[Optical coherence tomography]

Optical coherence tomography is a novel, noninvasive, noncontact and repetitive imaging technique which produces high depth resolution cross-sectional tomographs of ocular tissue. It's value is given by the possibility of achieving pseudo-histological images of the target tissue. It is optically based, analogue to ultrasound B-scan examination and similar to laser reflectometry. Optical coherence tomography involves shining low-level infrared light on a tissue specimen, an interferometer and a computerized imaging system. The most attractive applications of optical coherence tomography are the diseases of the retina such as: central serous retinopathy, macular hole, chronic macular edema, age-related macular degenerescence.
