Multimodal imaging of angioid streaks

Abstract

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.
