The course of diabetic retinopathy following cataract extraction was studied retrospectively in 89 patients (89 eyes). Cataract extraction was extracapsular in 12 eyes (13.5%), extracapsular with intraocular lens implantation in 37 (41.6%), and intracapsular in 40 (45%). In 55 eyes (61.8%) there was no change in the retinal status after surgery, and in 34 (38.2%) there was progression of diabetic retinopathy. In the eyes showing progression there was appearance or aggravation of non-proliferative changes in 85.3% and development of proliferative diabetic retinopathy in 14.7%. Most of these eyes (91%) deteriorated within six months of surgery. Risk factors for the progression of diabetic retinopathy were the preoperative existence of diabetic retinopathy (p less than 0.005) and the need for antidiabetic agents in addition to dietary control in the management of diabetes (p less than 0.025).
对89例患者（89只眼）白内障摘除术后糖尿病视网膜病变的病程进行了回顾性研究。12只眼（13.5%）行囊外白内障摘除术，37只眼（41.6%）行囊外白内障摘除联合人工晶状体植入术，40只眼（45%）行囊内白内障摘除术。55只眼（61.8%）术后视网膜状态无变化，34只眼（38.2%）糖尿病视网膜病变进展。在病变进展的眼中，85.3%出现或加重了非增殖性改变，14.7%发生了增殖性糖尿病视网膜病变。这些眼中大部分（91%）在术后6个月内病情恶化。糖尿病视网膜病变进展的危险因素为术前存在糖尿病视网膜病变（p<0.005）以及糖尿病管理中除饮食控制外还需要抗糖尿病药物治疗（p<0.025）。
