将230位行彩色眼底照相和眼底荧光血管造影检查的2型糖尿病患者,分为无视网膜病变(NDR)、非增殖型视网膜病变(NPDR)轻度、NPDR中度、NPDR重度和增殖型视网膜病变(PDR)五期。根据裂隙灯接触镜检查判断有无黄斑水肿。按较好眼视力情况分为≤0.1、≤0.5、≤1.0、>1.0四等级;按照视功能调查表(VFQ-25)修改版自我评分情况分为≤30分、≤40分、≤50分、≤60分、≤75分、>75分六等级。所得数据进行χ2检验。结果:诊断分期、黄斑水肿与视力、评分等级差异有非常显著性(P<0.01);NDR、轻度NPDR、中度NPDR(143例)与视力、评分等级差异无显著性(P>0.05)。结论:在DR发展的全过程中,病变的严重程度、有无黄斑水肿与视力变化以及自我感知有明显的相关性;而在病变的早期不相关。
230 patients with type 2 diabetes mellitus who underwent fundus photography and fundus fluorescein angiography were divided into three groups: non-retinopathy (NDR), nonproliferative retinopathy (NPDR) mild, NPDR moderate, NPDR severe and proliferative retinopathy (PDR) five issues. According to slit lamp contact lens examination to determine whether the macular edema. According to the situation of better visual acuity, it is divided into four grades of ≤0.1, ≤0.5, ≤1.0,> 1.0. According to VFQ-25, the self-assessment score is divided into ≤30 points, ≤40 points and ≤50 points , ≤ 60 points, ≤ 75 points,> 75 points six levels. The data obtained χ2 test. Results: There was a significant difference in diagnostic staging, macular edema, visual acuity and grading scale (P <0.01). There was no significant difference in visual acuity and grading between NDR, mild NPDR and moderate NPDR (P> 0.05) . Conclusion: The severity of the disease, the presence of macular edema, the change of visual acuity and self-perception are obviously related to the whole process of DR development, but not related to the early stages of the disease.
