I couldn’t help borrowing this picture. It is a beautiful example of the future of imaging in eyecare. While this is not an example of optical coherence tomography, it is a good example of  the type of details we can expect in the future.

Fort Collins Eye Doctors Explanation

Optical coherence tomography splits a laser into multiple wavelengths that interact with the retinal tissues and gives incredible views of the retina we have never had before in a non invasive procedure. Look for this in the coming years to allow much earlier and accurate diagnosis of retina problems in the eye. This is a microscope picture of the retinal pigmented epithelium, the retinal layer that provides nourishment to the light receptor cells.
