糖尿病患者泪膜功能的探讨

Tear Film Function in Non-insulin Dependent Diabetics.

目的 探讨糖尿病患者泪膜功能及其影响因素。方法 80例（160只眼）糖尿病病程5-10年的2型糖尿病患者；60例（120只眼）无糖尿病者设为对照组；观察角膜荧光素染色、泪膜破裂时间及Schimer试验。结果 糖尿病患者的泪膜功能较差，表现为泪膜稳定性下降，角膜荧光素染色。结论 糖尿病患者是干眼症的易患人群；糖尿病患者常规角膜荧光索染色检查有助于早期发现糖尿病引起的角膜病变。泪膜破裂时间、角膜荧光素染色检查可作为糖尿病患者的眼科常规检查。

Objective To investigate whether diabetes mellitus is correlated with tear film dysfuntion. Methods In 80 non-insulin dependent diabetic cases （160 eyes） and 60 non-dibetic controls, the tear break-up time was determined, Schimer test, fluorescien. Results When compared with the healthy control geoup,the diabetic group showed decreased tear film break up time, increased rate of staining with fluorescein sodium on the cornea and abnormal conjunctival epithelium. Conclusion Non-insulin dependent diabetics are correlated with tear film dysfunction, so they are susceptible persons of the dry eye. The tear film break up time andstaining with fluorescein sodium on the cornea should become routine tests of ophthalmology in diabetes mellitus.
