Optical Coherence Tomography (OCT)
Optical coherence tomography (OCT) is a non-invasive imaging technology used to obtain very high resolution cross-sectional images of the retina at the back of the eye. Unlike ultra sound, OCT uses light rather than sound to generate and image. OCT measures the retinal nerve fiber layer thickness in glaucoma and other diseases of the optic nerve. It is the most accurate way to detect, diagnose, monitor and manage macular degeneration and other retinal conditions.
