Abstract
Multicolor (MC) imaging is an innovative pseudocolor fundus imaging modality based on confocal scanning laser ophthalmoscopy. It effectively scans the retina at different depths to create a composite image. The green reflectance image depicts the middle retinal while blue reflectance image provides images of the retinal surface. The infrared reflectance image depicts retinal structures at the level of outer retina and choroid. We systematically analyze published case reports, case series, and original articles on MC imaging where it has helped in discovering additional clinical features of retinal diseases not readily apparent on conventional color fundus photography and played a role in monitoring the response to treatment.

Abstract
Astrocytic hamartoma is a benign glial tumor. It may be associated with tuberous sclerosis and can also be found incidentally on retinal examination as an isolated presentation. Here, we describe multimodal imaging characteristics of astrocytic hamartoma in a patient with retinitis pigmentosa. Spectral domain optical coherence tomography of both eyes showed moth-eaten optically empty spaces and hyperreflective dots along with foveal thinning. Multicolor image highlighted mulberry appearance of the lesion with green shift signifying elevated lesion. In infrared reflectance, lesion was hyporeflective with its margins well delineated. Green reflectance and blue reflectance highlighted calcification as multiple hyperreflective dots. Autofluorescence showed typical hyperautofluorescence.

Abstract
ABSTRACT 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.
