Fundus Photography: Optical coherence tomography (OCT) is an imaging technique that uses low-coherence light to capture micrometer-resolution, two- and three-dimensional images from within optical scattering media (e.g., biological tissue). It is used for medical imaging and industrial nondestructive testing (NDT).
FUNDUS PHOTOGRAPHY. A digital fundus camera is used to take an image of the fundus — the back portion of the eye that includes the retina, macula, fovea, optic disc and posterior pole. … The resulting image can then be used by an ophthalmologist for diagnosis and treatment.
