Optical Coherence Tomography (OCT) is a non-invasive imaging test that takes cross-section pictures of the layers of your retina. An OCT scan helps to see what’s going on beneath the surface of your eye, with these images your Doctor can then map out the layers and measure their thickness. The optic nerve head is also visible at the back of your eye, so an OCT scan can also evaluate any disorders of the optic nerve.
