OCT: Optical Coherence Tomography (OCT) is a non-invasive imaging technique relying on low coherence interferometry to generate cross-sectional imagery of ocular tissues.This commonly performed test provides useful anatomic and functional information about the retina and is one of the most important tools in the diagnosis and treatment of retinal disorders. As the blood circulates through the retina, a series of rapid, sequential photographs are taken of the eye.
