摘要:
目的 探讨糖尿病黄斑水肿患者在光学相干断层扫描(optical coherence tomography,OCT)中四个量化指标的变化。方法 纳入糖尿病视网膜病变患者89例(155眼),按照有无黄斑水肿分为阳性组(33例55眼)及阴性组(56例100眼),另收集正常志愿者23例(42眼)为正常对照组。所有试验对象经OCT检查,测量并分析各组黄斑中心凹视网膜厚度(central retinal thickness,CRT)、黄斑中心凹下脉络膜厚度(subfoveal choroidal thickness,SFCT)的差异,观察各组黄斑区外界膜(external limiting membrane,ELM)、椭圆体带(inner segment/outer segment,IS/OS)的连续性。结果 正常对照组、阴性组、阳性组CRT分别为(219.048±16.798)μm、(217.775±26.866)μm、(280.418±74.187)μm,3组间差异有统计学意义(P<0.001);3组SFCT分别为(312.893±140.559)μm、(302.080±125.287)μm、(293.745±140.517)μm,3组间差异无统计学意义(P=0.781);阴性组中黄斑区ELM连续97眼、中断3眼,阳性组连续47眼、中断8眼,两组间ELM连续性差异有统计学意义(P=0.019);阴性组中黄斑区IS/OS连续95眼、中断5眼,阳性组连续36眼、中断19眼,两组间IS/OS连续性差异有统计学意义(P<0.001)。结论 糖尿病黄斑水肿患者CRT增加,黄斑区ELM、IS/OS连续性遭到破坏,CRT、ELM连续性及IS/OS连续性可用于量化评估糖尿病黄斑水肿。
Abstract:
Objective To observe the changes of four quantitative indexes of diabetic macular edema by using optical coherence tomography.Methods Eighty-nine patients (155 eyes) with diabetic retinopathy were included in this project and were divided into two groups according to the present of diabetic macular edema:Negative group (56 cases,100 eyes) and positive group(33 cases,55 eyes).In addition,23 cases (42 eyes) of normal volunteers constituted the normal control group.All the objects accepted an optical coherence tomography examination and the indexes including central retinal thickness (CRT),subfoveal choroidal thickness (SFCT) and integrity of external limiting membrane(ELM) as well as inner/outer segment (IS/OS) were measured and analyzed.Results The average CRT of positive group (219.048±16.798)μm was significantly thicker than that of control group(217.775±26.866)μm and negative group(280.418±74.187)μm (P<0.001).Mean SFCT among control group (312.893±140.559)μm,negative group (302.080±125.287)μm and positive group (293.745±140.517)μm had no statistical significance (P=0.781).There were 3 eyes with disrupted ELM layer in the negative group and 8 eyes in the positive group.Difference between them was proved to be significant (P=0.019).Similarly,the integrity of IS/OS layer had significant difference between negative group (5 eyes disrupted) and positive group (19 eyes disrupted) (P<0.001).Conclusion CRT of patients with diabetic macular edema is always increased and the integrity of ELM or (and) IS/OS can be disrupted in many cases.Indexes including CRT and the integrity of ELM or (and) IS/OS can be used to evaluate the severity of diabetic macular edema quantificationally.
