Abstract
Recent technological achievements allow modification of both the range and number of different wavelengths used for posterior segment imaging. This range includes mostly visible and infrared spectrum, which can be used as monochromatic or multispectral mode. The main advantage of such imaging results from the fact that different wavelengths penetrate the retina at different depths and demonstrate details of the various layers of the retina. In CSC, the most valuable monochromatic mode represents by IR-reflectance, a method based on reflection and scattering of IR light by melanin, allowing evaluation of retinal pigment epithelium and, partially, choroid. In the row from red to green and to blue monochromatic imaging, the penetrative ability decreases and these wavelengths highlighted retinal pigment epithelium/choroid, retinal microcirculation, and vitreoretinal interface, respectively. A combination of these wavelengths as well as with different other wavelengths is known as multispectral (including pseudocolor) and hyperspectral imaging. The role of the latter in studying of CSC should be investigated further.
