Multicolor imaging in optic disc swelling

Abstract

Differentiating optic disc edema (ODE) from pseudo optic disc edema (PODE) continues to pose a diagnostic dilemma. Current report highlights the role of multicolor imaging (MC) in differentiating ODE from PODE. Composite multicolor images of the disc in ODE show greenish hyperreflectance that extends beyond the optic disc margins with irregular blurry margins and obscured disc vasculature whereas PODE shows a greenish hyperreflectance with clear and distinct margins and well delineated disc vasculature. MC imaging adds to the present armamentarium of imaging modalities obviating needless neurological evaluation mandatory in a case of true disc edema.

Validation of multicolor imaging signatures of central serous chorioretinopathy lesions vis-a-vis conventional color fundus photographs

“…MCI has shown promising imaging capabilities in various retinochoroidal diseases such as epiretinal membrane, age-related macular degeneration, and optic disc changes. [ 13 14 15 ] MCI was better in delineating epiretinal membrane than conventional color fundus photography. [ 13 ] It was better in identifying various lesions of posterior segments such as geographic atrophy and optic disc swelling compared to CFP.…”

Measurement of size of pigmented choroidal nevus: Superiority of multicolor imaging compared to conventional color fundus photography

“…Multicolor imaging (MCI) available on Spectralis spectral domain optical coherence tomography (SDOCT) platform developed by Heidelberg Engineering, Germany is a new imaging modality that provides pseudocolor coding of various fundus lesions and has been used in various retinal disorders. [ 2 3 4 5 6 7 8 ] MCI is based on confocal scanning laser ophthalmoscopy principles and uses three laser lights (blue 488 nm, green 515 nm, and infrared (IR) 820 nm) to image the retina. [ 4 5 6 7 ] Blue channel images the vitreoretinal interface and retinal surface, green channel is meant for imaging inner retinal features such as hemorrhage, hard exudates and blood vessels, and IR channel images retinal pigment epithelium and choroid.…”

Multicolor imaging for retinal nerve fiber layer defect in glaucoma

“…Utility of MCI has been described in various disorders such as epiretinal membrane, age-related macular degeneration, and ONH edema. [ 6 7 8 ] MCI signatures of RNFLD are yet to be described. The present report highlights the role of MCI in the detection of RNFLD in patients with glaucoma.…”
