目的：探讨18 MHz彩色多普勒超声对黄斑前膜的诊断价值。

方法：收集2020-01/2022-01期间在我院经眼底检查拟诊白内障和玻璃体混浊的患者44例80眼，分别通过光学相干断层扫描法(OCT)与18 MHz彩色多普勒超声对患眼进行检查，比较18 MHz彩色多普勒超声与OCT对黄斑前膜诊断敏感度、特异性、准确度的差异。

结果：经18 MHz彩色多普勒超声检测80眼中，62眼为黄斑前膜，18眼为非黄斑前膜； 经OCT确诊确实为黄斑前膜的54眼，非黄斑前膜的13眼，漏诊5眼，误诊8眼； 18 MHz彩色多普勒超声与OCT诊断一致性较高(Kappa=0.892，P<0.05)； 18 MHz彩色多普勒超声检测黄斑前膜敏感性为92%，特异性为62%，漏诊率为8%，误诊率为38%，正确率为84%； 与OCT检测相比，18 MHz彩色多普勒超声检测特异性、正确率、阳性预测准确率、阴性预测准确率降低，误诊率升高(均P<0.05)，诊断敏感性与漏诊率比较无差异(均P>0.05)。

结论：18 MHz彩色多普勒超声对黄斑前膜病变具有一定鉴定价值，与OCT检验具有一致性。

METHODS: A total of 44 cases(80 eyes)of patients with proposed diagnosis of cataract and vitreous opacity by fundus examination in our hospital between January 2020 and January 2022 were collected, and the affected eyes were examined by optical coherence tomography(OCT)and 18 MHz color Doppler ultrasonography, and the differences in the diagnostic sensitivity, specificity, and accuracy were compared between 18 MHz color Doppler ultrasonography and OCT for the diagnosis of epiretinal membrane.

RESULTS: In the 80 eyes detected by 18 MHz color Doppler ultrasonography, 62 had epiretinal membrane and 18 had non epiretinal membrane. Totally 54 eyes were confirmed to have epiretinal membrane by OCT, 13 eyes were not diagnosed with epiretinal membrane, 5 eyes were missed diagnosis, and 8 eyes were misdiagnosed. The diagnostic consistency between 18 MHz color Doppler ultrasonography and OCT was high(Kappa=0.892, P<0.05); the 18 MHz color Doppler ultrasonography detection sensitivity of epiretinal membrane was 92%, specificity was 62%, missed diagnosis rate was 8%, misdiagnosis rate was 38%, and accuracy was 84%; compared with OCT detection, 18 MHz color Doppler ultrasonography detected a lower specificity, correct rate, positive prediction accuracy, negative prediction accuracy, and higher misdiagnosis rate(all P<0.05), and the difference in diagnostic sensitivity compared with leakage rate was not statistically significant(all P>0.05).

CONCLUSION: 18 MHz color Doppler ultrasonography has some value in identifying epiretinal membrane lesions and is consistent with OCT testing.
