Optical coherence tomography (OCT) is a non-invasive imaging technique which uses reflected light to create high resolution, two or three dimensional representation of retinal architecture. Measurement of the various retinal layers allows for objective, quantitative assessment of structural damage in the visual pathway. OCT has therefore emerged as a non-invasive and relatively inexpensive technique for capturing loss of central nervous system axons and neurons. Because of these advantages, OCT is now being explored as a potential tool to identify retinal changes in patients early in the course of NDDs, and to allow quantifiable, objective monitoring of axonal and neuronal loss with disease progression.
