- Abstract
The last decade have witnessed a tremendous advancement in retinal and choroidal imaging technologies thanks to improved light sources, detectors and high speed computers which are continuously improving. There are many examples as Fundus autofluorescnce is a relatively novel imaging method that allows topographic mapping of lipofuscin distribution in the retinal pigment epithelium cell monolayer as well as of other fluorophores that may occur with disease in the outer retina and the subneurosensory space. Optical coherence tomography is a method of using lowcoherence interferometry to determine the echo time delay and magnitude of backscattered light reflected off an object of interest. This method can be used to scan the retina with very high axial resolution. Optical coherence tomography angiography (OCTA) is a new non-invasive imaging technique that employs motion contrast imaging to get high-resolution volumetric blood flow information generating angiographic images in just a few seconds. OCT is undergoing another transformation with Multicolor technology by combining with confocal scanning laser ophthalmoscope t to acquire images using data from three simultaneous lasers red, green and blue taking advantage of the different wavelengths of each of these colors to image 3 different zones of the retina .
