Optical Coherence Tomography: Basic Concepts and Applications in Neuroscience Research

Figure 6

High-resolution images of the internal retinal structure taken with optical coherence tomography (OCT). (a) Low-coherence infrared light is transmitted into the eye through use of an interferometer. (b) The infrared light is transmitted through the pupil and then penetrates through the nine transparent layers of the retina. (c) A fundus image from the optical coherence tomography (OCT) device showing the optic disc appropriately centered and surrounded by the target image circumference marker for analysis of the retinal nerve fiber layer (reprinted with permission from [64]).
