡人数（E）之比，即O/E比，显著更高。在心血管疾病和脑血管疾病组中，O/E比均显著更高。与较低生存率相关的因素包括手术年龄、肾病病史和神经病变。
