１２２例（２４４只眼）检眼镜下未查见视网膜病变的Ⅱ型糖尿病患者，眼底荧光血管造影发现有病变者６６例（１３２只眼）．包括毛细血管荧光素渗漏、毛细血管扩张、微血管瘤、黄斑及视网膜水肿和毛细血管闭塞。采用多因素逐步回归法对早期糖尿病视网膜病变与全身因素的关系进行分析。结果表明：与空腹血糖、甘油三脂、病程和眼灌注压呈显著正相关，与眼压、发病年龄呈显著负相关。
122 patients (244 eyes) underwent ophthalmoscopy without retinopathy in patients with type Ⅱ diabetes, fundus fluorescein angiography found lesions in 66 cases (132 eyes). Including capillary fluorescein leakage, telangiectasia, microvascular tumors, macular and retinal edema, and capillary occlusion. The relationship between early diabetic retinopathy and systemic factors was analyzed by multivariate stepwise regression. The results showed that: with fasting blood glucose, triglycerides, duration and ocular perfusion pressure was significantly positive correlation, and intraocular pressure, onset age was significantly negatively correlated.
