How does optical coherence tomography work

WebOptical coherence tomography (OCT) is a non- invasive optical imaging technique that uses low-power infrared laser light to image up to 2 mm beneath the skin surface. The clinician can obtain real-time images of the architecture of the skin without pretreatment or gels. WebOptical Coherence Tomography is a noninvasive imaging technology used to obtain high resolution cross-sectional images of the retina. The layers within the retina can be differentiated and retinal thickness can be measured to aid in the early detection and diagnosis of retinal diseases and conditions.
