目的：探讨糖尿病患者并发糖尿病视网膜病变（Ｄｉａｂｅｔｉｃｒｅｔｉｎｏｐａｔｈｙ，ＤＲ）对视功能的影响。方法：回顾性分析１３５例糖尿病患者的病史、性别、视力、眼底表现及眼底改变与视力的关系以及空腹血糖（ＦＢＧ）、餐后２小时血糖（ＰＢＧ）、糖基化血红旦白（ＨｂＡ１ｃ）等实验室指标。结果：ＤＲ患者的视功能下降较非ＤＲ患者重，随ＤＲ病程进展患者的视功能损害有逐渐加重的趋势，ＤＲ致盲的主要原因是玻璃体出血（占５０％）。ＤＲ患者的病程、ＨｂＡ１ｃ水平长于或高于非ＤＲ患者，女性糖尿病患者ＤＲ发生率高于男性。结论：ＤＲ对糖尿病患者视功能有严重影响，具较强的致盲性；糖尿病患者的病程、性别、血糖控制情况可作为预测ＤＲ发生的参考指标，利于糖尿病患者的视力保护。
Objective: To investigate the effect of diabetic retinopathy (Diabeticretinopathy, DR) on visual function. Methods: A retrospective analysis of 135 patients with diabetes mellitus history, gender, visual acuity, ocular fundus manifestations and the relationship between eyesight changes and visual acuity, fasting blood glucose (FBG), postprandial blood glucose 2 hours (PBG), glycosylated hemoglobin (HbA1c) Other laboratory indicators. Results: The decline of visual function in patients with DR was more severe than that in non-DR patients. The visual impairment of patients with DR was gradually aggravated. The main cause of DR blindness was vitreous hemorrhage (50%). The course of DR patients, HbA1c levels were longer or higher than non-DR patients, female patients with diabetes DR incidence was higher than men. Conclusion: DR has a serious effect on the visual function of diabetic patients and has a strong blinding effect. The course, sex and blood sugar control of diabetic patients can be used as a reference index to predict the occurrence of DR, which is beneficial to the eyesight protection of diabetic patients.
