In a series of 1000 patients examined consecutively in a large diabetic clinic, 95 (9.5%) were classified as having serious diabetic retinopathy. The definition was confined to exudative retinopathy (macular oedema or hard exudates encroaching upon the macula), proliferative retinopathy, and retinal ischaemia (as evidenced by the presence of soft exudates in the absence of hypertension, together with characteristic vascular changes). The diagnosis of serious diabetic retinopathy is always accompanied by a need for specialised ophthalmological assessment (including fluorescein angiography) and, often, urgent photocoagulation. Investigation and treatment are time-consuming, and such patients therefore constitute a major workload for the ophthalmological services: the average time for an ophthalmic consultation was found to be 20 min, and when fluorescein angiography was added to this the time increased to 40 min. The average time spent on photocoagulation for neovascularization was 2 h for each eye, and for exudative retinopathy 30 min for each eye.
在一家大型糖尿病诊所连续检查的1000例患者中，95例（9.5%）被归类为患有严重糖尿病视网膜病变。其定义限于渗出性视网膜病变（黄斑水肿或侵犯黄斑的硬性渗出物）、增殖性视网膜病变和视网膜缺血（在无高血压情况下出现软性渗出物以及特征性血管改变即可证明）。严重糖尿病视网膜病变的诊断总是伴随着需要进行专业眼科评估（包括荧光素血管造影），而且常常需要紧急进行光凝治疗。检查和治疗都很耗时，因此这类患者构成了眼科服务的主要工作量：眼科会诊的平均时间为20分钟，若加上荧光素血管造影，时间则增至40分钟。每只眼睛进行新生血管光凝治疗的平均时间为2小时，渗出性视网膜病变每只眼睛为30分钟。
