目的：了解糖尿病人和一般老年人白内障术后视力恢复程度及其与尿微蛋白系列的相互关系。方法：对近2年住院行白内障复明术的病人，顺序选糖尿病和无糖尿病的老年性白内障各50例，测定尿微蛋白系列和各项实验室检测作比较。结果：糖尿病组的尿微蛋白系列显著高于对照组。其中尿β2M高于正常上限者达50％；ALb82％；IgG52％。对照组分别是22％；14％；4％。P值＞0．01～0．001。是早期诊断糖尿病肾病的一个指标。结论：糖尿病视网膜病交往往合并糖尿病肾损害，早期DN的诊断不但能抓紧在DN的关键时期及时治疗，可望逆转DN进展．也有助于对这部分糖尿病白内障复明术的病员，加强随访观察和治疗，并可作为评定预后的指标。尿微蛋白系列强阳性者视力预后差，并发症多。
Objective: To understand the degree of visual acuity recovery after cataract surgery in diabetic patients and the elderly and its relationship with urinary micro-protein series. Methods: In the past two years, hospitalized patients with cataract surgery, the order of diabetes and non-diabetic senile cataract in 50 cases, urine microalbumin series and various laboratory tests for comparison. Results: Urinary micro-protein in diabetic group was significantly higher than that in control group. Urine β2M which is higher than the upper limit of up to 50%; ALb82%; IgG52%. Control groups were 22%; 14%; 4%. P value> 0.01 ~ 0.001. Is an indicator of early diagnosis of diabetic nephropathy. Conclusion: Diabetic retinopathy often associated with diabetic nephropathy, early diagnosis of DN can not only pay close attention to the timely treatment of DN in key periods, is expected to reverse the progress of DN. But also help to improve the follow-up observation and treatment of patients with this part of diabetic cataract patients and can be used as an index to evaluate the prognosis. Urine micro-protein series of strong positive eyesight poor prognosis, complications.
