Angioid streaks (AS) are irregular crack-like dehiscences in Bruch's membrane that are often associated with atrophic degeneration of the overlying retinal pigment epithelium. We herein report multimodal imaging of AS. Multicolor imaging highlighted AS in dark orange color. AS were better visualized in infrared reflectance as compared to green reflectance and blue reflectance. Peau d'orange appearance was seen as alternating dark and bright patches on color fundus photography with corresponding hyporeflective and hyperreflective patches on infrared reflectance. Comet lesions showed increased signal on infrared reflectance and hyperautofluorescence. Multicolor imaging is a non-invasive imaging modality which helps in clearly delineating these lesions.
血管样条纹（AS）是 Bruch 膜中不规则的裂纹样裂开，常与上方视网膜色素上皮的萎缩性变性相关。我们在此报告血管样条纹的多模态成像。多色成像将血管样条纹突出显示为深橙色。与绿色反射和蓝色反射相比，血管样条纹在红外反射下显示得更好。在彩色眼底照片上，橘皮样外观表现为明暗交替的斑块，在红外反射下有相应的低反射和高反射斑块。彗星样病变在红外反射下信号增强且自发荧光增强。多色成像是一种非侵入性成像方式，有助于清晰地描绘这些病变。
