A combination of high-penetration spectral-domain optical coherence tomography (central wavelength: 1,020 nm) and an enhanced depth imaging protocol (HP-EDI-OCT) was used to evaluate 5 eyes of 5 patients with polypoidal choroidal vasculopathy (PCV). In all eyes, HP-EDI-OCT provided high-contrast images of PCV lesions in the subretinal pigment epithelium (sub-RPE). In the space between the RPE line and Bruch's membrane, various PCV lesions, including vascular networks, polypoidal lesions, and sub-RPE hemorrhage, were clearly identified. The chorioscleral interface was clearly observed, and the entire structure of the choroid was readily identified. Thus, HP-EDI-OCT was useful for evaluating sub-RPE lesions of PCV.
采用高穿透光谱域光学相干断层扫描（中心波长：1020 nm）与增强深度成像协议相结合的方法（HP-EDI-OCT）对5例息肉样脉络膜血管病变（PCV）患者的5只眼进行评估。在所有眼中，HP-EDI-OCT均能提供视网膜色素上皮下（sub-RPE）PCV病变的高对比度图像。在视网膜色素上皮（RPE）线与布鲁赫膜之间的间隙中，能够清晰识别出各种PCV病变，包括血管网络、息肉样病变和RPE下出血。脉络膜巩膜界面清晰可见，脉络膜的整体结构也易于识别。因此，HP-EDI-OCT有助于评估PCV的RPE下病变。
