糖尿病黄斑病变患者黄斑区背向散射积分值的测定

Scores measurement of macular region by integrated backscatter technique in diabetic maculopathy patiens

目的研究糖尿病黄斑病变患者黄斑区背向散射特性。方法选取糖尿病患者58例,分为无糖尿病性黄斑水肿(NDME)组25例和糖尿病性黄斑水肿(DME)组33例,另选健康对照(NC)组30名。采用HP Sonos5500超声诊断仪检测黄斑区背向散射积分(IBS)值。结果NC、NDME和DME组黄斑区IBS值、IBS%比较差异均有统计学意义[(43.41±2.37)vs(45.58±3.26)vs(47.65±1.47);(0.860±0.012)vs(0.940±0.009)vs(1.019±0.021),P<0.01]。结论糖尿病黄斑病变患者IBS值、IBS%较正常人群高,IBS技术可能是评价糖尿病黄斑病变的有效方法。

Objective To investigate the integrated backscatter （IBS） values of macular lutea in diabetic maculopathy, Methods 58 diabetes mellitus patients were divided into non-diabetic macular edema （NDME） group and diabetic macular edema （DME） group. 30 normal control （NC） people were as NC group. Their IBS values of maeular region were measured by HP Sonos5500., Results There was significant difference among three groups in IBS value and IBS% [（43.41±2.37） vs （45.58±3.26） vs （47. 65±1. 47） ; （0. 860±0. 012） vs （0.940±0.009） vs （1.019±0.021）,P〈0.01]. Conclusion IBS value and IBS% of diabetic maculopathy patients are increased as compared to those of NC people. IBS technique is useful method to assess diabetic maculopathy.
