Multicolor imaging (MCI) is one of the latest in a series of upgrades to color fundus photography (CFP) in recent times. Fundus photography has been a very important tool for clinical fundus examination, surgical decision, teaching, involving patients in their treatment decision making, and documentation purposes. Standard color photography has been the gold standard for the same for over 50 years, and different platforms, both for examining 30–50 degrees of macula, widefield and ultra‐widefield view of the retina, have been developed. Recently, en face multicolor imaging has been available as an additional component of Spectralis SLO‐optical coherence tomography (OCT). Spectralis SLO uses three laser wavelengths, namely blue (486 nm), green (518 nm), and near‐infrared (815 nm), to scan the retina and create a pseudocolor image by combining the three bands. The monochromatic images are also separately available; blue light delineates the superficial retinal structures, green captures the vascular details better, and the near‐infrared laser images the deeper structures such as the inner retina and choroid. Therefore, the pseudocolor combined image resembles the image obtained by Optos wide‐angled photography as well.
