光学相干断层扫描血管造影(OCTA)可能是检测新生血管性年龄相关性黄斑变性(nAMD)中脉络膜新生血管(CNV)的有效工具,可以在大多数情况下分析CNV的类型、形态和延伸。 与荧光素血管造影 (FA) 和吲哚青绿血管造影 (ICGA) 相比,确定 OCTA 在检测继发于 nAMD 的 CNV 方面的敏感性和特异性。 前瞻性观察研究。 2016 年 5 月至 12 月期间招募了疑似 nAMD 患者。患者接受了 FA、ICGA、频域 OCT 和 OCTA(AngioVue,Optovue,Inc.)。使用或不使用 ICGA 评估 FA 的敏感性和特异性,并与 OCTA 进行比较。 纳入 70 名连续患者的 70 只眼:I 型 CNV 32 只眼(45.7%),II 型 CNV 8 只眼(11.4%),III 型 CNV 4 只眼(5.7%),I 型和 II 型混合 CNV 6 只眼(8.6%),无 CNV 20 只眼(28.6%)。 OCTA 的敏感性为 88%,特异性为 90%。 FA/ICGA 和 OCTA 之间的一致性非常好(0.91;范围 0.81–1.00)。 OCTA 对 CNV 检测显示出高灵敏度和特异性。 OCTA 和金标准染料技术之间的一致性非常好。 OCTA 可能是诊断 nAMD 的一线无创方法。
Optical coherence tomography angiography (OCTA) could be a valid tool to detect choroidal neovascularization (CNV) in neovascular age-related macular degeneration (nAMD), allowing the analysis of the type, the morphology, and the extension of CNV in most of the cases. To determine the sensitivity and specificity of OCTA in detecting CNV secondary to nAMD, compared to fluorescein angiography (FA) and indocyanine green angiography (ICGA). Prospective observational study. Patients with suspected nAMD were recruited between May and December 2016. Patients underwent FA, ICGA, spectral domain OCT, and OCTA (AngioVue, Optovue, Inc.). Sensitivity and specificity of FA, with or without ICGA, were assessed and compared with OCTA. Seventy eyes of 70 consecutive patients were included: 32 eyes (45.7%) with type I CNV, 8 eyes (11.4%) with type II CNV, 4 eyes (5.7%) with type III CNV, 6 eyes (8.6%) with mixed type I and type II CNV, and 20 eyes (28.6%) with no CNV. Sensitivity of OCTA was 88% and specificity was 90%. Concordance between FA/ICGA and OCTA was very good (0,91; range 0,81–1,00). OCTA showed high sensitivity and specificity for detection of CNV. Concordance between OCTA and gold-standard dye-based techniques was excellent. OCTA may represent a first-line noninvasive method for the diagnosis of nAMD.
