摘要
目的 观察糖尿病视网膜病变(DR)患者黄斑部脉络膜厚度改变。方法 临床检查确诊的DR患者33例43只眼纳入研究。其中,男性16例20只眼,女性17例23只眼。根据裂隙灯显微镜联合90D前置镜、光相干断层扫描(OCT)检查结果,并依照DR国际分期标准,将患眼分为非增生型DR(NPDR)不伴显著性黄斑囊样水肿(CSME)(NPDR CSME-)组、NPDR伴CSME(NPDR CSME+)组,分别为16、27只眼。选取同期年龄>45岁健康志愿者和血压控制良好且眼底检查正常的高血压患者11例11只眼作为对照组。三组受检者间性别、年龄、眼别、等效球镜度数比较,差异均无统计学意义(χ^2=0.562, F=0.580, χ^2=0.129, F=0.421;P值均>0.05)。采用Topcon 3D OCT-1000仪分别测量各组黄斑中心凹下(C 0.0 mm),通过黄斑中心凹的水平方向距黄斑中心凹鼻侧(N)、颞侧(T)各500、1000、1500、2000、2500 μm处共11个位点的脉络膜厚度,以及黄斑中心凹视网膜厚度。结果 NPDR CSME+组C 0.0 mm、T 0.5 mm、T 1.0 mm、T 1.5 mm、T 2.0 mm、T2.5 mm、N0.5 mm、N 1.5 mm位点脉络膜厚度较对照组变薄,差异有统计学意义(F=3.459、4.605、5.997、9.096、9.777、11.563、3.765、3.339,P<0.05);N1.0 mm、N 2.0 mm、N 2.5 mm位点脉络膜厚度亦较对照组变薄,但差异无统计学意义(F=2.889、3.157、2.194, P>0.05)。NPDR CSME-组各位点脉络膜厚度与对照组各位点脉络膜厚度比较,差异均无统计学意义(F=2.194、3.157、3.339、2.889、3.765、3.459、4.605、5.997、9.096、9.777、11.563,P>0.05)。NPDR CSME+组T2.5 mm、T 2.0 mm、T1.5 mm位点脉络膜厚度与NPDR CSME-组相同位点脉络膜厚度比较,差异有统计学意义(F=11.563、9.777、9.096,P<0.05);两组其余各位点脉络膜厚度比较,差异均无统计学意义(F=2.194、3.157、3.339、2.889、3.765、3.459、4.605、5.997, P>0.05)。相关性分析结果显示,对照组(r=-0.096)、NPDR CSME-组(r=0.026)、NPDR CSME+组(r=-0.067)黄斑中心凹下处脉络膜厚度与黄斑中心凹视网膜厚度无相关(P>0.05)。结论 NPDR黄斑水肿患者黄斑部脉络膜厚度较正常人变薄。
Objective To analyze the choroidal thickness (CT) in patients of diabetic retinopathy (DR). Methods A total of 33 DR patients (43 eyes) were enrolled in this study, including 16 males (20 eyes) and 17 females (23 eyes). They were divided non-proliferative diabetic retinopathy (NPDR) without macular edema (ME) group (NPDR CSME- group, 16 eyes), and NPDR with ME group (NPDR CSME+ group, 27 eyes) in accordance with international DR staging standard. The control group included healthy volunteers (age〉45 years) and hypertension patients with wellcontrolled blood pressure and normal fundus, totally 11 subjects (11 eyes). There was no significant difference between these 3 groups for gender, age, laterality, spherical equivalent degrees (χ^2=0.562, F=0.580, χ^2=0.129, F=0.421;P〉0.05). The CT and foveal retinal thickness were measured by Topcon 3D optical coherence tomography (OCT)1000 at 11 locations, including subfoveal, 5 locations (500, 1000, 1500, 2000, 2500 μm from the foveal) at the nasal or temporal side horizontally. Results The CT was significant thinner for NPDR CSME+ group than control group at 8 locations (subfoveal, T 0.5 mm, T 1.0 mm, T 1.5 mm, T 2.0 mm, T 2.5 mm, N 0.5 mm, N 1.5 mm) (F=3.459, 4.605, 5.997, 9.096, 9.777, 11.563, 3.765, 3.339;P〈0.05), but not at the other 3 locations (N1.0 mm, N2.0 mm N 2.5 mm)(F=2.889, 3.157, 2.194; P〉0.05). The CT was the same between NPDR CSME- group and control group (F=2.194, 3.157, 3.339, 2.889, 3.765, 3.459, 4.605, 5.997, 9.096, 9.777, 11.563;P〉0.05 ) . The CT was significant different (F=11.563, 9.777, 9.096;P〈0.05) between NPDR CSME- group and NPDR CSME+ group at 3 locations (T2.5 mm, T2.0 mm, T1.5 mm), but not other locations (F=2.194, 3.157, 3.339, 2.889, 3.765, 3.459, 4.605, 5.997; P〉0.05). Correlation analysis showed that in the control group (r=-0.096), NPDR CSME- group (r=0.026) and NPDR CSME+ group (r=-0.067) subfoveal CT and foveal retinal thickness was not correlated (P〉0.05). Conclusion NPDR macular edema patients have a thinner macular CT than control.
