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.
光学相干断层扫描是一种新颖的、非侵入性的、非接触式且可重复的成像技术，它能生成眼部组织的高深度分辨率横截面断层图像。其价值在于能够获得目标组织的伪组织学图像。它基于光学原理，类似于超声B超检查，与激光反射测量法相似。光学相干断层扫描包括将低强度红外光照射在组织样本上，以及使用干涉仪和计算机成像系统。光学相干断层扫描最具吸引力的应用领域是视网膜疾病，如：中心性浆液性视网膜病变、黄斑裂孔、慢性黄斑水肿、年龄相关性黄斑变性。
