目的研究2型糖尿病视网膜病变(DR)患者维生素D的水平。方法选取健康体检者40例,2型糖尿病(T2DM)患者无眼底病变者40例,2型DR者40例,3组患者均测定维生素D水平。结果 3组间维生素D分布差异有显著性(P<0.05)。健康体检组与T2DM组及2型DR组维生素D水平比较差异有显著性(P<0.05),而T2DM组与2型DR组维生素D水平比较差异无显著性(P>0.05)。结论 T2DM患者及2型DR维生素D水平较正常人降低,2型DR患者更为明显。
Objective To investigate the level of vitamin D in type 2 diabetic retinopathy (DR). Methods Forty patients with healthy subjects, 40 patients with type 2 diabetes mellitus (T2DM) without fundus lesions, 40 patients with type 2 DR and 3 patients with vitamin D were measured. Results There were significant differences in the distribution of vitamin D between the three groups (P <0.05). There were significant differences in vitamin D levels between T2DM group and T2DM group and DR group (P <0.05), but there was no significant difference between T2DM group and DR group (P> 0.05). Conclusion The levels of vitamin D in type 2 diabetic patients and type 2 DR patients are lower than those in normal subjects, while type 2 DR patients are more obvious.
