目的观察中年糖尿病患者治疗前后屈光度的改变。方法对113眼糖尿病患者治疗前的屈光检查,通过内分泌科正规冶疗后再行屈光检查。结果经过半年的随访观察,大多数患者裸眼视力不及治疗前,治疗后二月内为远视状态,而治疗后三月远视度开始减退,近视度开始增加,治疗后半年基本回复原来近视状态。结论糖尿病屈光改变(糖尿病性屈光不正)与血糖波动有关,血糖高时,晶状体变凸,产生近视现象,反之血糖降低晶状体变扁平形成远视。
Objective To observe the changes of diopter in middle-aged diabetic patients before and after treatment. Methods 113 eyes of diabetic patients prior to treatment of refractive examination, after endocrine department of regular treatment before refraction. Results After six months of follow-up observation, the majority of patients with uncorrected visual acuity were less than those before treatment and two months after treatment. However, myopia began to decline in March after 3 months of treatment, myopia began to increase, and myopia returned to normal after 6 months of treatment. Conclusion Diabetic refractive changes (diabetic refractive error) and blood glucose fluctuations related to high blood sugar, the lens becomes convex, resulting in myopia, the other hand, blood sugar to reduce the formation of flat lens hyperopia.
