光学相干断层成像术（ＯＣＴ）是一种新的无创伤的检查方法，可对眼球结构进行观察。对视网膜的断层成像为其最大特点之一，ＯＣＴ系统可将视网膜的神经纤维层、色素上皮层与其它细胞层面清晰分辨并进行定量测量。本文对ＯＣＴ的工作原理，眼部结构的正常ＯＣＴ表现，及病变的ＯＣＴ表现如老年性黄斑变性、中心性浆液性脉络膜视网膜病变、黄斑前膜、黄斑裂孔等，以及糖尿病性视网膜病变、视网膜血管阻塞、视网膜创伤、视网膜神经纤维层缺损等进行了综述
Optical coherence tomography (OCT) is a new noninvasive method of examining the structure of the eyeball. Tomography of the retina is one of its most prominent features. The OCT system clearly distinguishes and quantitates the retinal nerve fiber layer, the pigment epithelium, and other cellular layers. In this paper, the working principle of OCT, ocular OCT normal ocular manifestations and lesions OCT such as age-related macular degeneration, central serous chorioretinopathy, macular degeneration, macular hole, as well as diabetic retinopathy, retinal vascular Obstruction, retinal trauma, retinal nerve fiber layer defects were reviewed
