Optical Coherent Tomography (OCT) is a new medical diagnostic imaging technology which can perform cross-sectional or tomographic imaging of the retina. The operation of OCT is analogous to ultrasound B-mode imaging or radar except that light is used rather than the sound of radio waves. Combined with conventional clinical techniques of direct and indirect ophthalmoscopy and fluorescein angiography, this offers us another powerful diagnostic tool to aid in patient care.
