Optic disc drusen (ODD) are calcified deposits at the anterior optic nerve that are often detectable by ophthalmic imaging, including optical coherence tomography and fundus autofluorescence imaging. Multicolor (MC) imaging is a novel modality that captures reflectance of blue, green, and near-infrared laser lights with confocal scanning laser ophthalmoscopy to rapidly acquire high-resolution reflectance images of the optic disc and retina. Here, we show an eye with 3 MC imaging features of ODD, including prominent green hyperreflectance of the optic disc, green sheathing of the papillary and peripapillary vasculature (arterioles > venules), and presence of orange superficial ODD. MC imaging can provide rapid high-resolution assessment of eyes with optic nerve head elevation to help distinguish pseudopapilledema vs papilledema in children and adults without dilation, and future large studies incorporating MC imaging will help determine its contribution in the diagnosis and monitoring of ODD and assessment of other causes of optic nerve head elevation.
